Out comes the angle grinder
I wanted to get the engine casings from the Polo and the Pushpak stripped right down so I could check them over and see what work needs doing to them.
The rear hub of the polo was giving me a lot of trouble as the threads were stripped on one of the three holes for the extractor.
I solved it by putting an old rear hub nut on the layshaft then hitting it with a big hammer.
This pushes the layshaft through the hub. It obviously only works if the endplate isn't it place but seems to work OK otherwise.
I will have to repair the hub thread before I use the hub as it cannot be removed that same way from a built engine.
I removed the tank and toolbox from the polo as well as the seats and the forks.
The forks took ages to strip down. I am not sure what was stuck but it felt like the fork link caps were sticking.
After that I moved back onto the polo casing. Now the rear hub was off I could removed the old brake shoes and the cam. I found that the rear brake arm had been welded to the rear brake cam (rather than them taking an hour to change the cam and arm). Maybe they had struggled to remove the rear hub like I did.
It took some very careful work with the angle grinder but in the end the cam and arm were in the bin with no damage to the casing.
I had another look at the broken off cylinder stud. There is only about 3mm sticking out so there is not quite enough to grip with some molegrips. I will have to see if there are any special tools available to try and remove the stud.
