Hyd. Pump wear sleeve install - I think I messed up

RTR · Aug 2, 2015

I just installed a wear sleeve for the first time and at first it didn't want to go in the shaft. I tapped it again and it went on a little. Made 2 more taps and then it looks like it went on too much. Is there any way to back it up a little without messing it up?

This is for a Farmall Super A hydraulic pump.

Here is a picture. The line you see above the sleeve is not a groove in the shaft but rather a "residue" line that I buffed down. The actual groove is under the wear sleeve but I feel like it is just under the upper edge of the sleeve. I don't want the oil seal riding on that edge.

That's a tough one, Chase. If you could clamp the gear in a soft jaw vice (alum or brass lined jaws), heat the ring gently (propane torch, none too close or long) and pry the sleeve up at 2 or 3 places immediately when warmed it might expand enough to get loose and move. It might take 3 extra hands to do so.

This is why things like this generally get pressed, not driven.

yeah, with this being a relatively small sleeve compared to some I thought that light taps with a small hammer would be fine. Before I knew it 1 light tap made it move too far. It even recommended in the directions that came with the sleeve to do so. I could always take some side cutters and cut it off and install another one, but that would be $22 down the drain.

Looks like room behind it, if you can get something-a bearing seperator maybe,
or make a support behind the flange, you could
probably tap the shaft down a bit, raising the ring.

My question is , how are you going to insert the shaft into the pump housing now with a speedy sleeve. Reaming a bushing in there gets pretty delicate. Also, for a speedy sleeve to work well, the groove in shaft needs to be filled in because that sleeve is so very thin. They don't last long otherwise.

Well the EASY way of installing things like that and also bearings is to make yourself and metal box or pan and put some hy tran in it and warm it up to 180 -200 degrees and place said item that is to be installed with a press fit and let them bath in the warm oil for 10 -15 min. and you use a pair of pliers and quickly remove and just drop them into place , no muss no fuss no foul words spoke . I carry a old deep fryer in my service truck and when out in the field and ya have to install a bearing that needs pressed on a shaft and you have no press just warm them up and they go wright on. Same applys to ware sleeves as back in the days of working on semi's and having to istall the ware rings on the axles all ya had to do was warm them up and with a pair of gloves just put them on , no need for that 35 dollar driver and having all the drivers for all the axles.

Good point Pete. I am still learning about this repair and ended up removing the sleeve because of where it was located. I didn't have another on hand and decided to just try the pump as-is (after I polished the shaft). It only had a very minor groove....and wouldn't even call it a groove. It is all back together with new parts and hope it holds. I have another pump with a bad groove, and will use a speedy sleeve on it, but will have to install that bearing/bushing on the shaft first, because when the sleeve is on, there is no way that part will fit over it. The shaft shouldn't have any trouble fitting in the oil seal.

Thanks for the tip. That is a very good idea.
