I changed the filters, the one in the trans was dirty on the outside so I am assuming it was worst on the inside, I got it running, put it in forward, low, and it moved 25 feet and started slopping and chattering, and stopped, then reverse, it wanted to go like there was no trouble, went for about 200 feet or so in reverse and then the same shuttering almost feels like something loose, thats a description of what it feels like befor eit stops, I was able to go forward another 35 feet or so and now nothing, I cant get even a inch out of it, but I have not tried it again since it cooled down abit, even though it was not that warm when it stopped, one thing I dont get on the fotN iinch valve , in the book it says that it should have 9/16" travel between the stop and the valve, mine has no travel its just seems solid when moved, I havent really tried to adjust it yet , becasue I want to do a little more research or hear from someone what to look for,thansk I am sure it is a simple adjustment, but I should start there I was t old, thanksk pat

Pat,

If that thing will move that far it is not all that serious.

The first thing tho, you just gotta get that "clutch" valve to shut. Heck with the free travel for now. Just make darned sure the pedal is pushing the valve clear closed when the pedal is "up".

Then try 'er again just using the hand control. If it still doesn't work right, we've got to decide if the problem is upstairs in the shift control or downstairs in the unit.

Pull the battery cover. You will see two capsules staring you in the face above the battery. One is an anti cost valve and the other is a check valve. They are not the same, but we can switch 'em just for a quick test. Be sure you keep 'em straight in your mind so you can switch 'em back to their proper location.

Let us know where you are at that point. If it works "kinda okay, but not quite, you've found the problem and it needs the two capsules.

But, if the "hot and cold" shudder thing is still going on, we gotta go downstairs in the unit, but it is no big deal.

Allan

hello allen, I am not sure if this is too far down the list to see, but I got the foot n inch valve closed, and changedthe 2 capsules, no difference in operation, I took the side panel off on the left side , it has 6 bolts holding it on, I can see where the S R goes from forward to reverse with it off, On the inside of there it appears to be a plate that moves when the SR is moved, is this like a clutch plate sort of, because i see there are two pistons that appear to be able to ride on there , maybe if there is pressure applied from the other side, are these supposed to be loose until pressure applies to the plate? what next?? pat

The more you talk about this "hot and shudder" thing, I really think you need check valves, but let's try the capsule trick first.

They are a heck of a lot easier to fix. :>)
