John Deere 4105 Compact Utility Tractor Technical Manual TM102419

The 4105 is a popular small tractor for acreages, landscaping and loader work, and TM102419 is the dealer technical manual for it. It's written for someone who does their own repairs and wants the real factory numbers rather than forum guesses.

Fits

John Deere 4105 compact utility tractor with the Yanmar 3TNV84T-BKJT 3-cylinder diesel. North American version, December 2010.

What this manual covers

It starts with specifications, identification numbers and the tools and materials you'll need. The engine section covers the 3TNV84T-BKJT in detail: bore and stroke, displacement, firing order, rotation, the direct injection system, then diagnosis and full repair. The electrical section has wiring schematics in two versions, because John Deere changed the harness and charging circuit during production. After that come PTO theory of operation and repair, hydraulics with specifications and schematics, and steering diagnostics, tests and repair. Torque values and wear limits are given throughout. The engine section is detailed enough for a head gasket, injector or full rebuild job, with clearances and torque figures listed at each step.

Who this manual is for

Owners who maintain their own tractor and small shops that see the odd 4105. Typical jobs include a no-start or charging problem, a weak or noisy PTO, slow loader hydraulics, and engine repair.
