    HM-282 Diff pin removal

    How do I get the pin out of the center of the diff on my getrag? I've already got the diff out, that was easy. Are there snap rings holding the bish in or do I just tap it out? I dont want to damage it. This thing has to last me a while under some pretty rough conditions.

    So, how does the pin come out? I wanna get my TG LSD in there already.

    there is a rollpin that holds the diff pin in place. you need to drive out the rollpin (also called a split pin) and the diffpin will slide right out.

      if you have the plastic gear, make sure you take it off first or you may mess it up..

      not sure about the metal pickup style, i haven't taken that diff apart yet...

        Awesome, got it. Thank you.

        Now if I only had a vise to compress the LSD for the install.

              Ahh... hadn't heard of them before. I gather from other reading that their product is like PG's...

                I believe it's pretty similar. It's just 2 steel plates with 920lb (combined) springs in the diff sandwiched between the spider gears.

                I had some installation difficulties because the clips they sent werent drilled properly, but after being sent some blanks to drill myself I was able to get it installed in the diff. Just waiting on everything else to arrive and then I'll be able to give some feedback on it.

                  Mine works so well that i had a hard time doing a burnout in the waterbox, even with the E-Break locked in i kept dragging the rear tires foreward.

                    That's what I like to hear.

                    Anyone know the torque specs for the bellhousing bolts?

                      bellhousing to engine or bellhousing (as in front case half) to the rear case??? either way, just tight.

                        Sorry, I meant bellhousing to the rear casing. I got em pretty tight. Any tighter and I'd be worried about cracking something.

                            Damnit. Should I pull it back apart and switch out the copper permatex then? haha.
