I'm considering a pneumatic impact wrench for the F40 tire hub nut. Does anyone have any recommendations, bearing in mind the hub is tightened to over 400 ft lbs
Alex, I have for years a Makita 110 volts with a 1 1/2" socket. the torque is 425 lbs and do always clean the hub and keep it DRY!!! I had the socket made here but Harbor freight sells a box full of big sockets -cheap price and quality- Roland F40LM
I bought a $50 dollar special from Kragen to do the special clutch nuts on the 308. It was a miserable POS - waste of $. Get the advice of someone who knows what is what with air impacts, or electric for that matter. Caution #2 find out what cfm your air compressor puts out at 100 psi and check the requirements of the "wrench". I think it will require a fairly big tank or compressor to feed it. hth, chris
that's why I went 110 volts, any hotels etc.. has an outlet even my generator can do it etc.I paid $750.00 in 98... Roland F40LM
Thanks Roland. That's good advice. I'm assuming that the socket supplied with car fits a standard size drive on the impact wrench. I've seen wrenches with drives from 1/2 inch up to one inch. does the F40 socket fit on the 1 inch drive?
Woahh??? Roland, I may have a dumb question here, but it's out of pure curriosity..... the F40 comes with a spare tire, how would one go about changing that by hand on the side of the road where help is of no avail ?
A pneumatic is an OK way to remove a torque specific nut, however, it can be hard on the shoulders of the nut as the pneumatic shock is more inclined to deform the metal, particularly where the torque is not completely controlled. In contrast, use of a pneumatic is not the best way to torque a nut, again, for the same reason: it's tough to measure and control the torque. The best way is to get yourself a 3/4" high torque wrench measuring up to 600 or 700 lbs and a four foot extension (requires application of approx. 100lbs at the end of the bar). You'll have fun trying to restrain the wheel movement in a safe and reasonable manner however... Incidentally, the F1 teams use pneumatics not because it's the best, rather, because it's fast, and, they have highly controlled (non-standard) pneumatics which are specialized to the application.
First, I don't have spare and such and I have a crew to help since my application is track only from day one.The car has inboard jacks. I had a custom socket made per car, to avoid the play on the nuts. and so far, I never ruined one, replaced or LOST one the road or track event. I'm using the Makita on all the race cars, from the P.super car, GTP, CAN AM MCLaren and done "thousand" wheels change and never lost a wheel!!! never used a torque wrench to check- no time-on single nut after impacting.The tool tells you by sound that you're tied,also call experience. I had to have the impact rebuild this past June after years of great services.($250.00) great tool. Roland F40LM
Alex, I don't know about stock tools. I know that FOD borrows mine when needed.During road rally, most of the time, I have my race trailer not far behind and I'm a lucky dude with always new Pirelli on the car.Good to have a generous sponsor! The LM has the size nuts than the stock but different from the TR Roland F40LM
