Rack Limiter instructions
Rack Limiter instructions
Hi could anyone please give me detailed instructions and possibly pictures on how to remove the rack limiter on a benz diesel? any help is appreciated.
You need to take the back cover off the IP and rotate the top cover (or remove) so you can get into the top of it also. Then you just loosen the the nuts (9mm, 13mm, 19mm?) and push the limiter inside of the pump and dig out with a pen magnet.
From FI's post
Full Load Limiter Removal Procedure
An exhaust temperature gauge (pyrometer) is necessary for reliable long-term operation of the engine after this modification. Do not exceed 1250°F in continuous operation or 1400°F in short bursts (under 5 seconds). Do not use any kind of sealer on any of the gaskets.
1: Remove the oil-filter housing. This is optional, with a long screwdriver its very possible to adjust everything with the housing in place.
2: Remove the pump back plate including shut off actuator and rack damper.
3: Disconnect the vacuum device linkage and tubes. Remove the top lid screws, turn the top lid (or remove both the ALDA and top plate for best access).
4: Remove the limiter's screws and nuts.
5: Push the limiter from the adjusting screw into the inside of the pump.
6: The hardest part is "digging" the limiter out of the bottom of the pump. A pen magnet is strongly suggested for this step. It can only exit through the thin slot on the top of the pump. You have two options- You can turn (rotate) the parts around inside the pump or you can punch out the guide pin the limiter used to slide on. The pin is no longer needed.
7: Once the limiter is out replace everything back in reverse order minus the limiter. Remember to use a new oil filter housing gasket and get the filter housing and block mating surfaces surgically clean. Be careful not to drop any gasket leftovers into an oil channel. If you get an oscillating idle this is a good place to replace the Rack Damper bolt with upgrade unit (upgraded one is gold anodized, the old silver in color) in the back plate of IP.
When you are done, you should have 5 or 6 parts left over (depending on the removal method you chose). DO NOT DISCARD THESE PARTS in case you decide to revert the operation at a later date.
what is the most notable benefit to this mod? more topend?
If you read the bosch manual, you'll realize you don't need to remove it...
You just have to adjust the governor properly.
Waaa

You read the Bosch manual for the pump. I can't link to it because it's copyrighted and pirated, but it tells you everything you need to know.
We're also very very close to having some documentation on what-all everything does as well.

havnt heard about that one yet. anything you can do to stave off the whole exploding mess?
(07-01-2011, 07:15 PM)300D50 Yeah, there's one sure-fire way to mitigate it.
Don't turn them.

well ya, i thought you did the rack limiter and full load together. did someone say you shouldnt? or are you just pointing out that you definantly should to make sure its been said? because thats ALWAYS a good thing to do lol. because some times people "in the know" that are trying to help forget to mention things that people SHOULD know before messing with stuff lol.

if you were to tell me the propure procedures i would be greatful, seriously! i want to learn all about IP's, and how to tune them.

I've also ordered BOSCH's "diesel fuel injection" manual, so we'll have moore soon.
OM616- i was NOT kiss'n your a$$, or trying to stick my hand out. i am more than happy to read the bosch (or any other for that matter) material all day long. i just dont know where to find THE STUFF THAT IS RELEVANT AND IMPORTANT!
if you directed me to a link, instead of just info dumping i'd be more than happy.
and how can you get mad at another enthusiast for saying "i'll take all you can give me" when i'm clearly simply trying to learn about this same stuff !?!?!?!? so that in the future i can give back what i recieve?
but it's ok, just keep making fun of people
Er, we just posted the link to the doc...
No need for a flame war guys, OM616 is just apprehensive after being roasted by a former forum member.
yes, and the link was HIGHLY appreciated!
and i dont roast, i just hunt for knowledge! so school me all day long lol
Who gives a flying F**K who roasted him.... That member is no longer here.
If you don't want to post or don't have the time to then don't tell people that you know exactly what to do!!!! And get them excited, then them 'em hanging
I was under the impression that he just needed to gather info that he already had, and just needed to post it. I didn't know he was writing a book. I didn't know so much work was involved!!! I don't want anything for free and I WILL NOT KISS ASS FOR IT.
I share anything that I know freely. I DGAF if forced was gay and tried to flame me for it. I have thick skin. I feel it is my duty to share here as much as possible in trade for what I have learned by using this site. Yes I have a personal life, you think I want to spend all my free time here? Hell no, but I will use my free time to answer someones question, no matter if it is educated or not.
Sorry we bugged you OM616

