Since last post I have made baby steps on the JRXT revival.
The truck is apart!
The hinge pins weren't moving with a hammer and punch until some of that embedded grit got out of there and the parts were warm/pliable. The ultrasonic cleaner has been run multiple cycles on everything with Dawn and hot water. Several rounds of muddy water created.
I filled a dozen or so holes in the chassis with epoxy used for fiberglass layup. (oversized/extra holes) I need to get a 100deg countersink to restore the ones I'm using.
The whole steering linkage is going to be replaced with correct JRXT geometry stuff (FW and DPRC) and mounted back into the proper hole locations in the chassis. That old linkage might've been Houge, but it was some non-JRXT application parts and didn't have a draglink.
Bearing set on the water currently.
A&L Yellow monster truck wheels purchased; going trenchers and ribs for tires. The auction for these wheels mentioned something about needing different axles or an adapter sleeve up front? I measured ~.187" front axle diameter. Tell me more if this A&L wheel bearing ID detail sounds familiar to you, it is something I'll have to deal with.
Traced a shorty lipo on plastic cutting board and attacked it with a wood router; disc sanded to perfection.
I have an R1Wurks servo bracket in the pictures, hopefully it clears the linkage. If not, refill servo holes with epoxy and plan B.
Body and gear cover on hand.
I knew the trans was well beyond a set of diff rings and balls before I removed any screws, so I ordered a complete assembly off Ebay. When you'd rotate the top shaft it would randomly lock up; it sounded like a gritty mess. And I needed a spur gear anyhow.
Removal uncovered the transmission had fire damaged cases!
It looks like maybe a torch did it, on the surface that mates toward the bulkhead. The diff had 11 rusty balls that seem melted into the gear. The bearing pocket for the top shaft was broken out, and that loose piece of plastic was causing the lock up.
The gear teeth, top shaft, outdrives all look useable though.
The corrosion/pitting on the shock bodies and shafts makes me think this truck was used as a garden gnome for an extended period.
The shafts still move. Throwing the shocks in the ultrasonic as-removed, 3 of them still had oil in them when I disassembled after.
They're pretty bad. I can't help but notice that RC10T front shocks are about the same length as these.
