1947 2N fired up!

tracman · Jun 27, 2011

Thanks to this site and serval months of going over a few things such as the 12v alternator, ignition system and oil system the '47 fired up right away. Lots of smoke at first but cleared up. I think the smoke was mostly form the oil soaking in the cylinders while I was fixing a few other things. Now I have to put a new bearing and seal on the PTO shaft. My question is : how dificult is it to remove the the sleeve to change the bearing? Are the instructions in the repair manual sufficient?

my 49 8N had a bad leak on the PTO shaft and for $100 I literally did a 20 minute swap from old to new. hint, have your back wheels up on something and you'll probably not even loose any oil.

the pto repair is not a hard job. you can change the bearing and seal, wear ring and gasket for about half of the entire assembly, depending on where you buy the assembly and the parts.. etc. all the aprts are available at a cnh dealer.. if you do it as an assembly.. get it online from here.. slide in, slide out. rear wheels up on a ramp or nose down.. clean the gasket area good.. etc.

if the bearing is not loose allowing play.. i generally don't change them

i did a good writeup of pto service in the n news a while back if you get that magazine.

grease the seal before sliding the bearing carrier and seal back on the shaft and ring. i used a 2 5/8 socket to drive the seal.. though a fancy seal driver will likely do..

i used angle iron on the seal ring

pipe would do.. etc..

have a board and snap ring pliers and lil screwdriver to pry the rings out.. tap the pto shaft external part down on a board and the bearing carrier and seal will fall off the shaft and bearing assy. pretty much reverse to reseat them..

give yourself about a half an hour to rebuild it.. or 10 minutes for the swaped assy.

" hint, have your back wheels up on something and you'll probably not even loose any oil. "

Sometimes saving 5 minutes can cost you 5 hours.

If you have a worn front seal, jacking up the rear end of the tractor will fill up the bell housing w/ hydraulic fluid real quick. And, if you're really unlucky, you won't notice it dripping out until the clutch disc is soaked in oil.

It doesn't take 5 minutes to drain the hydraulic fluid in a clean bucket & replace it when you're done.
