Centerlock Torque Wrench
I need to buy a torque wrench for centerlock wheels. It seems Precision Instruments is the tool of choice, but there are 2 models, C4D600F and C4D600F36H. I cannot find what the difference is, they both seem to have the same specs, but the C4D600F is less expensive than the other. Does anyone know the difference, and which one I really need for this job? Thanks

I think the C4D600F is just the torque wrench
The 36H is torque wrench and breaker bar - two separate pieces.
You should never use the torque wrench to loosen the nut - always use a breaker bar.
If you already have a big breaker bar, then just buy the 600F.

Got it, thanks. Did not realize the less expensive kit did not have the breaker bar.

I don't have CL but when I need a torque wrench to do high torque activities I borrow a torque wrench from the local auto parts store for $0.
How many times do you take off your CL wheels a year?

I seem to recall reading that the breaker bar handle from Precision Instruments is quite a bit shorter than the torque handle. I know the torque wrench fully assembled is around 4' long. Isn't the breaker handle closer to 3' or even less?
I saw a YouTube video of some dude struggling to break loose the nuts with one of those. It seems to me that the breaker extension should attach at the point where the torque handle does and use the middle piece buy my impression is that it attaches at the ratchet head and is thus too short.
Finally... I've read that it can be difficult to detach the ratchet head from either piece.
With all that in mind, I ordered mine without the breaker bar extension and will get a 4' 3/4" breaker bar separately. They're not expensive.

FWIW, I just ordered this.

It's 40". Hopefully long enough to make the job easy.

I believe the torque spec on the CL nut is over 400 ft/lbs. Local parts stores generally don't have anything over 250 capacity. At least in my area.

The breaker bar that comes with the Precision wrench combo is extendable. It’s nearly as long as the wrench when extended.
