Super lift arm support strap! - Page 3

Aagitch Did you say something about lifting high?

Someone on here had asked me for pics of the plow a while ago. Here is the only thing I have handy.

I've got my plow painted but haven't got the frame done yet. I used rustolieum rusty metal primer on the whole blade. I used rustoliem flat black on the back of the blade 2 coats. and ez-slide graphite paint on the face. It seems to work better on the blade than the blower. My edge is pretty worn as well. For the time being I flipped it. Extreme motor works sells new edges for these in Stainless steel. Hopefully before next winter I'll have one.

I think my setup may be a bit different, here's a pic showing it. This is actually from the parts diagram for a 451 snowblower, for some reason they don't show the crank arm on the plow diagram.

Mine is home made, but same idea. A slot in the crank fits over the flat's of the end of the rock shaft (maybe I'm calling the wrong thing the rock shaft?). Two cap screws bolt through the shaft end. This shaft end sticks out of the frame by the turning brakes.

Squatch,

Real nice photos, thanks. That's what this forum is all about for me. I have 2 1872s and on one I damaged the rockshaft trying to lift my snowblower. I was looking at it the other day and I can't figure out how to remove the rockshaft without taking almost everything out and pretty much taking the frame apart. Is there an easier way?

Thanks

Thanks squatch,

I found a haban blade last year and had no idea what that strap was for, so of course I didn't put it on and I broke the implement end off my rockshaft just like your pic. I had the end welded back on because I could not get the bell end driven thru the rockshaft no matter how hard i beat on it, the pins came out ok but that thing wasn't budgin'. anyway I had it welded back on the end and now the holes on the support strap are about a half inch off ! I will just drill another hole and hopefully that will work. Wish I had used that strap in the first place! arghh!

Hate to tell you this but that is one of the worst jobs you will encounter with these tractors. Getting out a broken rock shaft. Probably the easiest way is to take a sawall and cut out the center section and install another unit. Make sure you already have the other unit that has been seperated into 2 pieces before you start cutting. I would try to get a used one from one of our sponsers here. In my case I was surprised to find That mine came apart easy. I had put such an impact on the shaft from running my plow into an immovable object at speed that it broke the rust loose between the inner shaf and outer tube. I posted one link above but feel free to go to my profile and look up my old threads. There are a couple that address this broken shaft. I used it as an excuse to take the tractor apart and resto it myself.

Ouch!

The whole assembly in pieces.

The fix.

The strap connects the pin on the right side mower lift arm on the large shaft with the implement lift arm via the drilled hole in the arm. This requires a 1/2" bolt.

Looks like it will add quite a bit of support to the lift arm. The Haban plow and 450 snow blower are a pretty heavy load for this part. Hope this helps keep someone else from having to go replacing the rock shaft. It's not much fun!

I have repaired many of these rock shafts. Its an easy fix, clean the paint off and remove some of the old plug weld and weld it back on. Even if you have to pay someone to weld it it would still be cheaper than $25.00. If you look at it close you will notice that the real problem is the factory got cheap and didn't take the few extra minutes to weld the backside of the plate. A small plug weld is very weak but is plenty strong enough to hold a deck , not the force of a plow snagging something solid. I would suggest to anyone needing to remove their rock shaft for whatever reason to put a good weld pass on the back side of that plate before reinstalling it.

I have been using the cc parts site for over two months pretty frequently and just last week they had a big redo on the entire "Older" model tractors. I actually ordered several parts that they showed available and then was notified that they were NLA. That must have happend quite a few times for them to realise that the site was no longer current and they redid it. Our sponsors above have a lot of good stuff a very reasonable prices so we are not totally lost.
