821 CASE BRAKE QUESTIONS

[TVA]

These are your clusters, they actually less expensive options, not sure if those have indicator rods though. Should be in front half of the machine underneath and to the front of cabin floor. Might have to remove fenders to get to them.

This should help.

On the transmission I would start with electricals first. Switch and wires.

Here is indicator rod attached to the spring, you should see it moving when applying the breaks.

Resistance you feel is in the foot air valve ( probably E6). On the cluster ( that’s where air pusher bolts to master cylinder) there’s usually indicator rod - when air drum pushes the master cylinder you should see thin rod moving in and out. If it doesn’t - your problem is in the air half of the system. Does machine building up the air pressure? Usually gauge would have green field and say “drive”.

Hey,

I know it builds pressure because it releases some every so often. I don't think I have the green indicator light though, if I do it's possibly burned out? Then again I only had a few hours to run it and my two year old was on my lap the entire time.

 

[TVA]

It’s not a light, it is green field on your pressure gauge dial. If you don’t have air pressure your breaks won’t work.

I found a kit to rebuild the calipers for very cheap. Still have the problem with the transmission though. Haven't had time to look at it.

Thanks for any help.

Does the brake pedals move when you push on them? Is there brake fluid in the brake reservoir, on right side of machine near engine and transmission mounting area? On the transmission problem there could be two issues, the shift solenoid in trans control valve for first gear or the micro switch in the FnR shifter switch.

The front two calipers are the ones that would hang up frequently and thus are the ones in the picture that have the ridge. The back rotors are in very good shape. I think I'm going to order the rebuild kit and try one to see how it goes. Any advice on the shifting would be greatly appreciated. Thank you all for the help so far!

Hey, Thank you for responding. I didn't read what you had posted accidentally earlier. How do I go about testing the solenoid? How do I access the solenoid and the micro switch? I enjoy mechanics but my dad was always at the bar growing up so I'm not the best but I really like to try so thank you for all the help.

The solenoids are under item number 2 and you can check them with an ohm meter. They should all ohm out the same within 10-15 ohms anyway. Item #4 are the solenoids you are looking for.

Thank you! This will make everything much easier.

No problem: let me know what your reading are on the solenoids please.

4 of the 5 solenoids were at .08-.09. But the 3rd one down didn't read at all. Which makes sense because I think that would be the one that controls 2nd gear. Because the very top one I don't know what would do but the other 4 seem like they would control the individual gears and that makes sense because it doesn't shift to 2nd. Are all the solenoids the same? I thought of pulling a different one out and putting in place to test it. Titan Machinery said the solenoid is $850 and that seems ridiculous to me. DOES ANYONE KNOW OF A BETTER PRICE?

Hey Coy,

There wasn't any brake fluid in the resevoir. I think I'm going to flush the brake system out. I'll be taking off the one caliper that sticks and rebuilding it so it hopefully doesn't hang up anymore. I believe I figured out the shifting problem to with it being a bad solenoid. But Titan machinery wants $850 and that seems like highway robbery.

Quick search showed this:
But don’t take my word for it - verify! Pull solenoid out and read the numbers on the side. There’s couple of versions of that control, first you need to find which exactly is yours. Case P/n is 242137A1.

 

[TVA]

Also it might be wiring problem and not solenoid it self - verify before buying.
If there was no break fluid it means something was leaking! Another problem when system is empty for a long time - everything gets rusty because break fluid is hygroscopic and attract moisture.
So even if your air side is working ( which you haven’t verify yet) after you fill system with break fluid components would start leaking one by one!

TVA,

Thanks for the info! I could find that one on the 821B but not on the 821. I'll go out this morning and pull it out and check. Is removal as simple as pulling out the alan screw and pulling it out? Seems very simple. Thanks for the reply!

 

[TVA]

Yes, was wrong, your serial number is prior to 0025165, and your part number is S300553.
But still pull solenoid out and try to read numbers off of it and search!
Also try “Spicer powershift solenoid”
I never worked on your particular machine, but try locating the transmission name tag on the bottom of the transmission pan to see what model transmission is. Usually it’s Clark but later they was bought by DANA/Spicer so it might be Spicer. Although CNH like to get rid of original manufacturers name tags so they can make a killing on parts!
