Balance shaft rebuild?

Post by Joe439 »

Is it possible to rebuild the balance shaft with a new bearing and seal?

I believe BDK can rebuild a balance shaft should it be necessary.

Joe,

See my reply under a previous topic: http://kr-1s.co.uk/forum/viewtopic.php?f=1&t=13790

You could modify "normal" 6303-C3 bearings and you could also perhaps use a 23-47-7 seal with a 0.7mm spacer.

Let us know what you end up doing!

Regards,
James
