ETB1005 v8 engine

[BGarofalo]

I thought I'd share the new piece to my Mack collection. Maybe you guys have some more information on this engine model for me as well.  I picked up this engine to add to my inventory and it is actually a bit more interesting than I anticipated. By the looks of it I don't believe it has ever been in a truck.  As you can see in the picture it has a build date of 8/1976 and the engine serial number is 113. Now some of the parts on the engine are dated 4/1976.  It has factory block off plates on the compressor and power steering holes.  No pitting on the manifolds and it appears it never had a fan. Were these engines with that early of a build date put in trucks?  What does the B stand for in the model number? 

Side note: its not letting me add images...

very possible was a marine engine

I have one of the 142 1005's in my Superliner according to the Mack Museum..... the 400's were the later models. My truck was ordered in 1979.... and for all intents and purposes, it looks just like an E9.

What is the engine serial number on your engine? Is is painted the gold color originally?  I'm curious as to why if there were only 142 of these engines they span 3 years. So the engine I just bought is number 113 and it was built in mid 1976? 

Amybody have a tip for me posting a picture? Keeps telling me error. Never had trouble before.

It basically is an E9, second generation so to speak. The different horse powers of the ET1005 engines is all by different size turbo's.

Here is a list of all the E9 type V8's

The ET1005 and the ET1000 were all built in the same run, personally I think the production numbers are wrong and more were built than shown.It was also in production the same time as the ENDT865 ans END 866.

As for the photo it may be too large a size to post.  If you want sent it to my e mail and I can most likely post it.  PTCHESHIRE@JUNO.COM

The tag is missing on my engine's valve cover.... is there another place to look? It is just sort of a gray color... to my knowledge, it has never been painted either, and I've talked to the original owner....

According to the Mack Museum, my truck was originally destined to be a Maxidyne 1005 fitted with a 6 speed transmission, but at some point during the build Mack contacted the buyer and stated the need to upgrade to the 12 speed because the truck was going to be equipped with an intercooler and higher horsepower (a fact the original owner confirmed).... Perhaps one of the first chassis mounted intercoolers Mack utilized.... there are notes (I believe) on the original line ticket alluding to this alteration. Mine may well be an E9 after the fact and NOT one of the 142.

Interesting to note here the F735 is the Model number for the 1005 cabover I presume, at 353 and 360 horsepower. My truck model number is RW736 @ the 400 horsepower rating.

It's an EM9.  Mack changed the EM9 to E9 in the early 1980's. no changes to the engine only dropped the "M" .  Should be a greyish/greenish color. I believe if the power pack was up graded on the assembly line it would still have the number designation for the original engine ordered.

The don't think the production numbers on the ET and the EM series are correct, to low IMO.

The B in your  ETB1005,should  indicate  your  engine  is equipped  with the Mack Dynatard engine brake. Al  

[Yoos Brothers Construction]

The one in my 1980 RWS721LST Superliner tri axle is an ETCZB1000. My engine tag is gone as well but I got this off the right front pan rail. An interesting thing on mine is that it has a the number 142(I think off the to of my head) welded to the block in about 3 inch numbers above the starter. The engine has never been out of the frame. The truck only had 52,000 original miles on it when I bought it. I've never seen such a thing on a E9. Also my injector lines are routed completely different than an E9. Mine has never been painted. It has the original red orange engine paint that Mack used in 1980. The history of these engines in the early days is fascinating to me. I have a picture of a R735S tri axle dump that my Dad looked at buying in the 80's. It was a test truck with the ET1005 in it with a 6 spd tranny. Also there is a cement plant in Meadville, Pa near me that had one that was tri axle dump as well. Both of these did not have air coolers.

[BGarofalo]

The engine serial number should be on the passenger side of the engine on the oil pan rail. You will see a flat area. I would have to agree with 41Chevy, I think the number built is wrong. The timeline with the engine build dates just doesn't line up. Aside from a few differences they are pretty much identical to an E9.

I got it started last night. Ill try to post a video.

Interesting to see the shift in nomenclature from the 735, 736 1005's to the more common (numerous) 721, 722 E9's ... my truck is indeed a 736 and like yours, a 1980 as well.

Two filter set-up there... before the ESI engines were introduced.? 

 

I lifted this photo from the web purely as a reference for my truck... I assumed it is the same tag my truck should have had originally. This tag is on a 1983 RW721, and still called a 1005 at that time.

The tag says 1980 though. Mine is a 1000 not an E9 and is a 721 not a 736. The few 736 I've seen all had 1005s

That would be cool to put in a 1976 R700 or just keep as a display engine. I've only ever seen a hand full of 1000/1005s. The build numbers I have for the trucks which had them were all very low so the numbers might be right. I know that Mack only made 8 R735s with the 1005s and 9 F735s with the 1005s. I have the build numbers for the RWS/RWL 736 Superliners  here somewhere. Give me a minute to find them.

[Yoos Brothers Construction]

Ok I found it. According to the list I have from Mack, they only made 2 RWL736s and 4 RWS736s between 1979 and 1980.

Maybe the nomenclature changes once the after coolers become standard on all V8's... because the 735 1005 engine was not aftercooled and the 736 was... All 721-22's were intercooled correct?

[57 bcr]

Two spin on oil filters meant it was an ESI. Three spin ons meant it was an ESI +. Very interesting  thread on deciphering  these early  Mack   "Big Block" V-8's!   Al

If the ET series V8's  were after cooled  the designation by MACK would be 1000A or 1005A.   A  designates air charge cooler.

Don from the Mack museum provided me the build info on the V8's. and after we talked he revised it by adding the import V8's as they were sent to Australia and France. Which explains the Renault COE that I saw in Paris with French Bulldog across the front!

[Maxidyne]

Interesting reading- Looks like the V8s were big sellers in the 70s then faded. I remember reading in one of the magazines that before Renault offered the V8, Mack was only building two a week. Would be interesting to see the numbers with all the exported V8s to Renault, Mack Australia, etc. included.

I  believe some of  the turbocharged  864's were twin turboed,correct?  Al
