Removing cylinder liners

(1/2) > >>

Seamus:
Anyone actually done this? Looks pretty straighforward.

I was thinking of replacing my over bored set with standard size. Moving them to the old block would save repainting and would look better as the 750 block is not in as good condition.

Cheers for any thoughts

K2-K6:
There was a thread going in the 400 section about this recently -can't recall the title- with some discussion and method amongst which was the need to machine the top of the barrels flat again after pushing the liners in.

UK Pete:
I heated up one of my cylinders in an oven when i took it out the liners just fell out, so they are reall easy to remove and fit, although you may have to get the tops machined to be sure they are flush in new block

Same here, I used 750 liners in my CB72, heated the block with a little gas blow torch and knocked em out. I've used the oven on others.

(the 750 block had all its fins smashed off by the PO in an accident, before folk get upset at the sacrilige ;D :D)

I also found that the heads on the liners were very accurate, the blocks' counterbores are machined very accurately so the liners heads are all the same, though its easy to check them with a micrometer/digital vernier

Seamus:
Thank you for your contributions. All looks fairly straightforward. Wonder if the wife would notice that I had a set of barrels in the oven? May get away with it when she is at work.

A little light cooking should have the things out.

Thanks again

Seamus
