Cropmaster generator

Another option is to convert to a 12volt generator. I found the C45 Lucas generator fitted without too much modification. Turned down the pulley shaft and cut a longer keyway and a small turning job allowed the Cav end plate to be fitted to the Lucas generator. You have to fit a new 12 v regulator a...

Stew

My tractor is on display at the Laidley Historical Village Tractor Museum about half way between Brisbane and Towoomba. I would be happy to meet you there when it suits so we can have a good look over it and run it up.

stew Well done getting the motor turning over. Here are some photos of the generator from my tractor. Ignore the generator end as I have grafted on a 12 volt Lucas generator back end in place of the 6 volt CAV unit but the gear drive and governor 'wings' are original. I have just converted mine to 1...

885 sender

Looking at the two side by side and noting what you say about the resistance being correct I was wondering whether you could cut down the diametre of the new sender to the same size as the old one? This might be better than changinging components? I declare my vested interest as we have been trying ...

Cropmaster Crank handle

After a long time looking here in Australia I have not been able to find a crank handle so i have decided to make one. Over the years I have been given two drawings. One says the handle is 5/8" (16mm) round bar and the other says 3/4" (19mm) round bar. Could someone who has the proper Croppy crank h...

who am I

As I noted back in Jan 2011 the serial number P45862 is for a first series 30C built between Mar 1953 and February 1954. The source for this is "The David Brown Story" by Allan Condie and John Melloy.

Oil pressure Cropmaster

Hmmm This seems very strange. My first thought is can we trust the gauge given the history of the tractor? Can you swap it temporarily for another gauge to eliminate this option? Next is the wire strainer on the base of the pump clean to allow oil to reach the pump? I note that you had the sump of s...

VAK1 Age

According to Condie and Melloy the first VAK1 was numbered 1001 in July 39 and the first and last tractors for 1940 were 1050 and 1999 respectively. So the date on the V5 sounds about right if you assume the tractor was manufactured a little before that. Nice early one you have there. We would love ...

Cropmaster on a trailer

Stewart According to the conversion I used the Cropmaster weighs 1500kg all up and without wheel weights. Normally you would need to be cautious as tractor tyres in Australia are usually half full of water and this weighs plenty but as your tractor is without wheels you dont need to worry about this...

Cropmaster Oil pressure

Stuart In my opinion 15/40 is very light for an old engine like this and so I suspect you will see some small improvement in the pressure. Certainly worn main bearings will be the main cause of low oil pressure. It could possibly be caused by worn rocker bushes as well. You can temporarily block the...
