Re: Case/Davis trencher backhoe
From the condition of those notches, it looks like someone got in that cylinder with a hammer and punch before... I'm not sure the "right" wrench would grab on nicely any more.

Re: Case/Davis trencher backhoe
A spanner wrench is a hook shaped wrench. Using a punch and hammer is what was probably used and could be used again. Harry

Re: Case/Davis trencher backhoe
Eugen, I have about 15 spanner wrenches. 1 should fit your gland nut. I have a job coming up at Atlantic in about a week.

Re: Case/Davis trencher backhoe
Yes, found an OTC spanner wrench of decent quality on amazon for about 100. Not pulling the trigger year.
@Toolslinger yes, I still hope the spanner wrench can do it.
@Spike188 thank you for the offer, normally I do not refuse borrowing a tool but when hammers or extension pipes are involved I must refuse, I'd hate wrecking a friend's tool.
I'll figure something out.

Re: Case/Davis trencher backhoe
Thanks Dave, I'll measure and let you know. I think it's between 3 and 3.5"
This is the OTC tool, I'm thinking of making the hook from a piece of pliers, so it's a harder steel. And weld it to a piece of quarter inch plate.

Re: Case/Davis trencher backhoe
@Eugen There is a way to make a tool that catches all 4 points at the same time from 1/4" plate .

Re: Case/Davis trencher backhoe
@Eugen these spanner wrenches are seriously heavy duty. Old school from a garage sale. You gain points if you can break it. The offer is still on the table.

Re: Case/Davis trencher backhoe
As others have said, it's not that hard to fabricate something to work as a one off spanner wrench - every heavy shop I've worked in has a stash of "special" hand made tooling (always hidden from the Health and Safety guys - 'cause... you know...)
Piece of plate steel with a notch cut out to go around the rod, holes drilled for hardened key stock welded on the backside to give you the "Teeth" to match up with the notches - and you can put an old bit of rubber hose or something similar around the rod for protection in case the spanner slips so you don't dent the chrome.
More challenging ones have round pin holes in the face of the gland - same idea just using hardened bolts - cut the threads off and use the remaining solid shank for the pin...
If the notches are really bad and you can't get a grip most every hydraulic shop will just break out a big assed pipe wrench (or ViseGrip chain wrench) and grab the sides
