🔌 Function

Carries the crankshaft in the block, holding it on its oil film under load.

⚠️ Common Signs of Failure

• Low oil pressure, particularly hot and at idle
• Deep rumble or knock from low in the engine under load
• Bearing metal or copper coloured flakes in the oil filter
• Shells scored, wiped or with the overlay worn through
• Crankshaft journals measuring outside specification

🛠️ Service Notes

• This is the standard size kit - the reground sizes are 3586873 at 0.25 mm oversize, 3586875 at 0.50 mm and 3586876 at 0.75 mm
• Have the crankshaft measured before ordering; the journal size decides the kit, not the engine hours
• Fit shells dry into clean saddles, oil the running face only, and tighten to the specified procedure
