NOTE A- This number is for reference only. The Reman consist does not exactly match any production part.
NOTE B- Crankshaft is positioned at top dead center, number one firing, before shipment.
NOTE D- Core Plugs in rear face of Cylinder Heads may not match the customer's application. Form SEHS9776 is attached to rear of Cylinder Head.
NOTE E- The Lifting Group is for handling during installation and removal from shipping container. The customer may have to use the Lifting Eyes from the removed engine. Form SEHS9666 is attached to the Rear Eye.
NOTE F- This Valve Cover Group is for debris protection. The customer will have to use the Valve Cover Lids from the removed engine. Form SEHS9665 is attached to the Front Valve Cover Lid.
NOTE G- With 40 mm Injector Nozzle Adapters for use with later, long, thin, "PENCIL" style Fuel Injector Nozzles (Ref. Nozzle P/N's: 4W7018, 4W7019, and 4W7020). The Injector Nozzles are not included with the Long Block.
NOTE H- With 55 mm Injector Nozzle Adapters for use with short, fat, "CAPSULE" style Fuel Injectors (Ref. Nozzle P/Ns: 4W7012, 4W7013, 4W7014). For more information see: "New Cylinder Heads and Fuel Nozzle Adapters Used", Engine News, July 1985 (and Supplement:4/00/86). The Injector Nozzles are not included with the Long Block.
NOTE J- "Thick/Cheek Web" Crankshaft. This crankshaft, together with the later Cylinder Block, is intended to service early style engines. Do not reject this long block as a candidate just because the Crank and Block part numbers do not match the customer's engine. The parts in the Long Block match each other. Older Style Flywheel Housings will have to be machined to provide clearance for the thick cheek crankshaft. (see: Service Magazine 14 December '87 "Earlier Flywheel Housings Can be Modified for Use with Later Crankshafts" and Service Magazine 13 May '85 "New Crankshaft, Cylinder Block and Camshaft Used"). Heavy duty Rear Gear Group Applications will require exchanging the Rear Gear Group and/or Balancer.
* Use of 0R4278 Long Block for 988F Wheel Loaders having engine serial numbers before 48W40078 requires conversion of Front Gear Train to a helical design. Effective with engine serial number 48W40078, the Front Gear Train contains Helical Gears, and 0R4278 Long Block can be used by transferring components from the production engine, including the 4P3581 Rear Gear Group.
