Re: DB roses emblem - gold or silver outline

I think the gold versions were on the DB Non-Implematic tractors but I am not absolutely certain. New gold versions are not available.

Re: Stabilizer alternative needed.

Check chains are usually suited to ground engaging implements and stabiliser bars for non ground engagement equipment as explained in the tractors operating manuals.

Re: Cropmaster Loader

Very interesting— never seen one like that on a Cropmaster. It would be nice to know the manufacturer.

Re: 996 injector pump

The seal kits from Sparex are incomplete for DPA pumps on DB engines with a cold start device. www.davidbrownparts.com supply complete kits. Resealing the pump is one of those jobs that is easy for some and very difficult for others. The position of the governor linkages must be noted during dismant...

Re: Cropmaster lift piston rings

I support what Geoff has stated. I would be surprised if the valves in the pump are all sealing perfectly. If the tractor has a valve connected to the front of the cylinder for external services this can be used to isolate and test the cylinder after raising the rear linkage. There is a special banj...

Re: Cropmaster lift piston rings

The Cropmaster cylinder has pressure relief vents which could cause a problem long term with rubber type seals

Re: Cropmaster engine number

When you have the DVLA documents etc as proof you can obtain a new replacement plate with the numbers etched in. Trying to stamp the numbers yourself is a disaster. I have used this supplier for the above, with excellent results. www.vintagebrassplates.co.uk The plates on the market other than the ...

Re: Cropmaster engine number

Neither of them are the engine number, they are casting numbers. The engine number is usually be stamped either above the starter motor just under the rectangular cover plate or near where the oil filler tube enters the block. The number is stamped into the cylinder block Is the identification plate...

Re: Timing gears 25D; same as 850 /950?

Not many 30D tractors with that type of pump. It was introduced towards the end of production, same setup as the 25D. One from a 25D would fit but it would require calibrating for the larger engine

Re: Timing gears 25D; same as 850 /950?

Looking at the engine pictured I would say it is in all probability a 25D . There should be an engine number stamped in the block on the same side as the starter motor, either under the rear rectangular cam follower cover or near where the oil filler tube enters the block. Not many 30D engines have ...

Re: Timing gears 25D; same as 850 /950?

The chances of finding a 30D with a DPA rotary pump would be extremely unlikely as only a very small number were made for evacuation purposes. If the engine is modified a rotary pump from a 950 or 880 would be required, not an 850. The pistons should also be changed because the 30D with an inline pu...
