I know you guys are probably tired of hearing about my 9U D6 and it's troubles. Sorry, but here goes some more.

I got the rh side all put back together and decided (on advice given here) to check the bearing adjustment, etc on the lh sprocket. It was good advice....

Bearings were pretty tight, I thought I would tighten it up a little more if I could, it only moved one notch on the spanner. That was good. 😊

But.........the bearing housing/trackframe holes are all out of line on that side too! 😞

Only 1 broken bolt, other 3 bolts and both pins in place. After cleaning all the dirt & stuff out of it, found the front pin mashed down, only 1/4" or so sticking outa the frame, bottom of housing is all wallered out on that pin hole, pin is 1/3 out of line with the "good" part of the hole. Rear bolt broken off, front bolt is loose, frame had a hole cut in it on the side and a nut put on, that bolt hole is all wallered out.

Rear bolts and pin in place but pushed to extreme rear of holes in housing, even wallered into the holes a bit.

Then I find the best one of all. The bearing housing/mount is broken all the way through from the bronze bushing bore out to the outside. No way it can be salvaged. I guess I'll be checking the area salvage yards.....😞

I did get the front pin knocked out of the frame.

Thanks for listening - dd

Hi DD,
seems like someone has been charging with the blade tips at stumps or rocks to amass that sort of carnage!. All you can do is keep on fixing the next most obvious problem until you are satisfied with the outcome at the time.
Most logging machines I have encountered seem to have recieved 1 life times of servicing for each 4 life times of work, followed next by quarry units.
The good operators book does say it is the operators duty to go over the machine each day looking for loose bolts, cracks etc. etc. If only!
Good luck with it, persistance will win out in the end.
Cheers
Eddie B.

DD, we are not getting bored, just learning more. post a picture of the broken piece. most likely it can be welded.

Dirt Dog, do you remember irnsrgn from SFT?

His sig line goes like this - Knowledge must be shared or it lies dead in the mind.

I would say that these guys here do not mind sharing their knowledge.

I would also say that each problem posted here not only allows them to share their knowledge, it can also result in everyone possbilly learning about something that they were unware of.

Now, pictures are worth at least a thousand words and most likely, a whole lot more. Put a picture of the wounded part on here, and let's see if others think it can be saved.

I do remember seeing that quote - thanks

Kinda interesting King - my ole Catskinner buddy here told me the same thing you did, weld it, he said he has done many of 'em.

I might consider that, but have a call in to a yard on a housing. We'll see what they find.

Here are some pictures. Sorry the first pic is so dark, I don't have everything figured out on this camera yet....

DD,
Pleased to hear that you are making headway on your 9U, I'm just on the home straight of restoring my 9U 1447 (194😎. It was also used as a logging tractor, although luckily I haven't experienced any of your problems in track frame alignment.
So far, I have fitted a new cylinder head, valves, gasket, liner O rings, replacement piston, new piston rings, con rod bearings, donkey fly wheel bearing, replacement bottom rollers, sprocket bellow's seals, repaired the broken equaliser spring, had my crankcase guards stolen!, fitted drawbar quadrant brackets and fitted replacement fenders, radiator side guards, track guards, floor plates.
Some days you seem to take 1 step forwards and 3 backwards, but you will get there in the end!

DD, that is not a big WOW for repairing. clean it up and take it to a good welding friend.

I don't like to patch stuff unless I have to. I doubt there is any shortage of good housings available.

King, I have 3 welding machines.........

I can only imagine what my better half would say if I told her that I was having to take something to get it welded, 'specially after I bought this last machine....... 🙄

I'm really not afraid to V it out and weld it, + there is room for a strap on the bottom. I am confident that I can repair the crack where it won't cause anymore problems.

What bothers me is how bad the holes are egged out. It will be hard to get everything tight again where it won't move with those holes like they are. I will try to get a pic of it.

I know that you would fix it King, but with your location, you probably don't have a lot of choice. If I can find a good housing close by and reasonable, that is what I am going to do.

And.......if I can't? I'll start welding on it..........😎

Thanks - dd

ok DD, just make sure the piece is good and clean and warmed up when you weld it with a good rod.the mig won't give you the penatration you will need. the best part of this piece is you can see it when you get on and off the cat. so if the welds don't hold you will be able to see it before a problem occurrs.

you did say it was cast???? but it can't be cast because i just welded mine on THE HOOD. but i find that caterpillar steel can be welded with a good 7018 rod.
