. Pretty easy fix. Since I had already taken the tranny apart I cleaned it and rebuilt the diff. Side note - how many concave washers does this thing have!? However when putting it back together I came across a piece that has me scratching my head. It is sandwiched between the spur gear assembly and the slipper clutch. This thing adds 19g of rotating mass to the drivetrain and I see no discernible use other than decoupling the drivetrain from the motor (which is what the slipper clutch is for). When turned it has a viscous feel to it. It says Losi Patent Pending on the side.
Aside from that mystery part I am still deciding if I want to rebuild it back to a buggy or keep the truck format. I really dislike the crude body posts for the truck version. I don't know if they were home made or early mods. The car does not have the 5 link suspension system but does have the holes for it. The rear A arms were replaced for RPM ones. Maybe I can put a buggy body and keep the truck tires for a vintage truggy build.
I’d love to know your thoughts. Thanks!
The truck had a JG sticker on the graphite plate which i removed while cleaning, so it makes sense it was a JG kit buggy to truck conversion and not hand made by the previous owner.
