My LST and Muggy Conversion Thread

[JThiessen]

Just a small update: I finally got around to starting some of the assembly.
Got the Diff's rebuilt and installed in new aluminum cups. Used Muggy ring and pinion in them to get the ratio down a bit more to help with spur/pinion choices later on. One thing I noticed is that the gear mesh (ring/pinion)changes rather significantly as I spun the gear. I've never experienced this with the Traxxas and Savage diff's that I have rebuilt.

Installed the diff's into the Hot Racing Aluminum bulks and rear bulk support. Also used Hardcore Racing titanium upper plate, and hinge pin retainers. And of course the Lunsford Ti hinge pins. One of the bulks did not get the holes tapped very well - every one of the fasteners on it was damn tight - even the hinge pins took some extra work to get in. The other side was fine. Also installed the Ti Arms and Dynamite carriers, and the Losi hardened skid plate.

Remember - I'm converting an original LST, so I wasn't prepared for the carrier pins to be too short. Luckily I had two new Muggy A-arms sets, and stole the pins out of those. But after installing them - it looks like they are too long. I used all the shims they gave me, but looks like there should still be more. I'm also not certain that I installed them correctly - should the shims be used on the inside, or the outside? I also did very little shimming on the hinge pins. Should these be kinda loose, or nice and snug (but still allowing the arms to rotate freely)??
