MACK MAN

I recently bought a 1926 Mack AC,I want to change the oil in the 4 cyl gas engine.The engine is not filtered.The question is do I use a non detergent oil or do I use a detergent oil?A few guys tell me a detergent oil in a old engine will cause problems,and some say go with the non detergent oil thats what was use back than.Also should I go with a multigrad oil or a 30weight? Thanks AL

The Superliner in St Louis did not go to AZ,I bought the truck before Christmas,I drove it home ,the pump problem was a real easy fix shut off cable was stuck.The truck ran like a new truck,super nice shape the inside was like new.no holes on the dash everything worked like new.The price was real right for the truck was under priced,the guy mad a few bucks but I feel like I got a great deal,he was happy and so was I. AL

Its a M 32 I taked to the about a months ago and he gave me the Vin off the frame, Thanks AL

Added a 1926 AC to my collection,the towing company moved it 3 miles to my buddys truck so we could load it,thought his old tractor was real cool that he used to move it.I was lucky my buddy had a trailer with a inside with of 103" the body on the old Mack is 102". Al

Anybody know of a good insurance company for my old trucks? I have been with Condon and Skelly for 15 years,called them today to add a 1967 Peterbilt and they told me no more trucks.They said I can keep the ones I have with them they will grandfather them,but they will nolonger do trucks or add truck to a policy. Thanks AL

Ok I have a 1989 Superliner,its on neway airride.The truck started to have a real bad front end hop.I dont feel it in the wheel or in the seat,but at about 50 you can see the front of the truck hopping real bad,when bobtailing,it seems to go away at about 68 mph,but is still there not as bad.If I put a empty or loaded trailer under it,it is not as bad but still there.I took the truck to Tulsa auto spring,they have been around for years and I have had good luck with them before.They told me the rear tires were out of balance real bad,they need 40 oz.They balaned the tires and it was alittle better.I went out and bought 8 new Yokohoma rear tires and had them balanced,still hopping.Tulsa auto spring than put a stright edge on the front tires and told me one of the tires was out of round,put 2 new steering tires on it,still hopping.I have replaced the u joints,all new shocks,kingpins,still hopping.The truck spent 2 days at Tulsa auto spring and they keep saying its a tire balancing problem.They balance them on the truck and the tires only take 2 to 4 oz,still hopping?They found a bad u bolt so I had them all replaced,still hopping any suggestions??? I thought it might be the front spring hangers,but they tell me that they are fine. Thanks AL

I have two questions,I have a 1964 B 53 its on budds wheels,steel.I want to put aluminum wheels on the front axle can I get new wheel studs for the aluminum,the longer ones are they all a standard stud or a Mack special stud? I want to put some high flotation tires on the front axle size 385/65/22.5 the parts place whats to know what offset I want or need? I called 3 tire shops and none of them can help me has anyone put the big tires up front and have any idea what offset I need? Thanks AL

I have a 1989 Superliner,I have had the truck about 8 years.The truck is on neway airride,I use it everyday,pulling a flatbed run about 55,000 miles local a year,loaded one way come back empty.Anyway double frame,right at the end of the 5th wheel plate at the rear,the inside frame has a crack,it is on the top side of the rail.The crack is only on the drivers side,leave it alone?am I asking for problems?I took it to a frame shop in Tulsa and I have used these guys before and think they are real good and know there stuff,they told me leave it alone.as long as its double frame I will be ok,no need to get into alot of money and time. Thanks AL

My 1964 B-53 has steel bud wheels on it I want to change the front axle over to alum buds,how a big of a job is it ti remove the old studs and replace them with the longer ones for alum? Thanks AL

I love my Macks but I remember this truck from when I was a kid in Yonkers N,Y.The owners of this truck were right up the street from my uncles towing company,and they were more like family than just friends.Anyway its a 1963 Autocar DC-200,cummins 320 supercharger,5 main 4 aux,100,000 lbs rears,10 ft wide at the rear. AL

