underdive HELP!!!!!! Quick replies appreciated.
I can't get the power steering belt loose. I've tried loosening the bolts with no love the belt is a little looser but no where near close to coming of PLEASE HELP.
The bolt on the back of the pump(the one its supposed to pivot on) is loose. The pump will just not budge. I did notice a screw that might be holding the pump to the engine as well, but the suspension is blocking a decent view.
I have tried using the tension adjuster to *make* the pump come down some, but I'm afraid I'll break the tensioner if I turn it much more.
As said, the belt is a hair looser now, but nowhere near what it needs to be. Anyone else done a RVM underdrive job on a 2003 Max?
The car is in pieces in the garage right now, quick help us much appreciated.

Did you loosen the set screw that keeps the whole assembly from moving back?
Its fairly tough to get to, but you need a 10mm wrench and from the passenger side, from the top of the engine, get to the power steering pump, there is a small 10mm bolt that holds the adjustment assembly from moving. Loosen that, then loosen the lower adjustment bolt.

10mm?
BTW, this is the poor schmuck that tried to help tarpoon out with this nightmare.
I saw a smallish screw on the left side(if yer facing the car from the front) of the pump. Kinda behind the actual PS pump pulley. Is this the little bugger that had me pulling my hair out(well, if I had hair, I would have been yanking on it).
The idler pulley, and EVERYTHING else was a breeze. The pivot bolt on the engine side of the PS pump took about 10 mins with an open end wrench, but not that bad. Some heat shield did do a number on my wrist, but I expect a few battle scars when tangling with a car.
I feel pretty bad for tarpoon, he was really excited to get the pulley on(he wants to be as fast as me, WRX)
I'd love to give this another whirl soon. I really enjoy the Max, torque(low end) is something the WRX is lacking, and its rather nice.
Thanks for any help eh?

I made this write up in the How to do section:
More on UDP
I installed a prototype ASP underdrive and here are some instructions I wrote for the job along with the belt lengths I used on my 2K2. If I had it to do again it would be a piece of cake!
1. If a lift if not available jack car up sufficiently to perform work under car. Use jack stands for safety.
2. Remove front passenger wheel and tire.
3. Remove passenger side plastic splash guard for easy access to pulley.
4. Loosen 12 mm locking bolt on power steering adjuster. Head of bolt is facing toward inner fender well, perpendicular to adjuster bolt and just to the rear of power steering pulley. Access to this bolt is best from under car.
5. Loosen 14 mm power steering pump rotator bolt on engine side of pump. It is accessible behind rear precat with a swivel or series of swivels and long extension from center of vehicle. The oil line to the oil filter is directly in line with this bolt.
6. Turn 12 mm adjuster bolt clockwise, as in tightening, to loosen belt. This bolt faces towards the ground and is located on bottom of adjuster. Use a long extension and swivel for access.
7. Loosen 14 mm ac/alternator tensioner pulley bolt. This bolt is in the center of the pulley and holds the pulley to the tensioner bracket. With bolt loose tensioner pulley is free to slide up and down on bracket within the limits of the 14 mm adjuster hex bolt. Turn 14 mm adjuster bolt counter clockwise to loosen belt and clockwise to tighten.
8. With both tensioners in the loose belt position, remove both belts.
9. Use a pneumatic impact wrench remove 19 mm center bolt holding crank pulley to shaft. Pulley is free to remove.
10. Use motor oil to lubricate ASP underdrive crank pulley seal ring on pulley hub. This insures lubrication to the crank seal when installed. Install pulley by hand locating keyway groove to key. Insure that pulley bottoms out on the crank shaft.
11. Reinstall crank bolt and torque to 140 ft/lbs. Locktite 242 thread sealer is recommended on threads.
12. For ease of belt installation, adjust both belt tensioners to insure plenty of free play to belt. Install Gates belt part number K040292 (or equivalent) on power steering and K060408 on ac/alternator. Insure both belts are properly positioned in grooves in all pulleys.
(I'm guessing on this one, I just tighten it until it felt right to me. Might have to refer to shop manual for belt tightening)
13. Tighten belts until belt has 1/4" movement at center of belt. Do not over tighten. Remember the power steering pump 12 mm bolt turns counter clockwise, as in loosening, to tighten belt.
14. Reinstall splash guard and wheel.
