doing a bottom end rebuild on scrambler 400 and was wondering how to get the gear off the counterbalance to replace the big bearing. I don't have a press so I was wondering how you guys take it apart, and if I can do it with hand tools?

 

First off you have to have the puller to remove the counter balancer from the engine or make one like this poster did. https://atvconnection.com/forums/pol...ce-puller.html One place to check on the puller is here also.Polaris
The gear has to be pressed off with a good press to get to the bearing. Or once the counter balancer is out you can send it in to have it rebuilt.
