SPC has revised the Light Racing UCA's with these new "Spec Ride" Bushings. They are a typical pivot bushing with some differences. It is a one piece bushing and pivot sleeve as opposed to two bushing halves and a metal pivot sleeve. The bushing is to be pressed into the UCA and is meant not to move once seated. The inside of the bushing has a grid surface to it which seems will stop the pivot sleeve from squeaking on the bushing. SPC claims that the "Spec Ride" bushing should never require grease maintenance. I was ready to tap in some zerk fittings until I seen these. I don't have to now!
Heres the How to:
Reciprocating saw with bi-metal blade
Big screw driver
5/16" drill bit
Thick rubber sheets (if you want to protect the UCA paint when in the vice)
1/2"x5" bolt with nut
How to remove the old bushing:
1. Put the UCA on the vice. Protect it with some type of rubber between the vice and UCA if you don't plan on repainting.
2. Drill holes in the rubber portion of the bushing with 5/16" bit. Drill as much as possible to get the reciprocating saw blade between the inner bushing sleeve and outer bushing ring.
3. Insert the reciprocating blade into the hole you just drilled and cut the remaining rubber bushing out. The inner metal sleeve will fall out. Chuck it!
4. Take the recuperating saw and cut the outer bushing ring. BE VERY CAUTIOUS AND TAKE YOUR TIME. YOU CAN EASILY CUT THE UCA BUSHING HOUSING RING. IF you cut too much, you're screwed and will have to weld it for reinforcement.
5. Take the screw driver and the hammer and work the bushing ring out. It should be fairly easy to come out. I few hits around the ring and its out. If its still not budging, you didn't cut through enough of the ring with the saw.
How to Install the new Spec Ride bushings:
1. Put UCA back on the vice.
2. Take some dish soap and lightly coat the inside of the UCA bushing housing and the smaller end of the bushing lip.
3. Take the 1/2" bolt and feed it through the old UCA washer, New Bushing, UCA, a piece of rubber, another old UCA washer and the 1/2" nut. If you don't value the paint on the UCA, don't bother with the rubber. The SPC logo will face out on the bushing.
4. Start tightening down so the bushing goes in on an angle. One of the UCA housings have a vent hole on the inside. Be sure the angle the bushing lip away from the hole so the hole doesn't slice the bushing as its being pressed through. Tighten the bolt assembly until the bushing pushes through. Do not try pressing the bushing in straight as you will tear it.
5. Hammer and the rest of the bushing through. It should only take one or two solid hits.
6. Take the supplied lube and coat the inside of the bushing where the pivot sleeve will go.
7. Push the pivot sleeve in with a couple light taps with the hammer.
Now go and install the new set-up with the supplied washers. Do not use the old washers. Their last job was installing the new Spec Ride Bushings.
While you have everything apart, I would remove the ball joint boot and clean all the old grease out. Load up the ball joint with enough new grease to fill the void of the boot. Then reinstall the boot.
The replacement bushings are now on SPC's site. It seems there are two different UCA's so there are two different part numbers, you may want to check with SPC as to which one to order if you don't know. The part numbers are 25466 and 25476. You can plug them into this web page > SPC They also have the installation instructions listed as well > Install Instructions A lot better than mine.
They also have the replacement boots available as well. That part number is 25477.
The Bushing kit ended up pricing at $25 and the ball joint boots are $6 for the set with NO shipping charge on them! SPC is a great company to deal with.
