has anyone fit L18 main bearins to and fj20 they are a perfect fit however the oil hole is slightly off. has anyone modified the oil hole before if so how hard is it to do?

I know you need to do it but I had it done at SWR so I'm fkn useless

the oil hole is only out very slightly i just dont wnt to damage the bearing in trying to elongate the hole in the bearing......has anyone done this b4 or had any problems fitting these bearings?

On main bearings 1 - 4, it isn't so much of an issue. There is a channel that runs around the bearing shell, so the oil isn't resticted significantly. On No. 5 though, there is no channel. The bearing hole needs to be in alignment for best oil delivery.

I use a needle file to elongate the hole. Just be patient. You can also use one of those Dremel-type grinders, but you need to be super-careful. Do not scratch the bearing surface, and make sure that there are no burrs whatsoever. Also, wash the bearing thoroughly afterwards. Try to not get any filings trapped in the lead coating.

Another thing worth noting is that there are a couple of different types of bearing shells - one has an oil groove in it; one doesn't. You want all of your (main) bearing shells to have this groove in it. It may mean purchasing 2 sets of bearings to get one set of bearings for your engine, but it is worth it.

I purchased ACL bearings for an L18, and had to buy 2 sets (the shells are mixed). I bought some Precision bearings, and they were all grooved. It just depends on the brand, I guess.

cheers thanks heaps for the help much appreciated
