Lister Generator - Making A Camshaft Extension Safety Guard and Repairing The Air Cleaner Stud

The old Lister workshop manual I found online showed a guard for the camshaft extension that pokes out the front of the engine. I thought that was a very good piece of gear to be at the top of my list of things to do to this generator. Here's the finished product:

Below is a photo of the shaft prior to my guard being put in place (the photo is before I removed the alternator and pulley). The shaft is hanging out in space, just waiting to grab someone's clothing:

I had a piece of exhaust pipe I'd cut from my pickup truck when I installed a turn-down exhaust tip. It's about 4 inches in diameter, which seemed perfect. I cut it to length and also cut a section off for a removable end, to account for the crank handle design.

I squared the ends of the tubing, since the power hacksaw didn't make a perfectly straight cut.

Here are the pieces, ready to bend and weld in place.

Below is a photo of the finished product prior to painting.

This next photo shows why I needed a removable end, to give room for the pawl tube on the crank handle.

Painted...

... and installed:

Here's a photo of the end piece taken off and the crank handle installed:

This next picture shows the factory guard. I may make a flapper similar to this in the future.

After finishing the camshaft extension guard, I tackled the broken air cleaner stud. The stud snapped off when I tried loosening the nut to have a look at the air filter.

I ground off the broken stud...

... and welded a screw in place:

Ta da, now I don't need a wrench to check the air filter.
