Default Hart-Parr 28-50 remove engine?

My dad is working on a 28-50 hart-parr. it's in tough shape but it will go. anyway he's trying to figure out the best way to remove the clutch and flywheel. if anyone else out there has done this he is wondering if it's easier to remove the transmission from the engine or the engine from the transmission. or take both our together???? he was showing me that the engine mout bolts are "leaded" in place. it also appears that the trans input shaft is froze to the pilot bearing in the flywheel. also looks like you have to have the flywheel off to get to the mount bolts on that side. too bad I&T never made a book for this rig....
also does any-one reproduce the eccentrics for the madison-kipp oilers???? out of ten only one is broke... i don't think thats too bad..
thanks...

There is good news Adam! You do not have to remove the engine OR the transmission.
There used to be a reprint book (which I have) that described the procedure but I don't know if it's available any longer.
Anyway.......take off the shifter cover at the pulley end of the transmission. Remove (loosen) the cover from the pulley shaft side.
On the other side there is a cover as well (I THINK) and a sleeve over the transmission shaft which partially runs INTO the transmisson and provides a surface for a felt seal. In that sleeve you will find a groove and there are two holes opposite each other. In one of the holes you SHOULD find the ends of a locking wire tucked in. UNtuck the wire and remove it. In the other hole is a set screw which secures that collar to the shaft. Turn out the screw which will allow the collar to slide on the shaft. Now to the clutch. Take off the clutch collar, unbolt the clutch plate and when everything is free you can knock the entire shaft away from the engine as far as you want. The pilot bearing may or may not come along with the shaft. The flywheel part is self explanatory.
I'm doing this from memory but I'm pretty sure that is all correct information.

Nice tractor Adam. I’ve always loved the heavy cast rears on the early 28-50’s. It definitely gives the tractor a real “tough” look.
