Engines & parts

Perkins 4.108 parts: good

Factory standard engine — you entered “Perkins 4.108”

Out of production but very well supported. Trans Atlantic Diesels (TAD) sells complete aftermarket rebuild kits (pistons, liners, rings, bearings, gaskets, valves, guides, seals), heads, blocks, crankshafts, genuine Perkins camshafts, rebuilt injection pumps and injectors, Jabsco/Sherwood raw water pumps, heat exchangers, starters, alternators and elbows, plus rebuilt exchange engines. The Westerbeke 4-107/4-108 family and some industrial engines share the base design.

Common problems (1)
  • Rear main (crankshaft) seal leak engine
    The original rope-type rear seal is notorious for leaking and often starts leaking again a few hundred hours after replacement; Foley sells a nylon/Teflon replacement seal meant to cure it, and owners check the crankshaft sealing surface for pitting.
