This is the factory Service Manual for the Manitou Z17/170Z compact excavator, publication number 50940107, built around the Yanmar 3TNV70-XBV diesel engine. Across 400 pages it walks a mechanic through engine measurement and overhaul, the hydraulic system and circuit schematics, removal and reinstallation of the hydraulic pump, control valve, swing motor and swivel joint, plus the machine's electrical equipment and wiring.With it you can measure engine compression, set valve clearances, check fuel injection pressure, work the pump, valve and travel-motor repairs, and follow the wear limits that keep a mini excavator digging. The Technical Data and Service Standards chapters give the specifications, clearances and tightening torques, while a dedicated troubleshooting chapter helps you trace bucket drift, discontinuous arm movement and no-start faults. The file is a downloadable PDF you can search, print and keep on the shop computer or a tablet at the machine.

Manitou America Z17, Z170Z Common Problems This Manual Covers
Engine cranks but will not start
A dead battery, faulty starter motor, blown fuse or a safety-switch fault can all leave the engine turning over without firing. The engine start, stop and battery-charging circuit descriptions live in the Adjustment and Repair chapter.
Manual Section: Adjustment and Repair p. 265Weak or slow hydraulic functions
Low fluid, a clogged suction filter, air in the lines or internal pump wear show up as slow, weak or inconsistent hydraulics. Pump, control valve and swing-motor removal and reinstallation are covered here.
Manual Section: Hydraulic Equipment p. 127Bucket drifts down on its own
Natural release of the bucket and discontinuous arm movement are classic control-valve or cylinder-seal complaints. The Troubleshooting chapter separates these from normal non-breakdown behaviour and points to the cause.
Manual Section: Troubleshooting p. 361Tracks run too tight or wear fast
Improper track tension and worn rollers or idlers cause premature undercarriage wear and poor travel. The Service Standards chapter lists the roller and idler wear limits used to judge replacement.
Manual Section: Service Standards p. 33Engine overheats or loses power
A restricted radiator, low coolant or a stuck thermostat leads to overheating and lost power under load. The Engine chapter covers checking the cooling water system and radiator for leakage.
Manual Section: Engine p. 53Electrical circuit or accessory stops working
A blown fuse, damaged wiring or a charging-system fault can kill a single circuit or accessory. The parts layout, wiring diagram and monitor and alarm systems are documented in the Adjustment and Repair chapter.
