I recently changed the transmission fluid in my 99 400 sundancer with 3116 and ZF 800 IV V drives. After a short cruise I noticed about a pint of transmission fluid in the bilge. Then after another short cruise I figured out that it was coming out of the filter cap on Starboardv drive.
The filter cap is a two piece arrangement that when tightened squeezes an O ring out radially so that it tightens against the housing of the transmission. However in my case the cap does not seem very tight and is quite easy to move and wiggle around. I was able to put two wraps of teflon tape around the oring on the cap and get the leak to stop for now, but really need to address the problem correctly.
Questions...
1) When the screw in the cap is tightened, compressing the oring, should you still be able to easily move the cap?
2) The torque spec for the screw in the cap is something is 4-6 ft/lbs, but I hardly get any resistance to the screw until the top and bottom halves of the cap come in contact with each other.
3) The oring seems supple, can they shrink over time? The outer perimeter seems a bit scuffed.
3) I believe that new orings come with a new filter, but nothing is wrong with my filter. Does anyone know where I can get the o rings for the filter cap separately. Anyone know the oring sizes?
Thanks,
Pete
