I just broke a brand new pitman arm puller and the pitman arm didn't eve budge.

Any idea how to remove the pitman arm on a '80?

You have the right idea, you just need a better (american made) puller.

Also.....have an old wet cloth cose by to cool the steering output shaft once the pitman arm pops aloose......first heat the pitman arm at the fit with the propane torch......once you have good pressure on the new puller at the pitman arm.....use the hand-held propane torch again to heat evenly around the pitman arm where it attaches to the steering output shaft----BUT keep the flame away from the puller jaws and output shaft and bottom of the steering box as much as possible (the jaws will get fairly warm though)....it may take a minute or two and you may have to tighten on the puller a little more until the armpops aloose

We ended up doing this after buying another puller. Much easier when we applied heat.

Thanks!

Once you have good pressure on the puller and nothing seems to be giving way.....find a BFH and RAP that bolt on the puller to put a shock on the stubborn part....thats the method I was taught 35 years ago, has yet to fail me

That's the ticket....

My shop we always use air impact wrench, hundreds of lil shocks add up!!!

Do you know that when a water soaked rag hits hot steel it make it more brittle than what you started with?

Use oil to quench steel.

Worked fine for me

I use a cutoff wheel to cut nearly through, then a chisel in the cut to break the arm. Got tired of screwing up pullers and fighting 'em.

Yep, get a good small sledge and beat the bejeebers out of it. It'll come out (or else!).

I have owned an Ingersol Rand 231 BF Impact gun since 1978......but, you can strip puller threads by rattling the gun against a puller screw......better to take a BFH and directly hit the screw and impact the part under tension in the direction you want it to come off. I used to also do this to tie rod ends but, in my old age, I now have a tool to remove tie rod ends without destroying the rubber boots.

OOOOOOOOOOOOPS.....I forgot about the oil
