MC8 Power Steering Pump Removal ?

[JackConrad]

8V71 in an MC-8. I disconnected the 2 hoses (power supply & return) and removed the 2 mounting bolts as per manual. Pump is loose, but only moves out about 1/4-1/2".  Any suggestions?  I can't remember if this was a gear drive, or something else?  Jack

Just comes off one way Jack the housing has a slot rotate the forks on the pump to that slot and it will come out

good luck

There is a fiber disc about a 1/2" thick that is the coupler between the drive and the pump.  It floats in there, so you will be able to feel it move around.  What I did to make installing the pump easier was I rotated the engine around (if you do this make sure the engine stop lever is at "stop") until the slots that the pump drive go into were in line with the clearance slots on the cover on the back of the engine.  That way you align the tabs on the pump up and down, and slid it it, and it slips right into the coupler disc.

Hey Brian,
Why didn't you suggest that 11 yrs ago before I replaced my first one inside the bus on an MC9!
I swear I was so dang mad and frustrated with that dang thing! I could not for the life of me get it lined up! I spent 4-5 hrs fighting it! When my uncle came by that evening to see how it was coming, I told him "I musta got the wrong pump or something cause it just won't line up right!"  2 minutes later while still dressed in good clothes he crawled back out and said "there put some bolts in it and hook up the lines we need this bus in the morning!"

OH I was so mad I could have spit enough blind rivets to re-skin a whole bus!

Well, I have to say that what I wrote makes little to no sense until you have gone through this stage; I swear I was so dang mad and frustrated with that dang thing! I could not for the life of me get it lined up! I spent 4-5 hrs fighting it! When my uncle came by that evening to see how it was coming, I told him "I musta got the wrong pump or something cause it just won't line up right!"   

In my case I couldn't rotate the nose of the pump to even get it out until I did that juggling of the engine.

Power steering pumps are high on my list of things to change when the engine is out, right after compressors and clutches!

Beian I don't know how, but somehow I managed to get it to fall out almost instantly, and that is why I could not understand why it was such bei-octh back in!

  Anyone recal Renault R5's (LeCar)? To change the starter you had to undo the left engine mount and jack up the motor, otherwise there just was no way. 15 minute job doing it "the right way".

  I stopped in at this shop, and this young kid, all of about 16, he's covered head to foot in grease. Hes workin on this R5, hes got the whole front end off, suspension off, radiator out, and hes now pulling the tranny. I thought he was putting in a clutch. He said starter, and I had about all I could do not to laugh, I think if I had told him how to do it he would have set that car on fire.

  So the steering pumps another thing I should get to, I guess.......

I had a hot rod 63 Pontiac. That was the way to pull the starter on it also.

The transmission was what got me. I had pulled plenty of 4 speeds from Chev's. So I thought nothing about pulling the trans out of the Pontiac until it fell in my chest. It was not the light weight aluminum but cast steel. did I say heavy.
