154 PTO Clutch bearing replacement

Postby seanthenry » Mon Jun 29, 2020 2:49 pm

I'm sure I just looked in the wrong service manual and searched for the wrong thing. I have the service/parts manual with the diagram but it does not talk about rebuilding this.

I need to replace the 3 bearings between the forward and rear pto cam and need a little guidance.

I have removed the PTO from the tractor I'm to lazy to remove the pulley from the shaft so that is still on(not that removing it would be a problem).
Can I remove a snap ring on the tractor side of the cam to pull the old bearings out? When putting the new ones in I assume they should go in the cups and line them up to match (currently they are all in different locations)?

It there anything I should look out for when doing this?

Background:
The PTO worked when the transmission got stuck between gears. After putting the trans in neutral to move the tractor I tried starting it and tested the PTO but it would not catch. I figure this was from the "fix" the po they lost the spring on the pto lever and used bailing wire and a hook they added to the fender to keep it in place. That bent the PTO control arm. I have a new control arm bearing and spring hopefully that will get it up an running.

If I remember correctly there’s three bearings one with double vee belts in the front, a bearing before the pto clutch, and one in the pto clutch. The pto engagement has bearings too. The years of the 154 are different but the same design. If it’s disengaging the pto lever the bearings inside the engagement pto levers are wornout.

I have three int154’s, one ran but the pto needed bearings, the third one needed a clutch. The second one is my fel/ backhoe project. My point is by the time we gettem there run hard with no maintenance. They are a dream to mow with, push snow with.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Yeah I'm looking to replace the three bearings to lock up the clutch, they would be the closest to the yellow part here. https://hamiltonbobs.com/cart/product/p ... -lo-boy-mm

I loved the summer I got to cut with it half the time I did not have a real throttle and now that I have replaced 90% of the wires the engine is so much smoother. Later I will replace the ignition system and clean the carb.

The 2 brgs that lockup the clutch are part # 84250089..from CNH. CIH has 30 of these on hand. These work on the two eccentric plates.

Thanks for the part number but I already have the 3 bearings to lock up the PTO clutch. I just want to know do I have to remove everything from one end of the clutch shaft till the plates are separated or can I do it as one piece?

I got a little time to work on it last night I was able to pop the old bearings out and shove the new ones in. If I move the pto leaver like I'm engaging the PTO then one pops back out. I'm thinking it is the spacer just before the cam (Part 34 Parts catalog P27) might be worn giving it to much space. It looks like I might be able to tighten the locknut but the set screw is stripped so I have to drill that out and replace the screw.
