Hit the end of the road for these stock 5.5mm elements. Already turned up the full load screw and messed with the torque capsule as much as I can and retain an idle that comes back down. She gets to 60MPH in the 9sec range and does 2nd gear brake stands so it's *improved* compared to other slow poke Benz's but it's time to really light the fuse. I've got an HX35 staring at me with a damaged compressor wheel; a billet wheel upgrade and rebuild kit sounds fun but will do me no good without the additional fuel.

Can anyone comment on personal experience? Looking to have my injection pump upgraded with larger elements and external ALDA. It looks like the options are to send it to the UK (DPUK), Sweden(Dieselmeken), or have the parts installed and calibrated here in the US(in which case I could get elements from either). Does anyone here have a say in which source is best for elements/parts? I know there is some animosity between those two for *reasons*. Anyways... located in the Midwest if that helps any.

So far the only USA based builder I've stumbled across with any backing seems to be BenzForce. Can anyone speak on experience with this company?

I was going to send an '85 MW IP from an OM617 to Dieselmeken to have their 7.5 elements installed.
Erik at Dieselmeken recommended that I use Benzforce to install the stocked 7.5 Diesemeken elements to save time and shipping expenses.

Last July, Benzforce completed the work in about 3 weeks, and I should be installing it in 'Desert Rose' before 2020 rolls around.

Dieselmeken (when Goren was still at the helm) built the "M" pump on Mutt the Race Truck. EXCELLENT piece. The dyno showed approx. double the HP for under $1K USD - a BARGAIN.



I briefly met Eric at Bonneville as he was guest driver for my buddy Steve (Salty Frog Racing) and his Dodge Rampage w/OM604 (IIRC) Mercedes engine. Nice guy and I'm comfortable that Dieselmeken is in good hands going forward.


I'd be comfortable with Dieselmeken.

United Diesel Service in South El Monte, CA is excellent and have years of experience rebuilding injection pumps and other diesel service including Mercedes. The owner is Justin. About 6 months ago they were featured on an episode of Wheeler Dealer rebuilding a pump for a 300TD wagon. They have a website. (626) 579-4832.

I've now heard a few good reviews on Benzforce installing Dieselmeken elements. My only curiosity is if the parts are still warrantied for life through Benzforce as they are when sold/installed at Dieselmeken's facility.

I suppose a call is in order to figure this all out. It seems as though this is the route I will be taking to save time and money on shipping to a foreign company.

Do they have any experience with pumps outside of stock specification? Leaning heavily towards BenzForce as it seems they already have the large elements in stock, ready to go. They're also a little bit closer as Cali is other side of the country. Not that Texas is *right next door* but it is closer by a good margin and this package will be at least a little bit large/heavy and will likely need to be insured shipment wise.

I had another forum member here tell me that his recent experience with United Diesel was...less than stellar. Something along the lines of "being featured on Wheeler Dealers went to their head".

This comes from a person that I trust and has much more experience with the OM61x engines than I do. Fwiw, I would not go with United Diesel - dieselmeken and benzforce both have a better reputation from the research I've done and the things I've heard.

Just my 2¢

After speaking with BenzForce a little bit back and forth, I've placed my order. He's got some cores in stock as well which means my car won't be down for a bunch of time while I wait for it to be built. Paid for a core charge up front to be reimbursed when mine is sent in after the swap.

Went with 7.5mm elements calibrated to 140cc governor wise with the aftermarket external alda limiting it a bit further to 120cc to start with. Should put me in the 300hp range with the ability to hit 400 should I find the airflow to burn it all. I'm thinking some nitrous could be fun... VERY EXCITED right now

I have known Justin, the owner of United Diesel for years. He has done work for me both on my 617 Mercedes Diesel (including the injection pump) and my Duramax pickup and always high quality work at fair prices. Justin told me that the volume of their Mercedes business jumped about 30% since the airing of Wheeler Dealer. They have been in business since 1945 (Justin took over the business, along with his sister, from their father). They do a lot of contract work primarily with local fire departments and charter bus lines.

California diesel injection shops supposed to abide by BAR rules. Weather that applies to older mercedes I dont know. That is unless they work under the radar. Big cloud diesel smokers are not looked upon well here.

I often wonder how long before they stop renewing our cars registration. They're already doing it with diesel trucks.

After using them for 32 years as a contract vendor I can no longer recommend this vendor .

The woman who's usually in the office is mercurial to say the least .

They charged me $500 to re calibrate my old I.P., it didn't work well .

There's a Diesel rebuilder in the S.F. Bay area that's usually very popular here, I'm not impressed but no smoke and decent power, just dropped the fuel economy by nearly 10 MPG .

CA is just bringing diesel vehicles registered at 14K lbs or more into compliance. All 1998 and newer model year diesel vehicles under 14K lbs have required a smog check since 2010.

This is aimed at diesel fleet vehicles racking up tons of miles yearly. I doubt (hope) they'll do anything to the pre 1998 diesels, as they represent such a small percentage of diesel vehicles on the road in CA.

More specifically those trucks with commercial registration that are 2009 and older can replace the motor with a 2010 or newer engine or sell it out of state.



I have a personal bias against this because Ive seen it screw a few rig welders and small private contractors over.



All those 1st and 2nd gen F450s and 550s 7.3s gone, and those trucks are solid workhorses. Maybe I'm just old fashioned but I'm not the least bit interested with what they're putting out today.
