I got the PTO clutch off and started on removing the flywheel. Going to fab a puller as the one I normally use doesn't bolt up as well as I would like.

 

When you start to take the PTO clutch off make sure you remove both sets of set screws in the clutch housing, I almost missed that and Daniel put me on the right path.The second set holds the first set from backing off the shaft.

 

This engine was out in the weather for long time before I got it. So I soaked all the set screws overnight with PB blaster. I then got a needle nosed long punch that would fit inside the set screw and gave it 3 or 4 good taps with a hammer.

The set screw wouldn't budge so I used a small brazing tip on the torch to heat up the clutch housing.

As soon as I got done heating them up, they broke loose.

I didn't take a picture but I did use a bottoming tap to clean the threads before I backed the screws all the way out. Here is the clutch assembly all apart and off the engine.

Got the flywheel off and I guess this engine was always an external coil engine.

Not had a lot of time to work on this but I wanted to share a few things I have learned so far.

 

First is the Throw Out bearing, I ordered a PK throw out bearing and it came in. It is almost identical to my original bearing that came out of the clutch. The new bearing is about .030" thicker then the old one, I believe this to be caused by wear on the old one were it rides on the pressure plate fingers.

Next item is the Front pressure plate. I have 2 of them of of the tractors and they are different. I has a lot more shoulder towards the engine then the other one does. Also the long one has 3 set screw and the other one doesn't, only 2 set screws.

 

IMG_20140521_151641_044.jpg IMG_20140521_151706_340.jpg

 

Lastly, the clutch output shaft is bent on this clutch so I will have to use the spare shaft out of the other tractor.

The long one was on the WIS. TRA-10-D, the short one was on the replacement Kohler engined tractor. I thought maybe that the short one had been machined to fit. Thanks Daniel.

There is a guy on Ebay that sells PK parts and so far it appears that they are the same parts in both clutches.

They didn't look any shorter, but I didn't really inspect them that closely. I may do a compression test on both to see how they compare.

Got the chance yesterday to do a little more work on this engine and clutch set up. I got the clutch pack all back together with new springs and fingers and back on the crankshaft. Still have to install new bearings on the output shaft and throw out bearing. I used the output shaft to align the clutch pack.

Glad you got some "Hog Time" Brian.  I've not gotten any shop time the last several days.
