[FONT=Helvetica Neue, Helvetica, Arial]Hi,
I have a 1992 Glastron with a Volvo duo-prop. Its a 431B 868629 (?what that 868# means). V6 4BBL. S/N 41001365XXX. I think it's a DP-C unit. I've owned since 2007 and am the second, freshwater only owner. The silver plate on the top of the upper unit has lost any of its ID #'s. The plastic cover over the carb. has lost most of the ID numbers as well. At one point, I have written DP-C in a book I have, so I'm thinking that was visable at one point.
So, my upper drive bellows ripped and I need to replace the u joints as both rusted a bit. I think it broke over the winter (upstate ny) and snow got in there. I swear it wasn't ripped when I cleaned the stern last Fall; who knows.
So, I wen ahead and removed the drive gear from the upper unit by removing the 4 hex bolts. I carefully noted the order and positioning of the 3 shims. The o-ring needs to be replaced on both the drive shaft and the gear housing, but otherwise the bearing assy,drive gear and movements all seem very good. I did remove the 7/16" bolt and cone washer to get the shaft out for u-joint replacements. Do I been to pre-load prior to re-assy? what are the torque specs for the hex bolts and the 7/16 bolt? Or, am I completely wrong?
Thank you!
Tom
