Re: 770 selectamatic lift capacity with pallet tines on linkage

I regularly carry approximately 10 cwt in a lift box with a 780 on level ground. The hydraulics are more than capable but front weights would definitely be required for more than this.

Re: 885 Engine Rear Crank Seal

There are two types of seal holders. The later one has an extra retaining bolt but the actual rope seal is the same for both. Copper washers should also be used on the retaining bolts. It is the rope seal that is renewed not the retainer.

Re: 885 Engine Rear Crank Seal

The seal retainer assembly can be taken out once the flywheel has been removed. There is a set procedure for installing new seals.

Re: 880 implematic cork crank seals

The seals fit over the lip— flush with the outer face of the casting. They protruding above the frame about 1/8 ‘’. Do not trim, they are the correct length. Use a non setting jointing compound. A wooden dummy cap can be used the hold the seals in place until the compound sets . Use guide bolts suit...

Re: Red 880 Selectamatics

I am trying to contact the present owner of this tractor and hopefully I will get the serial number. It may well be a little older than what I thought (1964) I remember seeing the tractor when it was new, there were two in Wales. It was in all probability used for demonstration purposes prior to reg...

Re: Red 880 Selectamatics

AFO416C Or the other similar tractors were not used in trials. They were absolutely new. The DVLA record is not exactly correct, it has the date of first registration as Jan 1965 and the year of manufacture as 1965. I think these tractors appeared around September/October 1965

Re: Red 880 Selectamatics

I know the location of the red Selectamatic tractor but I do not know the serial number. I would think the serial number would be at the very beginning of the Selectamatic range not the end of the Implematics.
There are a few imposters around

Re: David Brown 950 clutch problem

There is a scribed line on the mounting flange of the fuel injector pump that lines up with a line on the timing case back plate. Check this before removing the pump so that the pump can be refitted in the same position. The pump is driven by a short shaft that has a master spline so that the pump c...

Re: 880 oil leak

If you have an oil leak from the lift lock the cover and lift lock assembly has to be removed and a new ‘O’ ring fitted to the latch pin. If the leak is behind the ram cylinder, the ramshaft and ram cylinder has to be removed and a new gasket fitted. Could you please determine exactly where the oil ...

Re: 780 selectamatic air lock

It was the metering valve I had in mind when I said leave the stop control in the running position when the tractor was not being used.

Re: Left and Right Handed Pinion Shafts

On some Selectamatic models reduction units can be assembled as either right or left hand using the same parts.
