Question Terex 72-20

Hi, I have a Terex 72-20 Wheel Loader.

Just got it about a month ago and are using it for logging.


The inlet Hydraulic filter has degraded and I need to find out the part number or what sort of filter I can use.

I also would like to get a workshop manual (at a reasonable price).

If anyone knows where I can get parts etc, has ever worked on one this machines or has any info on them that would be great.

Many thanks
Tony.

Hi Russell,

Thanks for your reply, much appreciated.

There are two filters that go in the Hydraulic tank. The one you have given me the link for is the one on the left. I need the one on the right. It may not even be called a filter, it is completely different to the cartridge filter on the left.

Maybe the one I have is a homemade job?

Hopefully you can see the photo and maybe have some ideas.

Thanks
Tony

That looks like a washable screen, if that is what it is, you may have to go to your Terex dealer for it.

Great thanks. It has inner 1/8 inch steel gauze that seems to be the frame. Thin on the outside it is small brass screen. Calling it a filter rather than a screen is probably where I have been going wrong in terms of trying to find one.

I am in New Zealand and we don't have Terex dealers anymore. Can you recommend somewhere in the US I could call?

Having the right name for it half the job as I have been asking for a filter.

A lot of tractors also use that type of screen on the pump intake side. When it gets dirty enough to clog and get sucked flat, you can count on other issues in the system as well. Worst case, you could cut the end off and reform it on a dowel back to shape, then re solder the end back on. One has to see what kind of debris is in the system that would be so dirty. Metal debris or seal debris from the cylinders? A lot of times it's the inside of the hoses that break down and contaminate the system. What ever it is, it needs the tank and system cleaned. Likely the pump will be weak from wear.

Tony, if Russ is right on the number, the filter is only $27 nzd. No idea as to the $$ for freight. Take the NAPA number and convert it to a brand you have and I trust you'll find it at a store 20km from you. For example over here the NAPA 1136 is also a WIX 51136. https://www.ebay.com/itm/Napa-Gold-P...dYLclr&vxp=mtr

NAPA is a large automotive parts store chain in the us and they don't make anything, just resell it. So if you look at the part numbers we can see that the NAPA filter is made by wix. Look at cross references on the wix number for something you can get locally.

This also translates over here to one made by Hastings. HF743 which means hydraulic filter.

I think your Terex has an Allison transmission, my Case loader does and I think it has a suction screen about like that. Google "Terex dealers" and see what comes up. I'll check my Case parts book in the morning.

Hi, thanks. I see how I was able to convert to a local part number. Very useful. I just need the other filter/screen in the hydraulics. There are two filters and it is the other one that has broken. Rgds Tony
