How To: Align Belt Pulleys (Dayco Belt Diagnostic Kit 93874) 

That's some GREEN belt! I've never seen one before. This tool is very interesting. I'd just discovered you having watched your video on fuel pump sending unit adjustments. Very good. Recently a friend and I went nuts trying to figure out why the pulley's were out of alignment on a used car I'd bought. It turned out to be a missing spacer at one of the power steering pump adjustments, and being over tightened where the spacer would go. In addition to that the main mounting of the alternator hole had worn to being an oval. This was caused by someone in the past that had worked on the car. It took a lot of figuring on our part (eight hours) and once we realized something was wrong in the area that the spacer would go, we then rechecked the factory service manual diagram and that confirmed a spacer belonged there. We'd have found that out a lot sooner if the factory diagram had been drawn better. This had to be the most odd problem I'd experienced in all my years of working on cars.

I didnt even know aligning the pulleys can be such a pain! Again great info shared!!

I can't believe I didn't see this video before; really do need this product. I have had a chirping sound come from the engine since first time I fired it up. I had to modify an AC compressor relocation bracket I ordered from Kwik Performance. It involved removing material from one end and adding washers on the other. Thanks Terry!

Doc knows best keep up the great work brother

You’re a hidden gem on RU-vid brother you’re shit is dope as f”@k

I just bought one of these dayco Lasers. Worth every penny

Thanks for another great video!

This is a good video mate. You should do a video about belt alignment where the belt that needs to be aligned is on the inside edge of a pulley with two belts. Like a power steering pump with the belt behind the main belt but both run of the balancer.

Nice pulley kit. Gonna need one of those for my Powerbond soon

Great video, liked and subscribed cause you explained it well 👍 Can you do a video or do you have a video of how to actually move the pullys if they're out of line? My alternator pully is out of line after a mechanic didn't put it in properly Also would you recommend an amature doing it? I've got alot of engineering experience but no car experience, is it difficult and can alot go wrong? Thanks alot for your help and stay safe

You must read my mind. I ate about 5 belts on my ls simple kit. I've even talked to murphy about it. Sometimes the belts stay on. Sometimes it slips to the rear of the crank pulley....going to buy that asap

Great video , my belt on my 2001 firebird has been jumpen off almost everytime I hit a puddle.

Great video I know a few guys that could have used this tool.

i used this for my homebrew supercharged miata build XD.

Hey Terry. I have been chasing a squeak for over a year. It's almost gone but still sneaks back in. What's the actual adjustment procedure? Shimming or pulling pressed on pulley's off and reinstalling at a different depth?

That is a nice gadget to have! I'm wondering if they make one for old school v-belt setups?

What brand is the Green Belt?

Thank You!!!
