CC 100 Stuck in gear?

Hello All,

Last snow storm I was blowing snow with my brand new cab I've been building for the past month.Tractor was working great I was working the 2+ feet snow banks slow and steady when I couldn't shift into or out of my gears finally got it to got it to go into 3rd and brought it directly into the shop. Long story short the throw out bearing on the drive shaft imploded all over the drive shaft. Removed the cab, snow blower, motor dropped the shaft and replaced bearing, teaser spring and clutch disk. Thankfully for this board I had plenty of references to go by that gave me the confidence to tackle this project. My question now before I put the motor back in should I be able to shift in to all the gears. I can go from 1st to reverse but can't get it to shift to 2nd or 3rd. Or for that matter am I still in 3rd from when I pulled into the shop? Did something get caught up the the transmission? Is it really shifting into reverse & 2nd How could I tell with out putting all back together just to take it apart again? Thank you all so much, I'll post a picture of the cab in a little later because I know how many are interested in those home built units

Well goes from neutral to first and 3rd. Still locked out of 2nd & 3rd

You should be able to shift it without the engine in place. Jack up one rear wheel, put it in gear and by rolling the rear wheel that is off the ground you should be turning the drive shaft. Try all 3 forward gears and reverse. I reverse the drive shaft should turn in the opposite direction. If not you will need to remove the shifter and see what is going on inside the transmission.

Thanks Sam Mac,

Here is what happened. All descriptions are as if I was sitting on the tractor with the right rear wheel off the ground.
Neutral: Drive shaft spun with the wheel.
Stick in reverse position: spun lifted right wheel forward (clockwise) left wheel spun in opposite, drive shaft did not spin.
Stick in the 1st gear position: spun lifted right wheel forward (clockwise) left wheel spun in opposite, drive shaft did not spin.(same as reverse)
I had the same effect with the creeper in hi or low.
Shifter will still not go into 2nd. or 3rd.
So what does this tell me? Is there a way to get to where I want to be with out splitting tractor. Finally where and what am I exactly looking for?

Thank you all so much

I think you have something wrong with the shifter forks inside the tranny. You are going to have to split the tractor, probably (although I worked on my 100's tranny without doing so 'cause I couldn't get the pin out of the coupler. There will be just enough room to get the tranny cover off and look inside.) Then you can move the shifter around, check the shifter rods and see if the bolts are tight on the shifter forks. I suspect that a fork bolt loosened up and that is keeping you from getting into the other gears.

Thanks Fixer. Is the cover you're talking about on the top side or the front transmission?

Take the shifter cover off and see what your forks look like. I just hope one's not broke but it does happen.

Yes, the "cover" is the plate that the shifter goes through.

From what you have said I feel pretty sure something has come loose inside the trans. But before you take it too far apart, try doing the things you have already done but do them with one of the rear tires firmly on the ground.

When turning a rear tire with the rear end in the air, the movement (like anything else) will take the path of least resistance, and almost always simply turn the other rear tire in the opposite direction.

In this case you are wanting to make the gears in the transmission rotate, keeping one tire on the ground will direct the "force" back through the transmission.

Thanks Sam,
Just finished disconnected the rear drive pin. So if I'm to understand you correctly theoretically if I keep that other wheel from spinning I should be able to spin the wheel I'm trying to spin with out the other moving wheel?

Since you havae got the pin disconnected and the drive shaft is loose in the coupler, go ahead and split the tractor. It is easy from this point on. Just remove the 3 bolts on each side that holds the tranny to the frame, jack up the frame in front of the tranny and roll the axle out. Then you can remove the top cover and see what is loose in the tranny. Don't worry about which tires spin when yet. Just look inside the tranny and see if the shifter forks are working.
