John Deere Engine Model Overview        
  1. John Deere manufactures a variety of engine models in six major series (300, 350, 400, 450, 500, 550). These engines may be offered as: (D) naturally aspirated, (T) turbocharged , (A) turbocharged & aftercooled ,(H) and turbocharged with air-to-air aftercooling. Engines sold loose for use in equipment other than John Deere have an (F) in the serial number.
  2. John Deere identifies their engine models by using the first digit to indicate the number of cylinders. The next three numbers indicate the displacement in cubic inches (Example: Model 6-414D is a six cylinder naturally aspirated engine with 414 cubic inch displacement). Sometimes the (-) is not included in the model designation (Example: 6414D). The newer metric engines are identified by number of cylinders and the displacement in liters. (Example: Model 6068T is a six cylinder, turbocharged engine with a 6.8 liter displacement).  Many engine parts used in metric engines are interchangeable with parts used in cubic inch engines.
  3.  John Deere began phasing in a new family of engines in 1994, which replaced the earlier models. These engines are called Powertech 350 and 450 Series engines. They are identified as: Models 2.9 Powertech, 4.5 Powertech, 6.8 Powertech and 8.1 Powertech . The Powertech engines have few interchangeable parts with the earlier models. Caution: Do not confuse these new model numbers with earlier models.  The 3029, 4045, and 6068 metric engine components are different from the Powertech 2.9, 4.5 and 6.8.
  4. John Deere engines have been manufactured around the world, mainly in these three locations:
    300 Series                   Manufactured in Dubuque, Iowa & Saran, France
    350 Series                   Manufactured in Saran, France & Torreon, Mexico
    400, 450, 500 Series   Manufactured in Waterloo, Iowa                                                       The 300 Series engines previously manufactured in Dubuque and Saran are essentially the same. Although the component parts in engines manufactured in both locations may be the same and are interchangeable, some parts carry different numbers. Reliance utilizes the part number that is more commonly used.
  5. John Deere utilizes the equipment model and serial number for identifying equipment, engines and parts. Many owners know their John Deere equipment only by model number and cannot identify their engine. A cross reference from John Deere equipment model numbers to John Deere engine models is included in the Reliance catalog.
 Reliance Parts Catalog Overview 
  1. Reliance part numbers are based on John Deere part numbers. A prefix or suffix is added to the John Deere number indicating the type of Reliance part:
    N -    Denotes a new Reliance part that is directly interchangeable with John Deere.
    E -    Denotes a Reliance remanufactured exchange part.
    RP -  Denotes a Reliance part for which there is no equivalent John Deere number.
    P –    Denotes a Premium part (Suffix)
    K-     Denotes a Kit (Suffix). Includes parts in addition to the John Deere equivalent part number.
  2. The Reliance Master Catalog is laid out in five sections by engine series (300, 350, 400, 450 & 500). Within each engine series section the parts are grouped by the type of part using a group numbering system similar to the one used by Detroit Diesel.
  3.  Within each parts group the parts are sorted in sequence by the specific engine model where they may be used. The number of cylinders is not shown in the reference, only the displacement. (Example: In the 300 Series – Model 152 would be followed by Model 164, then Model 179, etc.).
  4.  Parts may be identified by determining the engine model. John Deere adds a suffix to the engine model to identify when it is either: (D) naturally aspirated, (T) turbocharged,     (A) turbocharged and air to water aftercooled, or (H) turbocharged and air to air intercooled. If the engine model designation for a part in the Reliance catalog shows a “D”, “T”, “A”, “H”, it will only apply to that specific version of the engine. If it shows no suffix then that part will fit all versions of the engine.
  5.  To identify some parts it is necessary to also know the engine serial number (not equipment serial number), block casting number and/or the connecting rod forging number. If the catalog does not reference a serial number, block casting number or connecting rod forging number, the part will fit all engines in that specific model designation. If the serial number, block number or connecting rod number is shown in the catalog, then the part will apply only to the specific versions of the engine model identified by these numbers.  Only most common marking numbers are shown in catalog.  Call Reliance Customer Service for additional information.
  6.  In many instances Reliance will assign its own part number to kits and assemblies when there is no kit or assembly offered by John Deere. In some instances a Reliance part number is used because the kit offered by Reliance is more complete than the similar kit offered by John Deere. An example would be the Reliance cylinder kits, which include liner o-rings and piston pins, or Reliance engine overhaul kits, which include connecting rod capscrews, connecting rod bushings and camshaft bushings.  The standard John Deere kits do not. To compete, they later created “Expanded content Kits” which have additional parts.
 Reliance Parts Catalog -  Information by Parts Category

