Super lift arm support strap!

squatch · #1 12-14-2010, 10:01 PM

It seems I'm not the only one who has had some bad luck with the implement lift arm on the supers. I had a run in last winter with an immovable object and my Haban plow. Snapped the arm right off the rock shaft. Seems Cub had a fix for this but as usual I found out after the OOPS! The fix is Cub part# 14297 "cross shaft support strap". You need that and a 1/2" bolt.

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!

Cool...I bet I can make one of those in about 10 minutes and save myself whatever $$$ CC wants for it. I have a spare rockshaft for my 1872 but I'd rather not use it if possible.

thank you very much for posting the pictures. I had looked at my rockshaft and the pin was tilted back being that it was supported on one side but not on the other were the hair pin is. So to support the end of the pin I took two plates one half inch thick and cut the middle one shorter so I could add my implement lift arm. Basically I am sandwiching the lift arm with the stock rockshaft and a plate with a plate in between to keep the lift arm from binding. I no longer use the hairpin but use the same bolt hole that the factory support uses. But I must say I will make one like the factory sells and make it twice as strong.

Thanks for some great pictures! I got up close and personal with my rockshaft and rollpins last night. Heading to the garage shortly to put it all back together. I will be making that strap soon.

Glad I could help. It wouldn't be a big deal to make after seeing one. It is thick. I didn't measure but it looks like 5/16" thick flat stock. Price wasn't too bad by Cub prices. Around $25 at a not so cheap dealer.

Can someone give the measurements for the cross shaft support/strap or if someone has an extra one they want to sell? They went NLA.

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.
