At the same time, drill into the shaft 1/16 to 1/8 depth to allow for a seating/locking point for the set screws?

If the four set screws would take the torque, all that needs done is cut shaft to length, bore that splined ball seat to fit unsplined shaft, drill & tap four holes, add four set screws. Done. install shaft. OH, don't forget to grease it.
That sounds like way more work than just using Sam's adapter and an existing shaft..... Sam's solution is really a simple one. I'm sure the four set screws wouldn't hold. If nothing else they would back out. Besides, how do you plan on getting to them to tighten them? With the driveshaft installed, there would be no way to get to them.......

J-Meck,
I will just have to put this into the AutoCAD inventor and put it thru the stress test to see if your thought on the set screws failing is true or not. Trying to tighten the set screws, I believe your incorrect in your statement and maybe because you don't see the picture that I was trying to explain. You tighten them down while on the bench.

For those 109 to 169, I still got a better idea. Put new pump adapter on pump, then bolt Cub Cadet CV style drive shaft to adapter, then bolt to factory kohler engine adapter, grease it and your good to go. Don't have to buy drive shaft from Sam Mac and Sam Mac doesn't have to fabricate drive shaft.

I got simple, take drive shaft off one tractor, put drive shaft on 109 to 169 tractor with new pump adapter.

No, I understood. What happens when they work loose? Because they will.
And, I'm not worried that the set screws won't hold...... I don't think the shaft will. It will end up looking like this one. Note: This shaft is wayyyyyy harder than one that you would be using. It's on a 40-45 gal/ min pump.

The driveshaft is not the right length. That's why Sam makes the new one.

Sam Mac,
I do like your ideas and it is cost effective for the parts b/c the drive shafts that I'm referencing are no longer available thru CC but the parts for the shafts can still be purchased new. In comparison to the drive shafts that you are using, they can still be purchased new as well as the plastic barrels. I do commend you in your thinking.

I will consider this shaft when I go to replace the drive shaft and flex connections in my 1872 this winter. I believe the snow plowing is putting to much torque on those flex connections as well.

My 1862 already has the CV joint and have had no problems with it for the 12 years that I have owed it. Reason for me liking the CV joint so much is b/c the 1862 has been fully upgraded and customised with a 48" front end loader, dual brakes, cast iron rear, 600 lb counter weight and more. It's a beast. It also has the Cat-0 3 point hitch with a 2B rototiller with extensions. I can also run the tiller and loader at the same time from the from PTO clutch. It a Deutz clutch with dual pulleys. I got the idea from a guy that wanted me to part out his deutz tractor. His clutch bolted right up to my tractor.

Was the shaft couter bored for the set screws to seat into or was the set screws seated to the smooth shaft?

Hey I'm not trying to piss anyone off here. If I did, I apologise. I'm just trying to point out that there is an alternative. The shaft that I have used and put on my 149 tonight is unaltered and it bolted right up to the new adapter. Works perfectly like my 1862.

Glad to hear that you have a cure. Let's see some pics.

If your talking about my pic, no. The pump was connected DIRECTLY to a motor with a U-joint shaft. (Someone made this set-up) They constantly ran the motor over 2K RPM. The pump shaft was keyed, but the set screw (1/4" set screws) kept backing off, then the key would fall out. I promise, that 5/16" key way will hold more than 4 set screws, but I'm telling you... the set screws will vibrate loose. Proof is in the pics.

Here is what I think. Sams idea is great and I'm going to do a few that way. The cv, 2k and 3k are better then the rag joint system but look how long they lasted. Unless your beating the absolute crap out of the tractor with rag joints they should last several years. The only setup I see that would shorten the rags quickly is using a rear pto tiller and my 982 has the original rags on it yet and it was purchased with the tiller new.
Don't ever buy a driveshaft that is the pre cyclops type. Make one from 5/8 steel.

Sam and to all,

Sorry if I ruffed your feathers but no one believes me that this is a direct bolt up with a new pump adapter plate.

I now have the motor mounted to the frame and temporarily installed the drive shaft. It fit like a glove. Once bolted to the pump adapter plate, I then checked end clearance to the motor adapter and there was about 1/4" clearance to end of shaft. This gives plenty of clearance for forward and rear end play and still having a full set of splines in each CV joint.

The shaft that I used was from an 1862 which is 18 inches long (shaft only). The 4 models that it fits are 1541, 1860, 1861 and 1862. This complete unaltered CV joints and drive shaft bolts directly up with the pump adapter in my drawing. Your pump adapter to these older pumps may be longer or shorter. You'll have to find out if it works with this shaft.

The fan will need to be trimmed to a smaller diameter but that is minor modification

I'm attaching picture of my proof of fit.

Oak,
I use my cub as hard as it will take it. I've actually ripped new flex connections out after a week of usage. Like I mentioned before, I've owned this tractor 35+ years and have used it beyound it's expectations. My usage consists of plowing, discing, harrowing, rototilling, ground ripper like extreme's,, even mowing the grass. This tractor will eventually have an identical 48" front end loader like my 1862 has and will be built stronger with stonger hydraulics. My 149 will soon have powersteering from an 1862. The front axle has already been changed with a frame reinforcement.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
