CAUTION / NOTICE / HINT
Note
When using a vise, place aluminum plates between the part and vise.
When using a vise, do not overtighten it.
PROCEDURE
INSTALL SPIDER BEARING
Tech Tips
Use the same procedure for both spiders.
Apply grease to a new spider and new spider bearings.
| Grease |
|---|
| Lithium base chassis grease NLGI No. 2 |
Note
Do not apply too much grease.
Install the spider to the flange yoke.
| *a | Turn |
| *b | Hold |
Using SST, install 2 of the spider bearings to the spider.
Tech Tips
Before installing SST, sufficiently raise the part labeled A. If the part labeled A is too low, it may be difficult to install SST.
Using SST, adjust both spider bearings so that the snap ring grooves are as wide as possible and equal in width.
Install 2 new snap rings to the installed spider bearings. The snap rings must have equal thickness and allow 0 to 0.05 mm (0 to 0.00196 in.) of axial play.
Note
While the installed snap rings should have equal thickness, if the axial play is greater than 0.05 mm (0.00196 in.), select 2 snap rings that have as close to the same thickness as possible.
Tech Tips
Do not reuse the snap rings.

Install the spider bearing on the sleeve side using the procedure described above.
Align the matchmarks on the flange yoke and propeller shaft.
