A crappy 2 minute whiney video :D. I suspect it is normal for an older machine with an enclosed cab to reverberate every vibration. I think down the track I will attempt to add some sound proofing to the cab.

have an 84 model d with a direct injection motor. I replaced that precleaner with a TurboII, which does not have a glass or plastic outside bowl to break. my brakes act like yours too, have never figured out why they are so grabby sometimes. really love this old tractor, it had a really tough life before I got it but is in pretty good shape now.

Yes I have seen those precleaners used before. May get one down the track a bit maybe.

Now I remember why I bought an air cab. Two hours of that was enough.

who uses brake to stop dozer what is the blade for, very little wear there always have hand on lever and replaceable edge with out pulling tank and steering top.
Depends what you are doing , sometimes its not practical to use the blade to stop the machine. Thats why they put brakes on them.

So the next question in this seemingly unending saga, is how hard is it to remove the track frame with the blade still attached?
The story is the front idler had about an inch of vertical travel in it. Feeling with my finger found the retaining strips on the two inner collars were gone. I broke the track and removed the idler and the wear into the track frame needs welding up and two new triangular strips welding in.

It would be far easier to do this welding in the flat horizontal position which means removing the track frame. I have the lifting gear to remove it just the blade is still attached as I was not planning on removing the track frame. Of course I could just put in some weld there as is and do a proper fix of both sides down the track as sure as eggs the other side will be worn just as much.

Blade will have to come off to pull the track frame. Are you saying the rails that the horse collars ride against are gone?
What I have done in the way back past on D8s was to push down on the blade and raise the track track frame up and then stick come blocking under the rollers so it stays up in the air and you can work on it safely.

While I'm thinking about it, is the plate with the bumps that the springs ride on still in place? I've seen those plates go missing and watched the idlers jump up and down just traveling over flat ground.

The rails are still there, just worn. I have got the welder out and the wear looks worse then what it is. A single bead nearly bought it back to original height. And that was welding vertical.

The springs and plate is stell there. I have ordered new springs though, as they are cheap and one side of the yoke has no spring left in it,( it is touching the retaining plate).

Used the plasma cutter (45 amp one) with gouging tips to gouge off the old retainers. I ended up removing the yoke as well. As expected, one 3/8 bolt snapped off. Should not be too hard to extract it now it is easy to get to.

Makes me wonder if I should put new seals in the track adjuster since I have it apart this much. I ordered new retaining strips from Cat, but their freight times have gone to crap. They are telling me six days to move these parts 600km from the warehouse to the local dealer. I remember when a lot of stuff was overnight.

The new strips turned up and I have welded them in. They came with a wide strip of hardfacing on the bottom.

I have machined up the collar so it is flat on the bottom, did a test install and worked out what size wear strip to weld onto them. All there is left to do now is put it back together. I also found out the previous people who pulled the idlers off last time had a bet each way whether to put them in the high or low position. As this was was inthe low position and the one on the other side is the high position. So I have break the track, pull the other idler off and spin it around. Not happy Jan.


Air con got regassed on the weekend. Gets down to 7C now.

I agree 100% ,was taught that years ago.In my opinion resting your foot on the brake pedal is a bad habit,but it’s not my machine

Got the other idler off. The bolts had been snapped off on the other side, hence why they put it in the high position rather then get the bolts out.

I ended up having to mill the bolts out. Got the tracks back on OK. This dingo sure has a million uses.20200521_145103(0).jpg

Stickrake has arrived. I am happy with the quality of the build, it is not as good as a Homan or Gessner (it also did not have their price tag) but for what I am going to be doing it will be adequate. It was not designed for this blade but it is going to fit it very well. Been doing other stuff. Replaced the ball joints to reduce the sideways movement of the blade. Have got covers for the track frames. I have borrowed a gauge to pressure test the steering system.

Stick rake is connected to the blade and seems to work quite well. Is rather heavy so I try to keep it on the ground as much as possible.

Gave it a test run this afternoon, and now I have broken the connector that joins the push arm to the blade trunnion. It is apparent this is not the first time it has broken there. Some person who had ten seconds experience in welding tried to weld it back together some time back.

I have fully replaced the ball joints in the centre of the blade to remove some of the sideways slop.

Looks to be well built.
I guess it’s better to have it a little on the heavy side rather than too light.
Best part is raking with a cab.
I still can’t get used to being allowed in the house after a days raking.
In days gone by I was usually forced to have a bath on the lawn under a garden hose.:(

Talking about dust... I just picked this compressor up yesterday to blow gear down with.
They are used machines, this one has done 2000hrs, refurbished from Japan, and look brand new.
It replaces an old VW unit that we’ve had for years... the ones that run on two cylinders and blow on the other two.
