Looking for an affordable Torque wrench.

Working on a dana 60 that needs 250 ft-lbs

My torque wrench only goes to 150. Also want to be sure it does left hand threads as well because i ran into that once.

Whats your choices?

Pinion nut needs 250 I'm guessing ?
Hell I'm going to need to wear a backpack with 80 pounds & hang my Dana from the ceiling to help torque that.

If yall will remember, you're not supposed to max out a click type torque wrench. I think the spec has always been like 20% from the max....somethin like that I don't remember exactly. But I know you're not supposed to max them out.

meaning that to torque 250 you need one that is capable of going to 300. which my newest (I hate to say it) Snap on does. also does angle, torque to yield and such. My older S/O clickers go to 200 and 250 respectively.
I also have another dial type one that is 600 ft/lb, and is 3/4" drive. plus a couple of 3/8" drive ones.

That's good to have. I always say with torque wrenches, it's good to have one......just one that will really get up there. Some of the pinion nuts, for example, have some of the highest torque specs on a car. Especially when a crush sleeve is involved.
 
HF torque wrenches are surprisingly decent, but now that I have a full collection of HF units, I've slowly started upgrading to digital units. I have a Gearwrench (before they were bought by Home Depot) digital 3/8" torque wrench, and I absolutely love it.

I used to be an instructor at a nuclear power plant. They actually had a procedure that did not allow you to use the lower or upper 20% of the wrench span. I thought it sounded wrong so I contacted Snap-On corporate and asked for the truth. The reply I got said that the wrench is good for the span of the wrench. In other words, if it starts at 40 lb/ft and goes to 200 lb/ft, that is what it can be used for. I never was able to get them to correct their procedure however as old habits are tough to change, especially in nuclear.

Prior to using a wrench on a work order, the wrenches all had to be verified accurate within a few percentage points on a load cell. They were also calibrated on a calibration bench every 90 days.

Thanks Jerry. I've never heard that from Snap On. I've always thought it was kinda stupid to make a torque wrench that could not be accurate for the entire span of adjustment.
 
Well I bought one of these the other day for doing pinion bearing preloads. I checked it against a certified calibrated wrench and it was pretty much spot on.
