Re: DB885 Serial Number Location

On some of the 885 tractors the serial number is stamped on top the frame near the bottom radiator hose.

Re: DB885 Serial Number Location

The wing nut on the side of the pump has to be turned in before any attempt to start the engine - if the engine is rotated before this device is engaged, it does not function. Is the Thermostart heating up ? When were the fuel injectors last serviced?

Re: DB885 Serial Number Location

The DB three cylinder engine is normally an excellent starter.
Are you operating the cold start procedures correctly?

Re: 885 PTO Engagement

Be aware that if the clutch requires adjusting as described it indicates that the TRANSMISSION PLATE has worn down to approximately its minimum thickness and requires replacing. If adjusted the plate will continue to wear down through the rivets until it destructs, usually requiring a complete new,e...

I used to syphon the fuel out using a large syringe or an airline to start the process.

Re: New member 1952 cropmaster

Driving a small topper would not be a problem in my opinion. There could be a problem with the hydraulic system lifting capabilities. The hydraulic pump is old and new ones are not available.

Re: Rear Wheel sizes

Your tractor would have had 32 inch tyres when new. The DBTC has an arrangement for club members with The British Rubber Co ( britishrubber.co.uk ) They have the tyres you require.

Re: New member 1952 cropmaster

I personally use batteymegastore.co.uk Most people use the largest 12 volt battery that will fit in the battery carrier in place of two 6 volts. You can still obtain 6 volt batteries but they are expensive and most of them are of dubious quality. To keep the original look you can use dovetailed wood...

Re: Lift pump dropping fuel

Can you please give the tractor model.
If the valves in the lift pump are defective the fuel can return to the fuel tank if the tanks are under slung. The diaphragm can also be defective. If the pump is defective fuel can leak into the engine oil.

Re: 780 Cylinder head core plug

Puncture it in the centre and lever it out with a bar or strong screw driver. Clean the recess well and coat with jointing compound. Fit new core plug ( domed side out ) and then hit the centre of the plug to expand it. Mild steel plugs are perfectly ok and will last indefinitely if the antifreeze h...

Re: 780 Cylinder head core plug

Yes the diameter is one inch but the updated version I believe is stainless steel. I recommend fitting a stainless one and then you can forget about it.

Re: Steering Column Repair Kit

There are three bushes for the cross shaft,two large and one small. It is not possible to compensate for a worn shaft by making oversized large bushes. New steering nuts and steering screw shafts are available but not the cross shafts.
The column bearing is is a Dooble Row, S/A Ball, SKF.2304
