Ok so here's the first progress. Got up early this morning and torn the little 38 down in 1.5 hours except the engine which I will do once I sort the base, I hate having bits everywhere getting mixed up and lost.
I'm going to run through a few photos because there really isn't any reference of these edges being pulled apart or restored. Thanks CyberJack for that parts diagram it really helped, so I'm going to post it up here for easy reference. The guard cover comes off with 3 bolts exposing the blade belt and puley mechanism, I recommend removing the blade and the pulleys before removing the mechanism off the engine. I did it the other way around and had to clamp it in a vice to remove the pulleys, depending how rusty or locked up it is you may have to do it how I did involving the mech off the engine and clamp it in a vice. First pulley has a grub screw in the belt track so losen that then undo the bolt in the middle that connects to the PTO shaft on the engine, it should slide out with a keyway once the 4 bolts are removed from the side of the engine. Second pulley on the blade side is a bit more difficult and may need to be clamped in a vice. I clamped the pulley in the vice then clamped the blade boss with a pair of multigrips on the outer edge of the shaft and used a long bar on the multigrips to crack the thread free, you can then knock the shaft pin out from the pulley side giving you access to the bearings in the mechanism of you chose to replace them. You could also try clamping the blade boss in the vice and use the little hole in the pulley track to undo the thread but mine was so tight it was bending the screw driver as that was the only thing big enough to stick in the hole, like I said I had to use a bar to crack the thread free.
There really isn't much to it, it looks complicated but once you get your head around how everything is connected it's easy so hopefully this post makes it a bit easier for anyone else as I was a bit hesitant before I started. The rest is straight forward
