Changing Main Bearing - Engine in Situ

jt_armstrong · Dec 3, 2011

Looking for some advice.

I am planning to change the main bearing shells without removing the crankshaft. There are plenty of threads on the formum describing how this can be done however none mention if you need to remove the 5 bolts (on each side) which come in from the side of the engine at 90 degrees to the main bearing cap bolts.

Do these also need to come out just to remove the bearing cap?

Try taking the caps off with them in. I think that will answer your question.
See RAVE to torquing instructions.

I take it you have checked the sizes. And got the correct sized bearings. Size will be stamped on shells.

Of course doing it in situ, you're taking the crank end-float for as a given, also, it's not possible to spin the crank to get a feel for whether they're seated properly either unless you've removed the heads and pistons, what about the notorious rear crank-seal? If your current one doesn't leak then you're the luckiest Rover V8 engined vehicle owner alive!

I hope I have. The replacement set I got are marked standard. I know the crank has not been ground. The old shells dont have standard on them just G and D in a box and DD next to it.

They will be standard then. They would be marked with the undersize if they were.
