Help removing pto yoke from bushhog pinion

Try removing the clip-ring. There's a retainer ring in a groove at the outboard end of the shaft. When the shear-pin fails, that's all that holds the pto shaft onto the gear box.

Where exactly is this clip ring? Is there any way I can email you the pictures?

Your yoke is being held on by a bolt or retaining pin. I've seen this done a few different ways. Why don't you put your pics in the dropbox? Here's the link and instructions:

Here they are:

Well, there's obviously no shear pin or retaining ring on that yoke, since it's splined. There almost certainly is a retaining pin through the yoke and shaft. It's probably just a fairly small roll pin, since it takes but a little thrust, and no torque -- maybe 1/4" or smaller.

Look for a hole drilled diametrically down in the neck of the yoke. Drive the pin out with a closely-sized drift.

LLoyd

Yep, looking at pic#2, there's a pin hole. The pin is probably shorter than the o.d. of the yoke neck. Fit a drift in there, and see if it encounters any shoulder in the hole. If so, you've found the pin.

If the pin is out, the assembly is simply frozen. Use a stout ball joint puller to urge it to move. You may need to drive the puller with an impact wrench to get full effect. (the puller should be of the character of those used for truck maintenance, not for a passenger car)

I'm assuming you have the pin out of the hole shown in 1102. There should be nothing else holding this. You're just rusted together. This is just a 540 PTO spline on the shaft and on the yoke. My first trial would be 1) soak it in WD-40 set upright so the solvent can puddle and work its way in. 2) get a puller, you'll need a two sided one, to put pressure on the yoke. 3) pop the end of the puller with a hammer, the shock under tension will normally get it. If you don't have a puller, drill and tap a rod that goes through the yoke end holes, use a bolt to put pressure against the shaft.

If and only if this fails: heat the yoke up seriously with a torch; repeat steps 1 to 3; throw yoke away. This piece only costs $25 at a discount Fleet Farm Supply, its a standard item. Get your new Cross bearing there, also.

I've tried cussing and yelling; but it seldom works

You'll probably get a lot of other good suggestions. I'd wait, read everybodies, then act.

Good Luck, I been there done that all too many times. Karl

There was a bolt and nut through that hole. It has been removed.

Can I go to autozone and rent one of those tools?

You probably can't rent one heavy enough for this type of app.

Just crack the yoke and replace it. Lacking any other method, cold chisel a good, deep groove all the way down a weak side (like, at the peak of a spline on the shaft), then crack it good and often along the groove. Eventually, the yoke will either stretch or crack along the groove, and you can pull it relatively easily.

LLoyd (ps... BEFORE you use that mower, you better make sure you have an over-torque clutch in the driveline, since you obviously don't have a shear pin arrangement. If you hit something really nasty without the clutch or a shear pin, you'll break somethin' inside the tractor, or the mower's gearbox. The clutches are common items available from almost all tractor supplies)
