IMPORTANT:
Oil pump for Mitsubishi S6S — a 5.0L 6-cylinder diesel used across multiple OEM brands. Found in Mitsubishi forklifts (FD35-FD50), Hyundai excavators (R160LC), TCM forklifts, and Cat forklifts/excavators (under Cat 3066 designation). Supersedes 32B35-00011. Alt: 32B35-20010.
The #1 ordering mistake: confusing S6S (6-cyl, 5.0L) with S4S (4-cyl, 3.3L). These pumps are NOT interchangeable. Verify cylinder count on your engine nameplate. Failure symptoms: low pressure at hot idle, bearing knock at cold start that fades with RPM, oil pressure warning light on forklifts during tight turns (aerated oil). Internal gerotor with flange mount. Replace gasket and inspect pickup screen.
⚠️ Fits S6S (6-cyl) only — NOT S4S (4-cyl). Verify engine nameplate.
