Cub Cadet 1450 (17 hp Kohler) with a Broken Drive shaft – would appreciate any advice
Greetings and thanks for letting me join your excellent forum. I am hoping you might be able to help me with a broken driveline problem.
I recently purchased a cub cadet 1450. It came with a tiller, snow thrower and deck mower. I am pretty thrilled about using it– it is my first tractor. Unfortunately, when I started to mow the lawn, the drive shaft broke where it is coupled to the hydrostatic. It broke right at the roll pin inside the first coupler (attached to the hydrostatic). This caused the flexible disk to rip apart, and the drive shaft - with the second coupler and disk still attached - banged about and chipped up the coupler still attached to the hydrostatic. This action also dented up the fluid filter but there are no leaks. Needless to say, I thought I ran over a huge object with all the banging and shaking that occurred! But I did not hit anything as far as I can tell. Not sure why it happened. My mover belt also frayed and some threads wrapped around the PTO – I think that is OK.
When I looked underneath, I could see the problem and set to taking things apart. It appears that the drive shaft is custom made. I also noticed that the driveline does not resemble the factory drivelines pictured in this forum, nor a driveline diagram that a Case IH dealer faxed me. My driveline consists of a universal joint coming off the engine – then the drive shaft – then the coupler/flexible disk/coupler – then the hydrostatic. The parts diagram shows a front coupler /flexible disk/coupler -then drive shaft - fan – coupler disk combo – then hydrostatic. I suspect my combination might be different because the 17 hp Kohler series II is not original? and maybe the distance between the engine and hydrostatic required a custom job? Anyway, I think I am now stuck with two choices: do I order original parts and see if they fit? or do I get a new drive shaft made, and just order a new rear coupler and flexible disk? Also, is the small fan that fits on the driveshaft necessary to cool the transmission? Mine had no fan. Could I replace the factory rear coupler-disk combo with another universal joint if I make a new drive shaft? How would I measure the length for a new custom drive shaft?
Any advice would be much appreciated. I have ordered an owner’s and maintenance manuals, but don’t expect them to arrive very soon. I am semi-mechanical if I have help
If I can get a digital camera, I’ll post some pictures. Thanks for reading this longwinded tale!
p.s. One other problem while I am at it – I noticed a narrow rod -approx 8 inches long - hanging down from the “brake shaft” (the shaft that passes through the tractor from left to right, and rotates when you step on the brake, and has the metal piece that pushes a button switch in front of it) . Where should this rod go? Is it part of the brake system? It looks like it might have been attached to a spot near the right side of the hydro - looking forward. I will be better informed when my manuals arrive.
Sincerely,
Mark Kornder – temporarily stuck pushing a lawnmower near Pike Lake, Saskatchewan but really exited about owning a cub cadet!
