Case International 885XL Gear Linkage

[gadzooks]

Mine has the two-speed power shift transmission with 16 forward and 8 reverse gears

1, 2, 3 and 4 low forward (tortoise)
1, 2, 3 and 4 low forward (hare)
1, 2, 3 and 4 high forward (tortoise)
1, 2, 3 and 4 high forward (hare)
1, 2, 3 and 4 reverse (tortoise)
1, 2, 3 and 4 reverse (hare)

The problem on mine's with the left hand lever ('range', it seems it's not a 4-way H pattern, its actually just low to forward left, reverse to rear left, and high to forward right). Apparently 'this lever is linked to the hydraulic spool in the Forward-Reverse clutch housing.'

So perhaps in my case I shouldn't be looking at the 2 sets of linkages on top of the gearbox, as they seem to relate to the 4-speed shift lever which isn't where my own problem is..

'this lever is linked to the hydraulic spool in the Forward-Reverse clutch housing.' ... is there a possibility low oil could be the cause of my own problem?

I fear I'm derailing the thread from the OP's topic a bit, here. I should maybe start a different thread?

Thanks Milkloss that's extremely helpful in helping me understand the speed linkages, just what I'd hoped for. If the problem does exist in those links after all I now have a clearer idea.

Power shift? Far too modern for me then!

Milk loss is on the money gear linkages for sure 100% go under tractor and wiggle until you get it into neutral block the wheels in case you run yourself over it may help to have somebody in the cab holding clutch down

 

[gadzooks]

I have no idea if that makes sense!

- Slept on it & yep, it does, I have a good solid idea how its supposed to work now.. thanks

All that side of things does feel like it's working ok though. Going to go out now it's dry and light & see if I can verify those plates are really engaging and disengaging as they should on the right hand speeds lever. Maybe 'feel' alone doesn't show up something not pulling out when it should.

Would you happen to have a similar diagram but, for the left, range/reverse lever mechanism?

No I don’t. The one I posted was surprisingly hard to find on Google. I have a feeling the mechanism is essentially the same and we had a wire around the quadrant shaped plate to pull it out of high and into neutral. I wasn’t present when it had a better bodge but I believe it involved wheel off and building up the mechanism with weld.

The gate/slots/H etc is worn, common practice on these, you need to build up with weld or plate to form the H,

If you hadn't found that diagram I wouldn't have known quite what I was looking at, grateful in the extreme for that

The mechanism for the left lever works in an extremely similar manner.

Turns out, if you have the wheel turned just right, you can see through the side quite well with a decent torch.

Attached string to the lever and pulled on it whilst looking through wheel, the connected levers became immediately apparent.

The whole mechanism is wobbling all over the place. The fore-and-aft pivot seems to be entirely missing a bolt. Looks about a 13mm head size, not sure if it's just a standard bolt or some kind of specially shaped part.

New bolt should fix it & hopefully not too hard, if I can figure out the right size.

I'm sure the gate/slots etc are indeed worn as well, as the action was never fantastic, but hopefully a bolt might get it at least going again

 

[gadzooks]

For completeness & to help anyone comes searching, a fresh M10 bolt about 50mm or so long in that hole, followed by jiggling the 2 gate/interlock plates behind it, fixed the problem and released it from low forward range. Got all the gears back now. Thanks a million for your help guys.

Sorry for the repost, came back to the thread once again just in case some poor sod in the future struggles like i did lol

Fixed? Yeah for 10 minutes. Few weeks later, same thing straightaway.

Takeaways:

1. The guy who said, tie a cord to the plate and run it up into the cab as an 'emergency releaser', wish I'd taken heed when I has the wheel off.

2. If it's all in bits, take the trouble to repair the wear in the plates while it's easy, you won't regret

3. On mine, it's the inner plate needs moving 'front end up' to release. If you're lucky and the rear wheel stops in the right position, you can insert a long stick of some sort right through the hole in the wheel, pass it under the pushrod that connects to the front end of the inner plate, hook it up on a bit of chassis and lever the pushrod up. Click, and all's free.

My 585 l cab has been stuck in low for 5 yrs , have a bar I use to select high .ime guessing it's linkage issue
