Hi Peeps,

Ive changed alot of Cambelts in my time, but while Ive had my R32 for over 10 years Id never changed the belt as its done less than 20,000km in that 10 years!. Obviously It needed to be done (I was thinking it would be as hard a nails...) and I didnt want it failing on a trip to Townsville, so I looked up a few "how to guides" in the forums to see if theer are any traps for the RB, and used this StageA guide.

http://www.sau.com.au/forums/topic/73824-adj-camshaft-pulley-new-cam-belt/

which alerted me to the relevant timing marks.

What I noticed in all the guides I found on SAU is that they all remove the old belt completely before putting the new one on, which makes it alot harder than it need be, and introduces another potential timing mistake.

The trick is to cut the old belt in Half along its length.

First prise the old belt half off, and slice it along nits length. Once you start it it will tear along the "nylon belts" that give it strength.

Then Push it right ot the back of the cam pulleys

Put the new belt on next to it.

Then cut the remainder of the old belt and remove it.

And push the new belt into position

I didnt change my waterpump, but its normally easy enough to do that "behind the half belt" when you are at the beginning of the process.

Finally I changed the Idler/tensioner by cable tying the middle of the belt together so it didnt jump teeth while I undid and replaced the old ones.

Hope this little trick is useful for someone.

Cheers

Brett

Thanks to the OH&S rep for pointing me out as "half a job" Harry,

He also forgot to mention I didnt document the date and time of the last change, I didnt change the water pump (something I may actually regret!) and I was running a risk of a broken belt for being negligent for a long period,

So for the 2 or 3 readers who are not perfect I apologise. Seals that harden do leak, and when it happens fix them immediately, else the oil leak will "f" up the belt quickly and have the nasty consequence of dropping oil on your mate's driveways.

I agree if I had a 11.79 second car that gets a proper throttle application on occassion the seals will suffer and need to be fixed on every belt. But for the rest of us with 130HP driven at about 30 HP most of the time the seals do not need replacing very often.

But i cede to to your experience as I do not have such an awesome drag machine in my garage.

An interesting approach, one that I would never have thought of, congrats to you for thinking outside the square.

I don't touch the seals unless they show signs of weeping.

Have seen too many replacement seals weep due to difficulty linishing old wear marks from the sealing surface whilst in-situ.

Saw the zip tie method used during el-cheapo cylinder head removal. My luck would have something drop down there and ruin the show.

Relax mate. It's a good idea, just pointing out that if you're performing a major 100km service, then do everything.

The previous owner of the car I just bought took shortcuts, and now I'm having to redo everything. Though if you've done all that, then what you've posted is a great tip.

Well, pulling off the balancer on an rb26 is a pain, and the torque requires to do them up is huge. It's not something that I would want to do more than required.

It's a nifty idea nevertheless.

:-) My response was a little "sharper" than intended,so a heart felt beer will be offered at first opportunity.

And yes.. I will be kinda cranky if they leak now.... ;-), but in the interests of full disclosure Ill let you all know!

    • Thanks for the linkie. Certainly always a great deal of help when people post comparisons like these, but I think for now I'll stay away from any semi slicks. I did go ahead and order the sportcontact 7. My buddy has them on his modified A4 and he keeps saying how good they are. For my intended purposes these will probably work real well. I'll report on them once I had the chance to try them out
    • Talk about noisy. Even when I still had the Tomei under the car I could distinctly hear the tires rolling. And I doubt I ever will need maximum grip like on a track. My GTR will maybe never even see the 600hp mark and I need to get used to the car quite a bit before challenging the limits of its handling. For the next winter storage I think I will get a set of these rubber drive-on thingies that have a tire shaped base. Those supposedly really help prevent flat spots.
    • Well our climate is definitely way less hot overall and the weather can be quite picky at times. I just know that during normal road use or even spirited drives there is no way I'd be able to consistently stay in the operating temperature, and constantly changing the tire pressure would also be a royal pain.
    • Input shaft bearing. They all do it. There is always rollover noise in Nissan boxes - particularly the big box. Don't worry about it unless it gets really growly.
    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
