10mm Element Thread
10mm Element Thread
This thread will be to document my adventures with 10mm elements in my spare MW pump. Hopefully for the benefit (or amusement) of many.
The pump:
found in the front seat of a 300d at my local pick-n-pull. They only charged me $30 for it! (after haggling)
The elements:
The elements that I bought are for a Bosch pes6mw100/320rs5 which apparently comes on some sort of Volvo. The Bosch part # for the elements is 1 418 512 201. <-- incorrect part number! correct ones below.
I bought my parts from the Chinahanji parts plant. This took several emails back and forth with the sales person, and about two months from first contact until the parts actually arrived. The elements were $12.50 each. Shipping was about $56 (from Fujian province, China to California, USA).
I would recommend that folks who buy elements from china consider buying one or two extra parts. The guy that installed the parts mentioned that one of the elements was sticky. Made me glad that I bought 6 instead of 5.
The shop:
The only shop that I could find in my area that would work on the pump was Pacific Fuel Injection in South San Francisco. The owner is pretty friendly, but seemed skeptical that it would work out. He offered to turn up the pump and not rebuild it, but I insisted that I wanted to give the elements a try. The turnaround time was about a month. He preferred that I not discuss his pricing with others.
surprisingly, he was able to calibrate it so that it is actually delivering pretty close to spec for the stock pump. So right now the pump is turned way down. My plan is to get it running, confirm that it wont run away, then work on getting the engine more air, then start turning it up. He said that he set it up so that I could turn it up myself by adjusting the throttle stop. btw, I asked him about internal linkage binding problems due to throttle stop adjustment. He said its not a problem.
the install
what a PITA! I didnt realize that you have to remove the oil filter in order to change the pump. I wasnt able to get it done over the weekend. Hopefully I can wrap up the install this week.
the results
hopefully awesome...
Edited to show correct part numbers:
the elements have the Chinahanji part number of CZ-B415 019, bosch part number is 1 418 415 019
Sounds good. Everyone that has been thinking of that project has been told the 10mm element's stroke is different.
Tom has an external full load lever adjustment that shouldn't affect the linkage.
Keep us updated on this project and take some pic's a Holset xy or hy should work out nice with a built pump and support 25-30 psi no problem
There are two different types of 10mm elements, "thin" and "thick". The ones found on the cummins are the "thick" I believe. This is for the MW pump.

I moved his post into a seperate thread :

I have a sheet that the guy gave me that shows quantities at different operating points like; idle, full load, full load w/ pressure on the alda, and breakaway. Ill have to look at it again to see if it has what you are asking for. Also, I have pictures of all this stuff, but the forum wouldnt let me upload them. Ill try again tonight.

That indeed is big.

(10-02-2009, 01:28 AM)DeliveryValve ^^^ So is that the thick or thin elements?

Sorry, I was planning to explain the sheet a bit better but forgot.
The printed columns on the left, numbered 1-5 correspond to the fuel amounts delivered for each cylinder at the different operating conditions. The guy said that the variation was within the acceptable limits.
the handwritten numbers on the right are the average quantities (over all cylinders) that I would get by turning the throttle stop screw in by the number of turns indicated at the top of the column. He provided info for 1,2,3 and 4 turns.
Yeah these are the "thin" elements.
Looking at the difference in mass between the 5.5mm and the 10mm elements, it would seem to me that the 10mm elements would use/need a stronger return spring, compared to the spring requirements for the 5.5mm elements, to maintain the same high RPM capability as the 5.5mm elements.
Do the stock 10mm element IPs use stronger element return springs?
How much power do you estimate this pump will support??? very cool project take some vis when you get it running!!!
5.5mm can pump 760mm3, 6.5mm 1062mm3, 10mm 2514mm3.
3.3x the static displacement of the stock elements, or, FAR more power than the engine could ever contain.
The 7mm Myna can support around 450hp on a 5-cylinder.
sweet!!! I need to save up a bit I guess
o.k. now it's more clear. I got confused by the handwritten numbers.
All the numbers are with governor?
The pump only numbers would be interesting to get an idea of how the governor settings have to be reduced to flow the required amount. That would give the reduction of the governor range. In case the usable range gets too narrow the governor might not work properly.
When do you have the IP in the car?

