my power steering pump going out on my 74 f100

i had auto parts order me one.

my question is what do i need to know about taking it off and putting it back on..

i just learn i need a puller to take off the pulley..

i hope i can take the power steering pump to a shop have them take it off

and put new 1 on it

then i can hook it back up to truck

i heard you have bleed power steering pump ?

 

You do need the puller. Make sure when you put the new pulley on that you put it on in the correct direction; if you put it on backwards it will never come off.

 

it does have a hum. i had added power steering fluid it was real low not sure if
its the pump leaking or the hose leaking
when i had added fluid it felt like the steering wheel didn't wont to turn
maybe air ?
should i just try to replace hose first ?
and howto bleed it ?

 

Should use Type F for the power steering. The old Thompson pumps do not play nice with universal power steering fluid.

It will come off ! I have removed a couple that were put on backwards . With a torch !!!

 

keep in mind that the bracketry for the pump is behind the pulley also, so remember to get that on before installing the pulley onto the new pump. you can rent a pulley puller kit for a small deposit or buy one either way for roughly $30. as long as you have some sort of workbench and maybe a strong friend to help you, shouldnt have any problem doin that yourself. just take a silver sharpie and mark the front of the pulley with a big F or something before removable to avoid this backwards installation issue.

hoses can collapse on the inside so i recommend changing those, too. maybe even before you waste money on a new pump. theres a few different part numbers for the pressure hose so make sure it matches up to your old one. the return line can be replaced with bulk hose(parts stores should carry actual power steering hose.) another alternative you could use is either some better quality fuel hose or transmission cooler hose.

as far as bleeding. fill it to proper level and run the engine. make sure it stays full(to the low mark on the dipstick) air bubbles may/should occur and probably have to add more fluid a couple times.

after this, work the steering wheel all the way to the right, check and add fluid if needed. then work the steering fully to the left, check/add again. repeat this several times and it should be bled fairly well. at this point the fluid level can be more to the middle fill line, you dont want it completly full or overfilled while cold, i believe the dipstick even says "CHECK HOT" . it not going to be HOT until a drive around town. you have to allow room for the fluid to expand so keep it at the cold level until you know its warmed up well.

 

thank you for the info
