i have that set up in a valmet forwarder its been bomb proof. the only part i have replaced is the turbo drain line. that motor shakes so bad at idle it cracked it
snowstorm have you tried setting your idle up had to do that in my 610 timberjack with the 4bt fixed a lot of vibrations crane was so fast et the idle at 1200 and ran the crane on idle
David, Congratulations on the skidder. Old Seabee is the Man when its comes to Clark. He has helped me out and several other people also . I have a loader with a Clark 3 speed in it . Not sure if the same transmission or not . I think the general consensus is they are a good transmission. Mine is a 28000.
Does it have the Deere winch?
119 gearematic, hyd operated.
awesome machine. Best transmission ever IMO. Probably the most desirable cable machine ever made.
David, I am going to assume it has the same transmission as mine. If so there is a hose that goes from a master cylinder to the spool valve that places the transmission in neutral. Mine is actually part of the breaking but could also be a separate petal.
Ohio Bill, sounds like that separate pedal or the same function as the mystery pedal. I will take a pic When it arrives at the end of the week. it comes with a manual and I will investigate it. the machine saw a fluid and filter service in Dec 15 and its' been working abit. Sitting is the worst thing for all machines IMO.
Declutch
Does the DE clutch work off of a solenoid. Thats the only thing the owner said is not working.
The declutch is hydraulic from brake master cyl. The pressure line will enter the transmission control valve in between the two shift spools. Often a mico brake valve is used to turn the declutch on and off. And never put brake fluid in the master Cly., only use the same oil that the transmission uses.
Took delivery today to my jobsite. Checked all the fluids and drove it in the woods abit and runs very well. real straight for a 1995 240B model. Cummins and a Geramatic 119 dash controlled with the 3 speed clark powershift is real nice. Can't beleive how straight and maintained and tight. Every pin has been done including cradle. What does this clark powershift like for fluid and where is the filter and drain? Looks like red type F tranny to me in it topped off. Is that ok or shoulld there be something else in it.
ATF. The filter on the 380 is in the engine compartment on the driver side. It's a big spin on. The filler neck is on the same side near the rear of the transmission. Idk where they would have routed it on a 240. It's under the left floor board on the 380.
Nice looking Skidder. I suppose that brace up by the rollers r is for pushing trees when hand cutting a leaning one? Haven't seen that before, other then one or two others on this forum. Looks like a good idea. A lot higher then just the blade.
Nice Skidder !! i believe Dextron ll is the correct trans.oil.
Clark did change transmission oil specs mostly pushed by mine and quarry owners with large loaders and dozers. It was found that they got better life under the new specs.Clark trans oil specs., from 30 degrees and up 30W engine oil, from -10 degrees and up 10W engine oil, API- CD, SE, or SF, from -30 degrees and up ATF. Unless you are in a real cold place, ATF isn't needed.
Looks like a good buy. 8) 8)
Question Old Seabee, It has dextron now but for summer use if I change it to 30wt oil will that mess anything up seeing how its been run on tranny fluid? She pulls real good. 1380bd/ft out of the hole no problem. Power shift is nice.
Looks like you got a keeper.
SweetI am envious a very nice machine.work safe, all the bestAl
So far so good, will take some time to get used to it and maintenance points but that will come in time. Headed to the job to take some hooks and sliders off as they were doing cordwood and running 12. Gonna take 6 off, lugging that around yesterday just about killed me. Just in a short time skiddin yesterday it's alot bigger then the 225 but actually turns better in the woods because of the newer no spin in the rear. dosen't crab walk at all. I am grateful to be in the woods with such a nice machine. Thanks all.
Your choice, changing oil should not hurt anything, may be a little sluggish on cold mornings. You are in Mass. so dexron should do fine for you, lot of skidders out there running dexron even down south where I am. Where you get an operator that is to lazy or stubborn to down shift, push the machine to climb a steep grade in 2nd gear instead of down shifting to 1st very little time is gained but the oil temp climbs up to dangerous levels and thins out too much to do it's job of lubing, result is shorter trans/converter life, that's when the 30W will help. Like I said the spec change was more for the big machines in high cycle jobs I'm not a big fan of mixing different types of for no good reason. All that typing is just me talking, point is that unless you are having oil heating problems stick with what you have but keep the level topped off and change oil and filter on schedule and keep the engine cooling system in good shape, not sure about the TJ Clark machines had the trans oil cooler in the bottom tank of the rad.
