Hey, I had a new clutch installed about 30,000km ago, on my international 9200i, with Isx, when I press the clutch all the way to the floor to engage the clutch brake, you can feel the pedal grab, it definitely feels like it's in the pedal, but maybe its misleading.
When you release it, the pedal grabs for a second and then the pedal pops out, and returns to the normal spot.
Jake's and cruise control all work, and pedal works fine, clutch brake works fine.
I have 1.5 inch free play and 1 inch at throw out bearing.
It feels like it's in the pedal area, would it be something like the spring? The spring does seem easy to push on, you can easily compress the spring with your fingers and it does move around alot.
Is the spring responsible for returning the clutch pedal when its fully compressed? I thought it was just more so the pedal went fully up?
Before I start pulling it apart, does this seem like the correct area?
Thanks

Most of the time there is about enough room to get a pencil in between throw out and pressure plate when it's adj. Correctly?
Another Canadian driver Thanks this. -
I Always use a 1/2 inch Drill bit when adjusting Mine..
@MTMAUS Is it a Cable or linkage setup??Another Canadian driver, Rideandrepair and spsauerland Thank this. -
To me it sounds like a linkage problem, like a bel crank overtraveling, or a bad angle in the linkage. 3/8” to 1/2” at the throw out should give you 3/4” to an 1” free play at the pedal. If I had to guess I’d say someone tried to adjust the clutch with the linkage at some point, and the new clutch and throw out drove an angle out somewhere as a result.Another Canadian driver, AModelCat, Rideandrepair and 5 others Thank this.

It's a linkage system.
What's the best way way to adjust the linkage? I think I saw 5-6 adjustment points, how do I find the culprit without messing up everything.Another Canadian driver Thanks this. -
I agree with all of the Above..Rideandrepair and BoxCarKidd Thank this. -
It's not an adjustment problem. Something is worn out.
When they put in the new clutch, did they also use all the parts in an install kit? Did they even use an install kit? It comes with a new fork, new bushings, new input shaft, ect.
Also, has this been going on the whole time, or just recently? You said they replaced the clutch 30,000 km ago. So did it start then, or recently? How often do you grease the fork bushings?black_dog106, Rideandrepair, BoxCarKidd and 2 others Thank this. -
Been years since I worked on a 9200i, but like most IH I believe the linkage joints are just clevis pins and holes drilled in brackets that get pretty worn out. I remember having to weld many holes shut and re-drill to get the slop out of our old 2674 Internationals. You want 1/2" between release bearing and clutch brake first, then set the 1/8" between fork and release bearing. I somewhat remember a clevis near the firewall that could be adjusted to compensate for some of the wear.

For it all to work right you have to find the correct at rest position of the belcranks in the linkage and make the rod lengths fit that. If everything is right in the linkage correct adjustment at the clutch should give you proper pedal travel and free play.haycarter and spsauerland Thank this.

There are grease fittings on both sides of the bell housing and on the bellcrank.
The one on the bellcrank get overlooked quite often. I like to use chain lube
on the clevis pins as well.Rideandrepair, spsauerland and God prefers Diesels Thank this.
