5: Release Collar and Cone Separated

Figure 5: Release collar and its cone shown separated from main clutch parts.

The main clutch components are now separated and can be cleaned and reassembled, noting that the retaining screw shown in Figure 2 needn’t be disturbed.

Cleaning of the keyed drive shaft as shown in Figure 6 (being careful not to lose the Woodruff key) can now take place.  Cleaning of the hole through the release collar clutch portion and its keyway should allow the release collar to slide easily along the drive shaft.  Penetrating oil on a rag is sufficient to clean such surfaces.  I didn’t bother cleaning anything but loose rust from the mating cone surfaces and assumed that the engagement of the cone surfaces during normal drive operation would adequately bed-in the parts.
