If you apply 40 lb ft to the end of a wrench haven't you multiplied to torque at the bolt?

You didn't go to school did you now cuz the lenght of that wrench will change the torque value on the pulley bolt.

Looking at the multiplied leverage, would be around double the torque applied to the bolt! Ha!

Your losing torque with that setup, so your likely more at 34-36lbs.

@22muhammed22

with a longer arm and the same force, you have more torque. it is almost twice the length, so it will be around 70-75lbs

If you check, the blower is American made and i believe the pulley/clutch assembly bolt is SAE 15/16th". Also, replacing assembly could be difficult but can be aided by using graphite dry powder (lock lubricant) applied to the bearing seat or inner bearing race.

German engineers would suck their teeth seeing you use non metric tools. LOL

ALL of the information I've found never mentions a metric size even, which shocked me. There is 0.2mm difference in 15/16" and 24mm so it is safe to do. However, because of bolt and nut availability, I figured it would be safer to use SAE for this particular task. Perhaps if I found German documentation I could have found it was 24mm, I had to figure that out on my own to mention it!

Mr. KZread Expert doesn't know when annotations were remove from videos, information got removed from videos that weren't embedded in the video.

The torque wrench should have been held at a 90 degree angle to the combo wrench so that the torque setting would have been accurate. Held straight the torque applied is way off.

No need for such extension to torque the nut, a direct torque wrench works fine. Please stay in metric units. Anyone willing to work on that car should get a metric tools set.

The torque wrench doesn't work when it won't fit between the bolt and fan shroud. I didn't do it because it looked fun. Most people who routinely work on cars have SAE and metric, not everybody does and use what they have.

What is the right torque to tight up the pulley?

Great video!!Thank you for that!!! I tried the 24mm spanner and is slightly loose so I think you better use the 15/16 spanner and 15/16 socket for the wrench as the 24 mm is slightly bigger. I bought all the materials except I cannot find that special bolt which you use to connect the spanner with the wrench.Do you have any links from where I can buy it??

@EMFAudio

It isn't a special bolt, it's a bolt with a nut on it.

The 40 ftlbs is calibrated by the length of the torque wrench by adding length it changes .the torque wrench ur using is about 2ft length uv added about a ft. Correct me if im wrong.

Jasmeet Oberoi annotations have addressed that, a 90 degree angle must be used for accurate torque. It was hard to position and film.

What am I missing here? Why can't you just put a 15/16" socket and torque wrench directly to the pulley bolt?

IIRC, the 84mm pulley and cooling upgrades, and tune that are needed for that are good for around 50 HP. Mid length headers which I also have on there now are another 25ish.

Do you have any other performance upgrades other then this pulley and tuning? Have you noticed the car more powerful at part throttle?

What size pulley did you have on it before? And is that the factory size belt or smaller one!

@EMFAudio

5 жыл бұрын

It was the factory pulley, I'm not sure what size it is. You can use the same belt length, if you did a 77mm pulley you'd need a shorter one I think. I say the same belt length because I have a belt wrap kit also which needs a longer belt, but I didn't change the belt length as a result of the pulley ( I think, I did this a while ago, I don't recall having to get a new one).

Using the smaller 84mm pulley does it require reprogramming the computer?

The pulley itself? I'd remember if I heard it but I can't recall, that was several years ago.

This Is about the riskiest way of doing it. You’re risking to break off the aluminum cast on the Kompressor where the clamps push against. Too many have ruined a $5500 Kompressor that KZread mechanic way. Your Pulley is made from aluminum and comes from Shardul Meta from Texas. He just sells them to Eurocharged and they mark them up and claim it’s “theirs”. The rivers are junk and eventually will come lose and will shred your engine cover. Last but not least your belt wrap kit is junk too. On a positive side: you speak clear, don’t cuss and dint speak 800 words a minute.

@EMFAudio

If the supercharger broke, the clamps were too tight. I've never heard of anyone breaking those. As far as being junk and breaking and causing problems, I daily drove the belt wrap kit and pulley for 3 years without a single issue. Flawless service from the time of this video till a month ago when I sold the car, probably still fine now. Just because you paid 3x more for someone else's doesn't mean it's better or the cheaper are bad.
