Touch control pump

[jastusa]

hi team,

I’m rebuilding the pump, following instructions in this site, and when I split the pump the brass bushings have not released as expected, meaning I cannot get to the internals. Any idea how to get the brass bushing out (see picture) with damaging anything? Cheers, Jason

Have you been using this HOW TO post? It explains it pretty well.

If you still have problems, let us know...some will give you more help! Good luck.

Thanks Dale. Yes, that is the link I am following. The early step is to separate the cover plate form the main housing, and when doing so, the brass bushing has not come out as expected, hence the post. I suspect the internal gear may have some corrosion, as the shaft is difficult to rotate. Corrosion or a build up of something has caused the bushing to stick, and there seems to be no pry points that I can use. I don’t want to grab it with multi-grips as I’m wary of damaging. Perhaps I need to simple pull the shaft with force? Cheers, Jason

Hi,
Below is Cub Touch Control info, if you need it.

When you put the pump together, and are putting on the drive gear, the lock washer holding the nut on at the pump gear has to be good, to keep the nut from coming off during use. It bends over 1 flat of the nut. You have to bend the lock washer away from the nut to remove the nut, which I guess you did.
Then bend it over 1 flat of the nut when putting the nut on again.
If the lock washer is still good, you can use it again.
It has to have the little tab that goes into the keyway, to prevent the nut from turning. Sometimes the tab breaks off, some people on here have said. If the tab is broken it needs a new lock washer.

Below is a listing for the lock washer at TM Tractor, the pics show the tab on the lock washer, you can look at the pics.

The pump shaft where the o ring runs has to be flat and in good condition. Sometimes the shaft wears, and there is a groove. If there is a groove, it needs repair. It may need smoothing with fine sandpaper.

Use plenty of clean Hy-Tran fluid when putting the pump together.

Below is a post I made about checking or changing the Touch Control fluid, filling the system, and removing the air.
Be sure to read the 3rd page of the links I posted there.

Well, got it sorted. Ended up holding the shaft with a rag by hand so I could get a good grip and gentle tapped around the housing with a small hammer; came apart in time. Polished up and will commence rebuild tomorrow, going for clear coat option. Thanks all.
*haven’t heard of hytran fluid before, will see what we have that is comparable in Australia

Not sure how hydraulic fluids are labeled/rated in Australia, but any MS1207 or MS1209 fluid would be compatible.
