mowerman Posted October 9 Share Posted October 9 You might want to check Google for your area. There’s a lot of shops around that. Do that.

Joey Mack Posted October 9 Share Posted October 9 can you take it apart and see what it needs? pumps are simple. what is the reason for the pump repair? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74624-power-steering-pump-rebuild/#findComment-559779 Share on other sites More sharing options...
yarnall Posted October 9 Author Share Posted October 9 I called the local hydraulic shop and they don’t rebuild them. It was pumping the oil into the crank case. My father’s rollback was doing the same thing. He bought a new pump for $1000 but thought it would be cheaper to have it rebuilt.

Popular Post mrsmackpaul Posted October 10 Popular Post Share Posted October 10 I have had this happen, just a new seal and a O ring, if I remember correctly It may of been just a dust seal and a hydraulic pressure type of deal No matter, it was pretty simple either way Paul 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74624-power-steering-pump-rebuild/#findComment-559788 Share on other sites More sharing options...

Popular Post Joey Mack Posted October 10 Popular Post Share Posted October 10 Bob, when you take yours apart, look at the sector shaft, and make sure the seal didnt cut a groove into it.. other wise you wil waste time and money, some shops can weld the groove and then turn it back down..

mowerman Posted October 10 Share Posted October 10 You know years ago I was just thinking I had forgot all about this. I had a 55 Chevy Belair with. Wore out rear end yolk. Somebody sold me the sleeve that I was able to hammer on right over the damaged yolk machined fit I wonder if any of you fellas heard of those… bob Quote Link to comment https://www.bigmacktrucks.com/topic/74624-power-steering-pump-rebuild/#findComment-559831 Share on other sites More sharing options...
mowerman Posted October 10 Share Posted October 10 The yolk had the same issue. It was all wore out right where the seal goes. Quote Link to comment https://www.bigmacktrucks.com/topic/74624-power-steering-pump-rebuild/#findComment-559832 Share on other sites More sharing options...

mechohaulic Posted October 11 Share Posted October 11 1 minute ago, Joey Mack said: I like the way you think Mech.. seems todays " mechanic" will just replace a worn yoke . days gone by the speedi-sleeve saved an owner a lot of cash. don't know if the computers would be able to diagnose a leaking seal today. a good friend and owner operator had his KW upstate with a problem. took it to a dealer only to be told " we don't know the answer to your problem; hopefully you can make it back to CT. that's after 3 hrs of jerk around at $200.oo per.

Popular Post Joey Mack Posted October 11 Popular Post Share Posted October 11 I was taught to use an Arbor press to install them, and i would buff the leading edge with emory cloth to reduce the risk of cutting the seal, and I also put a small kiss of RTV on the inside of the sleeve to seal any imperfections on the yoke, shaft, whatever.... ya know what i mean? 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74624-power-steering-pump-rebuild/#findComment-559857 Share on other sites More sharing options...

Joey Mack Posted October 11 Share Posted October 11 Here I go again.... Mech, you talk about using a computer to diagnose issues..... one of my co-workers rolled a laptop to a truck to diagnose why one of the headlights was out.. He did that first... yes, I had to learn that these new turds have L.C.M.'s.... light control modules... in his case it was a bad bulb... I smacked my forehead and asked where the hell am I??
