Hi, I personally prefer the look of tandem drive truck and would never turn a tandem into a single it feels to me you your taking the trucks credibilty away. Rigid tray trucks are fine as single drive, Prime mover style trucks just look correct with tandem drive just my opinon for what is worth all the best with your project Cheers Gearbox

I agree completely with what you're saying. A longer wheel base truck just looks alot better with 3 axels. If we can find parts to rebuild the power divider, we'll most likely leave it a three axel.

Thanks for your input,

Daniel

I'm not sure about the parts. If it were me I would contact your nearest MACK dealer. Have the trucks VIN and the serial number and part number off of the axle and the power devider itself. Barry , the site administrater can help you there. He works for a mack dealer. Check out the LINKS at the top of the page...he works for WATTS MACK and this site is owned by WATTS I think. Good luck

Alright sir, I appreciate the advice and the help. I'll be checking into that pretty soon.

Thanks, Daniel

I am no kind of an authority on the subject so this is only an educated guess. I took a coarse on firearms appraisal several years ago and the big emphasis was to keep the item as original as possible unless it had to be repaired with new parts for safety.Keep all the original parts...if possible. If you ever sell the truck it will have more value if it is it's original form. However if you do decide to change it over to a single screw try and keep the original running gear so if you do sell it ,it will be more valuable to a collector. Good luck and have fun.

Mackdaddy, Thanks for your input. If i do leave them in there, the mechanical power divider will nee to be rebuilt. Are the parts needed to rebuild them still available from Mack or anywhere else?

Thanks for your help,

Daniel

I,m in the process of restoring a 1963 Mack B-421 S and I need some opinions on how original I should keep it. So far I'm planning on leaving the original EN-402 engine and the original trannys in it, but i'm wondering if I should leave the original rear ends in it. They are Mack dual reduction bogies with 7.49 ratios, sitting on a 3 leaf walking beam suspension. So the question is, should i rebuild them & leave the truck stock or find a newer single axel rear end and put under it?

The truck is only going to go to shows and haul a few tractors around every once in a while.

Thanks for your input,

Daniel

Ok, spoke with the commercial guy at the scales. Sounds like the section is up to a little interpretation regarding what you might have. Get a hold of the Federal Motor Carrier Safety Regulations Manual (Title 49) section 393.67 (Liquid Fuel Tanks). It states that they're not prohibited but must conform to the section's regulations. I don't have the manual at my office but I'm sure you might find it on the web.

