Thanks guys, this truck is on 22.5 rubber and 4.17 ratios. It was built with a straight five speed and obviously a road tractor.the deceased former owner had this 10 speed installed as the five speed was just to wide spread in the pattern. I think it can be used with these rears if careful on things? Rob

Thanks Chris, is the 2090 the same length as a 2100? Rob

Happy B'day guys. I gave Jaime the day off to celebrate with his family so I be "batching" it tonight in the shop. Rob

That last statement is why they can get so much done. I'm pretty good friends with the builders of sawmill equipment here. We are always swapping work needed done. Don't think I ever delivered anything myself down your way but used to send quite a bit out when moving cars between locations. Still running a VH4D Wisconsin engine eh? Those are getting damned expensive to rebuild anymore. I had one in a L775 New Holland skid steer loader and it was a good engine but costly to maintain as much older equipment gets...... Rob

Hi David and thanks. I was thinking by the way this this pulls from a stop it was in the high eights for reduction. Everything else I have is in the 11.5 or lower so don't think I'll rebuild this one for working in fields. I can't argue for free as this is the truck that was left to me in the estate. It has always been more difficult to shift than the others but this past week hauling my trailer it became unbearable to live with. I want to use the truck for some hauling and a customer is willing to let me use their dump trailer at will around the shop. Last night when I got the top cover popped loose, I propped it up with tapered builders shims and blocks of wood to keep it elevated. With sliding the center clutch forward exposing the splines on the mainshaft, there is about 1/8" twist to the splines; a dead giveaway there are problems internally. I have the two stick six speed in "Project R-12" that is the TRXL-1071 and has the 23:1 reduction. I may use it as it won't do so well behind the Detroit engine. I'll do some length measuring tonight for that idea. Otherwise I'll need another trans, driveline, etc. Would you know if the nine speed is the same length as the 10 speed currently installed? If so that may be the way to go. What series of nine speed would you recommend? Rob

Damn you had to bring that shit up. Thought I'd done relegated that portion of life to cold storage...... Back from the days of old when I was a connoisseur of cheap wine.Any nasty looking green color sawmill equipment at that mill? My trucks hauled a lot of debarkers, end mills, slab saws, and parts of a scrag down that way. Good friends of mine in the little hamlet of Inbreadedness, (Farmington) build that stuff. Rob

What are the low, and reverse gear ratios in this T2100 transmission? What would be the best unit to replace it with to haul dump trailer for seed and rock into and out of dirt fields? Don't know if I want to rebuild this one or not as it has too fast of reverse for my liking. Thanks, Rob

I agree. My 74 RL797 is on Reyco but with 4.11's and that would be marginal I'd think. Rob

Tonight I was able to remove the bolts securing the top cover and hold it up high enough to get the shift forks to clear the sliding clutches. With the trans remaining in the truck there is not enough clearance to remove the top cover. Using a long screwdriver to push and pull the sliding clutch gears takes a considerable amount of force to make them move. Using a bright flashlight it is clear to see distortion to the splines the sliding clutches ride and bear upon. I'll price a rebuild kit for this but may also look to swap to a nine speed instead. This one has a bit too fast of reverse and low speed. Rob

Takes a hell of a tongue to do that. maybe that's why "Momma" stays around? Rob

http://cgi.ebay.com/ebaymotors/1985-MACK-Dump-Transfer-Construction-Truck-/220945386034?pt=Commercial_Trucks&hash=item33715f0a32 I think I'm done collecting trucks till something gets done around here but this looks pretty good.

They've been gone so long the area has done "skinned" over. Nuttin to play with leaves me so sad after yawning and stretching in the morning. Rob

Joe, thank you kindly for your return post but I do find this type of post in an open forum unacceptable. A private message would have been much better received as I do not run competition down and find the action unprofessional. We all enjoy this antique truck hobby and it brings us together with a common interest. You are welcome to participate as a member offering your services but if it continues to "run down" the competition I will ban you. Rob Swallows

I had a 20,000# truck on the 13,000# drop deck so not real heavy. It is difficult to pull it into any gear sitting still This feel like the shift rails are extremely rusty and trying to slide them through the bores. It is like something such as a sliding clutch gear is binding on it's shaft? This doesn't feel like there is mechanical bind as it doesn't matter if the truck is moving, or sitting still, engine running or not. I can spin the pto shaft by hand. A me and Jaime, (helper) can shove the truck by hand on the flat floor. Something is definately binding and it feels like something is not lubricated, or lubricating. I can't rememove the top cover with the trans in the truck so I'm thinking the next step is to pull it out to get a good look into the top and evaluate the rails, forks, springs and detent balls. I'm hoping the main shaft is not twisted but I don't know how that would have happened as I've not used the truck except to haul what I've mentioned. Rob

I'd prolly look really serious into installing a 300+ into "killer" and being easy on the throttle pedal. You like that truck so should be kept. Rob

No the PTO is out/disengaged. I drove about 30 miles today loaded at all different speeds. No out of ordinary noise, no vibration, nothing seems amis running on the road. Just hard to up, or downshift. Rob

Not a heat related problem. I was dragging my drop deck around with a truck on it. No difference cold or hot. You have to yank it out of year with such force you will pass through the neutral gate and grind on the next gear from the force. Rob

What a mess this thing is under the dash! There are air lines bent, and crimped all over the place. The actuator valve plumbing runs all over the place under there and the windshield wiper linkage pulls the shit outta the lines when operating. I picked up a couple new PP1, and a PP7 valve to just plain start over. Rob

Hey there, the 2100 series transmission in the R model is very difficult to shift in the gears. You really have to yank the shift handle to switch gears. It is nothing like a Fuller, or the older Mack transmissions I havce in any truck. Tonight I pulled the floor panel and removed the shifter and tower and the forks and blocks are very difficult to move with a screwdriver. I don't see anything wrong through the opening but something is definately binding. There is no way to remove the top cover and forks from the trans with it in the truck so I know it has to come out which I'll do prolly next week. Anybody got any ideas what could be the cause? It was easy to shift a couple months ago. The oil is full with Synthetic, and the trans is clean internally. Nothing is binding and grinding like a broken spring and displaced detent balls. Rob

In my own defense. I would never do that to a Mack as I could make use of the parts....... Rob

I hope OSHA doesn't see her on the jobsite without a hard hat or safety glasses! Rob

As Mike said there may be something wrong with the hub. I'd have the face of the hub runout checked about an inch outside of the lug studs. Rust build up can also not allow a rim to seat proper and a lot of stress is imparted when the lug nuts are tightened. This recurring problem has a cause and it could be overloading but four three wheels is cause for concern. Rob

I'm quite certain that is the way this job will go also. We will get into it a little tonight and see the bulk of what is wrong I hope. My shop smells like burnt brakes terrible. Rob

I was gonna take my ole winch truck out for a ride today but when turning around in the back yard, promptly got stuck. That was the end of that idea and the truck still sits there. It is going to be nice the next few days so I'll let it dry up a bit and get out there again. That drop deck is a little heavy with all the crap I store on it. Rob
