Dieselmeken shows how to fix leaking pump - dieselmeken - 11-14-2011 This is a small clip showing how you can do to fix leaking deliveryvalveholders while the pump is still in the car. Take care if you planning to do this operation http://www.youtube.com/watch?v=-SW1dRGpHPU Put a comment if you like / dislike it / Göran RE: Dieselmeken shows how to fix leaking pump - willbhere4u - 11-14-2011 I just did that on my 300sdl but I did it one cylinder/delivery valve at a time RE: Dieselmeken shows how to fix leaking pump - oel_brenner - 11-15-2011 Dieselmeken, thanks for the great videos! would love to see a MB "M" pump complete disassemble reassemble video explaining along the way. for too many people the inside of injection pumps is a complete mystery. I for one really appreciate your contribution to the community keep up the good work! RE: Dieselmeken shows how to fix leaking pump - George3soccer - 11-15-2011 Thank you goran. I don't know how you do it working and operating a camera RE: Dieselmeken shows how to fix leaking pump - cho - 01-06-2012 Thanks Goran, ... is this procedure same for MW55/320RS16 pump (300sd). regards RE: Dieselmeken shows how to fix leaking pump - dieselmeken - 01-06-2012 No mw serie is not like this. RE: Dieselmeken shows how to fix leaking pump - cho - 01-06-2012 (01-06-2012, 06:23 AM)dieselmeken No mw serie is not like this. thanks again, I need to change a d-valve also (because my car shakes a lot after complete rebuilt),not only copper washers,..so I have to let bosch guys do it..? cheers RE: Dieselmeken shows how to fix leaking pump - tomnik - 01-07-2012 before going into the ip first check the injectors. Compression is o.k.? Valve job done? Depending on what you define "shaking" you might want to search for damper screw (on the back cover of the ip). Where from Europe are you?

RE: Dieselmeken shows how to fix leaking pump - cho - 01-08-2012 (01-07-2012, 12:15 PM)tomnik before going into the ip first check the injectors. hi tomnik, engine has been rebuilt 15 days ago compr/valve is ok, 5 injectors pop at 125-127 bar,... yes,I have ordered rack dumper still waiting to come... (is it possible to change it without taking oil filt.housing off?) but few days before rebuilt I have taken pump to some bosch guys and they told me that my elements are worn a bit, and in some near future I have to change them ... do you or Goran have any experience with DTP MW elements (made in Germany??) over here I can get them 40e a piece ??? and my d-valves also had to be changed .... btw I'm from Serbia ... regrads ChO RE: Dieselmeken shows how to fix leaking pump - tomnik - 01-08-2012 Hi, rack damper can be changed with all in place. Are you sure you can get the small MW elements 1 418 414 001 from DTP? Your Bosch guy, can you trust him? There must be much to wear a diesel pump element (if fuel filter was in use and not too much red diesel was used). Are you sure that he can not adjust the balance of the elements? Take the pump back and install it. Then you turn the flange of cylinder 5 until idle is better. Wait until larger MW elements are available (6 months).

RE: Dieselmeken shows how to fix leaking pump - dieselmeken - 01-08-2012 Its not so that you have missed the overflowvalve so that you dont have any pressure in the pump? seems quite odd that the pump would bee worse after a test & adjust in the Boschshop. Have you timed the pump correct? Dont turn the barrel if you are not sure that you have the fault there. Do you have a turboengine and need aalot of power? If not you dont need any bigger elements, you just need a proper adjustment. Is the engine ok timed in crankshaft / camshaft? /Göran RE: Dieselmeken shows how to fix leaking pump - cho - 01-09-2012 (01-08-2012, 02:37 PM)tomnik Hi, as for bosch guys I can not be sure, because I have no knowledge at all considering IP technologies... I will try to take a pump to another shop just to cross reference data .... how large those elements are gonna be? I would like to stick with default turbo ... and maybe some 6,5mm el's ? (01-08-2012, 03:33 PM)dieselmeken Its not so that you have missed the overflowvalve so that you dont have any pressure in the pump? seems quite odd that the pump would bee worse after a test & adjust in the Boschshop. at first while they rebuilt it IP timing degree was 15 ATDC and I told them to correct it to default 24 BTDC. They adjusted it, but the shakes and noise stayed. yes,my engine is turbo but I do not need some serious additional power (maybe if I see that I must change elements then I can try with some power increase... but I m satisfied as it is now, in basics I would like to have this engine as long as possible...) proper adjustment over here does seem to be a science fiction because I can not find bosch guys with REAL knowledge. as for pump timing I can only suppose what they did ... no way I can prove anything as I have no basic knowledge about it... video taken few days ago: shaking OM617 no smoke morning cold start video: no smoke thanks guys (01-08-2012, 02:37 PM)tomnik Are you sure you can get the small MW elements 1 418 414 001 from DTP? nope, as I can see they offered only 1 418 415 xxx elements for MW pumps ..... RE: Dieselmeken shows how to fix leaking pump - dieselmeken - 01-09-2012 To mee it sounds like a balance problem. It runs on all 5 cylinders what I can hear. Maybee Tom has another opinion.

Maybee Tom has another opinion. thanks Goran, and sorry for stealing your post RE: Dieselmeken shows how to fix leaking pump - tomnik - 01-09-2012 I agree with Göran- balancing. (I mixed up the cyl. 5 issue with another post). Assuming that the pump has to go to a diesel shop for proper adjustment anyway, you could measure the glow plug voltage OUTPUT when the engine is running and the glow plug common socket is disconnected. In the socket (where the it goes into the glow plug relais) you can take the voltage (mV only) and compare the individual cylinders among each other. Then you carefully rotate the flange of the cylinder with lowest voltage. The other voltages will then change also but in general it should be better than before. This is not according to any correct instruction but can help. Can you check timing with a strobe lamp at a Bosch service to confirm what the guys did? Tom I have to do some more tests but the MW elements will be >6.5mm. RE: Dieselmeken shows how to fix leaking pump - cho - 01-09-2012 (01-09-2012, 07:06 AM)tomnik I agree with Göran- balancing. ..of the pump I suppose? (01-09-2012, 07:06 AM)tomnik Can you check timing with a strobe lamp at a Bosch service to confirm what the guys did? will do that and report back (01-09-2012, 07:06 AM)tomnik I have to do some more tests but the MW elements will be >6.5mm. that's great, If I m not wrong in that case I can hold my default garret turbo (maybe add some 65mm exaust...) .... what kind of HP can be expected in that case...? regards chO |
