@MattA
Harry has one with the multi hole adjustment , but said there is not enough adjustment .
This was an option I considered before going with the uhmw guides .

Dave - This is the adjustment mechanism. It moves the shaft. The adjustment is done by loosening the nuts holding the shaft bearing and then adjusting the tension on the adjuster and tightening it all back up. The top bearing bolt passes through the square hole in C29788.

#3 is C29877 - Appears to be NLA :headbash:
#5 is 129-163 3/8-24 lock nut

Guys, this thread has been very informative, thank you all for your input.

@MattA I think part can be easily fabricated out of a similar size bolt. Probably more difficult to fabricate the bracket that holds the bearing in place.

Easy build :smash: Cut the head off a bolt or use a piece of allthread, and weld on a large diameter fender washer :69: And maybe a little grinding.

If you look up "square hole washer" you will find many. Get one of those and weld it to some thread.

Looks like part C29877 gets connected to the square bracket for the jackshaft bearing, number 29 in the parts manual. There are two square holes on the bracket and I think C29877 fits with the upper square hole. I thought the bracket was more complicated, but it doesn't seem so at all. This would be a pretty simple modification. But it's adjustable only one one side? That skews the jackshaft somewhat, right?

Eugene, the sb48 does not have part 29. They only have 2 holes for the bearing flange on the housing. The bottom hole is fixed and top hole is slotted along with the hole for the bearing and flange. So you just have the 2 flanges, bearing, with the driveshaft. Then weld on a tab with hole on the back of the caster and and you have your chain adjuster. I have a spare c29877 that I don't need. Measurements are center of square hole to end of 3/8-24 threads is 2 1/2" if you want to make your own.Image

Eugen - My SB48 snowcaster also does not have part 29. The shaft bearing is held between two flanges. The bearing and adjustment screw are held in place by a pair of carriage bolts.

The best part that has come from this last part of the thread is there seams to be at least 4 ways to address slack in the chain . Multi-hole sprocket adjustment . Threaded rod / slotted housing . Idler sprocket . Uhmw plastic guides . Each has there own advantages and disadvantages depending on your situation . A good chain and proper tension will help the auger sprocket last a long time . Thats not an easy one to change . All the other parts are disposable in the grand scheme .

Eugen - The manual I am looking at is 8-3073. Snowcasters start on page 26.
