never had this happen to a 430 BEFORE

Did My Sunday morning tour looking over the animals and crops ,fences.. got back to the barn and
the 430 went " click " and began rolling backwards down the grade ? , tried the Hand clutch ,no
difference ? No Change in the 3 pt ,It lifts just fine ? Tried All ranges they shifted easily with
little grind even with foot clutch not being depressed, the engine clutch flywheel makes its
normal sounds when engaged and disengaged ,,..i wonder if the main shaft snapped in the
transmission that carrys the power to the rear wheels beyond the triple range,.. btw ,.. this 430
has probably plowed to the moon and back 3 times in its lifetime

Does the PTO run?

Joe
 
Yes Joe ,It Does turn with the engine running and there is no slippage with engine off trying to
crank engine thru
PTO.
the trouble must be in the triple range pack I am thinking ?. No doubt ,This will require tractor
split ,,.. will that be at bellhousing ? or right before 4speed gearbox ?
 
Well as am sure you know the main drive shaft runs directly from the engine clutch friction plate to the PTO, the hand clutch for power to the transmission via the triple range gear train is PTO off the main drive shaft.

The fact that the triple range shifts w/o grinding with the engine clutch & hand clutch engaged points to no output from the hand clutch although we know that the hand clutch has input from the main drive shaft as the pto runs normal. The hydraulic pump drives off a separate shaft that is splined to the pressure plate which is bolted to the flywheel so it is not a consideration here.

That is just how I read your post although I may be missing something.

Joe
 
I missed that last, if necessary the split to remove the triple range or hand clutch would occur in front of the transmission.

I think I would drain the torque tube and get a good look at the hand clutch see if it engaging properly and to the input gear to the triple range gear train.

(quoted from post at 17:43:26 06/28/20) The Clutch pack feels normal when engaging and disengaging It has the Same snap as before .i dont think the half moon key is sheared off from the hand clutch. i fear a sheared off clutch pack basket " excuse my term"

Maybe jack up a rear wheel and see what turns as engaging in turn going forward to the hand clutch.

Also a magnet check of the torque tube bottom might turn up a clue.

Joe
 
Good idea , Joe , Been visiting family today . one Idea came forward same as yours , Perhaps the
Differential gear failed ?? 1st thing monday,i will remove triple range cover and see if i can
detect any failure there , if all OK then i will jack up both wheels to see if the other moves
opposite direction when i spin the other . That Will prove a Broken Spider gear which has occurred
on My Dads 430 about 1983. Sara and I Sure Do appreciate You stepping up with all your caring
thoughts . BTW , This 430 has a working traction lock pedal . just as a afterthought I will try
engaging that . But Dont know what I could discern after the test result.
 
Well ..the hub the hand clutch plates work in has come loose from the shaft,. Dont Look To
serious
If I can pull off the hydraulic pump and replace a woodruff Key that would be great . If Not? It
Looks like I am Gonna have to split this little fella apart. Any Ideas and Thoughts are
Appreciated.

I haven't found the hand clutch on the Caseih parts site, is it there? Do you have a 430 manual that shows how the hand clutch is mounted. I don't see how the hub can be loose if neither the main shaft or the PTO shaft is not broken but we have normal PTO rotation right? The hub turns on a brass bushing when disengaged while the transmission drive part of the cub is stationary. I suppose that bushing could be totally wiped out but then the hub has some support by the main shaft bearing pretty close in front of the hub.

I don't know that this will apply to your 430, so keep that in mind. The rest of this is hand clutch in 300,300B & some but not all x00B tractors. There is nothing you can do to the clutch hub on the pump side of the torque tube, there is no woodruff key or any other fastener. The hub is female splined and just slides on the male splined main drive shaft. The clutch has to be removed and then the hub just slides back off the main shaft if it didn't come off with the rest of the clutch.

Again this is the description of the hand clutch in 300,300B & some but not all x00B tractors, 430 may be different. I have a hand clutch off a x00B tractor, I can it take apart and get some pics if it will help.

I screwed up this sentence.

The hub turns on a brass bushing when disengaged while the transmission drive part of the cub is stationary.

Should read: The hub turns on a brass bushing when disengaged while the transmission drive part of the clutch is stationary.

(quoted from post at 04:38:38 06/30/20) Thank You Joe ,,. I have studied your post last week about the 300 hand clutch , the
430 should be the same animal ,. no need to dig deeper until i post again with more
findings. I will post a update.

Ok, if it is the same clutch, which I believe it is, there is nothing you can do with it on the pump side of the torque tube. It's a pretty hefty lift to pull all the removals to get the pump out also.
