Conrod

[toonarmy]

Hi all,

Stripped my Evo 300 factory 2012 down for what I thought was a top end rattle, however found I have a lot of play in the big end on the Conrod. 

Struggling to find a Conrod kit for the bike, does any one know if there are alternatives (i.e pro x kit that fits the beta 300rr enduro) or similar. 

New Conrod from Beta is £190, am I correct in assuming the crankpin won't be worn, only the Conrod?

Many thanks

There is no reason to assume that the big end pin will be OK to reuse after a motor suffers a failed big end bearing.

When the crankshaft has been pushed apart, the pin can be inspected for damage.

When I bought a con rod kit for a Beta 125, it came with the big end pin.  Don't they all?  It is basically the inner bearing race.  (unless I'm confusing termonology)  Beta USA told me people were just buying complete cranks.  IIRC, the price was about double but you did not to pay someone for the crank building work.  The 125 crank was a little tiny thing with lots of plastic for filling volume.  It looked like you needed some specilized fixturing to support it in the press.  It was not mine so I took it to a specilized shop.  The guy who did the work did not want to tell me or show me how he supported of held it.

Connecting rod comes as a kit. But it is 400 dollars more for a complete  crank.
