Hey there,

I have a 94 SSEi that makes noise at both idle and while driving. At idle it'* sorta clunky and when the RPM'* drop it makes a definate clunking noise. When driving it sounds more like a metal on metal....like a bucket of bolts shaking or something. I have a new coupler and want to get the bearings put in. I figure bearings are cheap and getting a shop to press them isn't expensieve either. Am I correct in thinking I need both the coupler and bearings. Also, is there any way to tell now that I have the SC apart that the bearings are bad? I have 3 part numbers from this site for bearings/seals.

1-6204.C3(brng)
1-6203.C3(brng)
1-7965CR (Seal)

Can any describe which bearings go where so I can tell the shop exactly what to do?

Thanks

The bearing number will etched into your old bearings inner race, just wipe away the grime to reveal the numbers.
If you turn the bearing slowly in your hand, you will feel a soft (flat) spot or some tight (restrictive) area.
WHile the rotors were mounted you could have checked the bearing for any side to side or up and down movement. There shouldnt be any end play either (in and out).

It wont take a shop long to change out the bearings and shouldnt cost too much.

I want to verify what I'm looking at when I opened the SC. By the way, it'* a 94. The SC came apart in 3 main pieces, the snout, the middle plate which has the rotors and gears on it, and the rest of the SC body. Which are the bearings that get replaced? The ones in the middle section in the plate between the rotor and gears or in the main SC body? With the pieces apart, I can feel a little wiggle when I pull the rotors away from each other.

Thanks again. I want to do this car right. It'* my brother in laws. He wants to sell it and if I fix it right he'll give me half.(the dealer told him it'd be $2k to fix it) It'* a 94 with 150k on it...and I"m thinking of buying it for a 3rd car to play with a little. Although, I definately see an oil leak somewhere under there!

any movement at all will cause the rotors to lash. I have never rebuilt a sc but have changed out many bearings and have worked on many roots style blowers (air compressors at work).
You would want to replace all the bearings if you took the time to take it apart. Bearings are cheap labour is pricey

Today I was able to get the new bearings into my SC. A friend of a friend works in a diesel repair shop in town and we did it on his lunch hour. It wasn't too bad once you have the right tools. Now I have to clean the carbon off of the rotors and casing (I'm doing it by hand and it'* taking forever b/c I don't want to get the cleaners in the bearings) , reassemble it, and put it back in the car...I'm starting to see the end...or wait, the beginning!
