An aquaintence has an old Catalina-30 with a Universal 5411. How does one jack the coupler from the prop shaft on this beast. A description of the coupler is a totally enclosed steel
coupler with a rubber disc in the center with 4 radial screws/lugs that transmit the torque into the internal rubber disc (?). There are two set screws on the hub. I assume the coupler is set with a straight shaft with a woodruff or square keyway - no shaft nut in the counter bore of the coupler.
**** I am trying to SAVE the bronze
shaft ***** .
How does one get this coupler off the shaft. Have attempted to jack the shaft by placing a heavy walled socket between the separated coupler and a drilled blank flange (the transmission
attachment 'fingers' are probably too 'light' to bear any 'jacking' without breaking them). Cant heat the coupler hub as I dont want to destroy the internal rubber disc.
Question .... do the radial 'hex-heads' have to come out of the coupler before removal
... these suckers are buried down in the rubber disc and its damn difficult to get any 'bite' with a socket?
Any ideas from *actual experience* on separating this 'wierd' coupler from a Universal 5411 would be greatfully appreciated. I know how to 'jack a shaft' but this one has me stumped. The Catalina 30
is an early 80s mode.
Any *experienced* answer greatfully appreciated.
