If it were any other engine it would be $10,000 or less in the condition its in. A good investment for trucks sake.

Any updates on this? Im planing on doing the same to a 1985 Mack Mh with the e6 motor and was thinking of swapping in a 2180. Im a fan of an all Mack driveline myself but I learned to drive on an Eaton 13 speed and I can confirm that they just won't break.

Thanks. you'd think it would surge at idle but it doesn't, it was the best starting diesel I remember. its only when it doesn't have a load on it that it surges.

Yeah that was my first guess was a governor issue. But the jerkiness is like a random misfire, I wouldn't think it would be a fuel supply issue because it goes away when you have a heavy load on it. Also do all Mack transmissions use the same bolt pattern? Because I think it had a mack t2090 and it's ok but it shifts kinda rough and top gear was always hard to get into. I want to put a t-2180 into it instead of putting money into that 9 speed.

1. We sold it for $1000 so buying it back might not be the issue (unless my uncles have gotten real attached to it). The money is really going to go into parts. 2. I never remember the speedometer working so I'd guess maybe a half a million? I never looked down at it 3&4. It's a farm truck but I might do some 100+ mile grain trips with it. I don't think the jerkiness is from sticky linkages because It doesn't happen under load, Air rated fuel maybe?? and I can get the brake petal off no problem but it's the actuator that you can push down put it won't pop back up. Ive worked on It for days with no luck before.

It ran and pulled pretty good when we had it besides the the no load jerkiness. The pump might need to be looked at but it's just a Bosh pump that was in everything in the 80s right? And what's the best way to get parts for these old Macks? since I don't think Volvo's still supplying parts.

Here's the first picture I found. Another thing I remember about it was that it had a bad leak in one of the rear bags with the air ride. Are these bag's specific to Mack or are they a common part? We've replaced some on a sprayer a couple of times, not that big of a deal once you have it jacked up right.

We sold our 1985 Mack Mh to some cousins a couple years ago, didn't think I'd miss it but look where Im at now. Anyways I was thinking of trying to get it back from them someday and fix it up a bit. But it's got some problems that I hope I can learn how to remedy here, here are some I remember: 1. I was jerky when it was unloaded and it almost seemed like it was starving for fuel but once you got a load on it it was fine. Governor maybe?? 2. Leaky rear wheel seals. 3. Motor (e6) might need to be rebuilt. 4. Stop engine light sometimes came on even If all the gauges were fine. 5. foot brake wouldn't pop back up and probably more but I can't think of them right now. I just thought Id compile some info before putting any money into this project. Any literature would help too! Im not in any big hurry I just really like talking and learning about these old Macks. ill try and find some photos of it and post em here whenever I can. Thanks

I have used this sight to find info on Mack trucks for awhile now and I finally decided to make an account. We had a Mh on the farm when I was little and I loved it, It sat for a couple years before we sold it to some cousins and now we kinda regret it. Anyways it needs some things and I was hoping to learn about it here. Thanks
