I just bought a Coleman Powermate Air Compressor with the idea of using it to remove and install tires; to dust off the air filter, engine area, and cabin area; to air out water from crevices after car wash; to inflate tires, etc... I opted for this model because of it's portability (only 20 lbs.)
I tried to remove the wheel nuts yesterday, but the impact wrench could not untighten and tighten the nuts with enough torque. I was hoping that I didn't have to use the tire wrench just like the tire shops.
The air compressor has a maximum pressure of 70-100 psi. The impact wrench has a max torque of 250 lbs at 90 psi. I regulated the pressure at 90 psi when I used it. There was no air leakage. The Helms manual indicate that wheel nuts on the Ody are tightened at 80 psi and I thought the impact wrench should be able to do it, but I still used the tire wrench and turned the nuts almost a full turn to make it tight. I'll be buying a torque wrench to see how tight is 80 psi so for now I used the common sense tight gauge.
For my setup, is that usual that I still have to use the tire wrench? Or, is there something wrong with my setup?
Thanks.
