did anyone here install udp by themselves..?? i'm just wondering if its an easy install...
thanx

 

I had 2k2_6spd do it for me. He is a fairly accomplished shadetree mechanic and he had a relatively tough time. It is definitely not as easy as an intake.

 

Its easy. Just follow Greg's instructions on how to do it.

I can think of a lot more easier things to do. The places where you have to loosen bolts for the tensioners is the toughest part IMO.

 

Here's good instructions also-

I just 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. This will especially help when it comes to the power steering. 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.

Now wasn't that a piece of cake? Hahahahahah!
