MT2858 Issue

[pierre]

I just bought a MT2858 pitbull ratchet second hand. It was advertised as being brand new never used and it looked that way. No oil in the inlet, pristine condition, had no reason to think it was ever used.

Was a bit disappointed in the power. I tried to replicate what Matco did in the video - torque a nut to 90ft-lb and try to break it loose, didn't work. Tried it at 75 or so, still didn't. Used a snapon split beam style torque wrench.

Regulator set at 100 psi to make up for any pressure drop in the lines. It's a 3/4" trunk line ran across the ceiling, 1/2" drop, 3/8" hose for 10 ft. Using milton type V fittings. I don't think its an air delivery issue. What gives... is that video phoney or am I missing something? I just read a post here about breaking it in by running excessive oil through it and running it 2 minutes straight. I guess I coul dtry that. Thoughts?

I suppose the number one thing is, there is no proof that a tool is new unless you purchase it from the vendor. The video is not phony, but is performed under ideal situations. I would look into the exhaust port and remove the packing. I battled a Snap-on DA issue for a couple yrs until I realized I had a restricted exhaust port/

I had one of those "pitbull" Matco ratchets once. It wouldn't pull a sick cat off a commode. My fifteen year old Snap-On FAR72B kicked it's balls up in a tree.

Good thought, but there is no packing in the exhaust. The exhaust is a collar in the middle of the tool that rotates so you can direct flow. Underneath the collar is metal, no packing of any sort.

While a FAR72b may be better I'd still like mine to do what it did in the video. I was thinking about a 1/2" ID hose but end of video said 3/8" ID recommended. I guess I'll be calling Matco if the break-in routine doesn't make a difference.
