Rear roller support bracket

[8270king]

I had a rear roller support go out. It was cracked. My method is to bolt the new one over the top of the old with 1/4x20x1" and stover locks.

I repaired one this way a year ago and still holding strong.

No reason to grind or chisel the old one off.

I agree. I just chisel off the remainder of the part that actually holds the bearing. On a related topic, has anyone tried the rear roller repair kit (for when the shaft gets cut off)? I recently saw this in the 82-90 parts manual. Does it work well, and is it easy to install on the stub? Just curious.

Pit,

I do not chise anything off......I pound it back into place and bolt the new one over the top. Time saver.

Pit,
I keep two in stock, just because you never know when you'll need it. If a roller snaps off, you throw your spare in, take the busted one out, stick it in a corner, forget to order a new one: then six months from now another one brakes and you say OH CHET. If you got that repair kit on the shelve your saved.

The kit comes with one steel pin that is inserted into the shaft to hold it together. I drill a second hole, 90 degrees away from the first hole and insert a roll pin. You have to grind the pins down so the bearing will slide over the pins. The drill bit comes with the kit. There is a special size bearing that also comes with the kit. I found that the one pin is not enough. There is to much stress on that point of the shaft and it causes the hole in the shaft to wear out prematurely,causing the steel to pin to work its way out.

I have one thats been in a machine for three years. So I think there ok. There great if you get in a jam.

I also install the new bracket over the old one. Just bang it down, knock off any sharp points, and use washers to keep the bracket flush with the side plate, only use the washers if you need them. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

Gents: Im a man with many dimensions including the tire around the ol waist but if you were to put a new retainer on ontop of the old retainer how do you make sure its a flush fit ot the dimentions are correct.

Cracked rear roller retainer. Shut down the pair plus the odd or even next to the mechine that i need to repair. Pull the pit and prepare. Grab the fire extinguisher, hand grinder, 3/16"-1/4" drill bit and dill, and a good pair of vise grips. Drill holes through kickback. Pull pin on extinguisher. Grind away, until all of the original retaining ring is gone, watching for any signs of fire. After kickback is flush take a smoke break while waiting for the kickback to cool. Next take the 90's spacer and apply with new retaining ring. Bolt on with lock washers and wala...good as new.

Fire Extinguisher you ask?!?! Well it hasn't it hasnt happened yet but we sure came close to a mini blaze. An Ember almost cought fire on some debris. Now why use a hand grinder and take that chance? I believe that it works better and I personally get better results doing it this way then chisieling away at metal. Plus who has that kind of time...

Stahl's sells a rear roller that has replaceable shafts. I won't buy anything else. The shafts have a thick flange & bolt on with socket screws.

As far as the retainer goes, I just use a Dremel to cut off the protruding, broken portion. Then use a grinder to smooth it out. Drill 5/16 holes, using the original bracket for the template & bolt the new one on. It takes about 15 min.

Deadwood,
If you have pulled the pit completely and cleaned it why would there be debris to catch fire?
I agree with just chisling the old off and smoothing up with the good old Makita. Use the old as a template and drill and mount. Come back in a month or so and check bolts for tightness though. Never have used the roller repair kit, but do have one handy just in case. Never ever use the light weight rollers manufactured by a certain company.
