DIY restoration of a World War II-era Triumph 3HW motorcycle

It was auctioned by the Indian Army post-independence. I've recently acquired it with a lot of effort & will be personally restoring it in my home garage.

BHPian cosmic_ocean recently shared this with other enthusiasts.

So I had restored one way back in 1995 from scratch (MYV-3962-photo available on team-bhp images) which I later sold due to paucity of time. The memories, however, never stopped haunting me.

This is a World War II Military Dispatch riders mount that was used by the allied forces during the war. It was auctioned by the Indian Army post-independence.

So after having recently located and acquired one with a lot of effort, I will be personally restoring her in my home garage. Will document the restoration with pics and descriptions, as often as possible.

Here are the first look images of the bike as of today.

Managed to completely strip the motorcycle and disassemble the engine & power train a while back. The big end bearing was in good condition but all 3 crankshaft bearings needed replacement. I managed to order them from overseas and they came from the UK last week.

Below are pics of the crankcase with the new bearings fitted. I used Loctite 648 retaining compound to secure the bearings on the shafts. The flywheel also came back balanced and trued from the machine shop.

Oil feed & return pipes that were missing, made from a copper tube as per the spec and soldered to the union. They help draw and return oil, under oil pump action to the external oil tank.

Gearbox bushings made on the lathe. Top gear sliding dog and constant mesh layshaft gear that had worn out, imported from the UK and assembled with new bearings.

Substituting gaskets with Loctite 510 flange sealant, that does a better job.
