7) While placing a steel rod or similar tool through the 7mm diameter hole at
the lower part of the spline, loosen the U-nut at the top of the spline with
the wrench, and remove the bearing and bearing mount plate.
(See Fig. 5-29.)
Use a round steel rod with a diameter slightly smaller than 7mm. Avoid
using a square rod because the spline might be damaged by the edge of the
rod.
At this point, be careful to keep the spline shaft from coming off the spline
nut.
