4g63 timing belt help

[highrever]

I need some help with this timing belt install. I am a first timer.

To start off I have replaced the balance shaft belt no problem, water pump and new tensioner pulley and idler pulley. So the problem I'm having is when I go to tension the belt through the tensioner pulley, the cams move out of time. So I proceed to remove tension from the belt and line everything up again crank, oil sprocket etc. Then I try putting the exhaust cam off one tooth like vfaq's tells me to do, with everything lined up on the correct timing marks. So, I again proceed to tension the belt with the pulley and great the cam marks line up so I tighten the bolt on the tensioner pulley, then I loosen the tool that pushes on the tensioner arm and when I loosen that the cams go off of their proper alignment.

This is getting very frustrating I'm loosing patience here. What am I doing wrong? I keep re-doing each step over and over and I get the same results everytime. Please help me

Honestly, i didn't wanna follow along with your ONE GIANT paragraph..

I read the part where your having trouble with the cam gear.. Ether

A.) Use zip ties to hold belt onto cam gear
B.) Jay Racing Timing Belt Tools Kit [TBTS] - $50.00 : Jay Racing

These are the only way to do it.

But first, have you applied the correct amount of pressure to the tensioner? Are you able to freely move in and out the grenade pin? If so, proced to having a friend hold the cams in place with two 17mm wrenches as you use the jay racing tool or two zip ties to hold the cams in place.

After wrap the belt carefully around the idler pully, around the oil sprocket, the crank, and finally the tensioner pully. Make sure you have the belt taught we you go around the first three (idler pulley, oil, crank) so all the slack is in the front of the timing system. After, if you bought the jay racing tool set, youll have the necessary tool for tensioning the tensioner pulley. If not, you can use a screwdriver, or a pair of pliers, whatever, tension the pulley and tighten the through bolt.

Make sure everything lines up and rotate the timing belt 2 times around. Loose the tensioning bolt for the auto tensioner and let system sit for 15 minutes. If the grendae pin is still freely movable, you're good to go. If not, redo previous steps.

Obviously if the motor is still in the car, the tools you use will vary.I HIGHLY recommend purchasing the jay racing tool kit. Makes your life a LLOOOOTT easier.

The plastic cam gear lock is worth the price alone.

^ Bastards started making that part no more than six months after I purchased the threaded rod and eccentric tool from them as their previous "kit".

Jay does sell the cam gear locker separately... or at least he did.

EDIT:

Looks like he still does: http://www.jayracing.com/index.php?main_page=product_info&cPath=17_229&products_id=213

hey guys I still need help. I just finished changing my timing belt and while I was spinning the motor six times I sheared off two spark plug wires and when I tried to start the motor it would not start.?

I found out I'm not getting any spark from #2 and #3 coil. I checked the two connections coming from the cams and crank and both are connected. Does anybody know what the problem is? Did I do something wrong, could the shearing off the wires do something or mess something up. Any info would help thanks and I did replace the wires

 

[TurboTsiThatFly]

Explain what you mean by shearing the wires off? doesnt make since to me did you cut them in half?

 

[rhodes2010]

Disclaimer - have not done my Eclipse timing belt....
But when I did another asian car recently I found that I had to disconnect the battery for about 30 minutes after the belt replacement to get the engine
to start.

Of course all procedures demand that the batery is disconnected first, but I often ignore this.

But when I could not get a start I disconnected the battery for a while the tried again.

So. Just my 2 cents.

 

[400hp93talon]

I want to know what you mean by "sheared off wires" please explain!

 

[highrever]

i cut them in half

 

[highrever]

I recently put my timing belt back on and set everything properly so i think, i spun the motor six times and all the timing marks finally align. When I start the car up, it starts and makes a lite ticking noise and shuts down. Also when trying to start the motor its like it gets stuck or grabs while turning the motor.

I also installed a front mount intercooler. So is this a timing issue or is this caused by the front mount cooler or Is this something else?

 

[SpoollinAwd]

I would make sure your in time do you have a timing light or anything?

 

[highrever]

I was wondering if that little metal plate on my crank shaft has anything to do with the sparking of the coils. Mine has a little chip gone out of it in the square grove that slides over the crank square dowel and was wondering if that little plate moved would it cause no spark from 2,3 coil pack because I'm getting spark on 1,4 and yes I tried a different coil and no luck. or maybe there's something else that could be why this coil isn't firing. please help I'm going nuts here

 

[monster4g63tawd]

if your sparking on 1 and 4 i dont think it would have anything to do with the trigger plate. if you already tried a new coil then it could be your wires test for spark at the end of the wire and if your good there pull your plugs and check them out and check the gap

 

[GRAVEDIGGER]

A lot of good information here that might help explain things. Good luck

I would double check the timing belt alignment marks. I have misadjusted the tensioner and had the belt jump a tooth after startup. She would start run like crap for 10-15 seconds and stall. Check out vfaq.com if you haven't already.

 

[hermangoodgame]

the same thing happen to me and i kept pushing it and then the timing jumped a tooth and scraped my motor it is easier to redo your timing than replace motor good luck!!!

 

[Lou98GSX]

recheck timing marks and make sure that the cam dowels are facing up.

 

[nek]

Is the timing the only thing you did? Correct me if Im wrong but one of your rockers might have fallen off

(its not your fmic unless you didnt put on your hard piping or you forgot to plug in your maf)

 

[Lou98GSX]

another thing to look at is that the notches on the outside of the cam sprockets should line up to the top of the cylinder head surface and the 2 center ones should be perfectly straight with each other because one tooth off will make car stall.

Also look at the timing mark blowup in figure 4 here: Timing Belt VFAQ

 

[hoby0316]

Check timing belt and then check timing while running with a light.