In order to identify the correct part number, information may be required in addition to the engine model. Modifications made to engines during their production years created parts variations. Options offered by Reliance are also included. Only those sections and engine series which require special comments are included below:

 Section 1.02             Gasket Sets – Cylinder Head and Overhaul

            All Series

  • Conversion sets are available which when combined with a pan set and head set will create an overhaul gasket set.

300 Series

  • Reusable molded rubber/ metal gasket included in gasket sets.

400 Series

  • A 6-404T engine used in the 4520 tractor w/air conditioning requires a NR-46158 front timing gasket.

Section 1.20             Cylinder Heads & Parts

300 Series

  • 45° valves are used in naturally aspirated engines. 30° valves are used in turbo engines.
  • Oversize stem diameter intake and exhaust valves are available.
  • 300 Series engines do not utilize replaceable valve guides

 400 Series

  • Oversize stem diameter intake and exhaust valves are available.
  • Running changes require identification by engine serial number; or head casting number using cylinder head application guide.
  • Early model 6-404D engines used in 4010 and 4020 tractors used different style cylinder heads. John Deere manufactured a “replacement block” which utilized the late model bearings and cylinder liners, but allowed installation of the early style cylinder head.

Section 1.30             Crankshaft, Bushings, Sleeves, Seals and Bearings

All Series

  • Crankshafts are sold separately.
  • Bearin pair, main includes one upper and one lower bearing.

300 Series

  • Order one Thrust Bearing set per engine plus the appropriate number of  bearing pair, main (3 sets for 3 cylinder, 4 for 4 cylinder and 6 for 6 cylinder engines).
  • Thrust main bearings are available with or without flanges. Flanged and flangeless bearings may be used interchangeably. If you order flangeless thrust bearings, also order thrust washers. Thrust washers are used with flangeless thrust bearings only.
    • Standard size thrust washers are sold individually. Order four per engine.

400 Series

  • Check crankshaft forging numbers to determine correct crankshaft.
  • Thrust main bearings are available only without flanges. Thrust washers must be used with flangeless thrust bearings.
  • Thrust washers are sold in sets, which include three washers. Order one set per engine.
  • Two of the three thrust washers should be installed with bearing cap; and the third on the rear (flywheel side) in the cylinder block.
  • Order one thrust bearing set per engine along with a set of three thrust washers, plus the appropriate number of bearing pair, main (3 sets for 3 cylinder , 4 for 4 cylinder and 6 for 6 cylinder engines).
  • Reliance bearings have only one oil supply hole while the engine block bearing journals have two holes. One hole is for supplying oil to the crankshaft. The other was used to facilitate the drilling of the orifice for the piston-cooling nozzle which receives oil from a separate oil passage in the block.  Current John Deere bearings also have only one hole.
  • Only flangeless type thrust main bearings with thrust washers are used in 400 Series.

       500 Series

  • Engines require six baring pair, main and one thrust bearing set.
  • Only flangeless type thrust main bearings with thrust washers are used in 500 Series.
  • Thrust washers are sold in sets, which include three washers. Order one set per engine.

