Piston 2

Here are some detailed photos of the piston.

 

Piston

Today the piston saw the world again after decades!

Fairly dark from the carbon deposits.

It looks fine with some small marks on the side, will have to clean it up and check the rings.

I wonder if I should try to reuse this, what do you people think? Otherwise I’ll have to source a good tv175 piston.

Engine removal

Today I took the engine out of the frame so I can more easily work on it. It looks like it’s definitely been stored in a barn sometime under it’s life since I found hay on it!

The engine also showed a crack on a stud for the crankcase cover. I saw the same on the rear brake hub, I figure some former owner must have dropped the bike while trying to change rear tire, or it was that now famous repainter.

Hopefully I can weld the aluminum case so I can rebuild the metal around the thread and if the hub is nice and strong otherwise I can still use it. Since Spanish ones are dead hard to find and Indians are mostly ok I prefer to keep my original.

The whole point of this resto is to not unnecessary throwaway stuff that actually does still work fine.

Exhaust and manifold

The exhaust is in a really bad shape. It has surface dirt and rust on it.
The battery has been leaking sometime in the past, a couple of decades ago, and it has left white marks on the engine mounts, exhaust, kick, battery tray and other things in it’s way.

The kick and exhaust.

The leak on the engine mounts and other parts.

Same surface dirt on the manifold.

The complete removed exhaust, I dont know if it is possible to clean out and reuse. There is no fracture or part missing, just dirt and rust.

Some more images

This model is a battery model.

The bike is missing the speedometer. Will have to replace or ignore 🙂 .

Strangely enough this bike has the single seats although the model came with a dual seat. Although some retailers sold the single seats as an option.
