Maybe someone can help here; I'm stuck trying to remove the skid from a '00 MM 700 141". The right side hanger that attaches the skid to the tunnel right near the end of the rear skid shock at the back of the machine is giving me trouble. The main 14mm bolt that bolts onto the hanger goes into a big boogie wheel just won't come out. The left side came out easily. But the right one just spins the axle assembly i guess. I tried putting the bolt back in the left side and tighten it down then holding it start backing the right bolt out. Instead it just keeps pulling the left bolt out. Any idea how i get this right bolt out?

Apparently the previous owner of this sled had problems with that right hanger and ended up riveting it in place instead of it being bolted to the tunnel. So need to get this bolt out so I don't have to drill the rivets to remove the skid. I'm also not sure i'd be able to get the skid out with that hanger attached anyways (it might spin around to the down position and allow me to pull it not sure) Camera charger is nowhere to be found or i'd post pics.

Thanks for your help!
 
another trick is to slide the open end of a 12mm wrench between the bolt and the tunnel and tighten the bolt down, then try loosening the opposite side.

if that doesnt help, there should be enough room to get a vise grip or narrow pipe wrench between the bogie and the tunnel to lock on and keep the axle from spinning. be sure and smooth out the axle before reinstalling if you get any teeth marks on it.
 
Well i don't have a working air compressor for my air tools; so i'll have to give the 2nd options a try. I'll get a another hand out there to help me with it today and see if we can't bust it loose. If it won't budge i'll just drill those rivets and go from there. Thanks for the advice.
 
my sled does the same thing must have been cross threaded an some point tighten other side reomve the trouble side then try the other side with the impact only way to solve it is to change the cross shaft
 
I'm not happy with how the previous owner attached the hanger there anyways. 3 small rivets and a tiny bolt thru umhw then thru the tunnel and hanger. Take a good hard drop and i figure that hanger could snap those rivets pretty easily. 15+ miles in the Alaskan back country with your tunnel collapsed on the track on one side would not be a fun situation.

Figure if i drill the rivets i can come back later and put bolts and washers thru there and provide a more rigid strong fix. I'm not the most mechanically inclined person out there; but does this sound like a good solution? This sled is currently just a parts sled for my other 2 MM's. Eventually I want to completely rebuild it as it's got a solid engine in it. But for now i need parts from the skid assembly for another sled.

The side that comes out easy. Put a nut on that bolt and thread it down close to all the way. Use it as a locknut. Put it back in and tighten locknut. Remove the stuborn bolt and then loosen locknut and the easy bolt. Voila
 
Still working on this issue. I'm getting a buddy to bring over an Impact Wrench to try and get that bolt out in the morning. I have no experience with air tools at all so this should be interesting.

I do have another question though. I'm pulling the skid to remove a working front skid shock. I have an existing sled that has the shock already removed with the skid still installed that I want to put it into. (The top of the shock collar just snapped right off and I was just able to unbolt the bottom and pull the remnants out) Is it possible to install this shock with the skid still in the sled. If so any tips or tricks? Lastly will I need a spring compressor tool for this job? Hope the shock fits; trying to take one from a 2000 MM 700 and install it in a 97 MM 700.

Any insight b4 I start diving into this in the morning would be GREATLY appreciated!
 
yes

it is a little monkeying around, but unless there is other reasons you should not have to remove the whole skid. you need a way to support the back of the machine to weight and unweight it. I use a nylon ratchet strap I have hooked to the ceiling. unweight the sled a little. you may have to remove tension from the track by loosening the rear axel. you should be able to get out the front shock. you may have to use a nylon ratche stap, and maybe a friend to hel you get in and compress the new shock. bloody knuckles and some cussing and you should be done. P.S. if any of these bolts are rusted shut this becomes a more interesting project. angle grinder or better yet a dremmel too with cutoff wheels are your friend. :2strokes:
 
It turned out to be pretty easy; The bolt came out super easy with the proper tools. Then we compressed the shock used bailing wire to keep it nice and short. Unbolted shock. Flipped the other sled on it's side. Secured shock with 1 bolt. Flipped it back on it's track. Put some weight on it till everything lined up. 2nd Bolt in. Cut bailing wire and done. Thanks for all the help!
