Ed's 77 Terex 72-41

Not necessarily 2 pumps but 1 pump with another scavenge section and another suction bell in a forward sump connected with a long suction tube back to the combination pump or a similar configuration

Now I wish I got pictures of it.

He says it’s ready to go in.




We have the one green part (blower drive gear) in the middle because the red one had an oil filler integrated into it. There was no room for it, plus it would be under the cab.



Block heater hidden up there.

 

[mountainguyed67]

It warped, and needs to be pressed straight. It’s probably 2 plus inches out end to end.

 

[mountainguyed67]

Got the dipstick tube mounted to the bracket coming off of the oil filler housing.


He didn’t like the wear in the lower pulleys, but didn’t have one like he thought he would.


I taped off anything that was open after he left. Also cleaned up the mess, he left quite a mess. Emery Cloth and greasy shop towels mostly, and scraped off gaskets.

Ed,
If you want to take care of the wear in the pullies fairly cheaply, find someone with a metal lathe and deepen the belt grooves. Take care to keep the original slope of the grooves. It will change the diameter of the pullies a little but it usually doesn't matter.
For anyone really finicky, they might fill the wear up with brass (cast pullies) and re-machine but I have never bothered with this kind of fix.
Your perseverance on this job is downright amazing. My hat is off to you!
Jon.

One of the two rear axle side to side articulation pins has been backed out since I got the loader, I tried to get it back in before and couldn’t. This time we worked above it with the engine gone, it still took about 3 hours. Can’t really get to it, and kept trying different things. It really didn’t want to go in.


Both pins had a mounting plate welded to one end, both were broken off. The other pin they had already welded a plate to keep the pin from coming out the other end.


So I took my son’s 110/220 welder up, and a borrowed generator. Every time I struck an arc it about killed the generator, even when I went from 1/8” to 3/32” rod.


It’s on, but I don’t know if it’ll hold. I guess I need to hit it with a hammer. I’m also considering renting a welder with an engine on it, and just burning through better.

 

[mountainguyed67]

This is the other end of the same pin, a plate hangs on the two locating pins.

 

[mountainguyed67]

The engine can’t bolt properly to the stand anymore, the front and rear mounts are spaced different and the flywheel housing is narrower. Before taking the hoist away yesterday I pushed it to see if it’d go over, like I always do. It did, but the hoist caught it. I couldn’t stop it by hand. I lifted it back up and bolted it down in one corner, I can’t push it over now if I wanted to.

Yes to getting a better weld on the pin retainer.

Ideally what should I be looking to rent, there are various sizes?

 

[Welder Dave]

Probably the smallest you'd find is about 200 amp which would be plenty. You only need about 130 amps for 1/8" 7018. A little preheat on the frame would be a good idea because it's pretty thick. Weld uphill with a weave would be best but grind the existing mess out first. Sorry, can't really call it welding.

 

[mountainguyed67]

Smallest is 140 amp at Home Depot, but none in stock. Sunbelt has a 170. United wants less for 300 amp tow behind than a 189 amp that’d have to be loaded into a truck. Sunbelt prices are less. I won’t be able to preheat. I agree it’s a mess, inconsistent power.

Here are a couple of my welds from when I built a gantry crane six years ago.

 

[Welder Dave]

Even a small propane torch for a few minutes would give some preheat. I didn't think Home Depot rents engine drive welders. If you could rent something like a Miller Bobcat would be ideal.

Come to think of it, my son’s might have one.

The Home Depot machine is AC which isn't as nice but could work for what you need. United Rentals prices look kind of stupid. Are there any other rental places in your area?

My older son has one.
