Hi, i have a question regarding torque. I'm trying to change my water pump and I have to take off my crank pully bolt and retorque it to 181 ft/lbs. I don't have a torque wrench that goes up that high, but I do have one that goes up to 150 ft/lbs.
I went to my local kragen auto shop and some guy told me that I could torque my bolt by setting the torque wrench that I have to 100 ft/lbs and then torque it, when it clicks torque it again at 81/ft lbs to have the added torque to 181 ft/lbs. I wanted to know if this is an accepteable procedure in torquing the bolt. Has anyone ever heard or done this being done? Please reply thanks in advance.

 

to me that doesn't seem like it'd work. once you got to 100, i don't see how it wouldn't know you were there, i don't think you'd be ablet to do that.

 

"once you got to 100, i don't see how it wouldn't know you were there"

I don't understand what you're saying here...I would set the torque wrench to 100 lbs...i would here a click....then i would change the torque wrench to 81 lbs and then torque the bolt again...totaling the overall torque to 181 ft/lbs

 

but the second time you are only tqing it to 81. if you tq it to 100 the first time and then turn the handle to 81 you will hear it click at 81 and the bolt or what ever wouldnt even move because you have already tqed it to 100 ftlbs

 

icic...thanks for the reply...that makes sense...thanks....that guy at kragen is a freakin idiot

 

lets hope he was just pulling your leg.

Once you set torque wrench to 100 ft/LB, thats it, setting it to a lower setting afterwards will not turn the nut anymore (your under the 100 ft/LB you just did).

LPED

 

in regards to this problem...i now need to know where i can get a torque wrench that can torque up to 181 lbs. where can i buy or rent one that is inexpensive.....i've seen one around for like 100 bucks... but that throws off my cost/savings alot for doing the labor myself in changing my timing belt and water pump....

Also...someone told me to just mark the pulley and the pulley bolt and then just try to tighten it to that mark....i mean is it that important to torque the bolt to exactly 181 ft/lbs?

well lets see what could happen if you dont.....lose your ac...so now youre getting how and all of a sudden your power steering goes out and you lights begin to dim...wtf you say and next thing you know the car is no longer running because your pistons slammed into your valves because your cams were no longer turning

 

ic....do you know where i can get a torque wrench that can torque up to 181 ft/lbs for cheap?

well i found one on amazon for pretty cheap...but i'm not too sure about this brand...anyone ever here of "mountain"

One way to get more torque out of your 150 wrench is to make the wrench longer by adding an extension to the drive side (not the handle side) of the wrench.

You calculate your new torque setting using a formula... see http://www.norbar.com/torquewr...r.php

I have no idea where to get the extesion... most common example is a crawfoot extension but that wouldn't work for a pulley bolt...

HAHA, LOL!!! thats funny, I do hope he was just joking.

My torque wrench only goes up to 80 lbs/ft so whenever I do something that requires more than that, which isn't often, I just go to AutoZone and rent their 200 or 250 lbs/ft (or whatever it is) torque wrench. Cost ~$100 up front but you get that back when you return it and I think you have like 90 days to return it before it becomes non-refundable.

 

Serousily man, just hit it with big impact for a couple seconds and you will be fine. Or the biggest breaker bar with you have and a cheater bar on it.

Because of the way honda's turn, the crank pulley bolt tightens up over time. Hence why it takes all my might and 4-6 feet of leverage to break loose a bolt.

I have done a million hondas and not torqued the crank pulley down properly and in hundreds of thousands of miles, not one has come loose.

Good luck

 

any cheap impact gun should do about that much torque

 

Rent one as TourningAccord mentioned. It's better than buying one that you'll only use once or twice.

lolololol lololololol lololol
Man this post just made my week maybe even my year.

hondatech94, you have to go back to that store and have that guy demonstrate this procedure for you. Make sure you record video of him explaining and demonstrating it. Then post it up. I want to see the look on his face when he realizes that he's an idiot....

 

yea i know....this has got to be the single worst advice given to me....on top of it he works at kragen auto parts....i would asumme he should have some knowledge in this subject....im a little dissapointed....i kinda forgot his face but maybe i'll go back and ask him about what he said....that guy is a freakin idiot.... thanks for the reply guys.

 

yeah, just because they work at an auto parts store doesn't always mean they know what they are talking about. Dont get me wrong, some do but some are just there because that was the only place that called them back for an interview. It's always good to have some knowledge on the subject before going to a parts store, it can really save you some time/money/frustration.

 

That's funny enough to quote in my sig...

 

hahahahh.... I think everyone should....i'm just shocked

 

Hmm.. Yet another prime example of leaving it to the pros..

And you wonder why there's a difference between technicians and mechanics.. Guys like him give technicians and mechanics a bad rep..

But I do admit, I sure wish you'd try it out and tell us how long the bolt stays on there. That would be quite interesting, sorta like MythBusters..
