I don't know about your nice new skidder but my Dresser dozer with a power shift transmission calls for straight SAE 10 wt oil or HyTran in the transmission. I run HyTran type oil.

BTW is that Rte 15 or Rte 2 out front there ?? Either one I should recognize but I don't ????

Chris oldseabee said the new spec was 10wt oil, but the two speeds have run on ATF forever. i still run ATF, never any trouble, i don't think i'll change. dexron, don't use any new spec atf.

Thanks Treeslayer.
It has atf in it now Iím gonna stick with that.

Itching to get this thing into the woods! Hopefully by the new year Iíll be able to pull a few hitches. Takes awhile to get things done when you only have weekends.

Well got the oil changed, it definitely needed it. Fuel filters are changed, got gear oil changed in the back rearend, couldnít find the fill plug for the front, Iím gonna check in the manual but any suggestions?

Found the leaking seal- itís at the bottom of the transmission where the rear output shaft? Comes out. Gonna check in the manual for the seal number, get that on the way, change that out then Iíll drain the trans fluid and change filter, itíll be ready to go!

Got the arch welded too, I think itíll hold up fine, I donít plan on pushing a lot of trees.
My buddy who just got done logging says Iím real spoiled getting to work on it in a heated shop. Iíll take it while I can!

Both my 666 C9046 series have run straight weight C3 30W oil in the trans since before I owned them. Works well but this is equatorial tropics and that may be heat related and/or give you problems in colder climates.

10W for the hydraulics
DD40 for the Screamin' Demon.

Most Allison and many Clark transmissions of that vintage both had ATF/ red oil as factory spec. All the oil books now show series 3 or better 10W instead. Just as well - I'd hate to have to buy ATF by the 40 gal. drum.

Nice looking skidder I run a 664 daily, great machines. I run atf in the transmission works great also helps to have a different color to figure out where the leak is coming from :)

Rotella t 40w is what I run in my detroit though that's what my local auto store has in 5 gal buckets but it semi like it works good.

Allied saystems had manuals for free if you don't have parts manuals

Well I got the old seal out, and found that the shaft it seals has a slight groove worn in it from an old seal. Probably why it was leaking.

Someone suggested to me a Speedi sleeve. Thoughts?

Iíd like to get something done soon, it canít live in the heated shop for a heck of a lot longer. But now the machine is immobile.

I figured as much. The proper fix is a new shaft. However this machine will not see full time usage, only maybe 2 days a week. Hopefully the sleeve will slow the leak to a reasonable amount. Before it was a pretty bad leak...

no it should take it up quite well for a while, assuming you have regular wear on the old shaft and not elliptical wear. if the old wear is round it'll seal, if its out of round then its problematic from the start.

In truck terms the speedy sleeve will be perfect for about 10,000 miles, but then it starts to wear and you go right back to where you started with it leaking around the sleeve because that groove in the shaft didnt get there by magic.
 Thing is how long does it take you to do that 10k miles? For some thats a couple weeks, for some thats a couple years. But it should buy you time.

Option would be to find a seal with the same outer, smaller inner by not much, and then machine the old shaft down to suit the new seal. Thats a permanant fix until next time too. Much depends on what else wearing is responsible for the shaft wear in the first place.

Fixing old gear to hang together for another 5k hours... sadly I'm too dammed experienced at it

Itís not out of round and the groove is very slight so itíll probably be fine. Another 5000 hours? I doubt Iíll put that on it. I figured tops probably like 20 hours a week (10 hrs Saturday and Sunday) and it wonít be every weekend, itíll take me 6 months or more to put 250 hours on it.
But, I want it ready to go for when I can work and would rather not be wrenching ALL of the time.

if its only slight another option is to build it up with weld and machine it back.

And for quick and dirty a bit of liquid metal or araldite works.

Hmmm....... So, measured the shaft at 2.152", I cannot find a sleeve shaft repair kit that fits that size range. Speed sleeve and sturdi sleeve go from 2.125-2.165, with the closest match being the minimum for the 2.165 sleeve, at 2.162, the 2.125 goes max to 2.130. I know we're talking hundreths of inches, but I'm afraid it's too much either way (spin on the shaft or won't ever fit)
What do you guys think? I need to get this out of the shop...

Wish I could help with the shaft, but I'm no mechanic.  The guy I work for owns 2 Clark skidders, and let me tell you they are as tough as a bag of hammers!  I've worked around the 3 major brand cable skidders (Clark, Deere, timberjack) and the clarks were hands down the best machines.  Even the 664's can handle a hitch of wood that will make you shake.

Perhaps that shaft has already been turned once to remove a previous groove?
Can you get a number off the seal to verify whether or not it's a stock dimension?

Old seal is trashed but the new one is an OEM sized seal. I don't think it's been turned before, but who knows with a 40 year old machine that has unknown hours.

I used Speedi-sleeves on the front & rear diffs as well as the wheel seals on my '75 IH S-8 skidder. They work best when carefully installed after emery polishing any ridges alongside the groove, then after cleaning everything well lay a bead of Loctite 518 on the old shaft to fill the groove and seal any irregularities under the sleeve. Install carefully and wipe away the excess. Let it sit 24hrs before installing the new seal if you have the time, and you'll be good to go for a long time. Be sure to install the new seal with some grease on the lip, and if it's an open seal on one side, pack that with grease. If it's a closed seal on both faces look carefully to see which side faces the liquid (it's stamped).
