LK 3054 PTO Cluch

Jimmyb33 · Apr 28, 2010

I let a buddy borrow my Lk 3054 to do some brush hogging and when he brought it back, it had developed a problem. When I engage the PTO with the lever, It automatically starts spinning even with the cluch completly compressed. I hope there is a way to adjust the clutch linkage so that it works properly, but I'm not sure how to approach it. I guessed he had bent some of the linkage under the tractor when using it but have not been able to find anything that looks out of whack.

Thanks for any help here...

The PTO on my 3054 does the same thing. Gets a little hairy when
digging holes with the PHD.

Could just be an adjustment. You should have 3/4" to 1" of free play in the clutch pedal. If not, loosen the lock nut on the clutch linkage rod and adjust the pedal to 3/4".

Thanks for the reply. I didn't get a chance to get out there this weekend but will try one evening this week to check it out. That info will give me a target to shoot for vs. me just tinkering with it until I make it better (or worse)...
Thanks!

So what did it end up being that caused the problems

Jimmyb33 · May 12, 2010

I still haven't made it out there with a wrench yet. I did eye-ball check the free play on the ckutch peddal and it looks like a little over an inch... maybe 1.5 inches. I'm going to try to do some brush hogging this weekend and will make the adjustment to the linckage before I get going. I'll report back what I find.

If an older LK3054 (non-XS) it probably needs the clutch gap reset.
Pull the little side cover off, just above the hydraulic dist block.
Look for the head of a bolt sticking out like it is loose it will be nestled into a notch cut out ....there will be 3 of them.
They are for the free play on the traveling Pressure plate.
They should be set at around .028
You will be setting the gap between the PP and the bottom of the head of the bolt.
You will have to roll the motor over as they are 120 off of each other.
I believe these are either 14mm.
Normally they are very loose. Tighten them to .028 you will have to hold the flywheel while tightening them.
Then set the pedal free play as MIE stated.

I see it is a 199 so the above procedure should fix you up.

Thanks BTI for that info. I'll deffinately have a look at them before I adjust the linkage. Is there anyway you (or anyone else) can upload a picture of the cover plate showing it's location? That would be a huge help. Also, just to be clear, the gap is to be set at 0.028" correct? ...not 0.028mm.. (I know very small but I have to ask.)

Thanks!

Yep .028......SAE LOL
Sorry I have no picture to upload.

The plate is directly below the throttle lever, on the bellhousing.
It has the diagram for the hydraulic splitter on it unless it was powerwashed off.
It's held on by 2 bolts with 12mm heads.
It is approx 3" or 4" tall

Thanks BTI!!! I was just sitting here digging through the owner's manual and shop manual looking for that plate! I was out looking on the tractor 15 minuets ago and didn't see anything I thought would be that plate. I did see the plate with the diagram on it and thought it might be the one. Now, with your help, I know what to do. Thanks for the help! If is't not a wash out here this weekend, I'll try to get out there and get it fixed!

Ok, Here's where I am on this. I cracked open the plate today to have a look. It didn't take me long to figure out I didn't know what I was looking at. I could see a bolt but couldn't tell if it was the one I needed to adjust or not. It was backed out close to 1/4". Could this be one of the three I need to adjust? Is there any way I am looking at the wrong bolt? There sure isn't much room to work in there!! Thanks for the help!

I haven't been brush hogging since I bent my PTO shaft last fall so I'm just now looking at this problem again.

I had a chance to try to find the adjustmend bolts again this past weekend but ended up giving up before I could do any damage.

Here is a great pic by member Ohming that I think will help me out. Is it the bolts I've circled in red or green that need to be adjusted to 0.028" clearance?? I'm pretty sure it's not the ones I've circled in blue, but correct me if I'm wrong there.

And just to confirm, I should be able to adjust them through the port shown in the other pic? Right??

Thanks for the help.

Cant verify the clearance as I'm at home not at the shop, but the bolt circled in red is where you want it, this gap is what allows the main clutch to disengage before the PTO clutch, giving the 2 stages. I believe the 2 in blue are just nuts on studs used to help align the clutch to the flywheel, they are in the same circle as the mounting bolts. these should be tight. the three bolts on the fingers are to set the gap between the throw out bearing and the fingers and all 3 must be at the same height so all three will engage at the same time. Again, I have not books, and I don't turn the wrenches anymore at my shop, so I don't know the gaps.

Jimmyb33 · Mar 30, 2011

Thanks! Now that I know exaxtly what I am looking for I should be able to get this thing adjusted correctly.

As per the workshop manual, the clearance between the bolt head and the plate cover is 0.95 to 1.00mm or 0.037 to 0.039 inch

Jimmyb33 · Apr 11, 2011

Ok. Here's where I am on this one. I was able to find the right bolts to adjust. On the first one, I was able to tighten it down to almost 1mm. This one turned fairly easy until it got to the 1mm gap then it wouldn't turn anymore. I couldn't get the other two bolts to turn at all. I was able to loosen them, but when I tried to tighten them, theu wouldn't budge. I was afraid I was going to bust the heads off of these two. I have about a 3mm (1/8") gap on these two bolts. Any suggestions on how I can finish up this little job?? Am I doing something wrong??

Thanks!

Did you release the lock/jam nut on the adjusting bolts? The repair manual shows a lock/jam nut between the plates; it rests on the PTO, or bottom(inner)plate

Jimmyb33 · Apr 11, 2011

No, I did not release any lock/jam nut. Can you give me a better idea where it is? Ca I see/access it from the small access port? Thanks for the help!

Don't know? Am going by workshop manual and parts manual, as I've not had to address this issue myself. Both manuals show a jam nut between the travel plate and the PTO plate(by plate I'm meaning pressure plates), not clutch discs, although they're in the mix also. Going back to the workshop manual, I'm not even sure this adjustment is possible without splitting:graphics show the clutch units bolted to the flywheel and state (Clearance between traveling pressure plate and adjusting screw;
1. Measure the clearance between traveling plate and the bottom of adjusting screw with a feeler gauge
2. If the clearance is not within the factory specs, loosen the lock nut and rotate adjusting screw to adjust
3. After adjustment, tighten the lock nut firmly

Perhaps if you had someone depress the clutch pedal while you look into the inspection area at the assembly, you might be able to access the lock nut???? Wish I had more info for you; maybe e-mail Michigan Iron or other dealer for more info
