Ausmack1 Posted February 13, 2022 Share Posted February 13, 2022 Hello new to the forum I have been watching videos of the injector cup replacement on the volvo d13 mp8 and notice they use a graphite paste on the injector while I think in Australia they use a washer. Do u need to use paste aswell as the washer? Which way is better? Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted February 13, 2022 Share Posted February 13, 2022 I believe it depends on if it’s the new style conical cups/injectors or not. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted February 13, 2022 Share Posted February 13, 2022 yes you do... if you have copper cup's, the new kit will come with conicle cups and the injectors will have conicle seats.. do you have the Swagging tool to remove and install the cups? jojo Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted February 14, 2022 Share Posted February 14, 2022 you need to use a long 8mmx1.25 tap coated with grease to cut threads into the old cup then use a slide hammer to remove it. any loose threads that fall into the cylinder are expected to be burned up and spit out. there are 2 long wire brushes and a long stemed tool that accept's rollloc' brisstlebrush to clean the bores. there are also plastic cups to put in the injector bores to keep any debris including bristtles from the brushes from getting into the fuel galleries.. my point is... if you have not studied this procedure and do not have the tools to do it right.... you need to stop! do I need to continue with the whole procedure to remove/ and re-install the cam, and then the valve adjustment procedure?

Ausmack1 Posted February 14, 2022 Author Share Posted February 14, 2022 Thank you Joey for the information. I have bought all the proper volvo tools to do the job I am a qualified motor mechanic but I have never done cups on a mack before I wanted as much information as I could get before I start the job. What sealant do you use for the cups I have read that loctite 620 is good ? And the graphite past where would be the best to buy that?

Joey Mack Posted February 14, 2022 Share Posted February 14, 2022 yes and there is a primer that goes on the cups before install. Its good that you have the skills.. and the tools.. if you have access to 'Impact' you can print the book.. I did some years ago.. I myself stay away from these jobs in my business, because I do not feel comfy doing them outside of the dealership. and without PTT to check my work when its done... jojo Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted February 15, 2022 Share Posted February 15, 2022 when you buy the injector 6 pack it comes with the correct cups. the engines head accepts them.. jojo Quote Link to comment Share on other sites More sharing options...
