The Shop Manual tells me to use tool HIJKLMNOP which doesn't help me. Do I need to buy a small version of a standard bearing puller? If so, then I assume there is a shoulder on the back side of the bearing that I can grab and pull?
To replace the bearing, do I just pound a new one in using a socket wrench socket of the same diameter? | | | | | Joined: Nov 2008 Posts: 145 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2008 Posts: 145 | I heard once that if you fill it with grease, then get a bolt that is just small enough to fit in the hole without scraping the sides, and push the bolt in. maybe tapping with a hammer or something. The grease will then get displaced and push the bearing outwards. don't know if it works or not. worth a try.

Hope this helps.

I wasted 2 days on using a pilot bearing pulling that didnt fit the hole.

The pilot bearing was out in less than 10 minutes! Then I screwed-up and installed the new bearing without any grease. I had to beat the daylights out of it to push it in place. I hope I didn't damage the bushing. Doh!  | | |
