🔌 Function

Supports the crankshaft in the block where the main journals have been reground 0.75 mm undersize.

⚠️ Common Signs of Failure

• A deep rumble from the bottom of the engine on load
• Low oil pressure at hot idle
• Metal particles in the oil filter
• Shells found wiped or copper-showing on strip-down

🛠️ Service Notes

• This is the last regrind step; the group runs 876515 standard, 876516 at 0.25 mm, 876517 at 0.50 mm and this kit at 0.75 mm, and should be ordered by measured journal diameter rather than weight
• A crankshaft already at 0.75 mm undersize cannot be ground again, so check the journals for ovality and taper before rebuilding
