Replacing the Hydroboost....

[quadracerx]

I am in the process of replacing the Hydroboost on my 1987 C3500 GMC Dually.

According to the instructions included with the rebuilt unit, I have to re-use the Mounting Bracket. The Bracket is held on by a giant 4 sided locknut.

Anyone know of a wrench to fit this? Or the proper way to remove it?

I really dont want to use a hammer and punch but...?

Thanks again for your help... This forum is amazing!!

A big pair of channel locks, a large crescent wrench or open end

Maybe even a pipe wrench. You might have to put the unit in a vice to hold it, then use a pipe wrench to break it loose.

Hammer and chisel. I did this and after a few pops it started to turn freely. Soak it good with some knocker loose first.

I believe there is actually a socket made for this, but I'm too damn cheap to buy something like that. Hammer/chisel works good lasts long time!

I've seen where people use a modified trailer hitch. Weird.

People with welders and welding skills can work wonders!
