58GreenMackB Posted July 8, 2017 Share Posted July 8, 2017 Can anyone give me some recommendations on good pitman arm pullers for a 1958' Mack B Model? I bought a "Heavy Duty" one from OTC and all I can seem to do is spread it and never actually get enough tension to pull it. Any help would be greatly appreciated!

theakerstwo Posted July 8, 2017 Share Posted July 8, 2017 Do not use heat like your going to hear.A air hammer will help.Also i cant remenber pulling one on a B model but a big sledge hammer on the bottomside agains the lever while some one wacks it with another hammer on the top side if the fender will allow. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/50424-pitman-arm-puller-recommendations/#findComment-374456 Share on other sites More sharing options...
h67st Posted July 9, 2017 Share Posted July 9, 2017 After you remove the bolt, drive a chisel in the gap to spread it, then spray with PB blaster and tap all around it to spread the oil around. I ground some grooves in the sides of the chisel to give it grip (it will pop right out if you don't).

Hobert62 Posted July 9, 2017 Share Posted July 9, 2017 Yes be very careful driving a chisel in to spread it. Local guy told me he has a puller type thing that you tighten and it drives a wedge in to spead it open a little. ( I haven't seen it). He had a chisel hit him in the hmmmm "nuts" and he bought this thing. Its Prob. snapon.

Popular Post 58GreenMackB Posted July 9, 2017 Author Popular Post Share Posted July 9, 2017 I got it. I do not have the box that has the bolt going through it. I have the one that only has the large retaining nut. What I did was use the OTC 7310A puller. I broke the side support bolts that came with it so I replaced them with grade 8 hardware....no more wing nuts flying across the truck when they snap off. I took a huge C-clamp that I use to compress brake calipers and snugged it up. Put my Milwaukee M18 Impact on it and let her rip. Popped right off! Sometimes just takes a little bit of re-engineerng to get the desired outcome from your tools. Thanks for all the input. 4 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50424-pitman-arm-puller-recommendations/#findComment-374501 Share on other sites More sharing options...

Freightrain Posted June 9, 2019 Share Posted June 9, 2019 After a few options I used a slack puller to get my pitman arm off. Tighten it, smack with bfh and off it came.

theakerstwo Posted June 9, 2019 Share Posted June 9, 2019 A good snapon air hammer is a good tool for pitman arms.I have used them for years.
