G'day Jace et al.,
I recently redid mine. I haven't actually put them to the test as the machine is an ongoing project.
Firstly, be aware that the engine clutch on mine was an asbestos compound. I replaced it and the wheel drive clutches with 1/8" cork cut from a sheet. I had a heck of a time finding the sheeting. Everyone could sell me rubberised cork but I doubt this would give a good grip and examination of original Greenfield replacement linings for other models suggested they are made from dry cork.
I finally found some dry cork sheeting at spotlight of all places (in the flower arranging section). I'm a bit concerned about quality but was out of options. It seems ok but time will tell. If you find a better source, let me know.
I used a good quality contact adhesive. Best quality. Set the clutch up on a flat surface and weighted it for a day to get a good bond. Thoroughly clean the alloy with acetone and scotchbrite first.
Hope this helps,
