Nice RAD gun .. Very common ..
You guys work too hard Nige ... Never done a track bolt in years .. Thats a dealer track program job.
That was us checking that the dealer had done the track bolts correctly. We've had too many bad experiences of re-shoed tracks loosening bolts in the field. How they can do that when they have a plc-controlled Cat Track Torque wrench in their shop beats me. But then again they probably don't have anybody who knows how to use it correctly TBH. A bit of a Catch-22 really. I don't trust the dealer to do the job 100% correctly and honestly would prefer to do it all by ourselves (if for no other reason than to save the hassle of transporting tracks to & from the dealer shop), but right now I just don't have enough manpower.
Mitch. Each RAD gun comes with a chart equating the air pressure to the torque it will achieve. Basically just hold the gun so it's free to rotate and squeeze the trigger. While the socket is rotating set the air pressure to the necessary value. Stop the gun, apply to the first nut, squeeze the trigger, and let go when the nut stops rotating. Repeat for all the others. One person can tighten all the bolts on 2 tracks (300+ bolts) in less than 2 hours.
JDOF. The RAD gun in that picture is a RAD model 4000, capable of 4000Nm (3000lb.ft.) of torque. IIRC we paid about $5000 for it. Basically the gun, air pressure regulator, & hose all come in the black carrying case you see in the photo.
