Part of the Yanmar Parts Manuals.
Need the factory part numbers for your Yanmar S165R skid-steer loader? This 100-page Yanmar S165R Parts Catalog PDF (OEM #0CS10-M56500EN) maps every component from mainframe and wheel drives through engine, fuel, exhaust, and brake systems, with exploded views and part numbers your dealer or supplier actually recognizes. Hydraulic coverage runs especially wide: tandem M44 pump, gear high-flow pump, lift and tilt cylinders, auxiliary circuit, self-leveling valve, and all control valve subassemblies, each broken out with its own exploded view and numbered parts list. Cross-check your engine configuration before ordering: low idle is 1200 ±50 RPM, high idle 3150 ±25 RPM. Ordering the wrong part kills a day or more. Bookmarked by system so you jump straight to hydraulic plumbing, any cab kit, or the full OEM accessory lineup in seconds.

Yanmar S165R Common Problems This Manual Covers
Yanmar S165R lift cylinder leaking oil, need correct seal kit part number p. 49
Turn to the Lift Cylinder exploded view on page 49. Identify the seal kit part number from the parts list — cross-reference your serial number range using the Reference Materials on page 2 to confirm compatibility. Order the seal kit listed, not individual seals, to get all O-rings and wipers sized for the 49mm bore.
Manual Section: Lift CylinderHydraulic hose blew on lift circuit, can't match the correct replacement fitting and hose assembly p. 24
Check the Lift Circuit Plumbing diagram on page 24. Each hose assembly and O-ring fitting is itemized separately — match the line call-out number to the parts list. Verify O-ring face seal (ORFS) versus JIC thread type before ordering; the diagram distinguishes them by fitting symbol. Cross-check with the Hydrostatic Plumbing overview on page 20 if the failed line runs near the pump.
Manual Section: Lift Circuit PlumbingDrive motor leaking or making noise, need part numbers for seals and motor assembly p. 51
Locate the Drive Motor and Parking Brake exploded view on page 51. The hydraulic drive motor seal kit is listed as a separate line item — order by that part number rather than individual seals. If the motor itself needs replacement, record the full assembly part number from page 51 and bring your serial number; the Reference Materials on page 2 confirm which serial range your motor assembly applies to.
Manual Section: Drive Motor and Parking Brake(Hydraulic Drive Motor)Engine won't start in cold weather, need glow plug and fuel filter part numbers p. 11
Find glow plug and fuel system component part numbers in the Engine and Engine Controls diagram on page 9 and the Fuel System parts list on page 11. The fuel filter is a separate line item on page 11 — note the part number and confirm thread pitch before ordering. The Air Cleaner diagram on page 12 lists the filter element separately if restricted airflow is also suspected.
Manual Section: Fuel SystemControl valve spool seals worn, bucket tilt slow or drifting, need seal kit part number p. 56
Go to the Main Control Valve diagram on page 56. The seal kit for the control valve spool is a listed line item — record that part number. If the tilt circuit specifically is drifting, also check the Tilt Relief Cartridge on page 62 and the Tilt Spool Positioner on page 60; each sub-assembly has its own seal kit listed separately. Cross-reference with Tilt Circuit Plumbing on page 23 to identify any hose or fitting parts also needed.
Manual Section: Main Control Valve(Control Valve)Tires worn unevenly or need replacement, can't find correct wheel assembly part number p. 41
Check the Tires parts list on page 41. Three wheel assembly configurations are listed: HD10X16.5 8PLY heavy duty, 10X16.5 6PLY standard, and 10X16.5 SD. Match your existing tire sidewall marking to the correct assembly line item before ordering — the part numbers differ between these three specs and are not interchangeable.