OK, Good. Thanks for your help. Daniel

Ya I'm a Chippy, I work on the Grapevine which is the I-5 corridor between Los Angeles and Bakersfield. I've been with the department about ten years and have been up on the hill since I started. I was pretty much born into it, my dad was a 37 year veteran of the department and I have an uncle who is a commercial officer in northern California. He started out in Central L.A. in the late 60's and moved us up to a small town called Glennville in the early 80's when I was getting ready to start grammer school. It was up in the hills and a great place to grow up, only had 131 people in the entire town. Mostly cattle ranchers were up there so that's how i got exposed to this hobby you could say. I latched onto one of the ranchers and used to help him gather cattle on the weekends and during the summers. Got my feet wet running heavy equipment with him on the ranch and was fortunate enough to haul cattle with him in his early 80's cabover Freightliner. Times have definitely changed even the short amount of time I have been on the job. People aren't as respectful towards law enforcement or even each other as they were some years ago. I think most of the younger generation feels they're owed something but that's got to be a reflection of how they were brought up. People seem to be in a big hurry to nowhere out here, it's definitely fast paced but I don't know any different having been born and raised out here. I've been to other states like Colorado, Utah, Idaho and such and everybody seems to be more easy going and not in much of a hurry. A much slower paced lifestyle, I like it much better but am tied down here with my job. I do my fair share of commercial enforcement don't get me wrong, but it seems like the majority of the truck drivers I end up dealing with are youngsters who have just started with some of the larger over the road carriers. They don't seem to take as much pride in their trucks as owner operaters and the pee bottles strewn about the shoulders of the highways is a sign of the younger generation who just don't care. I know there are quite a few drivers out there that don't care for us Bears out here but we're just doing our jobs like all the rest of the people. I can't speak for everybody but the majority of the people on my department do care about people and take pride in what we do. Enforcement is a critical part of the job and it does reduce traffic collisions. Nobody is ever happy to get a ticket so therefore someone's only experience with law enforcement may be construed as a negative one if that's there only contact with us. My goal every day I go to work is a simple one, not to write a bunch of tickets or take people to jail but to simply make it home to see my family, bottom line. Some of the best help I've ever gotten from passing motorists during situations has been by truck drivers. We need to work together since we're always going to co-exist. Times are especially hard now with the economy and many people I stop are upset thinking that we're "revenue rats" for the state. The fact is my department receives no revenue from any citations issued, it all goes to the local county or city. My department is completely funded by the vehicle registration fund, and since 1929 our department has always come in under budget every year. Not many organizations out here can say that. Anyway, I've been searching for other folk out here in my neck of the woods that are involved in the truck hobby but with "Macks". Needless to say there aren't many but that's ok, guess I'll have to represent for all you guys on the East Coast. I've had a ball working on this old truck and it has definitely been a good experience for my son. I don't see myself ever getting out of the hobby, it's become an addiction. with all of the research I've done I can honestly say that Macks are truly unique and no other truck manufacturer can compare with what Mack has done. I would like to get back and see the Mack museum someday and maybe I can drive the old girl back there with the family in tow.

Hey, I'm not too far from you myself. I'm about 20 miles East Of Lake Isabella, Past a little town called Onyx. I got a few Macks& I think I talked to you before about a Thermodyne & Triplex. Do you know if it is with in regulations to use aluminum saddle tanks for gasoline instead of diesel? Thanks for your help & good luck with your truck and your job. Thanks, Daniel

Hey, I just got the build sheet on my 1963 B-421 "S" & it says that the engine is an EN-402. The serial tag is gone off the engine so there is no way of telling if it has been changed out or not. Anyway my question is whats the difference between the mack EN-401 & the EN-402? I always thought that all B-42's had En-401 engines in them. Thanks for the help, Daniel

Where can I find a direct swap treadle valve for a B model. I don't really want to retro fit lines/fittings. Most of the newer treadle valves I have seen have 4 fitting holes, 2 on each side, were as the one from the B model has 3 fittings in back and 1 in the front.

Thanks

Try Watt's Mack. Daniel

Hey, I'm working on a 421 with the gas engine. Right now it has the original steel gas tank. I have two aluminum saddle tanks i was thinking about putting on it instead of the steel. what I was wondering was, would those tanks be OK to use with gas, or is there any laws that say you have to have steel tanks? Thanks in advance, Daniel

Hey everybody,

After along time of thinking it over, we finaly decided to part out our B-753 "LT".

It has the ENDLT 673 engine with the Triplex transmission. The engine looks physicly good, but may have some sort of internal problem as it will not turn quite all the way over. The transmission looks fine and as far as I know it is in good shape. The truck is dissasembled but complete. I need help though on what I should ask for the engine and transmission. If any body could help me out with that, I'd really appreciate it. Thanks a Lot, Daniel

Hey, anyone know what the front axel weight ratings are on a B-421 SX & a B-753 LT is?

Thanks, Daniel

Hey, yesterday I went and looked at a V8 Cummins naturaly aspirated diesel engine and a Brown-Lipe transmission. What I was wondering was what is the model of the engine how good is it and how good is the transmission. The only thing i could make out on the engine tag was the raised numbers.

This is about the order of them from top to bottom:

1789 V8 170

9-70 1214-00

3300 F048788

The guy said the engine has 470 CID. and 170 HP. It is 28 IN. wide & 44 IN. long.

