I clicked the repair manual link, and i already Have that book.
It has pictures of how it all comes apart with gear puller tools, etc.
the Novak site says it's simple to rebuild, and all that is needed is a small arbor press, snap ring pliers, and a bearing puller.
I have snap ring pliers!
Maybe this is more than I want to get into.
Can I do this? Or should I take it out and get someone else to do the rebuild?
