Tonight I pulled the left side track off the crawler and have a few questions on the that side . After I got the track off from under the track frame , I check to see how much slop was in the idler bushings . The bushings have a little slop but the right idler bracket can be lifted about an 1/8" . the left idler bracket does not seem to have any slop in it .
Are there shims available to correct this or do I need to wait until I take it apart to see if the guide and adjuster bracket are worn ?
The rivets on one of my side frame to crossmember brackets are loose and the service parts manual shows rivets to replace the them . How is this repaired today . Grade 8 bolts and Loctite ? they appear to be 3/8" rivets now , I remember reading a thread about it but can not locate it . Since I have to swap the tracks end for end to get the pads pointed in the right direction I would like to fix this before something else gets broken because of the loose rivets .
The mating surface between the steering clutch housing and the transmission is leaking oil so it looks like the transmission seals (both sides) are shot and they will be coming off to replace them .
Any suggestions will be gladly accepted . Night all for tomorrow is another day in the ditch Dan

Lavoy I was looking at the holes that the rivets are in yesterday and they look to be oblonged out . So it will be the bolt and weld method of repair on them . Might make an additional plate for the inside to help spread the load more effectively .
I was puttering yesterday on the crawler while waiting on a friend to show up and discovered that the wiring harness behind the panel was Fried . No wonder the battery would not hold a charge ! Removed the whole harness and will be building a new one . Once that was done I decided to take the instrument panel housing of to remove several broken off bolts . I managed to get everything but the rollpin in the throttle lever out without breaking anymore bolts or snapping anything important in two . The roll pin has probably been in there since the crawler was new and will not budge , short of taking the O/A torch to it and heating the base of the lever red hot and then trying to drive the pin out is there anything I can try short of this as the lever is still in one piece . It looks as if the pin is a hardened one and would just eat up drills . I thought I might be missing the obvious answer to this problem . I am planning on blasting all the parts and repainting them as I go here while I am acquiring money to do the final drive and steering clutch rebuilds . Dan

Lavoy , got the roll pin out of the throttle lever after heating it and driving it out from the other side . Now on to the lever itself . I am going to build a puller to pull it tonight as it is raining outside right now . Dan

If you have the hood off, you can push the throttle lever shaft backwards and get the throttle lever away from the dash a little bit. Hold it from going back forward with a Vise-grip against the throttle bracket. Now you should be able to get some heat onto the hidden portion of the throttle lever and that should free it up.

Lavoy I have the hood off the crawler and have the shaft wedged forward , I was planning on building a puller tonight but I am stuck in front of the computer wet nursing a friend on the web through putting in a water heater on another board , it is slow but he is getting there his last post he was ready to hook up the power and turn it on . Luckily he is a certified electrician
So while I was waiting for his posts I read through "Show & Tell" in one of the threads Bill Watson was going to weld in "new" metal into his track frames where the idler brackets mount . He was going to use 4140 steel to do this , I have a pile of 1018 and was wondering if it would be usable to replace both sides of the track frame that has gone south on me . I am a certified welder for pipe so getting it welded in would not be a problem .
It is getting to the point of pulling the engine and center frame while I have it this far down to free the clutch shaft from the brake cross shaft . It never ends right now . But it will be worth fixing what I find before having to fix it in the woods . Dan

I will have to get the idler wheel off and the blade off of it before making a decision on how to rebuild it but from what it looks like , the flanges thickness is too thin to take a build up .
I have to repair the pin holes in the blade control handle as the pins have egg shaped the holes . I am heading out to the shop to see if the it is cast iron or cast steel . That will determine which process I will use to repair the holes .
Thanks , Dan

Hi: Id be interested in hearing what your planning to do to reduce the slop. I chose to use brass bushings and epoxy-steel, but I considered brazing in the bushings. Thanks, Paul