Yeah, I was being a bit lazy and put off editing it for a while... eeek... I'll go bash my head in with a turbocharger now...
No, I am plenty thankful for his work and knowledge and everything.... It just seems that He/You are being so bitter and harsh towards the rest of us, for something Forced did. Thats not cool. I am sure that anyone here is willing to do work to get answers but if they were already had, then what could have been done to help?
The main point is, a "turn this in by X turns" guide won't work. It's not the nature of the beast.
It's like saying that every gun barrel, ammo choice, windage situation, distance situation, and person can use the EXACT same scope/sight settings.
Indeed, bosch doesn't give you a step-by-step for adjusting either, their own training material (can't post a link, but it's out there) just says to dial it in on the bench, till it meets the test plan, keeping in mind what each adjustment does.

I was writing an essay, but I'll keep it short.
Sorry you feel that way. I don't understand why you do, still. I don't think anyone takes information for granted here; I don't.
This is the only forum I have found that I like. Which one is your "home"
(07-06-2011, 02:41 PM)smoke026 We are not merely remotely close to anything really "RACE" related on this or any other W123 sites, so why are people so PISSY? I mean, fuck! 15-18 sec 1/4 mile runs are still SLOW. The w123 cars will never be fast enough to get into pissing matches about. This is beginning to remind me of the DUCKS in high school who would fight over their Cold Air Intake Kits and their 5 ft spoilers till some one pulled up in a 400HP car.
This is not a High End Custom Underground "earn your stripes" vintage Mclaren F1 forum. ITS JUST W123's!! YES, THE CARS WE BOUGHT FROM GRANDMA ACROSS THE STREET!! 8)
All of these W123 forums are full of arrogant caulky OM617 Experts who hold the key and holy grail secretes to making 50 more HP..WOW! Congratulations, your cars are almost as fast as my Dixie chopper lawn mower.

CIDvicious had some pretty good rants about the same thing - if you really wanna go fast just swap a v8 in there. To me, that's giving up. Honestly for 3000-4000 bucks you can get yourself a myna pump, kkd manifold, bigass turbo and an intercooler, and have a pretty damn fast Mercedes diesel. The fun part about this site is the every man mods that can be done cheap and in the driveway, while we drool over the people who put the money, time, and money into their cars like jeemu, Rudolph, ect.
I saw this somewhere else but I think its true - its a lot more fun to make a slow car go fast than to drive a fast car slow.
Well Said guys
I am in complete agreement with OM616. He went through alot to create that document & the moderators probably did alot of work editing it. Now, yall are whining & pissing that you don't have specific directions & basicly insulting him? WTF??????? You SHOULD be kissing his ass. I never really understood how the IP truly worked & now can visualize the whole works. I call it ungrateful. Grow up !!!
Ed
Here is the picture of the rear of the pump with cover off.
I can do it later tonight or tomorrow. Or you could look at FI's pic and do your own
sweeet! as soon as you do CA (if you do, no pressure) i'm going to save it, make it my desktop back ground, drink 100 redbulls, stare at it for 3 days and memorize it all then drink 100 more and go to town on my IP. lol.
I "might" "might" be able to get my hands on a cut away display pump.
I have taken all of my previous post down because I feel that my sarcasm was too harsh..My bad to all that it may have offended. For the record, I have not personally requested any pump info on this site. Thanks for posting the follow up pics though as it may help any who may choose to tinker with theirs. I will not be touching my pump. Just not worth it.
Cheers, and again, no hard feelings.. I will stay away for a while..
Smoke, you are a better man than most. Please feel free to tweak your pump & then maybe a turbo upgrade to realize all that is possible with your stock IP. You may just get addicted to it & go for STD mods to your pump.
I'm sorry for adding fuel to the fire, I didn't mean to snap at anyone.
Like I said before, i'm stressed and was in a bad mood when a lot of this happened, not that it's an excuse for any of it.
I think the big issue is text doesn't, and never will, transmit sarcasm, inflection, or tone very well.
There's no need to stay away Smoke, I think we all realize there was a big communication gap scenario going on between all of us, and we worked it out.
