I've been putting in a few hours on this tractor overhaul without appearing to be getting anywhere, lots of time-consuming tasks. Also my long list of parts still hasn't arrived, I did buy a big box of assorted imperial O-rings, the hydraulic system on this thing runs on O-rings the way a modern car runs on hoses. I should have a lifetime supply of O-rings left after the job's done though.
I had started to mill the flywheel using the rotary table
really wasn't happy with the setup though so I decided to transfer it to the lathe. I had to make an arbor to mount it, was racking my brains for material for the arbor and remembered I've had 2 cast iron multi-belt pulleys acting as doorstops in the shed for years. This one got a bit of a trim
and the flywheel got clamped to it and machined flat. There's a lot of deep heat-cracking in the flywheel, good enough for the tractor I think but it wouldn't be going back into a vehicle that had to drive nicely. Took ages to machine, I whiled away the time renewing O-rings on various hydraulic components while the lathe did it's work.
then sent my arbor back to join it's friend- they can chat about the weight loss.
I cleaned up all the cast-iron dust from the lathe and then mounted the 700 x 102mm bar of 4140 to make a start on the piston. This is only about the second time I've used the fixed steady (or steady rest), took a while to get it set up. Also I was glad of the gantry over the lathe. Made a start on getting the new piston to size.
I've decided it wasn't all bad news having to purchase this big lump of stock to make this little piston, I'll at last have some material to make the missing headstock centre for this lathe as well as a spindle-mounted collet chuck. One day.
This from a couple of days ago, the clutch fork pivot shaft was badly worn at both ends where it rotates in a pair of bushings in the bell housing.
I used the lathe to cut out the plug weld that held the lever on one end, turned it down to fresh material then used the mig to make it fat.
turned it to size then welded the lever back on. Ready for another 50 years.
