Ed's 77 Terex 72-41

If you mean the groove for seal #7

Yes.

 

[mountainguyed67]

Wiper is #6.

Nige, could you mean #6, #8 looks like the bolt. Kind of fuzzy numbers, they both look like 8.

Good spot, I mistook the 6 for an 8.

Hey Ed I really appreciate this post, I just bought my first piece of heavy equipment, a 1972 72-41 Terex. I own a towing company and salvage yard so luckily I found this one with 12 foot forks on it so we can move vehicles around. I have been around rollbacks, race cars, street rods, and stuff like that my whole life but I'm not super familiar with big equipment. can you tell me what fluid you use in your transmission, I believe mine is an Allison 3630? thats one of my biggest issues right now if you could help me out I'd appreciate it.

Also do you have a good source for parts, info, or literature for these machines?

can you tell me what fluid you use in your transmission

I use 15W40. The previous owner suggested it because it’s leaking. I’ve since found it is one of the recommended fluids, but I forget where I saw it.

Also do you have a good source for parts, info, or literature for these machines?

I’ve bought parts from Terex, but they’ve since sold the loader division to Mecalac (888) 632-2522, I haven’t tried to buy anything from them yet. That’s for loader specific stuff, a lot of it is the same as articulated trucks and I get it from Terex. I’ve bought parts from Hulco too (816) 690-4577.

I got parts manual from Sycamore (812) 477-2266. Some manuals are on eBay too.

Thank you so much! Youre saying 15w40 gear oil correct?

 

[mountainguyed67]

15W40 isn’t gear oil, it’s Diesel engine oil.

 

[mountainguyed67]

I got the parts from UPS. The backup rings are missing, even though they’re on the packing list.

 

[mountainguyed67]

I went down to Cat today, the backup rings are ordered and I’m supposed to have them in a day.

 

[mountainguyed67]

Also some Loctite bearing fit or similar when you install the wiper seal #8 would also be a good idea

This?

 

[mountainguyed67]

The loader developed a low power issue last time I used it. What should I check? It barely ran, so I put it away.

 

[Bls repair]

Any symptoms?

 

[mountainguyed67]

Ran rough, and low RPMs. Could shut off and restart, but same problem.

 

[mountainguyed67]

This one also says “Bearing Fit”.

 

[Bls repair]

Assuming filters changed?

 

[mountainguyed67]

Fuel filters changed 2-3 years ago. Oil filter not changed. I have the oil filter, and new fuel filters too.

 

[Bls repair]

I would start with easy stuff first fuel flow from supply pump ,fuel filter ,when you take it off see if it’s full. Check air filter and tubes for blockages.

 

[mountainguyed67]

I haven’t replaced the air filter, I’ll look at it. Thanks.

If it's been three years and it's been sitting without a full tank of fuel or the fuel cap leaks I would try draining off the bottom of the tank IF it has a drain valve and I would just change the fuel filters to rule it out.

If it's been three years and it's been sitting without a full tank

It only sits through the winter, and I fill it before winter sets in. Right now it’s about an inch above the bottom of the screen.
