I've got hold of a 1600 x-flow which I intend to recondition / tune to replace my 1100 unit.

I've taken the 1600 apart and found some wear on the crank which I didn't expect.

See picture!

It is a picture of the centre main centre bearing and the wear is caused by the thrust washer.

Is there anything that can be done with this crank? I'm assuming at the moment it is scrap!

Does anyone one know of a company that sells x-flow parts? Crankshafts, cams, cam followers, oil pump etc etc... I'm also looking for a company who could rebore by block and replace the valve seats to ones suitable for lead free petrol? I live near Bath...

check the shells you have taken out and see what in thou the shells are.If they aren't oversized in thou,you should be able to get it reground.Don't think that the parts are interchangeable between different X flow engines in CC's.The 1600 uses a taller block and longer stroke than the smaller cc engines.

The bearing shells are not oversized. That isn't ths bit i'm worried about. The main bearing surface isn't too bad - is needs a grind / polish to make it perfect.

My worry is the round shape worn into the crank side where the thrust washer goes. The thrust washer was flat against the bit that goes against the block (so I'm hoping the block is fine), but the washer was't flat against the crank - it was round. See the shape of the wear against the photo with the steel rule.

I don't know much about the history of the engine, but what could have caused this?

The other thrust washer and surfaces are perfectly flat...

Only thing I can think of is maybe the tin spacer between the gearbox and engine hasn't been fitted and the primary shaft of the gearbox has been pushing the crank forward.

As I type this I'm thinking if the clutch was over adjusted then when the pedal was depressed it could be pushing the release bearing so far in that that could also push the crank forward too.

I can't think of any other reasons why the crank would be pushed foward to cause that sort of wear, (time for the idiot question) was the bearing in the right way?

you can get oversized thrust washers,and if that is too far gone,then fluke motorsport have a crank,and flywheel all balanced for sale for £80.
