Re: David Brown 950 clutch problem

I would think you will have to remove the timing cover so you can time the pump correctly ,

Re: 880 Implematic cracked block and head issues

That shaft looks good to me , if it was worn it would be easily seen as it would be out of true round.

Re: Cropmaster and 950 block

I would think not, there would be more bolts holding the head on a 950, there may bo other differences as well.

Re: 990 PTO power

The 20 spline shaft is 1 3/4" diameter, it is really popular here now as farmers are using high HP tractors on grain carts and big augers and other machines, you see them advertised on auctions as "big shaft 1000 pto"

Re: 990 PTO power

540 RPM is likely the correct speed, a 990 only has a 540 speed shaft , and if your brush hog fits that shaft then it was designed for 540 RPM.
unless someone has changed the yoke end and that is unlikely.

Re: David Brown 850 final drive

the diff lock should be held down not up . down pushes the collar onto the inner shaft so it cannot fall off. tie the pedal down with a piece of wire to the foot plate.

Re: 780 Final Drives.

if you look underneath you should see another hole , it is a drain hole for any oil that might leak into the brake drums . the reason for the top hole is ,left and right housings are the same , the side that is top on the left would be on the bottom on the right.

Re: I just bought what?

The switch on the bottom of the pto housing is a vacuum switch for the hydraulic pump it is connected to the orange light on the dash, I don't think these switch's are available anymore,

Re: I just bought what?

The pin hole is 1". Any drawbar you can drill yourself will be too soft an bend when in use, better try getting one from a breaker.
