Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

Might be best to start a seperate thread to sort out your cold start issues so it is not confuing as to the replies for each issue.
IF your ignition switch is not working correctly andnot making contact properly, this maybe the problem for the cold start.

Re: Cropmaster petrol to diesel

I think it would make the 30C lean over to one side if it was fitted. It really is one very industrial and heavy starter.

Re: Cropmaster petrol to diesel

WOW, how this got resurected from 2011 is amazing. The idea of converting a 30C to diesel left my head once I found a complete 30C, Series 1, Cropmaster style tractor. Since buying it I have done the lot on it rebuilt the engine, clutch, brakes, various bearings around the tractor and seals then fin...

Re: Purchased a Cropmaster - Have a few questions

Nice one Mark and thanks for the video links. Out here you can find the parts at a tractor wreckers, online auctions also can produce the oddest parts at times. Maybe a member on here might have a spare parts machine that they are happy to sell the flywheel and starter you will need. Then you will n...

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

Yes, very well done. As stated it appears that we should check the assembly against the workshop manual to be certain it was put together right the last time.

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

What great news that you have found the problem of the gears not meshing. Something that I have read about with hydraulic pumps is end float and this must be accurately measured and tolerances adjusted back to specs. One thing that can make the tolerances too big is wear on the end plate as fluid ca...

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

There has to be a reason for this issue. Are the other gears the correct ones and can they be fitted wrongly? It appears you have the right gearon the pump so now work backwards from there.

An interesting issue you have there for which I have no answer. Unless other gears are wrong or there is an optional gear that will make it engage

Re: flushing out transmission/Hydraulics

One of the tips for my tractor was to use diesel in the box and drive slowly around hitting the brakes and accelerating for a short time. Drain completely, maybe even doing it twice then if happy refill with new oil.

Re: DB 990A Implematic Hydraulics Not Working

BSF = British Standard Fine. BSW = British Standard Whitworth. Both are Whitworth threads and nuts and bolts can still be purchased but are expensive to buy here in Australia So I bought a small lathe to make ones myself. As for spanners, these are still available online and most are made in India. ...

Re: Cropmaster Clutch

When I fitted a new clutch assembly in my 30C I just put the old assembly on the counter, gave him the details of the tractor and he looked up the replacement assembly which too 2 days to get in. Complete assembly including the thrust bearing. Was not a hard thing to find here in Oz. I figured it wa...

Re: 885 retard screw

When oppr if I buy something that is "not running at the moment, but it was running when I parked it" I price them on scrap or spare parts value. The reason is that some people handle the truth very carelessly if you understand what I mean. If it ran all those years back and it was not seized anyone...
