Part of the New Holland Repair Manuals.
Factory service manual for the TVT135, TVT145, TVT155, TVT170, TVT190 and TVT195 tractors with the SisuDiesel engine, spanning 135 PS to 190 PS rated power. Page 13 indexes power by engine type code (620.95 through 620.99) rather than by model name, so identify your machine from the engine plate. You get full engine teardown data (cylinder head bolts at 80 Nm plus 90 plus 90 degrees, crankshaft bearing bolts at 200 Nm, valve clearance 0.35 mm), common rail injection service including injector overhaul, the CC-LS closed center hydraulics, EDC hitch control, and transmission cartridge disassembly with SGR fault codes. The electrical chapters carry the real weight on these machines: wiring harness part numbers, a circuit diagram index by function group, and the ADIC fault code list with cause and solution for each code. Steering axle overhaul with torques, rear axle, parking interlock and cabin air conditioning round it out.