Nice looking machine David! Should make a nice machine does that have the same 18000 Clark Trans the 240A power shift had? I know I guy who bought a 92 240A power shift in 93 he ran it for years and pulled a lot of wood and big hitches with no problem!
Nice machine! I am jealous. I have an oldie. I run the Napa TO-4 10w oil in my clark trans.How much does she weigh?
Gonna stick with the tranny fluid, bought a pail of it today for the future plus a few filters. The machine must weigh around 20k. ran it all day and getting use to the controls which are different that the 225 for sure. Pulls real good with that winch. The 1995 240B has Donkeys on the winch side covers. Was that something Gearmatic did for Timberjack? The 23.1x26 are really stable in the woods. So far so good.
that is a very nice skidder , it will pull you a lot of wood
Congratulations! 8) that skidder is sweet! I sat in a brand new one at the NE logging show and thought" some day". Glad that day came for you. That is a REALLY nice skidder! Work safe!
What a cable skidder! Congratulations. That's a beats of a line TJ. I always liked your old 225 though, that was very sweet too. But this girl is in another category. Good luck.
Haven't got my manuals yet for the machine or winch. the winch I believe is a 119 Gearmatic and has the Donkeys on the side covers. it seems to free spool kinda hard and what would be the first thing to do. Should I pull the side cover and investigate the Brake band clearance. Also will keep winching in a bit once and a while and I just throw the tranny in N being a powershift and that stops power to the winch. is that dirty clutch disc issues. The fun begins and I love it.
In neutral the pto shaft is still spinning right? It should be.(there not donkeys it's a timberjack. a timberjack was a mythological creature that kept loggers safe) it's still a 119 gearmatic right not a Deere winch. I've never had it keep winching. It sounds like the clutch bands are to tight maybe. There is the brake band freespool adjustment on top of the housing it's an Allen screw. It's on the hydraulic cylinder side. Right behind the raised housings for bolting a fair lead to.
On the 380 with a 32000 Clark and a 119 gearmatic the winch pto only stops in gear at a stop. In neutral it spins. While moving in gear it spins.
To engage the winch I put the transfer in N and the shifter in 1 on the power shift lever and that engages power to the winch. Yes the Timberjacks are on the side covers. I will look for the allen adjustment screw on the hyd side in the back. turning out would give the band more clearance. It's definitely a 119 Gearmatic.
It also has power of course moving fwd in gear.
My winch is a gearmatic 19, mine winched in by it self when the clutch bands were adjusted to tight, I made them a little looser but still had a a high spot so it pulled the cable in a little bit every rotation of the drum, backing them off some more did the trick. I bet your clutch bands are too tight, sometimes with a change of the weather the bands swell on mine and it winches in by itself or tugs back a little, then I freespool with the engine off. Next day it will work fine.. Gearmatics are fickle.I have a 2 speed clark transmission, my pto shaft is always spinning to the winch neutral or not maybe 3 speeds are different but the winch should have power in every gear including neutral.Great skidder by the way, must be a dream to pull logs with!
Took me too long to write that nevermind about the transmission part our transmissions work differently I guess.
If my power shift fwd and rev lever is in N there is no power to the winch. Hope to get the manuals wed this week.
The only time the pto shaft should be stopped is if your stopped in gear (fwd or rev) In neutral the pto should be spinning. Pto comes directly from the Clark trans. There isn't a transfer case right? If it stopped in neutral the clutch band must be to tight. That would be my guess.

That would be my guess.a thought.....if his clutches are tight or came apart, could that stop the shaft in N at idle? in effect stall the converter at idle. that is what happens stopped in gear at idle.also David, under stand you will have no winch power at idle, all power goes through the converter so you will have to over come stall rpm to make the winch wind in a load.
I think we are talking about a different beast here on the 240 power shift. The Clark powers up the transfer case in front of the winch , it is not direct power from the tranny to the winch as mentioned here. The transfer looks identical to the one in my 225A and 230A. I will pull the cover of the transfer today and get a pic.
Yes the transfer case is not used on a 380 or the Clark right treeslayer? The Clark is a stand alone unit.

