Hi,
I noticed your postings regarding your deluxe cultimatic. I've got one and have been on a quest similar to the lord of the rings in an attempt to get the reverse pulley friction disk replaced. Basically, it can't be done. There may be some genuine parts languishing around somewhere, but not not on the internet. I narrowed it down to 3 likely places in the UK which keep old stuff like ours, but they didn't have any.
My friction disk was worn out and the V pulley was starting to eat through the pulley shaft.
I got some replacement discs from Chester Hudson in Sussex. They are not made for this operation, but should be do the job if you can machine a larger central hole and then file some flats on to it. You'll find Chester on his web site "Tillerparts.com" His phone number is also posted. He will supply 2 disks and post them for £11.
I've not finished getting my discs ready for fitting yet so I can't say if they work or not. However, they are made from brake lining substances so should do the job, and as far as I can tell by eye, they seem to be about the right diameter to fit straight in.
A word of caution: Neither Mr Hudson nor myself can tell if his discs contain asbestos or not, so if you go down this route, take all necessary precautions when machining them.
The disk is retained on the shaft with a circlip. As they are steel, your shaft and circlip should have survived a fire, at least enough to give you the dimensions to replace them if they need it. The shaft should have a grease nipple on the end to allow lubrication of the shaft which runs directly on a steel rod
The pulleys are all alloy as you have found out the hard way. I don't have the dimensions to hand as I've never measured them, and I'm not doing it just now as it's belting down with rain. But if you like, I can give you some measurements later if you want them. Let me know.
You can still buy both drive belts as a set on e-bay, believe it or not. If I remember correctly, the outside length of the main belt is 40". I can't remember the reverse belt length.
By the way, my machine is from 1977. Yours won't be too far either way from it. I do still have the owners manual which came with it somewhere, but I don't think it gives all the specifications of the parts - just a list of them, which is not much good now nobody has any.
Let me know if you want any more information. You can e-mail me direct on: mc31@york.ac.uk
All the best,
