tjc transport Posted Monday at 04:01 PM Share Posted Monday at 04:01 PM 2 hours ago, Mark T said: I aquired a T880. Bought it to flip it. It needed a little help here and there. It's a Paccar with an Ultrashift 13. I drove it around a little , and there;s no debating it's a pretty nice truck. Keep in mind, they make better appointed trucks than this particular one, and even at that it's hard not to like it. Haven't been in a newer Mack, so I can't really say much about them, but that T880 is a pretty nice dump truck. Mine is on Primax and it rides unbelievably good. I'm all for traditional trucks, but if this is what there is to choose from now ???? I could adjust. the ultrashift is an ok trans...but no good for trailer work. it has a semiautomatic clutch in it. when you step on the brake it disengages the clutch. stepping on throttle engages the clutch. so when you are trying to spot a trailer using both brake and throttle it very quickly tears the clutch out of the truck. my friend had 4 of them.. for 3 years. and put 4 clutches in each before getting rid of them the allison is a true automatic trans. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

I bought it off of a farmer in jersey for 800 and it had a seized up motor, It was old but everything looked like new, Not even a rock dent or a spot of rust on the 14 yard Heil body. I bought a 450 out of a state truck from Donny and Bobby Metzger when they were in a barn up at Street Rd and 611 in Warrington. Bobby had long hair like a hippy lol. (Donny and Bobby are Coopersburg KW now) I think I gave them 500 for the motor. I put the motor in using the hoist in my grandmothers barn. It cost me as much for tags and insurance as I had into the truck That thing was such a good reliable truck, nothing ever broke But it was no speed demon lol It looked just like this one but the body was red my first ride was a 49 L190 single axle tractor with the 501 red diamond and quad box. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

I could see that. They'd be less than ideal for blacktop or anything requiring lots of stop and start. In soft ground, they'd be lousy. I think they do ok if you're on the highway a lot.

From sometime in the 60s until the mid 80's Mack offered a clutch that ran in an oil bath. I think it was a 13.5 inch two plate. Different bell and trans bell, seal between the starter drive and starter motor. (Different nose), and the clutch was actuated by an air cylinder. In the cab instead of the regular clutch petal there was a regular treadle valve, just like the one for brakes. When you looked in ,, it looked like you had two brake petals.

Joey Mack Posted Monday at 07:31 PM Share Posted Monday at 07:31 PM I worked on a few of those when i was a new guy. It think UPS used them and the post office too. I think in MH cab overs.. all i remember was the gaskets for the bell housing and starter, which i think was air start. And i think the oil was dexron 2 tranny fluid.. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74921-1996-pete-with-a-3412/page/5/#findComment-565600 Share on other sites More sharing options...
mechohaulic Posted Monday at 07:47 PM Share Posted Monday at 07:47 PM UPS did run the wet clutch. one customer (while I was at Mack ) did have a F model with wet clutch. took some getting used to. basically a treadle(brake) pedal on the floor. adjusted properly ; light pressure pushed the linkage.

I was thinking universal tractor fluid, but you are probably right. Whatever you do, don't let a rebuilder touch the starter. The dingleberries always loose the nose. And they are big money. They'll hand you a starter that looks right, but oil will pour out of it 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74921-1996-pete-with-a-3412/page/5/#findComment-565602 Share on other sites More sharing options...
