Replacing Main Bearings

Wondering if I can get some advice / guidance.

I’m planning on replacing the rod bearings on the 4.3 V8. The engine will be in situ in the car. My thinking is that when I remove the rod cap, I can push the connecting rod up the cylinder chamber enough to refit the new bearings.

I’ve not replaced bearings before, is this likely to be a viable and easy proposition or am I likely to run into problems do you think ?



Thanks !!
 
I'm assuming you mean the big end shells.

As long as you can get the sump off (I've never worked on an SD1) it's not a bad job. You don't need to push the rod too far, I don't think I moved mine at all when I did them. I just turned the engine to BDC then removed a cap, replaced the shell in the cap, then carefully tapped the one in the rod until it dropped around the crank, and replaced that.

Are you doing the mains as well?
 
Thanks for the replies. It is indeed the shells I'm referring to. I think I have some knocking and it sounds like bearings. The car is actually a TVR and the sump can be dropped easily enough. Not an SD1 I grant you, but I find the help and expertise on this forum very use friendly. Thanks.
