Hey Man have any of you ever have a power stearing pump lock down an snap the fan belt. What would have caused this ? Can i put another one on without having this happening again. or could it the box that needs to be changed out. I may be the cause of the problem ,it has been slowly leaking fluid( the PUMP) and i have been useing power stearing fluid not ATF . Some time have the brain power of a rock Geeeeeee THANKS

Palwackie,

You should be using ATF in the PS pump and not PS Fluid. But I am not sure if that could have caused it.

I have seen them lock up and throw/shreed the belt also, it can happen.

More than likley, you will need to change the pump before trying it again.

Also, Are you SURE it was the PS Pump that locked up?

Make sure you check all the pulley's before changing anything.

I would place a bet on the Vacuum Pump before the PS Pump

if the bearing for the pump/impeller is gone it could lock up and burn
the belt up.

basically the belt turns a pully which turns an impeller (which moves
the fluid)...i cant see fluid locking it up (maybe if it was cement mix).

most power steering fluid is repackaged (aka higher priced) atf...
the viscosities arent gonna be dramatically different.

w/ the belt off the ps pump see if theres play in the pully...can you
turn the pully ? you could also have a bad check valve in the pump
but again i dont think that would lock the pully/bearing up.

hows it been steering ?

the leak may have been a sign that the pump need(ed) replacement

Hey All, The new deal today .Got new belt and pump. Pressed old metal pulley onto new pump( tight fit) Installed belt added fluid,purged air out. Cranked up made several reves back an forth on stearing . every thing seems ok .No noise ,NO leaks Stears great . Take out on the road for about 20 miles and 7or 8 turns. Back out from store , have a heck of a comotion going on under the hood . New fan belt chewed up in radiator , power stearing pump pulley laying on store parkingl lot . Pump pulley shaft blue an smoking hot. After getting home ,pull the pump back out shaft is ruined ,pulley is gone also.I can turn shaft by hand easy and it will shoot oil out 20 foot . I'M Really concerned NOW > ANY IDEAS

something else is causing it <today im playin'
the part of stating the obvious> !

could an idler pully or another pully be locking
it up ?

what about the alignment ? is the best tracking
straight / lined up right ?

Hey Brush. I am away from the truck for a few days now .so being able to check things out will have to wait HOWEVER Ideas that can be concived for a fix are open.Wouldn't some thing have to keep that pulley from turning that pump .Like a pressure buildup or maybe something restricting pump flow . Is the pump a centrifical pump and would turn even if the flow was blocked off. How is that power stearing box gearbox or more imporantly how does it work? I really had no dealing with the stearing system. Your turn

Ok fellow dieselers, Back again . Worked on the ole 1996 F-350 again. THE FIX --New power stearing pump and new pulley. Purged nthe system with about 1/2 gallon of new fluid . The old stuff was nasty had grit in it ,Bet thats what got the first pump. Any way thanks for all of you'r help . PS 1996 model uses power stearing fluid , changes in year 1998 to trans fluid (per ford Foreman as he looked it up) Thanks Again

sorry just now seeing this and the post from 2/25...wasnt ignoring
you, somethings up w/ the forum <new post "switch">.

good catch w/ the flushing...could have been plugged up enough
that under pressure the new pump couldnt turn.

hope this solves the problem.

heres a how to on the steering pumps...
