SUBJECT: REMOVING AND INSTALLING FRONT WHEEL HUBS ISSUE: 08/86-868 NEW PROCEDURE
APPLICATION: SAAB 9000, M86-
As a running change, Loctite 609 is now applied to the splines of the front wheel hubs on the Saab 9000. This is valid from VIN Serial No. G1021278-.
As a result of the use of Loctite, it is now necessary to use a puller when removing front wheel hubs.
Effective immediately, all Saab 9000's should be treated with Loctite 609 whenever the hub is removed and refitted or when installing a new hub.
Supplies Required:
Loctite 609 P/N 02-06-037
Loctite Primer "T" P/N 02-06-045
The required Loctite and Primer T is available from Saab or may be purchased from your local jobber.
Removal/Refitting Directions:
1. After removing the necessary hardware (See Service Manual), fit Puller P/N 87-91-287 and Puller Legs P/N 87-91-303 (150 mm long) to the hub to aid in removal.
2. Before fitting a new hub or refitting the old hub the splines must be thoroughly cleaned with Locquic Primer "T" (P/N 02-06-045).
3. Apply a few drops of Loctite 609 to the splines and fit the hub. Apply Loctite 242 to the threads for the nut and install the nut. Tighten to 198-210 ft.lbs. (270 - 290 N-m).
4. The Loctite must be allowed to set up for one hour and the car should not be driven during this time.
Important Note: This procedure is also valid for cars affected by Service Campaign 514 (See S.I. 03/86-829). This means that in addition to the Loctite 242 being applied to the nut, Loctite 609 must be applied to the splines of the hub as well if the hubs were removed.