 Section 1.60             Connecting Rods, Bearings and Rod Cap Screws

 All Series

  • Connecting rod bushings are available in two styles, one for honing & one for boring. The bushing suitable for boring has an “S” suffix on the number. The smaller inside diameter on the boreable bushing allows the rod center-to-center distance to be restored. John Deere does not offer a boreable type bushing.
  • Connecting rod bearing sets include one upper and one lower bearing. Order 3 rod bearing sets for 3 cylinder engines, 4 for 4 cylinder engines and 6 for 6 cylinder engines.
  • John Deere recommends that cylinder head bolts marked “special” and all connecting rod capscrews be replaced every time they are loosened. They are designed to stretch when properly torqued. If reused, proper clamping pressure will not be obtained, and premature failure may occur.

300 Series

  • Model 4-276D engines con rods were manufactured with two different piston pin diameters. Check con rod forging number to identify the correct size.
  • Early 164, 219 and 329 engines use smaller piston pins than later versions of these engines. If possible, check connecting rod forging numbers prior to ordering cylinder kits
  • Early versions of the 179, 239, and 359 engines were manufactured with different rod bolts than later versions. Check rod forging number and reference the parts catalog to determine the correct cap screw.

500 Series

  • Early 6-619A engines rods were marked R57484 or R66925. Reliance does not offer connecting rod bushings for these rods. By replacing the old rods with late model rods (AR79366), the mid range cylinder kits NRE20291 may be used. 

Section 1.62             Cylinder Kits

All Series

  • The engine serial number, block casting number and/ or rod forging number will be required in most instances in order to identify the correct kit.
  • Cylinder kits are pre-assembled. Rings are installed on the piston, the piston is inserted into the liner. Packaging identifies them with the name “Fac-Pak”.

300 Series

  • John Deere liner O-rings are normally located in the block. Very early model 152, 164, 202, 219, 303 & 329 engines had O-rings on the liner or in the block.   Later versions of these engines were manufactured with the O-ring in the block. Liner must be removed to identify location of O-Rings.  On 4-202/ 4-219 engines with blocks marked T26933 and T32342 check bore size to identify correct cylinder kit.
  • Early 164, 219 and 329 engines use smaller piston pins than later versions of these engines. If possible, check connecting rod forging numbers prior to ordering cylinder kits.
  • To determine the correct cylinder kit for model 4-276D engines, it must be determined if it has small or large diameter piston pins. Small pins were used in model 2630 and 2640 farm tractors only. Check connecting rod forging number and refer to the parts manual to determine correct kit.
  • John Deere redesigned the pistons in 179, 239 and 359 model engines by moving the top ring to 5/32” from the top of the piston (high ring ) to improve starting and reduce emissions. High ring and low ring cylinder kits can be used interchangeably – in complete sets only. Reliance offers both the High and Low ring designs for all 300 Series engines.
  • Cylinder kits with high compression pistons are available for late 164, 219 & 329 engines.

400 Series

  • Two kits are available for early model 6-404D engines used in 4010 and early 4020 tractors. One kit is required if the engine still has its original block. Another kit is used in engines which have had the block replaced with a John Deere “replacement” block. The “replacement” block is different from the original block. It permits the reuse of the original early style wide cylinder head but utilizes the late style main bearings and cylinder liners.
  • Some 6-404 engines have only one o-ring in the block. Reliance supplies two type o-rings; Duro-Silicone (Orange) and Duro-Viton (Black). The Duro-Viton has a higher heat resistance and should be used.
  • Optional Hyper-formance kits which include higher compression ratio, hypereutectic pistons are available for the 4-270D, 6-404D,T,A, and 6-466 T,A engines.

 Section 1.63             Engine Overhaul Kits

 All Series

  • The engine serial number, the block casting number and/ or the connecting rod forging number will be required in most instances in order to identify the correct overhaul kit.
  • Two types of engine repair kits are available:

Inframe Overhaul Kit – Includes bearings, upper & lower gasket set, connecting rod bolts and cylinder kits. John Deere does not offer inframe overhaul kits.

