203 ft.-lbs?? Do I need to buy an impact wrench or just beef up??

How in the world do I get my strut-to-knuckle bolts to 200 ft-lbs?? There's no way. My tq. wrench only goes to like 80 and I've never seen one that goes past 150. Should I tighten them as tight as I can with a breaker bar and then drive carefully somewhere like discount tire and give them a little cash or something? Thanks...

Just for ref: where I work, we have torque wrenches that will go to 2000 ft/lbs. Course, you need to attach a 3' long extension to the 3' long handle(i.e., 6' of leverage) to use these wrenches.

I would say for the few times you will need a wrench of this scale, it would probably be cheaper to have someone else do the work. A wrench of that size will go for about $400, if you buy a quality piece(i.e., Snap On, MAC, or Gray).

my 1/2" wrench goes to 250 ft/lbs. i'd just tighten it up real good. if you've wrenched much you ought to have a feel for this.
where i work we have torque multipliers that go 1000ft/lbs and all you need is a 1/2" drive ratchet to make them work.

what happened to using a leg off of a swing-set?

I agree fully. Torque it a function of force (pounds) multiplied by a radius distance (feet). If you can't make the pounds on a 10" wrench, make the wrench handle or breaker bar longer. Achieving 200 Lb/Ft on a 10" breaker bar would require a lot of Wheaties, or about 240 pounds of pull (we all know that we are supposed to PULL, not push a wrench at high torque, right?). Accomplishing 200 Lb/Ft. with a 36" pipe slipped over the wrench would require only about 67 pounds of force. Even my eleven-year old can do that.

The edict for the day is WSNH - Work Smarter, Not Harder.

ODB,

What? What did you say? I can barely hear you over the scream of that triple-7 that just went over.

Why waste a pefectly good swingset? We all know they make an excellent spare engine stand, not a cheater bar.

Regarding lengthing the wrench handle, yes, you can do that, but just adding a cheater bar over the handle of your TW, will not get you what you want, the TW will still "click" at 150ftlbs, even though it takes you less pulling force.

What would need to be done is attach a 36" breaker and socket to the fastener, then fashion/attach the TW somehow to the end of the handle of the breaker bar.

Just tighten it with a long handled breaker bar until it feels right. Oughta be able to do it with any wrench over 12" long.

Ah thanks I'd thought about that but I do not have any "feel" I"ll just pick up a dirt cheap length of pipe...I do have a "cheapie" torque wrench that doesn't click it has a pointer that moves to point at the torque - it's more or less my usual breaker bar anyway.

Yeah I've got a 3' pipe w/ breaker bar...now for that d@mn piston nut!!
