Mine is a 12xxx serial number. I have the top cover off in front of the shifter. It doesn't snap over center like it should and today I could hardly get it to move. Also kind of oily around the clutch. There is sort of a hose I presume is for greasing the release bearing. I has been falling disengaged for probably the last 10 hours and I worked it pretty hard at it's last outing. I think I need to adjust it. I did a search here in the threads and found several that discussed it some but didn't have pictures and old attachments seemed to be long gone. If someone has an old thread with pictures along with some experienced advice on what to do to get it back to what it should be, I would greatly appreciate it. I live near Woodland, WA if anyone nearby might be willing to pointy talky and tell me more on my machine and offer some experienced sage advice.

Someone will time in with a picture. Easy way is loosen locking nut on the front of the collar turn collar clockwise and check
For overcentre latch when it snaps over and stays lock nut back up.
Try not to let the clutch load right up in a stall this will make adjustments more frequent.

Yes it is. Use the 4 pic.
The collar shown in the pics is NOT the one you adjust, you need to look towards the engine.
Engage clutch you will get a better view.
You will see 4 levers that engage the clutch plate.
You need t.o look for the locking bolt as shown in the pic.

Hi,
if you come in from underneath, thru the covered opening shown to the right of the drive shaft in your pics, you will be further forwards and in the area to access the adjuster bolt when it is turned to the correct orientation as described.

So if I have to go from the bottom, my shop which is pretty new to me has a service pit. Pretty old cement, will my D4 damage the cement much to drive it in over the pit to adjust the clutch? Seems like it would be vastly easier then trying to crawl under there in the dirt. Secondly the pushrod and yoke from the clutch lever? What if anything do I need to adjust with it, noticed there is also a spring and nut for adjustment on it in the photos. Is that for the clutch brake adjustment?

It'll leave light marks that may or may not go away with foot traffic if you don't turn. Easy way to prevent it is to just lay down boards for it to drive on

if you're worried about the concrete, lay down a couple 2x8's to drive on, or a some plywood, or even old tires or conveyor belting. if the machine doesn't have corks on the tracks it is less likely to damage the concrete, but it may make little pock marks under each grouser. if you turn the machine on the concrete it will definitely cause some marks. and driving it up over the edge of the concrete you will definitely want protection on the edge of the concrete, it always seems to chip the edges the worst.

You alreadythe top cover plate off so why not do it from there.
I always do mine from the top, easier if you have to do in the paddock.
I think from the bottom is only if you have a wet clutch.
And yours is the dry clutch arrangement.
I just used a 3/4 socket and long extension.

Today I took it on. I didn't use the pit and wished I had. Hardest part was getting the collar locknut loose. It was a bugger. My breaker bar wasn't long enough. Fought it and got it loose, then figuring out what to turn to adjust it, that it was merely rotating the assembly where I couldn't see what was going on under there very well. At first I had it too tight. I don't have the called for scale so I got it so it was a good firm snap over center which has to be better then it was where it wouldn't even hold over center hardly at all before. I also wiggled that cotter pin in the drain plug and probably got a quart of reasonably clean water out. Pretty sure it is rain water getting in from that top cover that had pretty much no gasket left. Also found some grease fittings I didn't know about and some adjusting bolts underneath I didn't know about either. Presume they are either brakes or steering clutch related. Haven't tested it yet. Later this week probably get a chance to run it.
