1951 Cub - Problem Discovered Tonight

Did not check to see if the guage showed oil pressure...as I said, I am a rookie.

I did discover that the tractor was difficult to put into gear...lots of grinding...so I stopped trying.

I also discovered that the rear "pto" pulley shaft came loose when I attempted to put the tractor in gear.

See picture.

So I loosened the bolts to see what was up. It appears the shift toggle has come lose from the shaft.

I also noted that the gear oil was low...and past its useful life. Any recommendations what I do.

My plan tommorow is to check oil pressure and do whatever anyone suggests.

Did you remove the cover on the back of the rear end and retrieve the PTO coupler they usually fall onto the gears when shaft is pulled. If you didn't don't run or move tractor to you do.

Are you working without a manual? It looks like you are just ripping things apart - don't end up with seven boxes of parts and no tractor. You won't find anyone willing to put it back together.

Take a deep breath, put down the wrenches, and do some reading. It is rare that these tractors need to be torn apart to work. They will usually work worn out but you can tell that it needs fixing.

Funny.... I thought the same thing last night. Stop and breathe. I have manuals, but I am not referring to them like when I did 8n.... However, I have to say.... I am very methodical about what I take off tractor and how I store it. The pto shaft was a surprise.... I dug in a little to see why it was coming out and it was disconnected already so I really did not take apart anything that was not already taken apart.

That may explain why he is hearing grinding when trying to put it in gear? Previous owner removed pto shaft, dropped the coupler, then could not figure out why it would not work and put the pto shaft back in? Just a thought.

If you are referring to the PTO shifter clutch (or the coupler) the answer is no. That is still held on PTO shaft with the set screw. There does not appear to be anything dropped in the bottom "in the gears" but I am going to look tonight. As another poster suggested....take a deep breathe and slow down without ripping more stuff apart.

Before you start the engine again, prime the oil pump.
Remove the cap from the oil filter housing. At the top, inside the housing will be a hole going into the block. Squirt plenty of oil in that hole. With the ignition off, turn the engine over till oil comes back out the hole. Repeat if necessary. When the oil pumps out the hole, the pump is primed and you can put it back together and run it. It may take a few seconds after the engine starts for the pressure to register.

Will prime it. Thank you
