Good afternoon, A few years back I purchased this HD5B and had it hauled to my property in Southwest Missouri. First off, I am mechanically inclined, but did not know anything about Dozers or track loaders, before I purchased this. I just wanted to use it on the weekends to haul gravel, push trees and brush, around on my farm. Anyway I invested in a radiator rebuild, check the fluids, and ended up using it last year the most, about 30-40 machine hours I've used it, so far. So I took it out in the pasture a few weekends ago to push brush around. I wasn't turning sharp, going back and forth navigating some roots in the ground, and the left track jumped off the front by the bucket, in towards the radiator. It is sitting out in the field a couple hundred yards from my barn, and I've prepped the area to get a 12 ton air jack and compressor and started to try to jack it up in order to try to move the track on. I realize I'll need to loosen the adjuster and move the idler back, not sure if in reality I'm equipped to do this, and since I've never done it before. I have several reprinted manuals (operating, parts, Service manual), and what seems to be the original repair parts manual for this machine. From the beginning I noticed on both sides the tracks are very worn (and have rebar welded on them), sprockets and Idlers and other surfaces are welded on, I'm assuming to increase the adjustment life of the tracks without replacing expensive parts. Also many guards and parts seem to be from other machines (painted yellow in some cases). Lastly, lately I noticed the tracks were sagging but I haven't adjusted the tracks or greased the truck wheels or sprockets in any way since I bought it...the manual says to use a "special grease gun fitting" to do this or you will blow the seals out using a high pressure grease gun. Probably ignorant, but I was more scared of ruining something that greasing them considering I wasn't using the machine that much. Also, the threaded rod to adjust the tracks is very rusted and I'm not sure if I can break them loose, or even have a wrench to do it. So I'm looking for any experienced advice, 1. how you would approach getting the left track back on to drive it back to the barn what tools I need to have or buy to adjust the tracks 2. about putting grease into the wheel bearings, etc. And from looking at these pictures, as to what I may be dealing with in terms of "looks ok to use if you can adjust the tracks", or "the tracks and related parts are worn out and should be replaced", etc. Also note the pictures are over time, so the tracks are pretty well adjusted in some pictures, and sag over time.   I realize this is a lot of information, any advice you may have is greatly appreciated! Thanks, Andy G.

You don't need a jack - you have loader - tilt bucket down onto blocking so cutting edge doesn't go into ground - then lower loader arms to lift front of machine / next place blocking under track about 1/2 distance back - lower machine by raising bucket - machine will tip forward - block back of machine, under drawbar, with heavy blocks thaw ill not sink . Now power down loader arms and raise front of machine - remove the block from under track - block front of machine now for safety and track is free . Lubrication for track rollers is a simi-fluid or heavy oil - not grease and is pumped into opening in rollers as free flowing and allowed to come out around tube used to pump it in . Yes you need to back off the adjuster and move idler back to get track over the wheel. Heat and big wrench , pipe wrench or other means of levering the adjuster . I made a wrench from 1/2 steel plate cut to fit over adjuster , then it has 2 - 1" rods welded to it so i could slip heavy pipe over rod to apply leverage = the 1" rods were welded about 45deg from each other so when turning it you had new point of leverage ------------- Faith isn't a jump in the dark.

Welding rebar on track is a good way to increase pad life - but when done properly at least 2 bars should be welded to each pad - fwd and rear part of pad ------------- Faith isn't a jump in the dark.

Coke, thanks so much for the information. I'll try to block it that way next weekend, and see if I can get the adjusters to move. What weight oils do you use for the rollers, 80 or 100 weight or more? Would running through a plastic tube using gravity work, or what kind of pump to use? Again, thanks. Andy G. |
