PTO Over run clutch

So my pto is the original 1-1/8 would it be a better idea to get a over
run clutch to fit 1-1/8 instead of do a pto conversion ?

Unless the pto was leaking, I'd just get the 1-1/8th ORC

But I'm pretty tight.

Yeah I was thinking its cheaper. But didnt know if it was a good idea or not

have been running two of the 1 1/8 ORC for years. 1 3/8 output to fit my mower.

Ok thanks!

Ditto for my shreader I've used for almost 10 years.

Been using one on my 1 1/8 for years.

I've had the conversion ORC on my 8N since I bought it over 30 years ago. I leave it on and grease it regularly and it's always worked great.

I'm going to go against the grain, swap it out. Especially if you want to fully use your machine.

I ran the 1 1/8 for the first +/- 20 years. Had to use the ORC on all other pto implements (since they're all 1 3/8 receivers), whether it needed one or not for safety reasons.

Among the bigger issues:

- Always was an issue on the cone spreader because of the additional length of the ORC meant that the I'd have to tilt the spreader way forward and raise to full running height in order to hook up (because the telescoping shaft to spreader won't close enough), and run it at a forward tilt, even if lifted a good bit higher than the pto. As such couldn't fill up more than 3/4 without spilling lots of seed or fertilizer with every bump. Then, if for some reason would need to quit mid-job, would have to uncouple pto on shut off, otherwise the eventual bleed down would cause the spreader to lower until it was causing the spreader drive shaft to bind (because weight would cause the 1" square tube to bend minutely). Once tried limiter chains, no help. Also cut a drive shaft down once, but then if I raised it too high, it would pull apart. 540 rmp fish flopping 1" square tube = no fun, brittle old plastic sleeve shrapnel everywhere, lots of new fix-its, and need for clean underwear.

- Major issues with the sprayer pto pump. All in regards of clearance of sprayer, in using torque arm to limit pump movement, and weight of pump on ORC (would stress wear ratcheting device into oblivion).

- Would have to remove the ORC if using a dump scoop or back blade, and occasionally with 3 pt draw bar (depending on what I was trying to pull), otherwise it would hit the ORC. Broke a couple that way.

- Major p-i-t-a since means removing zerk, fishing through grease to line up on roll pin, and pounding out and hoping it fits through the zerk hole.

Now I use the 1 /38 shaft, with the spring collared ORC. A much much better setup and very much worth the $75 to swap out. Big time "Why didn't I do this before" moment. PS, FNH parts desk sells them if shipping is pricing you out.

For what it's worth, I did once try the 1 1/8 - 1 3/8 adapter sleeve with a 1 3/8 spring collared ORC. Worked good for about 2 hours of light use, then wear started adding clearance (could feel the slight difference occurring with pto engagement/disengagement). Once that started happening, had the adapter splines turned into metal shavings in about 15 minutes of heavy weeds, and added significant rounding to the tractor pto splines.

I got my 9N in the 1980s, put a ORC on to run the rotary cutter. I grease it every use, more if I'm cutting all day. It still works fine.

Only drawback I see is it sticks out longer than just a shaft.

Adding an external ORC often requires implement PTO shafts to be cut for correct fit up.

Check carefully if they need to be trimmed.

Those adapter sleeves shred after a couple
of hours with a sickle mower.

Whether it is 1-1/8" or 1-3/8", the N's NEED an OR clutch for implements. I replaced my PTO shaft (1-1/8") with the 1-3/8" one due to the previous owner(s) never lubricated anything, and the splines were badly worn, as well as being twisted. Put the appropriate ORC on it, and have not had any issues. Grease it regularly, as well as the u-joints on the drive shaft for the implements. I don't take it off, but have a shield that covers it completely on three sides. I do shut off the tractor when attaching or removing implements; safety first. zuhnc
