Lister D White metal Big End bearing

ok, I have now taken it to bits further to clean it and repaint... so now its all in bits leaving a bare block bolted to the trolley........

anyway, the big end bearing white metal has worn down to the backing, to the exteme a last "sliver" of white metal fell off the shell...

now, it looks like the replacements are bronze copies.....

but... I have read elsewhere that they MUST be white metal and then machined.....

so, what do I do? fit a maybe not so perfect replacement new bronze bearing, or just put it back together with the worn old one....


i mean... its maybe better to have something worn and original that has already "worn" into the crank as opposed to a copy that may be worse than the old worn one....

Sounds like your stuck in the middle for what to do for the best. Problem being if your bearings are worn that much how much longer will they last as the end of the bearings life it starts to break up and parts of it stick to the cranshaft. But if your not running the engine that much will they last a few more years. Personally I'd go for the bronze ones as othes must have used them with some success and not all failures.

The bearings on ebay http://www.ebay.co.uk/itm/Lister-D-Oilite-Replacement-Big-End-Bush-/290892386968?pt=UK_BOI_FarmingEquipment_RL&hash=item43ba899298 are oilite and I have used these before. They are fairly easy to fit with the aid of engineers blue and a bearing scraper, the only thing that caused me hassle was removing the old bearing from the con rod. Hope this helps. Dan

yes, i see your point, and now having already "disturbed" the bearing... and had a little sliver of white metal come off already..... it is more likely that if I just reassembled it then it is of very limited life and could cause siezure to the big end crank journal.

I will go for a new bearing.

Personally I think your making the correct choice, for the price of the bearing a little bit of hard work they should see your lifetime out.

Keep us updated on how you get on,