The transmission is a Brown-Lipe

Model: 6352

Low Gear: 39.07

Serial #: T900157

If any of you could help me out with this, I'd appreciate it, Thanks, Daniel

Can't say for sure,but other axles in that "family" are rated at 20,000#

Dave

Dave, thanks for your reply. It'll help me out alot. Thanks A Lot, Daniel

Hey everybody,

I was wondering what the weight rating of a CRD-91 (single axel) dual reduction axel carrier is?

The serial number is: A14654

Axel number is: RADL 5151 ( it is in same place as the SWD# on Mack bogies)

I would appreciate any help. Let me know if I need to give any more specific details.

Thanks A Lot, Daniel

Try Watts Mack.

I sent the only one I had to them and got some made.

Barry made me a great deal!

Don't know where they were made, but at one time they had some, so I'm sure more are availible.

Give him some lead time and I'm sure Barry can fix you up.

As I remember, the cost was about $70.00 a pair.

I've been down this road, and this is all there is.

When you put those new ones on, you'll have a bit of old Wyoming on your truck.

Should make it run a little faster and ride a little smoother!!!

Packer

Ha Ha, for sure. Thanks for your help. That does seem like a real reasonable price. Thanks, Daniel

Iv been thinking about shortening the bed some, and putting up some poles and winch. I think that ol truck would make a cool winch truck.

Good Luck on your project. You going to put those aluminum saddle tanks on there?

Daniel

Hey everybody, I started taking the emblems off my truck today and one of my 421 emblems is that if you make the wrong move, it could break in half. They both need to be replaced or re-chromed. Is there any companies out there that sell or reproduce new ones? And also if there is anyone out there that has a set that they want to sell, I would be interested. If not, We can make these work.

Tank You,

Daniel

I tuned up the first Mack I owned and drove it home.

1959 B-421 with "Baby Quad" with over-drive.

Chained up the front axle, singled out the rear axle and got 5.5 mpg.

This is at 6,000+ above sea level, and some hills.

(Western hills!!!)LOL

So - - - no load, no tire friction, tuned up (new plugs, plug wires, re-built carb, and clean oil-bath air cleaner),and an easy shot home (49 miles).

Thought I did good!!

East Coast has all that air, so you might do a bit better.

Packer

Packer, Thanks for your reply. That is just about the mileage that I thought it might be. Thanks, Daniel

Hey everybody,

I was wondering if there were any companies that make aftermarket carburators that were more efficient for the EN 401 engine. Also does anyone know aprximately how many miles per gallon a stock EN 401 gets? Thanks, Daniel

I am in the same boat. I am looking at a 1961 B42. Will a 471 DD fit? Thanks

Dieselman, I have a 421 that we would have liked to put a diesel into, but we have not found an engine with more than 250 HP that will fit into it. Another thing you have to think about is how much cooling capacaty the engine needs. I do have some info that says that a 471 Detroit has 160 HP @ 2100 RPM., is 42 inches long, 29 inches wide, 42inches tall, and weighs 1780 LBS.There is a website you can go to that will tell you dimensions for Detroit, Cummins and Cat engines. It is:

http://www.adieselengine.com/new page 1.htm.

Hope this helps, Daniel

No.

All the B42 series were gas powered.

Ok, Thanks for the info, Daniel

Hello everybody, I have a a B-421 with an EN-401 in it. For the heck of it, I was wondering if they ever came from the factory with a diesel engine? Thanks, Daniel

They tend to "find" things at significantly higher cost a couple days after they inform you they sold the last parts in existence you needed just last week.

I've been very vocal to keep people from getting taken if I can help it; But only when I know for sure. The above example is from my own experience, with a strong second by another party.

Rob

Rob,Thanks for shedding some light on them. Nobody needs to deal with busunesses like that.

Thanks, Daniel

Hey, I have a B-421 with the same engine. I did find a place that suposedly has parts for them. Their website is jobbersinc.com. I have not talked to them about what they have or their prices. Rob did tell me before that I would be in for a surprise when working with them. That could be good or bad?????

Good Luck, Daniel
