D8K steering

I think you should check the trans pump pressure, check at high and at low idle on both machines and compare. A good pump will hold 90% of high idle pressure at low idle. Check pressure at the priority valve on front of trans. I think a worn pump might cause the delay.

hello paul ,the d8k sounds ok to me 1 sec is ok ,wait till you are using it and it want turn with you pulling back and foot on the petal till your face goes red ,and then get her fixed ,lol, the d8k has a magnetic help on the clutch petal ,you can feel it pull in when you first put your foot on the petal ,that why never use petals for foot rest ,they will keep pulling onto the band wearing it out quicker , i operated a d8k that was 5yrs old and it wouldn't turn in heavy going towing a 100ft land-plane ,had to pump up the tracks every shift , you will know when its needs fixing ,bruce oz

On the K series tractor the brake pedals are only used when working on steep angles, so the adjustment is often over looked, so the best thing to do is adjust the brakes on both tractors, then compare the action.

Now don't laugh but I have been looking at the two brake peddles on the floor thinking. what are they for. One a brake but why two. So are the pedels for different sides?
I have been only stuffing around putting rakes on them so have not really had a good test yet but this machine has a new tran pump fitted prior to sale so it shouldn't be that. I have bought a manual but it has yet to arrive so I wouldn't have a clue on where to test pressure or make adjustment via the book.

Thanks for all the help though and I will have a closer look as soon as I get the book in.

best regards

Me again, Can someone send me the full brake adjustment procedure to save time before the manuals arrive. This with any other pearls of wisdom would be appreciated.

Paul, at the rear of each steering clutch cover is a triangular cover. Under them are the adjusters.
Tighten up all the way then back off 9 clicks, 1 1/2 turns.
Also make sure both peddals move freely. The RH one has a cross shaft in the linkage that tends to seize up.
I think steering linkage is done by removing pins from linkage.
Pull links forward untill rollers inside valve make contact.
adjust rodends untill pins slip in freely with links at shortest length while levers are at rest.
Then back off rodends 1 1/2 turns and lock up

The K's run two brake pedals because you can still disconnect the applacation of the brake and friction and operate it like an older tractor, where you have to pull the sterring clutch lever and step on a brake, the K's were the first to come out with this option I would call it of not haveing to step on the brake to turn, it applies it self when you pull a friction lever.

Arron, converting back to D8H system requires some new parts in the steering valve.
