timing belt

[integralover]

can anyone tell me the steps to take to replace the timing belt? i lost my bible(haynes) and cannot find it.

your better off investing in another haynes or helms if you've never done it before. two thumbs up for the haynes with my first water pump and timing belt install.

If you need it soon then I will try to scan mine and send you the links to the pics.
Also there is a thread in here that someone linked to a site that you can download the manuals from.


EDIT: Here is the link.

now that i have changed out the timing belt. and it is on nice and tight. now i have a huming noise. is that b/c the belt is new. that happended with my alt belt and that went away. i did not do the water pump. i guess that will have to be done later this week. so my question is about the humming noise. is that normal for a new belt. i have one of those gatorback belts.

???? I have only used OEM belts so I don't know about the noise being normal or not.

if it's hummming then u tensioned the belt too much. u better not keep the tension too tight or else.... snap, there goes ur timing belt and valves and pistons and if ur lucky, ur sleeves too

going to loosen it tonight. the bad thing was since my car is in the garage undrivable my dad let me use his 96 911 turbo to go to work today and is there an easy way to adjust the tensioner with the timing belt still on?

i dont really do much work on my own car... dont have a ton of tools really plus i dont really want to "learn" on my car even tho i know i am perfectly able... but i take it to a very experienced mechanic to get worked on and he changed my timing belt and there was a humming noise too he said it is normal to hum a little at first and it will go away. somethin about wear on the pulleys and some harmonizing crap i didnt really care tho so i didnt really listen.

easy way to tension belt:
well if u put back on the upper Plastic timing belt cover, u will have to remove it. i think it's held on by two 12 mm bolts. once thats removed, loosen the timing belt tensioner bolt (if u look directly by the tensioner pulley, u will see/ feel a rubber plug on the lower timing belt cover. remove this in order to gain access to the tensioner pulley bolt. i think it's a 14mm) look inside by the timing belt tensioner pulley ( u should be able to see inside there now since u removed the upper timing belt cover) and u will see that a spring and a bracket holding this spring is attached to it (i think the bracket is on the tensioner pulley itself. the spring is attached to two places, one on the tensioner pulley and one on the engine itself).take ur long screw driver and pry up on the bracket (the one on the pulley, not the one on the engine) that is holding this spring. you might need a friend to help u out with this (one to pry up on this bracket and one to tighten down the tensioner pulley bolt) pry up on this bracket and feel the tension on the belt. the more u pry on it the more tension the belt will have. if u have too much tension, just hold less pressure on the flathead screw driver. once the belt has a decent tension (enought that when u push on it from the exhaust side of the belt) it deflects a little bit. not too much and not too tight; about 1/2" deflection. now keep the screw driver in that position and tighten up the tensioner pulley bolt

it may sound confsuing but when u look at it it's very simple

i know exactly what your talking about. just not sure how tight. i have it soooo tight that it does not bounce at all. and the water pump side is even harder. did nto get to it tonight since my dad is letting me use his porsche but will do it tomorrow. thnx for the advice

Do not do what he told you to do!!!!!!
That is the wrong way to do it!
This is what you need to do:

1.) You may or may not need to do this, but take the valve cover off.
2.) Set the #1 piston at TDC (top dead center)
3.) loosen the tensioner bolt 1/2 of a turn.
4.) Rotate the crankshft counterclockwise 3 teeth on the camshaft pulley.
5.) tighten the tensioner bolt. TQ for the bolt is 40lb-ft. It would be a good idea to retorque the crankshaft bolt to while you are at it. 130lb-ft fo it.


This is the only way this should be done period!
The tensioner is spring loaded to apply the proper amount of pressure to the belt. Doing it the way he told you to do it will only bring up the possiblity of damaging something.

whoa:22yikes:damn good thing i checked this right before i am going to do it. something told me to check this. hmm, karma maybe? i will do it your way whtteg. and i am glad i have a torque bar. thnx.

[integralover]

well just finished. yea i took my time on this. no more whinning sound. so thnx again whtteg for the help. and is the belt suppposed to vibrate alittle? mine does. its not as tight as i had it, which was too tight. but there is alitlle bit of give not too much though.

[boosted k20]

not to be a dick whtteg but have u EVER tried it the way i told integralover to do it? i've done this to MANY engines and all have had proper tension and NOOOOO problems. there are many ways to do things, not only one method.
i was assuming that he knows to set his motor at TDC and make sure the cam gears r lined up 1st before he did it my way (he would have to of had his timing lined up since he put everthing back together and started up the motor...only problem was he put too much tension on the belt.)

as long as u feel the tension in the belt while doing it the way i mentioned to make sure that it is not too tight or too loose, this method works fine. Ur method works too and alot of people use it. i just didnt like the fact that u knocked my method of doing it. if u havent tried it then dont judge it!

oh and integralover, the belt is supposed to vibrate when u hit the throttle, but not ALOT of vibration. just a little bit

thnx boosted for your help too.
