I used G Bland and Sons at Barnsley for all my engine machining last year. They were excellent and went to great lengths to get everything right. I had to have my block line bored for new bearing caps and the cam bearings fitted and bored as they were missing from my spare block (original block was the wrong one). I still have the crank seal tool I made for centering the seal carrier if you need it as mentioned before. Cheers. Tim.
i)The end float on the crank is 7 thou. I think that the recommended float is between 2 and 5 thou, so I'm a bit over, but is it enough to have to replace the shells which otherwise seem in good condition?
ii) The crank has been reground to 30 thou and the surfaces seem in good condition.
iii) End float on the big ends is about 14 thou. I've not seen any discussion of end float for these so I don't know if it matters as presumably the pistons sitting in the bores centre them anyway (plus they must need at least the same end float as the crank to stay centred on the cylinder bores when the crank moves). As near as I can work out, there is 4 thou play between the big end shells and the crank. I need a new set of big end shells anyway, so some of that will probably be taken out.
iv) After I cleaned it up, there was 9 thou play between the camshaft and the front bearing (the one in the earlier pictures). That seems like too much so I'll need a new one, which is a pity as it cleaned up quite well.
I'm going to have to find other jobs to do on the restoration now as I'm stuck on progress with the engine until I find an engine shop that's open.
