Re: Parts 154 "resurrection '--- has cracked head

Knowing how.my.projects tend to "snowball" I mist ask this question....
I've read many posts re: upping the power output of the C60. Changing carb, shaving head, port matching manifolds, etc...... While I agree that "if u need more power u probably need more tractor"; I also think that having a little more umph wouldn't hurt.....
My question is this::: Does the torque increase exponentially with the HP???? Chasing a few HP for a negligible boost in the torque is a no-go for me.....
Just curious .....I've never seen the torque boost questioned or answered (unless I missed it somehow!!).
Thx!!
John

The torque only changes due to mass and a change in RPM. Since the mass is likely to stay the same (negligible differences in piston weight), the only change to torque is an increase in RPM.

Just an update..... I've decided to leave head alone for now (there is a method to the madness!!) and continue my trek rearward on the machine.
Got all new clutch, t/out brg, flywheel (broken), clutch brake assy (broken). Something felt weird Ion input shaft of Trans. So popped top of Trans and found it to b dry, as well as a broken 2-3;shift fork. Got foreman at work to weld fork for me. Gears don't look gr8, but jo.missing teeth, excess side/end play.
Going to try and g]et her built back up this weekend. For furthering ⁸uuuuuu assessment and b also to get it up into the shop,

Down a bit in my link is a chart on the C60's HP to torque.

There are several dynameter tests on this site that confirm the information posted by Jim Becker in my link.
I have an excuse. CRS.

Figured I'd contain this disaster in 1 thread... Had to take an extended break from Cub to handle other matters. It appears I need my vision checked, 2-3 slider is missing a tooth, and another gear (forget name) has 2 or 3 in a row round off. Like I said unit was dry.... So I'm gonna have to rebuild trans conplete..... Good thing I literally have no money in purchasing this thing!!! I figure by the time I'm done I'll have enough in it that I could have bought a pretty "nice" one. Although this way at least I know what I have. Going the other way I may have merely purchased a pig with lip stick!!! Anybody in the upstate SC area have a good Trans for a 154 for sale???? Probably my best out.... Of.course hydraulic pump.probably bad from being run dry. Oil level was not overfill when I got it. Don't see abnormal leaking from rear seal, so im.guessing the fluid went into the finals, as there's signs of leaking on both. This thing sat in a shed for years so who knows..........I guess I'm gonna have to wrestle it up into the shop to split it..... I'll update thread when I have further "good news" :shock:

You can do what several folks here have done, get you hands on a Cub Cadet transmission. You can use the entire gear set in your present case or with a few minor changes, swap in the complete trans. They seldom see the hard use that a Cub can sometimes be subjected to. On one of my tractors, I used the complete trans, I picked it up at a swap meet for $75. It was in beautiful condition inside.

Probably dumb ?..... is it possible to swap trans gears without splitting unit??? I would prefer not to split where it is currently resting. Would rathernswap.em in then limp it up into the shop........ Split it, go through trans and finals at that point.......

I’m afraid not, it’s bench work. You’re going to have to limp it to the shop in it’s present condition.

Thanks Gary!!! That's what I was afraid of!! Oh well, it'll b a major pain. But once it's done, it's done... Onward and forward!!! The tranny is trashed really to the point of replacement. But if the finals are OK and merely require a reseal and brake replacement. Then I'm good with that!!!
When I'm through with her I'll know her inside and out and exactly what I have!! Thanks sir!!!!

Would have the rear half of this 154 I junked here. Motor goes in 1 of the 185's IF__IF__IF I live long enough! BUT I am in IL. so no help there!
Everything was good. Found bolts broke off in the rear frame after I got almost done with it.
There were some heads NEW for $100. on epay last year.
