Hi all,

As the thread title suggests this weekend (saterday), I'm changing the timing belt on my 1997 S1 RS-Four stagea. I have had a litle bit of experience with car mechanics but mainly mountainbike mechanics and motorcrossers....

In preperation for the belt replacement I have purchased the following:

  • Dayco Timing Belt kit (Including: Timing belt, 3 seals and Idler and tension Pulleys)
  • A Inductive timing light from SuperCheap
  • A harmonic balancer puller from SuperCheap(SC)
  • Coolant as I will probably be removing the radiator from SC
  • Transmax Z incase I need to remove oil cooler from SC
  • A 27mm Socket to remove the harmonic balancer

I will be using the following guides to help me along the way :

Just a couple of quick questions:

  • Without a rattle gun in an Auto will I be able to remove the harmonic balancer bolt?
  • Checked timing today and it seems to read between 25/30 degrees advance (shouldnt It be 15!!)?

Also if you could leave me any tips or tricks that would be awesome.

Cheers,

Chris

i did the timing belt on my girlfriends stag on the weekend, had it done and dusted in about 2 hours.

few tips, when you take the radiator out, as the remove the transmission fluid hoses from the bottom, you can quickly plug them up with 2 bolts (something about 8-10mm thick should be fine) so you dont lose any fluid.. although, if your fluid hasn't been done in a while, it might be a good idea to drain that first.

taking off the harmonic balancer without a rattle gun is possible... there are 2 ways i've used.

first method is using a breaker bar, and a gimpy.. you can give it a few sharp hits and hopefully crack the bolt,

or the second way is by using a length of rope (about a metre is all you need), you put the double loop over the balancer, and then tie the bare ends up to something such as the water pump, you need to make sure you have the rope around the balancer the right way though, you want it so as you try turn the bolt anti-clockwise, the rope will pull back on itself to the point where the bolt comes loose.

here's a pic of how the rope should be looped, as i had no idea how to explain in! :D

when fitting the belt, it's best if you have someone helping you.

remove the old belt, and the idler/tensioner pulley, then put in the new idler and tensioner, then line up the 2 top marks on the new belt with the cam gear marks, at this point only have the belt about 2-3mm on, and get the other person to hold the belt on the gears, and the tensioner AWAY from the belt.

go under the car and slide the belt onto the crank gear (makes it easier to see the markings from under the car, then come back up, and then slide the belt fully on, and release the tensioner onto the belt.. and voila, you basically just have to put everything back on after that. :D

[*]Checked timing today and it seems to read between 25/30 degrees advance (shouldnt It be 15!!)?

Amongst that first thread you mentioned (SK's excellent guide to exhaust cam pulley change) SK says:

2. There is a lot of parralax error on the timing marks, the marker on the cambelt cover is a long way up and back from the marking on the crankshaft pulley. Take a look at the workshop manual drawing in my early post and you can see the potential for parralax error.

3. Because of #2 above, you have to have the timing light and your eyes aligned and over to the right (looking at the engine). If you look straight down from the centre of the radiator, you get a 5 degree error (ie; 15 degrees looks like 20 degrees). So I had to remove the airfliter snorkel to get my eyes over far enough to eliminate the parralax error.

Maybe that might help explain a difference?

re the timing it will be your timing light for sure. some cheaper ones show 2x actual timing, including the one I tried the other day from super cheap.

But in any case you don't really need to redo the base timing unless you move the CAS on its bracket.

otherwise everything is pretty straightforward.

are you changing the water pump at the same time?

On saterday I did the timing belt and put the new from pads in my Stag....

This was the first work Ive ever really done on a car. Ive never done an Oil change/oil filter but ive done a timing belt and brake pads :wub:

It was rather easy as I had done more than enough research and had asked a number of questions.

Some tips for others:

  • My loop for the timing light at the back of the enigne was reading double timing, so I just took of the cover to the plugs and put the light onto number 1's coil pack and managed to get a descent signal :D
  • I also put some bike tube on the harmonic balancer to aid the rope in getting tension to help unto that massive 27mm bolt
  • I also had a torque wrench from work (bike shop) that proved to be very handy and a rather large pole for more leverage

Im very glad I didnt pay someone to do this as i enjoyed the proccess and learnt alot along the way. Must thank; Stinky Rooster, SK, Rob (Who-on SAU), grigor and mitchy.

I didnt replace the waterpump as it was spining nice and making no excess noise. BUT I DID replace the idler and tensioner pulley.

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
