How to Set Injection Pump Timing on Mack E9 V8 with Ambac Pump

Scrappy Merchandise is here! - scrappyindustr...
I made a little how to video showing how to set the injection pump timing on a Mack E9 V8 with an Ambac Pump. This method is similar to many other engines as well.

That’s an interesting engine, considering most US heavy trucks have in-line six cylinder engines. You just don’t see V-8 diesels that much now except in European trucks. The only V type engines that used to be popular in the US were the Detroit Diesels. The E-9 has a distinctive sound too.

Sam, you and Matt need to go on a trip with the bulldozer with grandpa’s with your grandpa’s old truck and it’s super dog and y’all should go to a job site. It would just be a cool video I don’t know if you’re really wouldn’t know.

[@williamspates1015]

Was yours a 500 to start with or a 445hp friend of mine has a couple heavy wreckers with E9 in them.

[@gordonagent7037]

I love the look and sound of this truck, I’ve seen you on Matt’s channel hauling stuff for him. Can I ask from an enthusiasts point of view, why does it sound like it has a miss, I know there would be a reason but I don’t know it. Maybe you have covered it in another episode, if so could you reference it for me. Love what you are doing with your channel, your content, commentaries and camera work are a credit to you.

beautiful truck and love the v8 power how come you had the timing so far advanced are you running bigger injectors and turbo or were you just seeing if it would make more power that way keep the videos coming of the mack!

[@ScrappyIndustries]

Thank you! I had it cranked up to 25 degrees trying to lower the EGTs. While it did help with that I did not like how it ran. I am running a borg 475 and marine injectors. It made 800 hp at the crank when I ran it on the dyno before i put it in the truck.

That sound E9... Beast

[@thepubliceye]

That looks like German engineering.

Nice truck beautiful engine 1 of my favourite all so notice it’s inter cooled is that original V8 super liners in Australia were never inter cooled to my knowledge

[@ScrappyIndustries]

Thank you! All of the E9s I have seen in the states have been air to air intercooled. I think the older ENDT 1000 was the non intercooled version.

[@tomnapier681]

I have an 85 ultraliner v8 its intercooled were the superliners different ?

[@shanewilson9115]

that was about the best video i have seen on a e9 timing

[@ScrappyIndustries]

Thanks for watching- I appreciate it

[@jcnajdek9735]

Beautiful! Very detailed on the timing setup. Thank you. What electronic fuel pump are you using?

[@ScrappyIndustries]

Thanks! It’s the 150 gph airdog raptor

[@shakespearloggingcowboy]

Looking for some wisdom and insight. Have a 1979 v8 Mack that doesn’t run right. Info on where to source a ambac injection pump would be great.

[@crawfordwhite8549]

Smart bloke and a very neat Superliner, worth a fortune here now in Australia, well done.

[@ScrappyIndustries]

Thanks 👍

You should put a mack air starter on her. Will set her off

[@ScrappyIndustries]

They sound cool for sure

[@FQP-7024]

not really familiar with trucks as much as i am with cars but learning these things makes me really want to buy one.

[@JensSchraeder]

Whats the torque rating on the E9 500?

[@ScrappyIndustries]

From the factory, the 500 hp units were 1660 ft-lbs. With the torque limiter cam removed and the fuel turned up this engine was closing in on 3,000 ft-lbs on the dyno

[@CMDSR]

Wow you caught the bar just in time. Would love to see pictures or video of her restoration.

[@timothymorgan8922]

How hard is it to remove the v pump.!

[@timothymorgan8922]

Idle jumps all over,and it's a pain in the butt to get it started,it sounds like it's trying to run away sometimes.!!

[@ScrappyIndustries]

I’m having similar problems lol I bought an inline P Pump hoping to install this winter. The pumps are not physically hard to remove. The problem with the Ambac pumps are parts are getting scarce and people who know them as well

[@timothymorgan8922]

@@ScrappyIndustries that's what I'm finding out currently,but if you can pull it apart,then I will be able to see what's there.i hope.!

[@3406Accert]

Why don't you address the truck in it true name the Superliner ?

[@ScrappyIndustries]

What’s a superliner?

[@tallyman15]

Nice clean engine. She sounds great. Love a V8.

[@carlwilliams1570]

Nice Dog! Good work!

[@ScrappyIndustries]

Thank you!
