Still trying to reach the power steering pump on a 8v92

SanyikaV · June 18, 2018, 09:29:11 AM

Would it be possible to reach the pump on the forward (front) of the engine going thru the opening of the radiator (removed) ? I don't see how anyone can possibly go over the batteries on the passenger side to get to the pump. Any ideas ? This is a 1991 Marathon Prevost

My PS pump is on the RH side behind the bats also and I can access it by either removing the house bats or laying something over the bats and stretching out on it. Your's might be different though since it is a few years newer.

That's the way I got to it when my pump started leaking just sitting in barn. Over the batteries (covered with cardboard) and squeezing in and thank goodness for long arms. Very tight fit for sure. Just o ring fix, purchased from Prevost on mine. That was about 3 or 4 years ago. A skinny mechanic would fit. I'm 6'2" and about 240. It was tight.

If the bed is a north-south orientation you likely have easy access beneath the bed to a panel Prevost installs in the floor, that when removed gives direct access to the pump, compressor and alternator.

You need some long arms to reach the PS pump from the hatch or stand on your head,I remove the batteries

The power steering pump on my 4905 is right there on back of engine. Just open tailgate and there it is...lol

My cabinet maker converter (Cole Custom Coach) built the bed frame solid to coach and there was no access to engine. Had to go in from above batteries. A pita.

your starter wins hand down

This is one of the many reasons originally for a V-drive. Everything on the engine, except the oil cooler and the starter, are accessible. Then all buses now are T-drive. Especially with 2 stroke engines, that puts the alternator, power steering pump, air compressor on the back of the engine-which is facing forward and buried in the bus. I've seen a few home made T-drive conversions-mostly on 4104's where the converter made side access doors to easily get access to the back of the engine. Good Luck, TomC

Water pumps are a pita on V drive

TomC · June 21, 2018, 08:11:31 AM

Yes I agree that water pumps are also hard on V-drives. That's why I just replaced mine when I had the radiator out for enlargement. With the radiator out, no problem. Good Luck, TomC

On 4905, the radiator is hinged. Drain coolant, remove rear bolts, disconnect rad hoses and swing out on hinges.
