L2800 HST PTO Troubles

[Racrx]

I have a 2007 L2800 HST

The tractor has just shy of 2500 hours, bought new and used alot. it has cut hay (JD 1217 haybine) baled hay (JD 14T & 336), cut grass (woods 3 point 60"finish mower) and run brush hog.

I believe my PTO clutches are used up! when I engage my mower the PTO speed will start up ok but will slow down drastically intermittently, but the tractor rpm stays the same.

I changed the hydraulic pump but this made no difference in the PTO performance.
I do get the PTO "chatter" with the finish mower, i used to only get it with the baler and haybine.

I think it is the over-ride clutches but after some research it appears my tractor may have the new design of the over-ide clutches since it is an 07?, if so I am wondering if there may be something else that is worn out?

Also an additional issue is the tractor is driving very slow, like 3mph, the new pump helped a little (up to 5 mph) but no where the speed it had when it was new.

The Serial number break for locking cams; for L2800DT/HST - serial number 57745-up; L3400 was 61733

Are you above that?? It doesn't really go by "years"...

You said PTO "chatter"; my guess it's the Cams... You would be the first I've heard about needing a PTO clutch job!

Let me know, I can post what another member bought to change out his PTO cams, I've seen the price for $45 a long time ago, I bought my set for $112 and for fun, I just looked up the current price, $154...

I have not done mine... had plan to do it last winter. Looking at next winter time project.

My serial is 61545

would the cams effect the speed of the tractor?

You have a fried clutch disk or pressure plate!

Who told you the hydraulic pump had anything to do with the PTO operation?

No... You planning to replace your clutch yourself?

No... You planning to replace your clutch yourself?

yes going to replace myself, any tips?

 

[old and tired]

Nope, just hoping to learn if you do it. Maybe Lugbolt will comment, he's very knowledgeable...

Replace the pressure plate, the clutch disk, the throwout bearing and the pilot bearing / bushing while your in there.

I think those are just the clutch fingers if I am not mistaken. That doesn't really show the wear surfaces very well to know if they are worn or in spec.

Looks like things got a little hot in there. How does the flywheel look?

I like the large arrow telling you which way to move the rear half! Don’t forget to turn it around during re-assembly!
(just joking with you so please take it as a joke not an insult as many people would)

My only question now is do I replace the PTO cam clutches while the tractor is split? according to the serial numbers i already have the updated clutches.

Flywheel looks good

I frankly don't know how the new cams even work... but not sure where you would get your "chatter" from otherwise.

Not the worst but slightly nicked up... Are you replacing them or leaving them?

Someone asked a long time ago about re-surfacing them? No one had an answer to that...

One guy who changed his out had a problem with lining up some gears, his solution was wrapping a thin string around the gear so that he could rotate it when putting it back together. (just in case that happens to you, too)
