I saw a post somewhere that someone used this to remove the harmonic balancer on a Mercedes M112 engine, and the place to place the 1/2 inch breaker bar stripped so it was not a good experience for me. I'll give it 3 stars since it was not built specifically for my engine so its on me that it did not fit. But the stripping of the tool that is supposed to resist over 100 ft lbs of torque on the bolt is not on me.

I had to use a hammer to gently tap it into place. Worked great. Used an ARP bolt at 100ftlbsThis was on a triton 2v but basically all ford harmonic balancers are the same. Very good tool I'll be able to use many times.

The box says for Ford/Mazda, but works perfectly for some mercedes engines too. Was able to replace my front main seal without needing to remove my radiator fan. Held up nicely, fit was perfect and doesn't weigh alot either.
