sprtkr1 Posted May 28, 2016 Share Posted May 28, 2016 I've got a 2008 Pinnacle with the MP8 485HP motor. I'm removing the EGR cooler to have it cleaned. I know I'll have to remove the turbo to get it out. One of the bolts on the back side where the turbo mounts seems almost impossible to get at . I want to separate the turbo without disturbing the VGT box to get at this bolt. I noticed there is a tamper proof seal on the band clamp where the intake of the turbo attaches to the exhaust side of the turbo. Easy to remove this seal, BUT if I do take the clamp off and remove the intake side first to get at that bolt will I be hurting anything? Thanks for any insight on this matter. Mike.

Macktech689 Posted May 30, 2016 Share Posted May 30, 2016 You do not need to remove anything from the turbo to loosen the inside bolts, get a long wrench or "hook" 2 wrenches together. Keep in mind the inside of the mounting flange is slotted so the bolts just need to be loosened not removed.

sprtkr1 Posted May 31, 2016 Author Share Posted May 31, 2016 Thanks for the info. I do appreciate it. Didn't know they were just slotted. Every bolt on this repair has been a battle, but I'm winning.

RDOTC Posted June 3, 2016 Share Posted June 3, 2016 If you follow the electrical out of the vgt control on the turbo it with go to a plug. I unplug those to get the turbo out of the way completely. Ratchet wrenches with flex heads work pretty good for the back bolts. I always pull the outside bolts then the rear front bolt and spin the turbo to help loosen the bolts in the rear rear if that makes sense.

turckster Posted June 3, 2016 Share Posted June 3, 2016 I use a snap-on bent handle fine tooth ratchet. It works perfect for getting to the back bolts on mp7 & 8 engines. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45406-turbo-removal-on-mp8/#findComment-335325 Share on other sites More sharing options...
sprtkr1 Posted June 3, 2016 Author Share Posted June 3, 2016 Thanks for all of the ideas. I've always said I know just enough to be dangerous. That's why I only work on my own trucks. These are great ideas and I appreciate all the help !
