I want that serpentine setup!

[@cerwin21]

Nice info and video, thanks. Need a video on the Alda adjustments for running different altitudes. Mine failed and I got your alda delete part

[@doomsdaydiesel]

That's actually mentioned in the FSM. I don't remember exactly what it says but I think it says it will compensate for altitude automatically. There are 4 springs inside that can wear out, so once they are shot, they're shot. And to my knowledge, there are no replacement parts available.

nice video Joe! honestly kinda sketched out to run tht pump now lol after all the work I put in on this build itd suuuck for that pump to grenade

[@doomsdaydiesel]

I've never had a problem with one, but others have. I believe they'll notify you audibly when they are in need of repair/replacement/deleting though from the stories I've heard.

[@ILivethepositiveway]

@@doomsdaydiesel ahhh yess the legendary "SHUT ME THE F**K OFF" noises

[@wadehaley1112]

When does the serpentine belt setup come out

[@doomsdaydiesel]

It's out

[@coachgeo]

what Hg range should the OEM pump be pulling? That will give us an idea on what Hg to look for in aftermarket kits too.

[@calebakullian1437]

Wait a minute! Where did you get those pullys!

[@doomsdaydiesel]

I make them. They're on my website.

[@2000freefuel]

Is there a way to rip up a dry sump pump drive off the vacuum pump drive?

[@mattsimonson953]

What's the link to the electric audi pump you recommend?

[@doomsdaydiesel]

Thanks for the reminder. I knew I was forgetting something! Check the description again.

[@mattsimonson953]

@@doomsdaydiesel Thank you!

[@2000freefuel]

When I worked on an OM617 UNIMOG swap years ago I got to see a MB OEM part number cover plate for the Vacuum Pump delete. it was a stamped steel cover.

[@doomsdaydiesel]

Ya, they exist. NLA. And not tough enough to weld a pulley/accessory mount to like mine, hence the reason I made mine.

[@2000freefuel]

@@doomsdaydiesel ah yes I see that watching the video again, is there a way to make a shaft PTO for that mount? I'm interested in knowing how a dry sump could be setup for this engine.

[@dondaughtrey7537]

So I am buildintg a OM617 for a Jeep, with power brakes. I should probably keep the vacuum pump or is it a good idea to delete it and get brake boost from somewhere else?

[@doomsdaydiesel]

Hydroboost gets the win if you're pushing huge rubber. Otherwise stock pump or a Hella pump will work fine as long as you have a proper sized reservoir

[@dondaughtrey7537]

@@doomsdaydiesel can you send me a link were go get those items? Google search seems to send me to get make up!

[@doomsdaydiesel]

@@dondaughtrey7537 I have a link on the Vacuum Delete webpage which is linked in the description

@@doomsdaydiesel Notice the hella pump out of stock. Sigh. no biggie, will get it eventually

[@doomsdaydiesel]

@@dondaughtrey7537 there are tons of different models. That particular one has a very close part # that is slightly more output.

[@xsiaze]

do not ever delete the vacuum pump if you have w123/w126. Climate controls are running on vacuum, door locks, trunk lock, etc. I've never heard or seen vacuum pump to release ball bearings into the engine and cause catastrophic failure. I have 10 years experience in om617, and my dad has 40 years. Never ever heard of this so you must be trippin

[@doomsdaydiesel]

You have to replace it with an electric pump or you'd have no brakes. It will work just fine that way, and there is no longer a threat of your mechanical pump wiping out the engine.

[@xsiaze]

@@doomsdaydiesel there is no thread in first place bro, dont try to scare people, like i said in 50 years total of experience in my family on om617, never ever heard of that or seen it.

[@doomsdaydiesel]

@@xsiaze I never said it was common. Just that it's typically catastrophic when it happens. And that's not even the point of the video. The point of the delete for me is for customers swapping 96-04 V6 Tacomas.

[@xsiaze]

@@doomsdaydiesel thats why I said if you have om617 in the original w123/w126. For swaps, u could do whatever with this engine. But still, these vacuum pumps never fail with catastrophic engine failure bro come on, have u ever seen it?

[@doomsdaydiesel]

@@xsiaze ya, join a 617 facebook group. There are lots of people who've experienced it.
