Rayco Super Jr 1625 Axle Removal

Recommended Posts

Thanks. Had plenty of heat and my 4' stilsons on it and it still won't turn. Didn't really want to cut it off as I need a fairly accurate shaft to copy when I make the new one. Doesn't look like I've much choice :/ cheers for all your help anyway.

For those that are interested, a bit of an update........

 

The collars in my picture do turn. They turn anti-clockwise as you look at the outboard ie if you were stood in the middle of the axle. Drift them round by about 1/4 turn, then they move on the shaft, which should hammer out. I had to penetrate the collars for about 2 days before they shifted but once they were moving they werent too bad. The shaft comes out easy either side, I found the best way was to use an air hammer. The vibrations seemed better than big whacks with a sledge.

 

Hope this helps someone in the future if you're ever unlucky enough to do this job!!!

Glad to hear that you have managed to remove the axle. I will bare that in mind if i ever have to remove mine. why did you have to remove it, had the bearings gone??

No, the axle sheared just inboard of the wheel bearing so I had to get it out to machine the new bits.

 

I was speaking to someone today who knows about these things and he reckoned that the over-centre bearings were such a pain in the arse they were only fitted for a short while on the earlier machines. I've come across them on machines I normally work on, but never on a axle bearing wallowing in mud.

I do a lot of short runs of custom machining. Mainly for bikes and 'pimp my ride' type cars, but I do a fair bit for engineering purposes as well. My background is engineering but I had a 10 year-ish stint in Arb so I have contacts who get me to repair / machine parts for their broken stuff. Always happy to take stuff on.

we use eccentric collar bearings all the time on our machines at work. They will lock much tighter to a stock bar than what a grub screw type bearing does. You can lock the collar either rotation to the bearing, it is best to rotate to lock in direction so it self tightens.
