does any one have a decription ,and diagram on how to change the coupler and bearing? the time has come to change it soon,it'* getting noisier by the day! any info would be appreciated.

its not bad...

IIRC the SC does have to come off the car do to this, because of a long stud that goes thru the acc braket....

but for the actuall changing of the coupler is below

Drain the SC oil out of the Nose (perpare for the worst smell you have ever experienced)
crack the Nose drive off with the 8-9 10mm bolts that hold it onto the case
remove the nose of the SC
remove the coupler
install the new coupler
apply red GM gasket maker to the nose cone of the SC, there is a pic around here to show you how to apply it
install the SC back on to the car tightening the bolts that hold the SC to the case
add the GM supercharger oil back in to the Nose of the SC (you will need 2 botttles to complete this)

and your done, after that reinstall the SC onto the vehicle

Only one bottle of oil for an M62. But buy two so you have a spare.

You need a supercharger outlet gasket, two yellow coolant o-rings, red gasket maker, coupler, and oil.

You SHOULD also replace the fuel injector o-rings while you're at it. Torque specs are in Techinfo.

i have also forgotten that the bearings need to be changed in the SC ,is there any other steps for that?,and does anyone know where i can order these individual parts?

Do you have a press? If not, get a rebuilt ND from www.canadiansupercharger.com

If you have a press, get the parts from www.rollingperformance.com or www.texasthunderbirds.com or www.intense-racing.com and DIY.

thanksfor the links,yes i have access to a press,but i am unable to upload the diagrams from the tech info any suggestions?

i would rather change the parts my self because of a tight buget, i have a bearing noise under moderate load and at idle,,,how long wll the bearing last b4 it'* crucial to fix???thanx,,

I haven't finished writing the web page for rebuilding the nosedrive. You can use the info at www.rollingperformance as a general guide, even though it'* for an M90.

I need to stress that if you haven't done bearing work like this in the past, you shouldn't attempt it. If you're rebuilding your nosedrive, DO THE NEEDLE BEARINGS ALSO. You'll have it apart anyway.

To date, I think I'm the only member here that'* rebuilt nosedrives. I'm doing another in the next month or so, so if you can wait that long, I can get more specific for you as I go through mine. Press depths and techniques are the key.

A word to the wise for the M62'* like yours, because of high mileage and faster rotating speeds, do NOT go with the Viton seal. It'* not soft enough to mate with the groove probably worn into your input shaft. You'll have a leaky nosedrive for a couple months until it 'breaks in'.

i plan on attempting this procedure with my uncle ,a lisenced automotive and fork truck mechanic, i would rather buy a rebuilt nose peice but i don't have the funds for a long time, im just worried about how long i can drive the vehicle in this condition for without doing anymore damage???? un fortunitly it'* my daily driver,,the car has 200k but the previos owner did not take care of the vehice at all,that'* why i picked it up for only $700 because it'* tlc car.

How did you diagnose the coupler or the bearings? They both have different symptoms.
