So I was looking at replacing my timing chain for a little preventative maintaince and while browsing through Napa's Website I found A Timing Gear set, not a Chain driven gear but a Gear drive Timing Upgrage... ( http://www.napaonline.com/Search/Det...+50014+2014003 )..So what do the people of blazerforum think? Is this a good upgrade from stock or a waste of money? do you think this would cause any problems? Lets hear your input!

 

Never seen them on a V6, always a V8. They sound crazy and I wouldn't mind one, but not sure how quickly it would get old.

V8 "gear drive blazer" search on Youtube

 

Yea, but those are straight cut gears with two idler gears like this ( http://www.google.com/imgres?imgurl=...:0&tx=87&ty=40 )( pete Jackson co. makes noisy and quiet ones but you cant use the ones with ilder gears on vehicles with knock sensors ) theese gerars are a hellicial cut so they should be very quiet, but is their a perfromace gain?

 

we put a timing gear setup on our old ford shop truck at the last place i worked. that was like 3 or 4 years ago, its still in there! lol

i like them, but i would imagine that over time the teeth would wear and cause your timing to go out a little.

 

Yea, but i would imagine that even with wore gears it would still be more accurate then a streched chain? right?

 

Your knock sensor will go nuts with a gear drive. Lots more noise than a chain setup.

Wear is wear. So whether its a worn gear drive or a stretched chain, it will affect timing in much the same manner.

I wouldn't really worry too much about the chain in terms of preventative maintenance. Especially if you have no other reason to pull off the timing cover.

 

well I kinda do, I have a pan gasket and timing cover leaking oil, so I figured while im in there it wouldnt hurt to replace the timing componets. you think the knock sensor will still go nuts even with a matched set of hellicial gears?
