FSA Cranks and BB

[Jimmy Welch]

Hi Guys I'm replacing the chainring ony pals Cannondale it's got FSA 46 chainring and self thingy crank pushers sorry picture attached , when I roved the crank there was 2 spacers on the non drive side one hard plastic and the other steel , the steel one seemed very out of shape , is is meant to be like that , or shall replace with nice round one

is it a press fit BB ?
some have a wavy pre load washer on the non drive side

Yep, it's a wave washer that helps with the preload, you'll get a new one with the BB if you replace it.

Yes it is , Im not replacing the BB so I'll put it back on , does it go on after or before the other spacer

 

[Jimmy Welch]

Also what would be the consequences of not replacing it

Put it on the left side last before fitting the arm.

Consequence would be improperly pre-loaded bearings in the bottom bracket and the crankset would have left to right play - you'd definitely notice this when riding.

I've never paid much attention other than making sure it's on.