You can remove the pump without removing the oil filter.
Wow is all i have to say, very nice upgrade, please let us know how everything turns out to.

AAWWWWW!!
seriously!? So I didnt have to go through all this? what is the trick? the manual that I am working from said that it had to be removed, and it looked to me like there wasnt enough room to get it out.

The M is cake to pull with the filter in place, its got plenty of room behind it. I had to remove the filter to get my MW out though.
Before I went ahead and pulled the pump (MW) when I was doing the swap to the M, I contemplated pulling the filter housing - I even bought a gasket. But seeing the glass half full, instead of half empty with a big freakin hole in the bottom, I tried to pull the pump and was successful. I can remember reading about FI's experience with the oil lines and didn't want a repeat. The worse that could happen is I don't get the pump out and I have to pull the oil filter.
I didn't have to take anything off the pump itself, other than that stupid lower rear bracket (argh!!!). I just finagled around with it until it popped right on out. There is a very small window which it will fit out of, but it is very much worth the time spent jiggling the pump around to find it to avoid pulling the oil filter!
On topic... AWESOME mod!! I'm anxiously awaiting your results.
BTW, put a new gasket on the IP!!!! I didn't and had a 1/qt per 100 mile oil leak that only occurred at speed. It of course happened while I was 500 miles from home.

The compression spring is the same for MW55 and MW100 (1 414 619 014). At least it is used in all MW55 and some MW100
This is the element assembly of the original MW100.
The spring looks pretty strong. Don’t have the pic or dimension of the MW55 spring.

the pump and oil filter relocation stuff are bolted up. I need to time the pump, fill everything with oil, hook up an egt gauge, and fire it up. I have not obtained the fittings that i need to hook up the turbo oil supply, so I removed the turbo, and will test without it for now.
friday will be a furlough (wrenching) day for me. I hope to report on how it runs (if at all) on friday.

keep up the good work!!! please take some vids when you get it running!!!!! and good luck!!!!
I woke the neighborhood up this morning with a healthy dose of raw, unmuffled diesely goodness
I am happy to report that it idles, and does not run away. But there are a few issues.
The idle is kinda rough. I noticed that after I shut it down, there was some wetness around some of the injector lines, so I am hoping that its caused by a leak, and not the pump.
There seems to be more smoke at idle than there should be. But then I did time the IP without a drip tube, and its only at 24 btdc. Im hoping that I can clear up some of the smoke by advancing a bit.
There is also a definate hesitation when moving the rack off idle. The engine really boggs down for a while, even if I carefully ease on the throttle. Not sure what to do about that. Could that be a timing problem too? Ideas?
I took a video of it running. I will put it on youtube and link it here shortly.
EDIT:heres the vid http://www.youtube.com/watch?v=bI-vmoQX_AI I think all the racket scared one of my cats. you can hear it meow loudly right at the end hehe.
Also, here are some pics of the oil relocation stuff in case anyone cares about that stuff.
"There is also a definate hesitation when moving the rack off idle. The engine really boggs down for a while, even if I carefully ease on the throttle. Not sure what to do about that. Could that be a timing problem too? Ideas?"
That is the Idle Governor. It is over counteracting the ever slightly increased engine speed. If you increase the throttle until it bogs down and hold it, will it come back and bog out, come back and bog out, etc (searching)? Then if you continue to gradually increase the throttle will the cycle get faster until the engine takes off and revs up?
If yes, it is an Idle Governor oscillation (in your case radical searching), the Idle Governor can be adjusted to achieve a better balance with the internal throttle spring and bigger elements. The idle Governor is over adjusting (over compensating) with the larger elements.
Some adjustments to the Idle Governor and Throttle and you should be fine. You are in uncharted waters, if this is the only issue you are having, I am very excited!
BLOODY AWESOME! Bravo. On a side note, these engines would sound beautiful a supercharger, tubular headers and a straight pipe, no turbo to soften it. With this kind of fuel available, it would be doable. Can't wait until you get it back together! Do let us know how it drives, and what happens when you start turning screws under the rear cover.
There is no possible way the engine can handle anything remotely close to what 10mm elements can pump out. Myna's 7mm pump supports 450hp on a 5-cylinder, 10mm elements can pump a hair over twice that amount of fuel.
Depending on the rebuild cost, and the longevity of the Chinese elements, one could save about $800 over buying a full myna setup.
