Ed's 77 Terex 72-41 Wheel Loader

I think the two holes are not for fine adjustment, they are to keep the plate on.

Could very well be, looks like a high torque loading pin.

Yeah, it’s what the machine articulates on in the middle.

Got both front wheels off, digging in with the bucket broke them loose. I left two bolts on each to keep things under control. With the tripod set away from the wheel, it just pulled the one leg closer to the wheel. So I would pull the third leg back, and the wheel would come with it. Had to repeat a few times. Two of us were able to lift the planetary housing off, but not the drum and hub assembly. Too heavy, used the tripod for that too. Plus it kept from dragging the hub over the spindle threads, did not even touch it.

The brakes before cleaning, the inside of the wheel cylinders were pretty nasty. Two wheel cylinders honed good, the other two were too pitted. Already replaced with new ones that came with the machine. One of the springs that keeps the adjuster in place was broken and brazed too, otherwise all is good. I found a place that has the adjuster spring already, have not ordered yet though.

A shot of the drum/hub assembly hanging from the tripod. After setting it down, we rolled it out of the way.

First is a pic of the drive flange installed, I think that is what they call it. You can also see the pins we made to make installing the planetary housing easier, they are pointed. We got one planetary hole on there, and it held the weight while we got the other holes and planetary gears aligned.

Second is a pic showing the torque wrench, had to make a spindle nut socket, it was not available anymore. Welded an 1-5/16” socket to a plate with pins in it. It calls for 600 ft lbs, then set to 25 lbs rolling torque. Rolling torque was already there at 600 ft lbs, had to use the 9 foot cheater pipe to get the torque.

Third is the planetary housing before cleaning it, we put everything back together clean. I am told planetaries are used to handle the torque better.

Here is the spindle nut tool. Not pretty, but it worked!

:thumbsup: I am enjoying your thread and good pictures. I have worked on a lot of machines, but never one that large.

Thanks for the comment. I was hoping by posting this I would get help from people with direct experience with this machine. There does not seem to be much direct experience out there, but it is still a good exchange of information.
