Thanks Dave :D

These packing glands are getting hard to find. I believe all the rudders shafts are 1" dia.

I would have to consider going with bronze if I replaced my rudders with new stainless ones. Rudders are never really isolated due to linkage etc. and that is why we put anodes on them.

safe boating,
dave

Does plastic hold up on these or is brass a better material???

Brass is tougher, for sure, but be careful to isolate it thoroughly!

Note that, unlike a prop packing gland, you can tighten the hell out of a rudder packing gland since it doesn't spin at high rpm.

I replaced the plastic rudder stuffing box with a bronze stuffing box. Why? My 69 year old dad was helping during the rudder bearing replacement. He loosened the clamps to remove it, applied very little force and it snapped off.

Some forum members have commented about corrosion caused by bronze contacting the aluminum. This isn't true. The bronze is isolated from the hull by the rubber hose. The rudder is isolated from the bronze by the packing material.

If you are using these rudder stuffing boxes in place of the plastic original ones :o make sure you get the correct size rudder hose for attaching the new box to the OD of the Aluminum rudder tube. ;)

My boat has bronze glands on it. They had to be replaced, but that is another story. What had happened though, is the aluminum upper support bracket had come into contact with the packing nut. The support corroded so bad, I had to replace the one. I was able to clean up the other, rotate the support bearing and drill new mounting holes. Both had new isolation gaskets between the bearing and support installed. I think most of this occurred when my boat was in salt water.

So...
Because of damage that occurred while boat was on hard -> bent rudder shaft...
Stbd Rudder - bent n out - f.jpg
...it was necessary to remove it for repair / replacement at a local machine shop.
Extraction was deceptively easy.
- Remove 3 cotter pins. (1 on shaft's top, 1 which tied to packing gland plastic nuts sections together, 1 on "Y" yoke's (ties starboard and port rudders together) clevis pin <removal for ease of access into aft bilge area to work>)
- Hit all parts with PB Blaster a couple of times.
- Easy to then work square headed retaining bolt from bronze tiller yoke.
- Remove brass 9/16" bolt from brass tiller yoke.
- Drive flat tipped screwdriver into split of yoke's split drawtite section. (only enough to effect a loosening of tiller yoke from rudder shaft. Will need to be tightened slightly with screw clamp to ensure alignment of holes when bolt inserted < 1/2 of split section is threaded [in addition to having a 9/16" brass nut as well] so the alignment is correct when starting to thread in bolt.>)
- When tiller yoke's retaining bolt and split was loosened, it was easy to tap the yoke upwards off of shaft - WHICH FELL THRU SHAFT LOG WITHOUT ANY EFFORT onto the ground. This tells me the cutlass bearing's worn out.

- Loosened all 4 screw clamps from isolation hose.
- Pulled plastic "isolator" packing gland assembly.
Rudder - disassmbly - isolator - top ring - f.jpg
The brass "tiller yoke" which connects the rudder to the connection rod between the starboard and port rudders rides on top of the packing gland / top plastic ring.

- Took apart packing gland:
Rudder - isolator - complete disassmbly -f.jpg
Dis-assembly would be left to right - AND THIS IS WHERE I NEED HELP!!! :roll:

I know there're non-metallic cutlass bearing sections still in the shaft log that need to be removed. That I believe I've got a handle on.
--> What I don't know about is the packing gland material to be used in the packing gland.
- Those are the 2 pieces - 2nd from left & 4th from left (or the 2 items between the metal ring).

Anyone know the appropriate material to use? Or would the same material used in the prop shaft log packing gland be used?

Thx,
Bill

Yes, the same packing. A plumbing or boat shop will have different types. I believe 1/4" by 1/4" is the size. Not high pressure or high speed so it is not critical. Just no room to work.
