I don’t have spec sheet for the B421 but I saw one and it looked the same as the B42. I’ll have to get one so I can compare them side by side. Yoos’ has been repowered which complicates things.  Mike 

Yes ours came with an EN401 originally before being repowered with the EN414 (ala Chrysler 413 industrial). It still has the original baby quadbox in it though. Denton concrete roads out of Michigan bought ours new. They had a huge fleet of B421s at one point 

I was always told the 421 was the cheapest version. The one my brother and I have had zero options new.

I have the chance to buy a 1940 Mack ED model configured as a produce truck. Truck originally came from Brooklyn.

It runs and drives, the body is in great shape and everything is there. It is a survivor meaning that it does not need to be restored. My question is what is it worth?

Thanks

Big Robbie

Does anybody know any history or Vin on this truck other than what's mentioned here? I just bought the twin to it and trying to find out history on it. Thanks

I'm looking for a for a needle in a haystack. I'm in need of a hood for a Mack ED pickup hood in any condition. Thanks,  Josh 

Does anyone have a part number for a complete seat or the seat covers for the blue seat with the black diamond plate pattern cloth like used in the Granite and and Pinnacles. I'm looking to put some in my one superliner as they'd match the diamond tuck blue interior perfectly. Ps, I am well aware there are upholstery shops around. I'm looking for part numbers to try and get oem covers or complete seats.  Thanks

Very impressive!!

Could be injection pump cam shaft. Had that happen a few times 

They were very low production numbers on them. I'd have look to be sure on exactly the number. I had one which used for a donor to a superliner as it had lots of issues but I sold the cab to go on another cruiseliner v8. Both were WS722s. Mine was the first off the line, 001001.

The vin specific decal (white one) was like a paper based decal. My decal guy couldn’t replicate that exactly, but then again truck restorations are not judged on the lawn at pebble beach, so it is close enough. Decals were made by a local decal shop off of text messaged pictures with measurements. They turned out good and were fairly cheap to have made. We ended up replicating all the original information decal for the whole truck on a superliner restoration.

Wow those look good and definitely the right location for Wills truck for which he was asking 

Sure go on the door above the latch if I remember correctly. I'll look later

Here is the V8 for the Magnum restoration project. Built for me by the Osborne brothers in Wyoming.

 

Mike is good people. Help me out on some oddball engine bearings for my E9.

That was a 1941. No we don’t unfortunately. It was sold at our auction to the owner of Sidley Mack of Erie. That sat in their showroom for a while until they switched hands. If I think of it I’ll get some pictures of a few of the other antique trucks and post on here

Ok thanks for the reply

This was one of many antique Mack trucks that my grandfather owned and restored. Also the long time owner of Masterson Transfer. This particular truck had a tree growing up through the cab that needed cut with a chainsaw when my dad was sent out to see if it was worth salvaging. This truck was restored over the winter months at our main truck terminal in Warren, Pa

What ever happened to the Mack ED pickup. Do you guys still have it?

What ever happened with this Superdog? I'd be interested to know.

Sounds like typical 325 to me. Every one we have does that bobtail. Hook a trailer on and it's fine. I put a cable throttle on the one to cure it.

I know where that's all at. My lips are sealed 

Where this hiding? 

There was a factor V12 Hayward RS700 there as well.

I had my 1980 Hayward Superliner there.

You are right on with the RPM's there is a difference which I did not realize until now. These are the tags of the two different pump engines. Timing is different by 5 degrees as well. I do run the inline pump with a few more degrees timing than tagged and it does run stronger.

We do the same on the inline pumps as well. We set the timing just the same as a V pump. Runs much more gooder!!!

The idle should be 650RPM's for an E9. That said I just adjusted mine a week ago. I had a little issue with idle at 650 at start up and cold. Coming off the interstate and at temp it would be 500-550 and sometimes want to die at a traffic light for a few minute after. Turned the idle up to 725 cold and now 650 at operating temp.

The adjustment is the vertical screw, with lock nut under the throttle bellcrank on a inline pump. loose the locknut and turn the screw in contact with the bellcrank an 1/8-1/4 turn up and that will get you 75-150RPM. Retighten the locknut and done. Should be the same for a V-pump but I have to look on another engine to be sure. 

I think its 650 for inline pump and 625 for v pump. All my v pumps are 625 and have no issues.

I failed to mention this engine has a v style injection pump. Is the idle screw still by the throttle linkage?

 

Lol I thought of that after I posted. I was thinking V pump. Yes its on the side.

I have an E9 that idles around 450RPM and I am wondering what is the proper adjustment procedure? I think the low idle rpm should be around 750, is that correct? Thanks

The idle screw is on the side of the injector pump where the throttle linkage comes out. The proper idle setting is 625rpm.
