Mystery wheels

[Glen Plumridge]

Slowly stripping LP2A hull number 4425 and gradually getting parts and supplies together.
Only have the diff assembly to remove from the hull before I can get it sand blasted and get paint on the internal section.

Most parts have come off fairly easy and look like they will free up with a little work and lubrication.

Used the, weld a nut to the stud method to remove sheared off bolts and that worked well for the most part. Some impact after the weld cooled also helped the more stubborn ones.
Only have one threaded lug that was not recoverable.

First engine ended up being only good for parts as one of the cylinders was too far gone to re bore and putting in a sleeve is a last resort, so back on the hunt for an engine to rebuild.
It was only cheap so I got a heap of spare internals from it anyway.
The gearbox has freed up OK so might have a win with that one.

Tried a few methods of unseizing some of the worst track sections.
Soaked in citric acid solution. not much changed
Heavy hammering and flexing. not much changed
Sat the track section on a low temp fire and then worked over it with hammer once cool. This got all of the seized links moving and allowed the pins to be punched out. Pins were heavily pitted.


Found a place with 7/16" 4140 round bar so there will be new track pins if the trend continues of finding poor condition ones in the tracks so far.

Were pins hardened to a known rockwell number?


Getting some paint organised so I can protect items once they are reconditioned.