Here's the deal I had a wheel seal replaced on my 1989 Mack Superliner,right front drive axle.The shop that did the work was about 200 miles from the house.I get the truck home and look and oil is pouring out.I take the truck to my local shop,they pull it apart,for some reason the shop that did the seal put white lub on the spindal.Ok I have the seal replaced,new CR seal,drive it about 25 miles,oil pouring out.I take the truck back,they replace the seal,new stemco seal,drive the truck 25 mile,guess what oil pouring out.I take the truck back,replace the seal with a new national seal,here we go again 25 mile oil pouring out.I go back they replace it with a new national seal,I get about 3,500 miles look at it today and oil is pouring out.They have checked the hub 3 times it is ok,also checked the axle spindal,races and all bearings all ok.Called Mack and they told me CR has a wide seal and this will slove the problem??I have never had a problem with this truck in years,seem like since the seal with the white lub I can't keep a seal in the truck.The seal numbers have been checked and rechecked by 2 different Mack dealers.Anybody ever have this problem??could it be a bad run of seals??Also replaced the air vents on the topof the axle. Thanks AL

That Mack is in Phoenix AZ,its is still being used as a matter of fact they have two of them.The trucks are owned by Mid-States trucking.I was out ther a few years back,I bought some B 53 Macks from them and they were getting the two big Macks ready for a job hauling a load to someplace in KS. AL

Glad you enjoyed the show, Rob! It was great to meet you and we really appreciated all your help. Everyone seemed to have a good time despite the heat, and I really enjoyed sitting around the shop with all the guys talking trucks and telling stories in the evenings. We received several calls and emails saying they are looking forward to next year and so are we. For those of you who have never met Rob, he's a stand up guy and also very handy to have around - from setting up tables to mechanical repairs on our gator. Every show should be so lucky to have a "Rob" around. Al and Tamie

I have a 1989 Superliner with Neway air ride,what should be the ride height,I am taking the measurement from the bottom of the frame to the top of the axle housing.I have asked 4 mack dealers and got 5 different answers. AL

Trying to get any info on a Cummins Engine the plate on the engine has these numbers 1072276. The Plate on the chassis reads HRB1 91517 H6627B Need any info horsepower?? Thanks AL

Can anyone help me,I am restoring a 88 Superliner I am going from a single exhaust to a duel exhaust,the exhaust is not cab mounted,it is mounted to the steel uprights,air-ride cab.I am needing a VIN number from a daycab Superliner or at least the last 6 digits so I can order the exhaust elbows,my dealer says they can't help me unless I have a vin from a twin stack day cab air-ride cab.Any help would be great. AL

I have a 1989 Superliner the truck was a singal exhaust tractor.I am making this truck a duel exhaust set-up,I have got the steel stand brackets,for both sides.I have mounted the exhaust brackets,instaled both left and right mufflers and gaurds.To me it looks like the mufflers sit high,but looking at alot of Superliner photos and Mack sales books that I have they are right,I also had a 1985 and a 1990 Superliner so I know they are mounted right.Can anyone tell me, it looks like Mack uses a 90 degree elbow comming out of the mufflers.Does this run under the cab,or do they use a Y-pipe behind the cab?The way I have it now is there is a Y-pipe under the cab.I have to order the 90 degree elbows, it just seem to me that the elbow would have to be very long to get down to the top of the frame to match up with the Y pipe.Any help or any pics of this set-up would help. Thanks AL

I have a 1959 Mack B81 with an END 673. Pulled out the dipstick today to check the oil and found antifreeze. I pulled off the valve cover and definitely have water in the oil. According to the Mack service manual, it could be one of several things. (1) Defective oil cooler core (2) defective water pump oil seal (3) blown head gasket. I've always assumed water in oil was a blown head gasket. Any advice? There is no additional guidance in the service manual to determine which of these three things it might be. I hate to pull the heads off if its an oil cooler core - anyone have an idea to figure out which of these it might be? Thanks, Al
