I can see a crack, the case is goosed..

 

what was the reason for you stripping the engine?

 

It's normal for the bearings to be worn through to the copper... you've pointed out that they are original bearings, so 40 years of use.... That's not bad dude

Try doing the same with a lawn mower engine

Cam bearings should look like this...


But I often find them looking like this...




And sometimes you find mains that look like this

 

You're a fibby fibbingston aren't you.

 

The other two are still white metal, just the drive end that's worn through, makes sense as all the weight and the drive is that end.
I'm really happy with the mains, not even a hint of copper on any of them but as advised, I bought new anyway.

 

where are you looking??

 

It ran fine but leaked oil like the Exxon Valdez.

 

Where did it leak oil from?

 

This pic paul

 

The flywheel oil seal had blown comprehensively and the pushrods weeped.

 

I can only see casting marks in that pic, no cracks there!!

 

I concur, it's a casting mark and some kecky crud from inside the engine.

 

I wont say one way or another unless its in my hands my ocd doesent allow diagnosise by post
What an awesome band name though lol

 

You are right ,I had my beer googles on...

 

I'll have to swap the cam drive gear, do I just grind out the rivets and bolt it on the new cam?

 

You grind the rivets off on the cam side... drive the rivets out, drill the holes out to 8mm, and face the cam on the lathe so the bolts have a flat face to bolt down on to

 

Would you recommend cutting a thread in the gear?

 

Definitely not dude!! You could end up being off from the cam by 1/4 of a thread, and your gear won't run true then!!

Special cam bolts and thread lock is all that is needed

 

Finished the wheels today.
Quite pleased with them given the entire expense so far is £90 (excluding tyres).
