Shaker board bearing help

[highball]

Hey guys, last week I had to change a shaker board bearing. It was extremely hard to get off and get the new one on. Literally sat there for ever with a rubber mallet. This week I am having to change another, same issue, although this time, I have managed to mess up the bearing (no real surprise there). This there something I am missing? A specialTool for this, or technique? Any advice would greatly help.

You need a press. It needs to be big enough to handle the shaker shaft. Try Harbor Freight. They are possibly the least expensive.

Brunswick sells a driver made especially for it, listed in the tool section of their parts books

working with a steel hammer will make the job go a lot easier and quicker than using a rubber mallot. I use a big long tapered punch to punch the old one off the shaft. punch it from the inner bearing ring (use safety glasses). Then to get the new one on I believe one of the hollow bearing drivers from the Brunswick mechanic brass punch and set is used for this application.

I use a good sized 2 jaw puller and pull the bearing assy off that way. I've done the hammer thing and after ruining a number of bearings from miss hits and dinging the shaft, I figured there must be a better way. Not to mention smashing my hands.

To install, get a piece of fence pipe the same diameter as the inner ring of the bearing and drive it on with a small sledge hammer or mallet.

I have also seen in my experience with these things that if you wail on the inner ring too much, it will fracture. Seen alot become that way so be sure to check the inside of the inner race to be sure it's not cracked. I have only found this out AFTER I THOROUGHLY CLEANED THE BEARING and inspected it.

To remove the main shaft bearing (the shaker board does not use any bearings ) I use my vise. Place the shaft in the vise but leave it just slightly loose. Use the vise and shaft like a slide hammer. Slide the shaft hard until the bearing strikes the vise. The impact will pull the bearing off the shaft. Two or three pulls usually does the trick but sometimes it takes more.

To install the bearing, I use a 1 1/2 inch by 6 inch threaded galvanized pipe. The pipe is softer than the bearing so it should not hurt the inner race. The trick to installing any bearing is to be sure you use the race to drive the bearing on that you are pressing against. Do not use an outer race to press an inner race onto a shaft. This will destroy the bearing while installing.

Hope this helps...
