Vickers power steering pump

[TomC]

I'm in Quartzite, Az now. Beautiful here. Came in yesterday, checked my engine and discovered by power steering pump is leaking through what looks like a small relief valve at the top of the pump. I have a rule not to do repairs on the road. Can I just put a couple of hose screw bands with a piece of rubber or wood to seal the opening until I get home? Or will it blow up? Thanks! TomC

Pop the pin and fix the leak sometimes a standard 0=ring will get you by till you find the square cut seal that goes there not a hard fix if I was there I would do it for you.lol the weather is going to change it started raining here in Scottsdale with the wind around 6am

Hi, Guys. I have had the same problem in the past on a Vickers power steering pump on a 8V92. I was under the impression that the pump only leaked when the engine was off. Had the pin and seal replaced in Memphis. Brought the bus home and parked for a while, everything seemed ok. Had to go to Titusville, FL. everything still ok. Stopped at a rest area in GA. got up next morning to walk the dogs, power steering fluid every where. Filled up power steering tank, took off, thinking it wouldn't leak till we got to destination. Turning in the parking lot the steering gave out. You could pour in the fluid and it would pour back out. Finally managed to get back on the road by standing up in the seat to turn the bus. I figured the pump was toast and I was determined to get hoe to Memphis, TN. which we did. Took it back to the shop that worked on it. They did the pin and gasket again. Brought it home parked it. This last cold weather spell I was determined to start it up so if the house power went out we had somewhere to stay. The pump made an awful noise and could feel the problem with the steering wheel. I wish I had replaced the pump the second time, instead of putting in the pin and gasket. Mine is a marathon conversion and it is almost impossible to get to the pump located in the back of the motor. I told my wife of 53 years to leash up the four dogs and be ready to abandon ship if we had to quickly. Making turns was the problem, going strait was not. Is this a problematic thing with the Vickers pump ? I have driven commercially since 1966 some 6 million miles and retired, hoping enjoy life, but I do know what happens when fluids hit hot exhausts, and more than likely would not have to worry about replacing the pin and seal. Luck would have that all the fluid escaped while parked, and hence it was not a problem.

Safe travels to all, Thank you for the site so we can share experiences with others.

We have a Vickers pump on our 671. Not sure its a similar pump but has been issue free for 42 years now.

We blew a power steering line a couple of years ago on the freeway. Probably drove about 30 miles with no oil in the system before we got to the shop. The pump survived, but I bought a spare just in case. You know if I didn't have the spare it would have crapped out instantly. Of course, on the GM the pump is super easy to get to.

the harder something is to access, the more likely it'll  cause issues.

Those pumps are not that hard to reach on a Prevost ,the Vickers pumps on older buses are not that bad with the low pressure ,on a front end heavy Prevost high pressure system they give you problems,the front axle on Prevost carry more weight than the GVW on GM buses lol not quite but close
