crank

[bye_all_c_ya]

i need my crank grinding inc bearings where is best in the west midlands?

ctm are good to deal with but the postage will be £££
autosprint are also well renown
spinning a crank can cost quite alot why not try to source a good used item?

thats what im starting to do
ive got new 0.25 bearing so a crank to match would be great

[youngscottie]

why dose your old crank need ground?
if youve spun a shell or the bigends have been knocking have your conrods checked

sparkie came to build engine for me 2day polished crank (which came out of the engine before taking apart which worked fine)
new bearings, once all bolted up the crank was really hard to turn and he did about 15 turns and bearing was getting shiney score marks in them so somethink is wrong

bearing was .25 as was the old ones but i have x2 std bearing which confusses things ? so best getting new crank and starting again

best get a mic and measure the crank
the first time i had pistons fitted the guy who done them bent a rod ever so slightly
when bolted up ot the crank it locked the engine(now i do my own)
free your rods of one at a time and find out which ones are tight also
if you dont have a mic buy some plastigauge
