Garrett 15 Skidder will not go into forward or reverse, any suggestions out there?

mike_belben

Gearbox or powershift?  


It happened slowly, suddenly or the machine has been sitting since the trees around it were a twinkle in a birds rump?

On this critter the forward reverse stick is just forward of the gear shift (which operates like it should) there appears to be a rod running into the gear box from the forward reverse stick.  Been sitting 5 years and got her running fine, had trouble pulling out of reverse to go to forward..now won't go into either F or R.😬

Sitting with oil on one side and air on the other means the gearbox is probably half rust, including any syncronizer or sliding clutch parts and the splined shaft that the sliding clutch in the reverser device runs on. If not that style then a fork may kick an idler gear on a sliding shaft and the rust on the shaft is binding the gear and/or fork lever.   

If it has a topload cover, remove and see what you can see.  With any luck it can be deboogered while still in the chassis by some elbow grease and diesel fuel flush.

Thanx Mike..This is an old machine (mini skidder) and I hoped somebody else might have experienced this issue and figured out a shortcut, you are right...probably need to open her up and see what's stuck.  The problem is probably high enough in the gearbox that the oil level won't lubricate unless the gears, etc. Are throwing some oil...sitting around 5 years doing nothing and I'd probably have some things bind up on me too!😬

I dont know the skidder but i went through the same on a 30 year parked roadranger.  


Even rolling over 180 with a wrench or starter bump every 6 months will do wonders for old junk.  The thinner the oil the faster it evaporates off. When grease squeezes out of a joint, i wipe it on all the threads i can find. Talk about a joy when its time to do a leaf spring or tie rod end.

my garrett 15 has two shift levers, it has a 4 speed manual and another lever on the left that shifts the hi low transfer case . If its not in high or low it will act like it is out of neutral , also check the clutch adjustment if the clutch does not release it wont shift correctly and my not [I have typed a profane word that is automatically changed by the forum censored words program I should know better] at all

Gary Davis

please post pics its always nice to see another garrett 15

looks like spell check wasn't working it was supposed to say ( it won't work at all)

Thank you guys, I don't know how to post pictures but I will try.  Will also try to remember the whole tale involving this machine and get that on here for you to read, I found it on a used equipment lot outside Bellingham WA...and after a horrible tale of government restrictions, it has found it's way here to Missouri.  The forward and reverse on this is right in front of the 4 geared shifter which works fine.  Thanx again for the help!

Gov restrictions to move from state to state? I would never think to ask.

I am in my fwd/rev box on a TJ now. Not much in there, if the problem is in there open to top and see.

 Any chance those levers go into a Cotta transfer box? I have a pict of that.

the garrett 15 has a 4 speed transmission with reverse the other lever is to the high low transfer case
my book calls a warner t98a or warner L2  with a 172 cu in gas rated max hp of 68 or a 172 cu desel rated at max hp of 59    I have not been able to find about  the torque

Hey guys..kind of figured out the image deal, there she is!  If you notice that weird contraption with the winch on the blade..that's part of the story of what we were doing with this up in Washington and BC years ago.   That shift lever with the tape on it is the forward and reverse, it is just forward of the 4 speed shifter..center of the machine.

Mike..I have been doing Musical Instrument Wood for almost 4 decades.  I used to roam around the Pacific Northwest buying Old Growth Sitka when I noticed these giant Big Leaf Maple trees that moved in after the mature softwood was hauled away years past. We began selecting standing maple for curl, buying it from the landowner, falling it and cutting the stems into 4-6 foot lengths, then into quarters.  I would cut the centers/heartwood off, load them onto my truck and trailer, head up into the Rockies where I could get them frozen solid...then home to Missouri where we'd process/mill them into musical instrument material. We have some special processes to preserve the very white natural color so we had to get them back here quick and mill them up and dry them before they changed color.  After about a decade of doing this a dual citizen friend allowed as how this was looking profitable, he would begin doing all the legwork/hunting, do some falling and call me when he had a load organized.  We needed a machine to move trees in a very selective cut scenario and we needed some thing to load the cants (400-800 lbs. from 3-5th diameter trees) onto the truck and trailer.  Thus the little skidder, and the tripod with the winch allowed us to lift the cants onto a flatbed. Along about 12 years ago the Washington State Government decided that a permit was required to cut a tree, even worse they informed me that driving down the road with a load of cants made me subject to inspection and without the permit...I was in trouble.  Since the application for the permit required pre inspection of the site, a delay for the paper and then a post inspection of the site, our requirements to preserve the wood didn't work with the government demands for a permit.  I was often buying just one tree, even out of peoples yards or small acreage and we had to move fast to get the wood going before it spoiled.  They would make no exception for us and so, there goes a good small business idea and a good job for my friend.  Since it wasn't needed in Washington, the little skidder found it's way back here to Missouri where it is in a semi-retired mode so to speak.

Nice looking machine. Have you fixed the shifter? Or problem? Is there a cover under the dash panel that comes off? Seems that would be a good place to have a look.

Thank You Sponsors!