Major Overhaul Kit – Includes all parts required for an out of frame overhaul, including cylinder kits, overhaul gasket sets, connecting rod bearings, connecting rod capscrews, front and rear crankshaft seals, crankshaft bearings, connecting rod bushings, camshaft bushings ,plugs, and balancer shaft bushings where applicable. 

  • All overhaul kits may be ordered with undersize bearings by adding a -10, -20, or -30 suffix to the kit part number. Mixed size main and rod bearings may be ordered only for emergency drop shipment at regular price.

300 Series

  • John Deere liner o-rings are normally located in the block. Very early model 152, 164, 202, 219 & 329 engines had o-rings on the liner. The block casting number or engine serial number is required to determine the correct inframe or major kit.
  • Early 164, 219 and 329 engines use smaller piston pins than later versions of these engines.  If possible, check connecting rod forging numbers prior to ordering cylinder kits.
  • To determine the correct inframe or major kit for model 4-276D engines, it must be determined if it has small or large diameter piston pins. Small pins were used in model 2630 and 2640 tractors only. Check connecting rod forging number and refer to the reference material to determine correct kit.
  • 4030 Farm tractors require a special Pan Gasket which must be ordered in addition to the Inframe Overhaul Kit, or Major Overhaul Kit.
  • Overhaul Kits with High Compression Pistons are available for late 164, 219 and 329 engines.

400 Series

  • Two kits are available for early model 6-404D engines used in 4010 and early 4020 tractors. One kit is required if the engine still has its original block. Another kit is used in engines which have had the block replaced with a John Deere “replacement” block. The “replacement” block is different from the original block. It permits the reuse of the original early style wide cylinder head but utilizes the late style main bearings and cylinder liners.
  •    Optional “Hyper-formance” major overhaul kits which include higher compression ratio pistons are available for the 4-270D, 6-404D,T,A and 6-466T,A engines.
  • Optional overhaul kits are available for the 6-466T/A which include a premium head gasket.

 Section 1.70             Camshafts, Balancer Shafts and Related Parts

            300 Series

  • Camshafts operating in engines may have either a threaded or press-in type tach drive. Reliance offers only threaded type tach drives. All Reliance camshafts utilize a threaded tachometer drive. If a press-in type camshaft is being replaced with a new Reliance camshaft, a new threaded type tach drive must also be installed. The threaded type tach drives are available with either a slotted (NR81513) or helical gear type drive shaft (NR 81514). Determine which type drive shaft is required.
  • Camshafts are available individually or in kits which include a camshaft, and followers.

 Balancer shafts are used in 202, 219, 239, 276, and 4045 engines. There are both right and left hand balancer shafts.

  • Balancer shafts are sold only as asemblies, which include one balancer shaft, a gear and key.

 Section 2.10             Injectors

All series

  • Depending on engine model, injectors are available as new only.
  • Refer to the marking on the injector to identify the part number.

Section 4.10             Lube Oil System

300 Series

  • Various size oil coolers are used on 3-164, 3-179, 4-219, 4-239,  6-329, & 6-359 engines. The difference is in the number of cooling plates ( 6, 8, 10).

400 Series (Cam Driven)

  • Engine models 4-270D and early 6-404D engines utilized a two-piece oil pump drive gear and shaft. The gear (NR32428) is available but the shaft is not.

Section 5.00             Cooling System

All Series

  • Water pump repair parts are available as (1) overhaul kits, (2) reconditioning kits and (3) piece parts. Overhaul kits contain all of the parts necessary to rebuild a water pump. Reconditioning kits are the same except no impeller is included.
  • A wide variety of water pumps were used on the same engine model. The correct repair kit can be determined by identifying the casting number marked on the housing and referring to the water pump guides in the Reliance reference material.

 

Section 5.30             Thermostats

300 Series

  • A variety of thermostat housings and thermostats were used on these engines. The correct thermostat can be determined by identifying the casting number marked on the thermostat housing.
