Balancer locking tool for the Mitsubishi V6

If you’re wondering why we are doing a post on this subject please read our post on why it is soooo important to correctly torque the balancer bolt on these engines.

The tool I have made suits a ‘99 model Challenger with the 3.0 24 valve engine however with a simple modification it should suit any model Mitsubishi V6. The Challenger has two holes in the balancer that aren’t threaded so it was necessary to weld the two bolts on the tool, however the earlier model Pajero’s and the like have threaded holes I believe so it won’t be necessary to weld the bolts, just use the correct bolt and screw them into the balancer to achieve the same result.

The tool is made from a flat length of steel, two bolts of different length ( to allow for the thickness of the steel ), and a bolt,nut and spring washer. Without being rude, this is what my tool looks like and it’s dimensions should you want to make one like mine!

The two bolts had to be welded in place for the Challenger as the balancers holes aren’t threaded, however check to see if your balancer has threaded holes or not before doing any welding.

The arm of the tool passes under the A/C compressor and rests of the chassis rail and holds well even with 180Nm of torque on the bolt.

Thanks - excellent article, works a treat.
I built one similar - You need to use 10mm high tensile bolts. I used 10mm x 50mm bolts and didn’t weld them. just locked them off with a nut. Use a couple of washers under one of the bolts to get them both the same length and your done.

Craig,

Your articles are fantastic as it is refreshing to get an honest and simple explanation on matters mechanical.
I have a ‘knocking’ sound coming from the front end of the engine in my Pajero 91 SWB, which is quite audible at low revs however the sound tends to lessen as the rev’s pick up.
Took it to several mechanics for an opinion but this ranged from ‘replace the timing chain - water pump - pully replacement - damaged sprockets - etc, etc..
No one was willing to pull it apart for a closer inspection - lack on interest in the job I would expect.
I don’t have much mechanical experience so I am wanting to get a sense for how difficult it maybe to inspect the balancer? Don’t happen to know any good mechanics in the Melbourne area, do you?
Cheers.
David
