A bit of an update on the Raider 10.
The side discharge deck went in the skip up at the farm. The shell was really beyond repair. I should have stripped the wheels etc off it, but at the time didn't think too. Needed it out of the way. I could have done with them now.
Stripped down the engine today and sure enough the con rod was broken. The bore looks good as does the piston, which looks standard. The valve seats are perfect, but the crank needs a regrind and the valve head seats touched up. I'll give it a clean and take it to an engineering shop that specialises in vintage engines etc. We'll measure things up and see what needs to be done and see what I need to get.
For a 42 year old engine things came apart relatively easily. The flywheel took a bit of shifting, but using three legged pullers and a couple of good wacks on the puller end, it came off. Getting the crank out was a bit harder. I undid the alternator back plate, which didn't want to let go of the main bearing. So the crank was removed, with some persuasion, with it in situe. On the bench, using a couple of chisels as wedges, back plate and bearing parted company. No bearings were harmed whilst doing so. The crankcase seal on the drive side will have to be replaced as it is a bit worn.
I'll take some photo's in the morning. I wasn't touching my camera the state my hands were in.
