Info Injectors and Trigger Points

Good morning, everyone,

next week my overhauled original Bosch injectors should arrive from a specialized company located in Germany. I have to mount them on an engine M110.983 (W116). I also bought the original Bosch grease to grease the trigger points....do you have any suggestions for me for changing the injectors and disassembling and reassembling the distributor? Is this a complicated job to do yourself or is it better to go to a professional company? 

Thank you very much...greetings to all 

P.s. next year I would like to be with you at a workshop of the always mythical Dr. Djet

Greetings

Hi Claudio,

well it is still time to join my 10th workshop on coming weekend. As 2 people decided on Monday to wihdraw, we can welcome you.

For injectors renew sealings in cylinder head. Carefully remove rests of old sealings and then use new rubber sealings. Also check all other fuel hoses. After mounting trigger points and installing ignition distributor you have to adjust ignition timing and verify at idle, 1500rpm and 3000 rpm and also vacuum retard. Therefore you need a stroboscope. Afterwards adjust idle rpm and idle CO. If you have no exhaust measuring device, go to a workshop and let them measure. Then adjust by clicks on ECU rheostat.

Hi Volker....I would love to attend your workshop, but unfortunately I have to work this Saturday. (I will try to arrange next year).

Regarding the injector gaskets, I bought all  the original sealings from Mercedes.

Unfortunately, I do not have the strobe lamp, so for the timing work I will have to go to a workshop that has it. In the meantime maybe I could buy Norbert Fischer's "tool" to measure the distance of the points and find the distributor sealing....I have to figure out what code it has...

Thank you very much Volker

Hi Claudio,
think about buying a strobe lamp.
It isn't too expensive - maybe the bill of the workshop would be a similar price.

Sorry for the stupid question--maybe it can be helpful for people like me is would like to get to know their car a little better. On the Mercedes M110.983 engine how do I check the ignition timing? where are the "marks" that I need to check? do I have to disassemble the valve cover? sorry again for the question

Thank you

Claudio

  

Hi Claudio,

unfortunately there is no M110 D-Jetronic manual. But removal and installation is the same for K-Jetronic distributor. So check jetronic.org/de/107sl-wsm/107sl-wsm-cont...107sl-ri-engc-m110KA ? chapter 15-510. Or if you have W116 workshop manual it is chapter 07.5-510 .
