Underdrive Pullies

[madstyle1]

im about to install steeda underdrive pullies just wondering if i have to buy a new belt.... got a 2004 GT with 4000 miles on it... should still be good right??

 

[dsg_gt2004]

im sure it is...i never heard anything about a new belt..so my answer is use the stocker unless it looks cracked or worn WHICH i highly it will

 

[myponyrocks]

I have the Steeda UD's and it uses the stock belt. The stocker is still in great shape (30k+ miles)

No need for a new belt, i had 13k on mine when i did mine and there was NO sign of wear, let alone a crack or problem. The old belt will fit perfectly with the new pulleys.

Any need to apply silicone to the crank pulley when installing the Steeda's?
I heard others having to do this to avoid an oil leak and wasn't sure if this is needed with the Steeda Pullies.

I have never heard of having to use silicone to seal an oil leak on a pulley. That doesn't make sense, there's no oil running through a pulley. I did pulleys on mine and the factory belt fit fine. But it started squealing some after (it had around 94,000 miles on it at the time) so I went ahead and replaced it with another factory size belt a couple weeks later.

No, it is not needed.There is a small amount that comes out when you change pullies,but no leaks.Also, as stated before, it uses the stock belt.A pretty straightforward install.

BULL! The Steeda instructions state that you should put a bead of RTV (It may have been silicone) in the keyway BEFORE installing, this IS to prevent a leak or something... not sure BUT YOU HAVE TO DO THIS

ummm....have to?I have been running mine for over a year and no leaks.It may be a good precautionary measure.

Sorry, but I agree with GTvert01, I have never heard of having to use silicon to seal anything up. Instructions say a LOT of things, but a lot of them aren't necessary.

Apply a dab of high temperature silicone sealer (gasket maker) to the keyway slot on the underdrive crankshaft balancer pulley. Line up the keyway and install the pulley. Use the longer bolt supplied to pull the balancer onto the crankshaft. DON'T TIGHTEN THE BOLT ALL THE WAY. ONCE THE PULLEY IS MOSTLY ON, REMOVE THE LONGER BOLT AND INSTALL THE FACTORY BOLT. Torque factory crankshaft bolt to factory specifications.

Ok that doesnt say why... still searching

When installing the Steeda crank pulley, notice that they include a longer bolt to help get the pulley started on the shaft. Before you put the new pulley on, put a dab of silicone on the crank keyway and some oil on the pulley oil seal area. The silicone prevents any oil leaking out through the keyway and the oil will ensure you don't damage the seal when tightening the pulley down. Make sure you remove the longer bolt before the last portion of cinching down the pulley and replace it with your new, normal length bolt.

For some reason URL gets edited, I dont think its a badd word?

Ok its listing oil as the only reason. Sorry I was an ass, was in a bad mood earlier. Any way, its always better to be safe than sorry, especially when safe only costs 4 bucks or so at most, assuming you dont have access to any for free. People shouldnt discourage something that may do nothing, but has been reported to stop something bad from happening.

True that.

 

[GTvert01]

agreed

the steeda instructions state to use a small amount of silicon or rtv on the keyway slot. Why not just do it if youre going to install them it could possibly save you time and headaches in the future. The mechanic who put mine in almost forgot but I reminded him, no leaks that I know of. BTW hope you have good air tools and get a loaner pulley puller from the auto part store.

 

[myponyrocks]

OOOH good point, the autoshop I went to had to rig something cause the steeda bolt is different than any puller he had when he was reinstalling
