Installation

For engine applications, the outer member is usually bolted directly to the fl ywheel; for other applications, to a suitable adaptor. The inner member normally attaches to the driven shaft. The smaller LCD couplings generally have a tapered bore, which accommodates a standard split tapered bushing which grips the drive shaft. (Refer to Table 1 - Split Tapered Bushings). This confi guration provides easy installation.

Figures 15 and 16 on the next page show typical installations involving universal joints.
