2-105 vs. 125 Workhorse Clutch

[Merlin in Rushford]

Hello, Everyone!
I hope you survived our first real blast of winter! We had about 6-8 inches of new snow here in SEMN today, now its just windy and getting colder. All this snow got me to wondering about a good loader tractor.
I really like the White 120 or Workhorse 125, but the 14" single-plate clutch gets to be a workout on the old knee after awhile. The 2-105/2-110 are really nice tractors, but they are getting-on in years now, too. I was wondering about the possibility of installing a 13" dual-plate clutch into a 125 or 145 Workhorse. I know that guys have replaced single-plate clutches with dual-plate clutches in Oliver 2255"s. With the installation of a flat flywheel and a longer Over/Under input shaft, can a dual-plate, 13" clutch be installed? The White 2-180, 4-210, 4-225, 160, 185, 170, and 195 all use this clutch. I know it is more expensive to replace/rebuild, but it is much easier to operate and lasts a long time.
When it comes to clutches, which is more important: spring pressure, or friction surface area? If I were to take a 145 Workhorse clutch and reduce the spring pressure to match the pedal effort of a 2-105, would I significantly shorten the life of the clutch? I know that clutch rebuilders will build custom applications. What are your thoughts?
Enjoy a safe weekend, and a very Blessed Christmas to all of you!

Merry Christmas Merlin, I live on the other side of Albert Lea(West 30 miles) and I know you guys got it worse. Thats a great question, I'll have to ask around. I better get my 880 loader out, wind finally died down.

Have you called Southbend? I know of at least one dealer who, back when BMD was making clutches, contacted them and had them make a reduced force version with the same clamp force. They had no problem doing so, but maintained the same clamp force. So, it can be done.

But to answer your question, total force on the clutch and diameter are what's important. If you had a clutch that was several feet in diameter, you wouldn't need much force. If it was 6" in diameter, you'd need a huge amount of force to have the same holding power.

The reduced pressure 145 clutch is what was used in the 100's. They are great to use in low horsepower conversions. I don't have the exact data in front of me, but I think it has less holding force.

Thank you for the replies!
I was not aware that the White 100 had a reduced-effort clutch assembly. I know there were some other drivetrain changes to reduce weight and cost (i.e. smaller rear axles). Thanks again!
