Day 6 - Cleaning & Starter Motor

So now I have the engine indoors, the first thing I decide to remove is the starter motor. Very easy to come out with the engine so accessible. I take the starter motor apart and notice a whole load of black dust come out which I imagine is the wear of the brushes over time. All the starter motor parts laid out...

Gave that a good clean and followed the service manual about where and where there should not be continuity, and ensuring the brushes don't need replacing. The service limit on this is 4.5mm and these ones were about 11-12mm - so tons of life left in them.


But the day wouldn't be complete without finding another problem. The exhaust stud at the top of the picture is the problem. It's not screwed in fully and all attempts to get it screwed further into the cylinder head was pretty much made impossible by the fact that the stud has siezed up inside the cylinder head. I need to get this stud properly screwed in like the others as that will also contribute to the exhaust header mounting plate not tightened down enough and be a potential for exhaust leakage.


So now to source come more tools, wire brushes for scrubbing down the engine, and a blow torch to apply some heat to those studs and see if I can work them free. Although the exhaust ports are looking better and slightly cleaner than before - just need to clean up the rest of the exhaust ports and then onto cleaning the rest of the engine.
