Engine Overhaul and Assembly Coverage

The Clark OH-339 and C500 service manual provides a structured look at the overhaul procedures for Clark (Waukesha) engine families. This documentation details the disassembly and reassembly of major engine components including cylinder heads, crankshafts, camshafts, and internal fuel systems.

Technical Reference and Specification Highlights

This Clark OH-369 technical manual incorporates extensive data tables for identification and clearance checks. The guide lists compression ratios, valve timings, and torque values for all critical fasteners, such as main bearings and cylinder heads. Manifold vacuum and cylinder compression testing parameters are documented to aid in diagnostic evaluation of the D155G, D155GA, and D176G power units. For those performing what an OEM service publication covers, the tables provide necessary tolerances for piston ring gaps, camshaft end play, and gear backlash measurements. All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work.
