P28-2 Stuffing Box hose replacement

[Karl]

Hi All,
What is the method used to get the hub off the coupling end of the prop shaft? Can I use a puller? I need to replace the hose, it is rotten.

Thanks Karl

Based on my experience last year with the 10M, there's little room to get a gear puller in there. I wound up having to cut the shaft. Probably not what you wanted to hear. If the coupling hasn't been off in some time, it's likely pretty fused on.

Cheers,

you can stack nuts or sockets inbetween the the coupler and the engine flange, tightening the coupler bolts will slowly push the shaft out of the coupler.
you'll probably need 3 sets of bolts in increasing length and 3 or 4 nuts to stack.

I've jacked them off using the coupling bolts w/ a socket bearing against the transmission coupling. It took about 8 hours standing on my head. However, if the setscrew can't be removed, forget it. Cut the shaft and buy a new one. If so, replace the hose w/ a PSS mechanical seal.

Assuming there is no setscrew. My guess is a several hour futile fight followed by a Sawsall.

I have plenty of room as you can see and the set screws came out easily. It's that Devine intervention or talking good to it.  Thanks for the help.

Having a newer boat and room to swing a hammer both help.

 

For most applications I suspect Dick Usen's suggestion, is more useful.

Good pictures.
I don't think it's a good idea to use the drive saver to force the coupler off.
I would remove the drive saver and stack against the engine coupling or cut a piece of thick steel to jack against. you might even be able to use c clamps.

Try the socket and long bolts and some PB Blaster. The impossible jobs are sometimes easy, the easy impossible.

[richard usen]

Don't even think about a hammer!!!! I once used a homemade puller, made of 3/4" plate and bent the damn thing!

Chances are pretty good that if the shaft is fused to the coupler it also has enough wear that you shouldn't begrudge the boat a new prop shaft.

And if you take the shaft out in one piece you'll be able to make that decision.
If you cut the shaft it becomes a moot point.

You might try cutting the hose out. Then you can slide the SB down the shaft and check for wear. It would also give you options for where to place that saw *when* you go to cut it out.

I replaced the hose for the stuffing box on my P30 a couple of years ago.  After 30+ years in place, the hose _had_ to be cut out.  It was the only way to remove it.  I used a borrowed puller to pull the prop shaft and removed the shaft and coupling through the engine compartment (that pesky engine was already out of the way).  I brought the shaft and coupling to Dick Usen who used a 20 ton (?) press to get the coupling off.  The 30+ year old, bronze shaft was pitted and worn so I had to buy a new SS shaft and a new coupling (shaft was about $280, coupling was about $40).  I then sailed for a season with the coupling and shaft in place, but still no engine.

Cutting the shaft on the boat would probably have been easier.  BTW, I got $11 for the old shaft from a scrap dealer in Providence.

HTH.

get a slide hammer, that'll remove the shaft .

Is there room for a slide hammer? I don't think it would work anyway.

The trick with a nut or socket can work very well especially in the tight
spaces. From the photos looks like there is a drive-saver flex coupling?
That might be an issue for the nut/socket trick? You might need to take
that off first.

I have a puller that works well with mine. It is a harmonic balance puller
that they have at Sears or Harbor Freight or probably most auto stores? I
am attaching a photo of mine in place on the shaft coupling.

I upgraded the bolts it came with to grade 8. Less worries about bending.
You might need a selection of bolt lengths too. Overall this is the best
solution I have found. It is pretty compact and will not mess things up the
way an impact tool could. Mine was pretty rusty when I pulled it. I
sprayed it with PB Blaster and tensioned it up and let it sit over night.
In the morning it had popped free. So some patience might be good. For
yours you might try to find one with four bolts otherwise you'll have to use
the two on your four-bolt coupler. I think you'll also need a bit more room
that you can get by cutting the rest of the stuffing box hose off and
sliding the shaft aft.

While you have the coupler off and shaft out I would get the coupler faced
by a machine shop. They mount it on the shaft in the lathe and machine the
face of the coupler so it is truly perpendicular to the shaft. Of course
that's hardly worth it unless the shaft is still in good shape. Otherwise
replace it and face the coupler on the new shaft.

Dick U recommended a PSS dripless seal. They are nice. I sort of prefer the
traditional packing gland with a gortex packing. Almost dripless. I am not
so comfortable with the bellows on the PSS. Bigger deal if the fail.

Good photos by the way. I don't like the look of the hose on your strainer.
Not below-LWL grade.

The slide hammer would be used at the propeller end of the shaft, plenty
of room.

Define proper end.

[richard usen]

I've never seen a coupling that's been on for a year or so that came off easily. Once the coupling gets wet and rusts a bit, it's on for good. Sometimes you can jack it off, sometimes not. The trick is to make the right decision before you ruin the transmission coupling. You definitely don't want to use a hammer against the transmission where you can do expensive damage.

[richard usen]

Do you really want to hammer against a ball bearing?
