pulley install help

oct1285 · 05-08-2010, 10:57 PM

My buddy and I have been trying to install the RE pulley kit for a few hours now. we have both new pullies put in place and one of the belts routed. we are having trouble placing the accesorie belt over the tensioner. NO matter how hard we try we can't get that damn belt over the tensioner. Are we missing something here? Its routeed correctly as far as we can tell.

I had the same problem. I know it looks absolutely impossible to put the belt back on. What you want to do is that route the belt on everything except for the tensioner. Use a long wrench to push down the tensioner until you can't any more. The longer, the easier to hold it at that position. And use another wrench to leverage the belt and push it up toward the tensioner. It's tough. But it's doable. And I didn't even have a second set of hands.

Oct1285 - I put the AA pulley on 4 times now. The first time, the belt was too short. As much as some have been convinced that my first belt length was correct, it cannot be. The 2nd belt sent by AA was just 5mm longer but fits perfectly and was still a PITA to instal but it was possible. Route the belt in to all accessory pullies and the leave the tensioner pulley for last. Pull or push on the belt before the tensioner start to make sure it is not on lip. Here's the key -> If the bolt (in the center) for the tensioner is not below the belt as it lays relaxed, then your belt is too short. THe bolt should be below the belt so you can put your socket in there. Lubricate the belt just at the pulley so it slips over the tensioner pulley. or lubricate the pulley. Push the tensioner to the bottom and hold it while you get two or three fingers around the belt and lift it over the tensioner pulley. Basically if your socket won't go on the bolt because the belt is blocking your path, then your belt is TOO SHORT! If you are able to get your socket in there and the belt is above the socket, you should be able to do it. One more thing. If you still cannot do it, loosen the bolts (2 of them) that hold the tensioner to the engine. Don't remove them, just loosen them and the whole tensioner will have about 1" of play and that play will allow you to put the belt on. Now tighten the bolts on the tensioner body. It will be tight as the whole thing is now under pressure. Try to loosen the bolts as little as possible, and do little by little until you are able to get that belt over. Make sure the 2 bolts are snug and reassemble the car. 12ft-lbs. on the pulley torque bolts.

See, I thought that the belt they gave me was too short too. I'm thinking "there's no way this belt goes on there" But according to the rogue engineering site, I have the right belts according to the part numbers. I'll have to try the prying technique mentioned above, then if that doesn't work loosening those two bolts on the tension arm.

yeah, the wrong belt was supplied. Damn near stripped the bolt on the tensioner to get this wrong belt on there. The wrong belt was in the right packaging

Eliminator · 05-09-2010, 01:09 PM

Oct - if you need to, you can switch the tensioner pulley bolts. put the stripped one on the easier belt.

after 3 trips to various auto parts store, finanlly got a belt that works. it's 10 cm longer than the one supplied and it clears the pullies just fine. After two days of dealing with this, I can't say I feel any difference.

Eliminator · 05-09-2010, 07:20 PM

Agree, you can't really feel any difference. The steering gets a little stiffer. 'ats it. Butt dyno not sensitive enough to pick up the difference in hp... what is it 6 or 8 whp?

they claim 8whp. I do notice the rpms climb quicker, and my steering feels weird now. It could be in my head but it feels lighter now at speed.

I had been considering a pulley for a first or second mod, until reading this. I guess I won't bother. I didn't realize steering would be affected by the underdrive. I thought it was just eliminating the pessimistic over powering of the peripheral systems.

Damn the careless monkeys that shipped you the wrong belt.

the steering was actually in my head, it's the same.

After the pulley install, normal and power mode feel virtually the same.
