Re: 885 overheating

Have you looked in the radiator as the water warms, do not remove the cap when the water is boiling, to see if there is turbulence as the pump works. If none then they may be a blockage, thermostat fault or pump failure.

We sold Claas rollants back in the 80's which worked well with DB's.

Re: New 885 brake pads not fitting in drum

I am sure you will have checked this but the outer lip of the drum, where the brake shoes don't contact, can get heavily rusted over the years. This often needs to be removed before the new shoes will fit.

Re: First time start after rebuild selectamatic 780

You need to check the circlip on the injector pump drive shaft/gear is in place. If this is missing the shaft can slip down far enough to pump the timing out far enough not to start. With the pump off you should see the circlip holding the shaft.

Re: Steering arm and or ball joint remval

You will need to replace and tighten the steering box bolts before you try the 'shock' method or the 'shock' will be absorbed also you may damage something.

Re: 885 Steering column - Bearings on worm

It would remove all risk but if you adhere to my previous post you will save time removing the complete steering box.

Re: 885 Steering column - Bearings on worm

If you remove the four bolts at the bottom of the column and let it drop back there will be enough room to remove the dash BUT DON'T TURN THE STEERING WHEEL or the balls will drop out. I have done this many times without any problems.

Re: 1294 Roof electrics dead.

The join is inside the cab frame on the r/h side where the top half is fastened to the lower half, so not easy to get at. It would a good idea to check the feed wire is live before entering the frame but not at the roof before thinking about the connector and if it's the problem thread another feed ...

Re: Hydraulic filter on fitting problem on 990

I had this problem with a vapormatic filter a little while ago it was just poorly made and went back. I finished up with a Sparex one and it fitted perfectly.

Re: 1594 trailer brake valve

Scan_20180120.jpg Don't fully understand your post, have you been using the tractor without brakes for years? If you disconnected the brake line from the trailer brake valve you should have blanked it off and sealed the inlet to the brake valve. I should think the seal (see attached service bulleti...

Re: Problem splitting 995

Good ideas from Gard but chances are the PTO shaft is either stuck in the plate or pilot bearing. The movement you have is the PTO shaft sliding out the input shaft until it contacts the crown wheel. Try and get some penetrating fluid squirted into the clutch centre.

Re: Rear main seal for AD4/47 engine

There was no 'rope' seal, the idea of the scroll was that as the crank turned the scroll would return the oil back into the engine. As you say you cannot fit the rope into that unit so you need to fit a complete seal housing if you go for a rope seal.
