Looks good Matt,must have been a fun ride.

I've never been able to verify this,but this is the story I was told long ago.UPS was very fond of the H69.When they were told the H was being phased out,they ordered a whole bunch.In the meantime,they aquired a couple F model demostrators and liked them even better than the H models so they canceled the order and Mack was stuck with all theses H69 cabs,so they came up with the H81 & H813 heavy duty mixer chassis to use up the cabs

I only ever seen one picture of a h81 there a vary neet looking truck for sure.

That superliner looks so sad sitting there.

I'm still in the hunt for a Mack MB tractor single or tandem axle. I know these trucks are in most cases shot but hoping somone knows where one is sitting. The truck don't have to be in show condition just have solid sheet metal around the windshield and drip edge around top of cab and hopefuly have a title or some type of paper work to it . I'm looking to spend 2 or 3 grand depending on condition and distance from home. If anyone has any leads let me know. Thanks

Rudy

i knew an old timer would know. haha j.k sorry Mike

zinks dad been driving since the 50s and he always likes to talk about oil trucks and the one day he was telling me about the either balls he said they were like a paint ball you put one in that cap and there was a pin in there then you pushed down popping the ball letting a little either in for a cold start.

I guess the days of all mack departments are long gone. It will be a sad day when our 78 MB getts replaced. What make trucks has your dept been replacing the macks with?

Rudy

It's upside down. That's why it's all bent up. Very common piece. You should be able to find one in any junk yard in PA.

your right I never realized that it was upside down lol . I pulled one off a b61 I stripped but the realized it was real thin in spots.

Thanks for your imput.

Rudy

I'm new to this also, but make sure it has a title. One pricy thing on these b models are the wing Windows or vent Windows see what shape they are in because its going to take a few bucks just to get those redone. Like the other guys said look for the amount of missing parts also.

Rudy

Post a picture of it. We'll see what we have. Also what length?

sorry for the delay. The crossmember is 32 inches in with.

Dose anyone know if there are any companys still macking the rear crossmember for the b models im sure there were other model macks that used the same member, mine is beat hard no comming back for it. let me know if theres any thing out there or if anyone has a used one laying around. Thanks

Rudy

The jake brake from a older 673 would be same and i cant remenber the model.I think it is older model than 675 but dont remenber off hand. Not a 237 because the cam is different.

after I asked that question last night I found a thread asking if a 711 Jake brake would work on a 673 and the guys were saying the 2 valve engines used the same jake. Thanks for.your imput.

Rudy

i would deliver the parts in lieu of paying shipping. When you talk to Harvey just let him know. I will be heading up to pick up some equipment so I can grab what you buy.

My wife is from Easton so we visit family and friends often.

Pete

Thanks pete. I dident try calling today I don't want to bug him if he is busy. I will try tomorrow. Thanks again

Rudy

Can anyone tell me if there ever was a jake brake made for the 711 and if they did how hard would it be to find and install. Thanks

Rudy

We visit friends in Easton so if you're not in a rush I can meet you somewhere.

No im not in a big hurry i know theres a few other people looking for the fenders like i am. D you mean meet up as in being able to bring the parts down here or just to talk about what parts im after. Im about 15 min away from easton so yeah we could mmet up. Thanks

rudy

Call him between 9am to 5pm.

ok. I tryed calling twice today no one picked up so I left a message. He has the last 3,main parts I need. Thanks for posting this.

Rudy

Nice pics. I wish I could find a MB like that black one around where i live.

when would be the best time of day to call him

He owned several b81s so most of the parts will be for that I believe. When I get his permission I will list his number.

I could use some b81 stuff too. Thanks

Rudy

i think mine are the steel one`s.

don`t know if there`s much diference on that type of gaskets.

leon

Hey Leon I'm on the look out for head gaskets for my 711 also I'm going to stop by a local NAPA store that is vary good with finding stuff like that ill let you know what I come up with. Is there a short video on YouTube of your truck ?

It states on the application that you must be a member of one of the folliowing: ATCA, ATHS, SPAAMFAA or a chapter of SPAAMFAA.

ok thanks

Do you have to be a member of a truck club to come or just if your showing a truck.

Rudy

I see they filled the spot where my b81 was sitting.

Those first 350's were called a ENDT678 if I remember right,but shortly after renamed as a E6-350.First one I was around was in a '80 Cruiseliner demonstrator that our dealer was passing around to it's customers.

Superdog would any of the Mack v8s fit under my hood and would it bolt to my quad box. I was told it can be done but I would have to use a bigger radiator. Thanks

Rudy

a 237 is the ENDT675 Maxidyne engine,and while they will work with a Duplex,Triplex,or Quad,they were designed to be used with the 5 and 6 speed Maxitorque transmissions.One of if not the best engine Mack ever designed.

A 250 is the ENDT673C Thermodyne engine,rated at 250 hp,with a operating range of 1500 to 2100 RPM,these were better suited to the B model transmissions.

Most of the time,what's referred to as a "300" is actually the ENDT676 Maxidyne rated at 283 hp.These had a tip turbine fan and intercooler set up,andlike the 237 were designed to be used with the 5 and 6 speed transmissions.These engines were available starting in 1973.

An actual 300 hp engine was introduced in 1980-81 as the E6-300,this was considered an Econodyne engine,with the front mounted air to air aftercooler.

Thanks superdog for setting me straight on that, I guess if I go with a engine up grade I should look for a end673c those were turbo right ?

I'd think along the lines of the oil cooler like Superdog said.

Can't be a liner leaking a 711 is a dry sleeve engine!

Ron

Thanks Ron
