Greetings!

As I continue the rebuild process on my 2000 XKR, I am to the point of looking over the SC. It seems to spin freely, with no apparent grinding noises from the snout or elsewhere.

Does it make sense to take things apart to replace the snout bearings, and change the coupler (I can still feel the spring working), or simply go with an oil change? The proper tool to remove the pulley is available to me as a rental, but I would need to get access to a press to do the snout bearings, etc.

Following the addage "If it ain't broke..." might be fine, but I would like some opinions.

Thanks in advance.

You don't mention how many miles you have. If you don't have a problem I'd leave it but change oil. Since the SC is on top it's not a big deal in 20k miles or whatever to pull it again if something needs 'fixed'..

 

The car has about 95k on it, and the SC oil was fairly stinky when drained. No brainier on the oil, but was thinking that while the engine will essentially be fresh inside, that pulling the SC apart would also pay for me or a future owner.

Sometimes more harm can occur in taking things apart, rather than just freshening the lubricant.

Thanks for the reply and any other opinions on the subject.

I have 170K miles on my car; about 90K on the SC and it was starting to make some noise. All I did was change the oil and all is well again. I'd just go for the oil change.

 

If the SC is off the car for say the valley hoses; I'd rebuild it. If it's not off, and not having issues, just change the oil. I like to change S/C, Transmission and Differential oil every 30k. It's amazing how long those components will last with that fairly frequent interval!

 

I went ahead and pulled the snout to check the coupler and the rotor pack gears. Sure enough the coupler has a nice crack at one of the holes for the rotor drive. Snout bearings seem nice and smooth so they stay put, and the rotor pack also seems Ok. Oil smells like baby puke, and have some Kenne Bell juice on the way.

However, it seems the only couplers readily available are the aftermarket version. Some of the pro Eaton rebuilders seem to prefer the stock spring loaded ones, but those don't appear to be readily available that I can find.

Has someone had success finding a stock spring coupler? Alternatively, what has been your experience with the aftermarket versions.

Thanks
