Re: Stuffing box problems

Colin can come across a little short and over confident, but he has had lots of experience with IP's...even has a youtube video or two on various IP repairs.

I love IP's but access to the stuffing box, chain plates and tanks are not as easy as they could be! Be patient.

Re: Stuffing box problems

Looking at the location of the stuffing box, there doesn’t appear to be a lot of room to swing those wrenches. And obviously you have to turn one full castellation each time. So what I would do is go and buy a ring spanner (not sure what you would call it in the US) that fits and cut out a portion of the ring big enough to allow it to go over the shaft.

Ring spanners are generally double-hex so each castellation is 30 degrees and not 60 as with your wrenches. This will give better access to the nut and will be an easier fit in the small space you have. Will also enable better positioning of the nut when adjusting the packing. A ring spanner that size will have a nice long shank for better leverage and a stout ring that won’t easily be deflected.

Another thing to consider is that turning the outer (main) nut before the lock nut is loose is counter-productive. Use a centre punch/hammer and knock that nut loose (counter-rotational) prior to trying to loosen the outer nut. That’s probably already been done, apologies for stating the obvious.

Re: Stuffing box problems

Ring Spanner = Box End Wrench.

I made my own wrenches, but Amazon carries "service wrenches" that work in tight places.

Re: Stuffing box problems

Cassidy, I think that Cutting a 1.25” hole in a 2.25” wrench doesn’t leave you much overlap to grip the nut, but I might try that idea if all else fails.

Be kind, for everyone you meet is fighting a hard battle.

Re: Stuffing box problems

What he is describing sounds like a flare nut wrench only they don't come that big so you have to make your own.

Re: Stuffing box problems

Hey this is something off topic but i need your help in regarding buying some power tools for my ketch as i am facing some problem while starting it and the engine stops working after 5-10 mins so can anyone suggest me some tools which will be required to repair it or should i repair it myself or should i take it to the mechanic. I have read this guide about tools but couldn't able to find anything specific , I am looking forward to have some tools list and also suggest me good brands.

That’s exactly what I was alluding to. On a large wrench, the wall thickness is substantial and thus pretty strong, certainly I reckon it would be stronger than the open ended wrenches shown in other posts even with a part of the ring cut away.

To be fair the flare nut wrench shown (I know them as pipe wrenches) are much thicker in the ring area than a normal wrench.

This is a pipe wrench. The advantage that flare wrenches have over open end wrenches is that they grip more than two flats of the nut. They are obviously not as strong or stiff as a box end but they do work well at their specific function.

We could probably spend a week discussing the differences between your understanding of what things are called and mine. But I won’t other than to say the picture you posted as a pipe wrench, I call a stilson wrench (after the person who invented it).

In fact, other than on this forum, I never refer to a wrench unless it’s a twisted ankle or similar. Every other “wrench” in my life is referred to as a spanner.

Arthur C Clarke wrote a short story that was just a setup for the pun "star mangled spanner."

But I never really thought it worked, because "Star Spangled Banner" is an American song, and of course we call them wrenches not spanners.
