    I've got old machines..three Cats..but none have sintered bronze clutch plates although the D7 has a sintered clutch brake. I had a tractor with a sintered clutch plate which I replaced with organic as it was too harsh on the flywheel and pressure plate.

    G’day Bigbjorn,
    The machine is a early ‘60s FIAT 50Ci,and it is the steering clutch X2 that I am concerned with.
    as you can understand I have had a few farm and bush ‘rebuild’, and now have used up my supply of the fibre plates.
    many years ago a heavy equipment fitter mentioned the bronze plates, and I am now thinking about them ; no doubt expensive, I haven’t checked on any availability yet as the spare parts/dismantlers I know of are phone enquires only and I have only just been told by my nephew in the Huon, that trouble is afoot.

    To 674 , I believe you are in Tassie, we must get together and talk Cats one day.

    How sentimentally attached to it are you? I worked for a while at Tutt Bryant who sold Fiat-Allis. We regarded the Fiat aggy crawlers as obsolete junk and would not trade them in. My memory tells me that the last AT7's were sold in Australia in the late 1970's and were almost worthless by the mid-eighties. Unless it is a hobby machine I would not spend serious money on it.

    Well I suppose in the cold hard light of day it is a hobby machine, although I did push in some critical breaks a couple of summers ago in the Huon, as a true sapper I was in the bush and gone many chains whilst the big time contractors where still getting dressed in hi vis.

    i haven’t priced anything yet, a real conundrum old gear; no good sitting in the sawmill; but I have to be aware of costs.

    In my banking career we did business with Tutt Bryant, and we financed a few of those Fiat Crawlers, and at one stage we repossessed one, can't remember the model but I seem to remember a number "25" somewhere. Anyway, nobody wanted it, but eventually we sold it for what we could get, & a regional Victorian "wheeler & dealer" bought it for his own use, clearing his property etc, he had it for years, virtually no problems at all!!

    My next door neighbour used a 70CI for over thirty years, and considered it quite successful. Used for clearing, soil conservation earthworks and dam and road building. I did drive it occasionally, including on one occasion for firefighting. Replaced by TD30 because he wanted a bigger one. A lot more problems with it. (Neither were bought new!)

    He got his parts from GW Tractors in Melbourne. No idea if they are still in business.

    We had a Fiat 50 on our farm for years. Petrol pilot motor, cable blade with winch at rear and cable up and over the top. Needed 10 arms to drive it (or it felt like that as a kid). It originally had a steering wheel to operate the steering (from memory) but we converted it to turn levers. We later upgraded to a Fiat 60 (or 70) with key start and hydraulics, LUXURY!

    My uncle rebuilt at least 3 of them, including our 2. I could ask him about clutches if you wished?

    The old Dad had a Fiat 25c ,equiped with blade and 3pl and p.t.o. ,worked for years, the only concern was all the spanners he bought in NZ with his deferred military pay, where ex US Army ,( wonderful tools ,I still use them) ,and.... all you old greasers and stockers and fitters will know where this is going, the poor old boy had to invest in some metric stuff.

    He sold it to an orchardist, and I think he still has it .

    A few 70s around southern Tassie , but like mine mostly just hobby work ,although that big ,slow revving engine just keeps chugging along , my 50 gets max. torque at 800 r.p.m..and 1gallon hour with offset discs.

    John ,your friends TD30 was a giant in its day, with planetary steering and big h.p., we had two in the bush in N.W. Tassie , with a little tin plate on the bulkhead stamped S.M.A.
