I'm certain it's no longer available from SKF?

Re: 500 Left side main bearing
I have at least one. I'm in Bath. PM me. I'm keeping one back for my 500/5
Re: 500 Left side main bearing
I think my 501 has a modified main bearing. I have receipts for this but am currently many miles from home so cannot confirm. The original has an ID of 33 mm which is rare or extinct in the wild.
If you can get that one so much the better.
Otherwise and if I understand the situation options are
Get a replacement 33mmid bearing.
Get a modification to accept a 30mm ID bearing.
Get a bearing as above then get the vintage bearing co to modify it.

Re: 500 Left side main bearing
Wellll, I’ve got a new left side main bearing from MDina Italia which apparently is a modern replacement for the original. After having the new bearing pressed into the crankcases the next problem has arisen. The crankshaft, which I believe should just ‘slip in’ doesn’t. A few gentle taps don’t help! Help, any suggestions?
Re: 500 Left side main bearing
What is the OD of the crank journal
What is the ID of the bearing
I suspect there is a 3mm difference

Re: 500 Left side main bearing
I will be getting them measured at an engineering place in the next day or so ( I don’t have the tools for this) but a rough measurement wth a vernier gauge indicates a difference of about .25 of a mm.
Re: 500 Left side main bearing
OK- what are the numbers on your new bearing?
Accirding to my invoices mine looks to have been modified to accept a readily available size bearing, if/when it sees daylight I will know.
It says 240111Mod on the receipt in my file.

Yep, thats the one thats in it.
Re: 500 Left side main bearing
That is interesting . I’ll revisit my folder in case there is mention of either bearing or crank modification.