the drivetrain on the 200 series has been the same since the 60's. the winch (T30, timberjack model) is just a gearmatic with an external slave cylinder for the brake band. I've the same year machine but with a manual gear box. Too bad you still have to put the transfer in N to winch with the PS transmission A live pto like the 300 400 series machines would be really nice on a 240.
It must have to do with room. The fact that a 200 series is offset. The transmission in them is on the right side of the machine.
To be honest with you. I'd like to see how they fit a Clark in it at all. The fuel tank was always right there where the Clark would go. I wonder if they put it in sideways or what. The only powershift 200 series I've ever seen had AT 545 Allison truck transmission in them.
the seat is what is offset, the drive line is in the center of the machine. it is the truck/school bus transmission (at545?)i thought the power shift 240s where 6bta motors not 4b's I have a 6bt motor siting on the floor to put in mine this summer.
Yes the truck school bus transmission AT545 . With a manual valve body. The ones I've worked on,one had a 353 Detroit it's a 230.and the other has a 453 Detroit240.Isthe engine transmission dead center? I'm trying to picture it but I thought there somewhat offset to balance all the weight of the left side cab and seat. I really never studied the line up. The Clark is still a big unit to fit in that space.
Pretty sure it's a 2800 tranny and is centered in it. don't even want to talk about pulling it as I might jinx myself. It looks like a tight fit. I will take pics tomorrow of how the tranny sits in the 240. was busy getting a load out today before its 60 and raining wednesday. Crazy weather for feb. Lovin this machine.
I donot think there is much difference between your 240 and my 230, mine is a 97 with cummins and big rearends , gearmatic winch . One thing thou , when I bought mine they just put a brandnew tranny in it and I figured a 4 speed but nope its a 5 speed with reverse in it , your tires are better than mine so that will weigh more , Mine with no chains on it is right at 18,000 pounds as I have put it on the scales more than a few times
There was another Clark trans. used in the early 664/666 skidders that was a 2 speed with a work and travel range so it was really a 4 speed fwd and 2 reverse (2420 trans.), not sure if TJ ever used it. it was only about a foot thick and maybe 18" wide the range shift was a sliding gear in the bottom shifted by linkage from the lever in the cab. a lot of them had the work/travel range lever removed because the machine would do 30+ MPH in travel range and was hard to control with the stick jerk steering.
I was told the 240 power shift had the same Trans as a 664D but I've only seen the one in person and didn't really take a close look at the trans
I will take some pics tomorrow, no work for a few days as it's raining like crazy here and the landing is soup like everyone elses. I get my hands on the manuals tomorrow also and that will tell.
The 664D had the 18000 Clark transmission which was a smaller version of the 28000. It also had the converter and trans. all together in one case. There were several versions, a short drop version, and trans with separate converter, the version used in the 35/45/55C loaders was without the mounted brake or the PTO shaft but did have the trans/converter in one case.
Question for Clark 2800 tranny in a 240b Timberjack. just started doing this so don't know if its' normal or something is up. When I go from fwd to rev or rev to fwd the charge pump gauge drops to 100psi and the minute I throttle back up it goes immediately to the blue zone on the gauge which is where it should be. don't think it was doing this when I first got the machine three weeks ago. Fluid is topped off and its operating and shifting smooth. Just wondering.
My gauge on my 28000 is on the clutch pressure. When I shift, BAM, its in. No real pressure drop.
Clark 28000 trans could be modulated for forward/reverse shifting without stopping. The modulating valve was about 1" thick sandwiched between the control valve and the trans case. The clutch pressure would drop off during a directional shift and build back up in the clutch for the new direction, this would allow the clutch to slip during engagement to prevent shock loads during the shift. We didn't use it in the skidders except in the 18000 trans in the 664/665D skidder and some wheel loaders. Don't know if TJ used it or not.
Thanks Spartan, and Old Seabee, no issues with shifting, nice and smooth and makes sense that a modulater would be there for the fwd, rev changes in direction. don't think the gauge was moving like that before but can't be 100% it wasn't.I kinda have to go for it as mud season is upon us and I'm at the end of a job. as long as the temp is good and the psi is up during motion it is gonna have to be what it is. Maybe I will change the filter out, it has about 400hrs on it and I think 500 is the service interval.
Old Seabee, yes it has a mod valve, guess the drop on the gauge might mean its' working. as you said, sandwiched between the control valve.
