Re: Cropmaster 30C brake job

Here we go with a mystery. I relined the shoes the same way as the other side. Assembled the shoes to the diff and the cam is at rest meaning that the shoes are as close together as they can be and at the moment there is no rod on the arm to adjust the brakes up or down so the shoes are backed off a...

Re: Cropmaster 30C brake job

Had to really compress this pic a lot more for some reason so detail may be lost. Maybe tomorrow I can then lift the reduction box back into position and bolt it up and start re-assembly of the reduction gear and fit the new seal in place on the stub axle.

Re: Oil/water mix in gearbox again

Thanks for the replies. I will try the flushing out using some diesel and hopefully that will get rid of the bad oil. Washing doesn't happen ever, I just brush over it with a broom at the moment as the paint work is in poor faded condition and I actually don't mind the look of it being in working cl...

Re: DB995 starter

This may sound silly but starting (no pun intended) with the real basics sometimes helps as we tend to over look them. Thoroughly clean both battery terminals and cable ends. Clean your earth straps and bolts and ensure they are making good contact. Even the starter switch terminals could be an issu...

Re: Cropmaster engine knock, petrol tvo

To save you from a divorce case chop a short length of garden hose off to do the same. Direct the end of the hose at the parts and it soon becomes crystal clear where the noise is coming from.
The sound you are talking about is clearly heard on your YouTube video.

Re: Oil/water mix in gearbox again

Thanks for the replies, I have already put the felt washer around the dipstick but failed to mention about the sealant around the split in the dipstick so that is an unlikely place of entry. Weather here is from an almost and only sometimes zero up to high 30"C and sometimes mid 40"C. So the idea of...

Re: Road speed

I fitted larger diameter tyres on the 30C so that I can use a lesser rev and do the same speed. Not big changes but enough when doing a trek. It did add about 4 k/hr to top speed.

Oil/water mix in gearbox again

Hi guys, I am looking for a reason as to why I have water in the oil in our gearbox again on our 30C David Brown. When we bought the tractor it did have water in the oil and so we drained the gearbox and diff and cleaned the brass filter in the bottom of the box. Then I found some tight fitting rubb...

2 David Browns

Last weekend we went over to the Gloucester Show Day about an hour inland from us in NSW. Unfortunately we could not take our 30C due to ongoing brake and other repairs prior to preparation for paint. So we took our Lorry with a Grey Fergy & plough followed by our van but there was a couple of respe...

Re: 990a crankcase pressure

I feel it is better to keep the one you know all about as to buying another one that you will possibly have to start from scratch to find its real condition. When doing our 30C engine I put #1 piston on TDC and marked the timing gears using a centre punch as the single dot on one gear never aligned ...

Re: Bent/Broken Push Rods

As it has been said that brass, bronze or phosphorous bronze guides are not commonly used in Europe and UK but bronze of some description is here in Australia in the car industry but not so much in tractors for what ever reason.

Glad your tractor now runs as designed
