Part of the New Holland Repair Manuals.
Arguments over S3L2 clearances end here: the 312 page New Holland S3L2 service manual PDF, OEM ID 84523916, is the factory document for this three cylinder diesel engine, whatever it happens to power. The fuel injection section takes up nearly a third of the book, running the pump from removal through timing to injector inspection and the shutoff solenoid. Wiring diagrams map the starting circuit, cold start aid, and alternator, so an electrical fault gets chased with the print in front of you instead of from memory. Before teardown, verify compression against the 26 to 29 bar (377 to 421 psi) spec, then measure standard bores against 78.030 to 78.060 mm. Guess a bearing clearance wrong and you pay twice: parts, then a second teardown. Buy this bookmarked, keyword searchable PDF once and it stays yours for the life of the engine.
