Crank probs

[halesworthlambretta]

Help needed - fitted new crank to Spanish SX engine last night. The bottom of the con rod appears to be proud of the crank webs and at a certain point is catching on the engine case.

Any advice would be much appreciated

Cheers

Is it a standard type 58 stroke 107mm rod? also, was the mag housing fitted?

[Rich Oswald]

Sounds like you could have a 60mm stroke crank?

Hi all - it's a 58 x 107

[halesworthlambretta]

Hi Coaster - yes we fitted the mag housing

Hi Coaster - yes we fitted the mag housing

What's the origin/make of the crank and are you sure it's rubbing at the big end eye and not on a poorly seated bearing retaining plate?

[Adam_Winstone]

I've only come across this with 60mm stroke cranks with standard rods

[halesworthlambretta]

All sorted - wrong size; Adam was spot on. (Thanks for that mate)

Should be back together for Mersea

Rich twigged to this before I mentioned it but between us we managed to give you a seconded opinion that helped you to identify the issue. Nice to be part of a community that helps each other out
