Anyone know the big end and main journal sizes for a cossie crank?! Gotta order some shells for mine and just measured em with a digi caliper and the mains are 57mm bar the odd .something variance, and the big ends are 52mm .something variance lol.

Cheers

You coulda bloody cleaned it!!!

Cheers mate

 

It's a proper manual! No cheque book repairs here

 

odd thou, the main in the manual says 56.989 and the 1 i measured came out at 57.05 and the big end 51.977 and mine was 52.17

Guess there will be a slight variance with all of em, but from that guess it'll be standard size shells for me!!

Cheers

 

Your vernier caliper is probaly slightly out. Use a mike instead

Don't forget to check the bearing clearances with plastigauge and check the bearing 'crush' too (don't want any spun shells)

 

Well its a brand new digi caliper so should be pretty accurite!! Will measure each journal properly before i order the shells, whats a plastigauge?!

 

It's calibrated wire filaments that when sandwiched between the bearing shell become squashed. You then measure the width of the squashed wire and it gives the clearance.

It's a lot easier to use than to explain

 

a nice clean one any better ?
