🔌 Function

Supports the crankshaft in the block, carrying the running load on a pressurised oil film.

⚠️ Common Signs of Failure

• A deep rumble from the block under load
• Oil pressure low, especially at hot idle
• Bright metal or copper flakes in the oil filter
• Shells found scored, wiped or copper-showing at strip-down

🛠️ Service Notes

• Three Std D main bearing kits are listed here for MD engines with the same fitment count, this one and 876663 and 876666, so the grade marking alone will not identify the right kit; order by the number your parts book gives
• Its own undersize partners in this run are 876661 at 0.25 mm and 876662 at 0.50 mm; order by measured journal diameter, never by weight
