update on '53 cub

Postby k hutchins » Sat Oct 15, 2016 4:00 pm

Ok good news/bad news

I got my friends cub running.
New battery, oil and filter (yes I remembered to prime the pump), fresh gas (had to make a new cork gasket for the sediment bowl), cleaned the cable connection to the starter, then tried it and away she went.
No runs, no drips, no errors.

Now on to the next phase.

The PTO won't engage, the gear seems to move freely back and forth on the rod, but I can't get it to engage the drive gear. I held the shifter in place and tried to just bearly let out the clutch figuring it was just off a bit and would click in, but no such luck, I could just hear it grinding.
Does anyone have advice for a quick fix. I would rather not pull it if I don't have to, but if that's the only way so be it.

Thanks in advance, I know you guys won't let me down.

The pin on the shift lever may be worn flat and the clutch isn't moving enough to catch the splines on the input shaft. If the splines on the shaft are worn rounded, the clutch may not be able to engage the "good" splines. You might try loosening the plate that holds the shift lever to see if you can move the lever back far enough to engage. Not a fix, but then you'll know that you need to pull it off for repair.

Edit: if you remove the fill plug, you can look inside with a light and possible pin point the problem.

Thanks Bob
I did pull the fill plug, and all seems in order.
As to the shift lever plate, that's another issue, it's not there, so no travel problems.
I held it back with pressure on it then let the clutch out slowly, the gears just ground without engaging.
It could be the teeth on the PTO gear are worn down, I'll have to check again.
Is the whole mechanism visible if I pull the trans cover plate? So I can really see what's going on.

No, you either need to remove the triangular plate that the shaft exits through (which doesn't require draining), or take off the whole cover (which does, but makes it much easier to work on it). The PTO bushing may also need to be replaced.

Hi,
You could try turning the end of the PTO shaft by hand, with the engine off, and pull back on the PTO lever, and see if the PTO will go into gear.
I'm not sure which cover you meant, here is a pic below of what is under the shifter, just trans gears, the PTO parts are not in there.
Looking in the oil fill hole, or removing the PTO is where to see the PTO shifter parts, like Bob said. :)
