Correct Size for Stuffing Box Packing in a Bristol 35.5

As the title suggests, it is time to replace the packing when I haul out in a few weeks. Myboat has a 1" shaftand was wondering if anyone knows the correct size packing to order - 3/16 or 1/4?

Any info would be helpful and thanks in advance!

Regards,

Steven

Re: Correct size for stuffing box packing in a Bristol 35.5

I can't remember the size or order since I put a dripless shaft seal on my steel sloop 12 years ago. It has never let so much as a drop of salt water into the bilge.

Doug, Wickford RI

Re: Correct size for stuffing box packing in a Bristol 35.5

If you can tell who made the stuffing box, contact them and ask.
The problem is that it can vary depending on who made the stuffing box. If you don't know who made it, buy some of both sizes and make a note of which size you use so next time you will know.

Go to your nearest West Marine and get packing in both sizes you think you need. Then take the one you didn't need back for a refund. BTW, use the the teflon coated packing and smear it with their teflon lube, so you can get a dripless shaft without overheating.

That's interesting Don, I always thought you needed a slight drip there to keep it cool and lubricated. Also if there is no exchange of water happening, the gland being enclosed and not dripping is there no concern about crevice corrosion due to trapped seawater getting oxygen depleted?

Reason I'm asking is the yard has just change out old PSS dripless seal which had been spraying seawater around the engine compartment at some point. The PO pushed up the thing to try to get it to seal which it did but the squashed up bellows became brittle and cracks in the rubber developed.....so here we are fitting a new shaft and "standard" gland for the long trip home to Austalia.Click image for larger version

Hence I was expecting some, not much, water in the bilge.

My 1" stuffing box uses 1/4" packing and the teflon is working well for me, no heat and no leaks.

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

it's going to be 1/4 or 5/16 in most cases. just buy both.

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

Thanks to all above - I will likely end up taking it apart and measuring.

Regards,

Steven

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

I've found that the combination of the Teflon flax packing, smeared with the Syntef Stuffing Box Lube allows me to tighten the packing gland up enough to cut off the flow of water completely. It gets a little warm at speed, but not hot. No signs of shaft corrosion, as the spinning shaft probably circulates enough seawater in the tube to keep oxygen levels up.

BTW, they sell 1/8, 3/16,1/4, 5/16, 3/8, and 7/16 packing, and I would guess that a 1 inch shaft would be using either 3/16 or 1/4"

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

If it's a Buck Algonquin stuffing box, the packing size for a 1" shaft is 1/4". Just to confuse things, a Buck Algonquin stuffing box for a 3/4" shaft uses 3/8" packing.

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

Thanks to all. I measured and it seemed like 1/4" - received my Gore packing.

Now, I find it is almost impossible to get the stuff inside the packing gland even with the Stuffing tool I made out of PVC pipe. I have read that one is not supposed to put grease in but REALLY, how else might one get this stuff in

Grease it up as good as you can, or as much as you can. But first tap it lightly to flatten it, make it skinnier. Now it should slide in. Most packing glands have a zirk fitting for greasing.

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

I have done a lot of boats with Gore Packing......Never used Grease......

Don't need to. I usually flatten it a little----makes it easier to slide in.....

In my years of re-doing stuffing boxes I can count on one hand the number of stuffing boxed with grease fittings

Re: Correct Size for Stuffing Box Packing in a Bristol 35.5

Perhaps I'm too old school. And maybe a little bit bigger boats. Most of my shafts are 4-6" dia.
