Outbehindthebarn Posted December 21, 2015 Share Posted December 21, 2015 Are all triple countershaft Mack PTO's the same? In other words, if I am wanting to put a wet line on a T2100 equipped Mack, can I use one off a t2090, 12 speed, etc?

b61mack Posted December 21, 2015 Share Posted December 21, 2015 I was wandering the same thing if all Mack triple countershaft were the same, plus if rear mounted PTOs were the same other than ratios. Quote Link to comment Share on other sites More sharing options...
Vladislav Posted December 21, 2015 Share Posted December 21, 2015 Not all Mack triple countershafts were the same.There were two generations of them - T107 and T200.Both were designed with triple countershafts but had different body styles and too probably different insides.Sorry I don't know anything about PTO's they used.

IH Farms 2 Posted December 22, 2015 Share Posted December 22, 2015 I would imagine it'll work the service manual is the same for both transmissions.So there can't be that much different other than the gear ratios Quote Link to comment Share on other sites More sharing options...

Back In Black Pulling Posted December 22, 2015 Share Posted December 22, 2015 One from 2090 should work on 2100 same main body unless your mounting on the back then IDK Quote Link to comment Share on other sites More sharing options...
m16ty Posted December 22, 2015 Share Posted December 22, 2015 I've got a Chelsea PTO for a T2100.The reason I have it is when the T2100 took a dump, I replaced it with a 12 speed 1070 and the PTOs wouldn't interchange. I now have another 12 speed that needs a PTO. I'm going to see if I can just swap the gears to get it to work. If not, the T2100 PTO will be available to sell.

Im not sure about using PTOs from TRTXL 107 series with the T2s and T3s. Quote Link to comment Share on other sites More sharing options...

chilge01 Posted April 29, 2019 Share Posted April 29, 2019 I know this is an old thread, but i'm looking to put a wet kit on my 84 mack mh613 with the t2100 and am looking for some guidance. Local mack shop has no idea what parts to order. I'm trying to set it up to run a three line wet kit for pulling a logging trailer with grapple loader.

What size log loader and pump fit is a must know? You need to figure out your flow/pressure demands to know percentage for Pto. Pump direct mounted to pto? Pto driveshaft otherwise? Etc...

I'm not sure what the specs are for flow rate or pressure but i'll do some digging. As far as direct mount or driveshaft, what would determine that? I don't know much about wet kits.

terry Posted April 30, 2019 Share Posted April 30, 2019 Direct mount bolts right to trans housing, A remote pump has a shaft with u-joints on each end. terry Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted April 30, 2019 Share Posted April 30, 2019 (edited) You would probably end up with a Muncie 828S-M6513-D3A1 PTO in our shop. Go to the Muncie spec assist on the website. You can walk through the set up by answering questions it asks. Really, ethically, the dealer you buy your PTO from is responsible to get you set up. Then you can come back with an oily PTO if you have a problem. You do best at body installers than a Mack dealer. General rule on PTO is go big. You will have a guessing game to figure your torque running through the PTO. We went to 82 series Muncie because when the PTO goes it takes your trans with it. We always used a driveshaft between pump and PTO for log loaders. The pump your going to use is a bit large and will likely never come with a face mount option. On a 2100 the PTO window uses 5th/10th gear. We installed to left front trans window, seemed like chassis favors it on most trucks. If your three line I'd bet a double-gear pump running 2,700 PSI with around 30/30 GPM or 25/25 GPM, 55 gallon res. Like the top mounted Jib-boom cylinder design, save a lot of ding'ed up chrome rods. Heavy to haul, but the reaction link is similar to what Volvo uses in a lot of apps. Edited April 30, 2019 by Mack Technician 1 Quote Link to comment Share on other sites More sharing options...
chilge01 Posted May 2, 2019 Share Posted May 2, 2019 Awesome, appreciate the info! With the three line system, if there is too much pressure at the loader controls it should just route back and dump in the reservoir correct? So if the pump had too much PSI or too high of a GPM it would still work, but pump too much fluid and build excessive heat? Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted May 2, 2019 Share Posted May 2, 2019 (edited) Pumps don't make pressure, they make flow. Resistance to flow makes pressure and heat. That should be an open center valve set-up, so full flow back to res on both circuits when at rest. Too much GPM will build heat if you have plumbing undersized. Too much oil flowing over a relief (because not matched to the engineered flow rate) will create localized heat at the valve. Generally, you will only be running 15-20 minutes at a time so you won't go critical heat......unless….. you plan on playing "forwarder" for another truck(s)? You can lower the RPM of the truck to reduce flow on an oversize pump, but you will end up going under the minimum recommended input speed for the pump. IOW-don't guess on pump. If you didn't get one with the loader purchase.....get the right one. Are the I.D.'s of the pipes on that trailer two PSI pipes @ 1-1/4" and 1 return pipe @ 2"? Looks like someone routed your stabilizer lines outside the receiver tubes? Can't see how those won't get ripped off?

chilge01 Posted May 3, 2019 Share Posted May 3, 2019 Correct, only 15-20 minutes at a time, 30 tops Looks like all three pipes are 1-1/4. I haven't got the trailer yet so i'm going based on some pictures still. I went and checked it out in person once already and took a few of my own photos for reference. The photos below I was going for rough measurements on the couplers, but it gives an idea of the pipe sizes. The third line is currently capped off. Current owner has never used the rig, but previous owner before him must have ran it as a two line. IMG_1101.HEIC IMG_1104.HEIC Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted May 3, 2019 Share Posted May 3, 2019 Mismatched on return pipe size, but probably got away with it. Used as a two line so he could have it as a “grocery getter”, hauling firewood once a year with his lowboy truck maybe? Quote Link to comment Share on other sites More sharing options...
chilge01 Posted May 3, 2019 Share Posted May 3, 2019 Most likely Talked to another local shop and they seconded what you said about a pump sized for 2,700psi and 30GPM. They put together a quote for a PTO with face mounted pump and PTO controls up to the cab, parts only, for $2500. Does that sound reasonable? They recommended a small fabricating shop in town to split my fuel tank for a reservoir and a hydrualic shop for hoses and fittings. Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted May 3, 2019 Share Posted May 3, 2019 (edited) Are they doing a double pump with a face mount? That's a big unit to hang even with a good tail support! Price is too low? They are not going heavy enough spec. Or is it possibly used? Split can be nice in winter if the truck recirculates warm fuel to bulkhead wall and preheats oil. If they put a straight baffle wall in the tank to act as septum they are prone to cracking. If the welder puts a hemisphere section in the tank as septum it will last many years. IOW- cut the end off another tank and install it in the center as the bulkhead divider. Can't explain it, but it holds up... gives flex. If it's a steel tank you can just go thick and straight, aluminum is fussy. Edited May 3, 2019 by Mack Technician 1 Quote Link to comment Share on other sites More sharing options...

I’ve still got the one posted above. It’s available and came off a 2100. Quote Link to comment Share on other sites More sharing options...
