System Notes — BASIC ENGINE
The basic engine group covers the core structure and internals: cylinder block, cylinder head, pistons, rings, liners, connecting rods, crankshaft, bearings, camshaft and the gasket sets that seal them. These parts determine compression, oil pressure and power output. They wear gradually — rings lose tension, bearings show copper, liners glaze — and the first signs are usually blow-by from the breather, rising oil consumption, or a knock that gets louder as the engine warms. Replacing a basic engine part is a planned overhaul decision rather than a roadside fix, so matching the exact part number and serial number range matters more here than anywhere else on the machine.
System Notes — UNDERCARRIAGE
The undercarriage group covers tracks, shoes, links, bushings, rollers, idlers, sprockets, track tensioners and the recoil hardware. It carries the whole machine weight and transmits drive force to the ground, and it is normally the single largest wear cost on a tracked machine. Wear is a system: a worn sprocket accelerates chain wear, a loose track pounds the bushings, and a seized roller flat-spots the link it runs on. Parts here are replaced on measured wear — bushing diameter, shoe height, roller flange — and replacing one component out of phase with the rest usually shortens the life of both.
