Hi all -

I looked for a newsgroup about hydraulics but didn't find one... so here
we are...

We are in the process of repairing a truck mounted hydraulic crane (an
old power company rig that digs holes, sets poles and generally does
lots of stuff).

Yesterday I replaced two of the approximately 3,218 hydraulic hoses on

Izzat about a hunnerd?


the rig and paid about $100 for them. Since there will be more hoses to
replace as we get into the project (and we also have a backhoe with
aging hoses that will need some attention in the future) we are
considering getting the tooling to do our own hoses.

Getting or fabbing, Carla?


The crimping machines seem godawful expensive - and there seem to be two
or three manufacturers (Parker, Weatherhead, Gates, etc.) with
apparently incompatible fittings and crimping dies...

Yes, they are.


Is tooling up for what we want to do reasonable for the amount of hoses
we will be making or is it more cost effective to run down to the auto
parts and have them made for us as needed?

I've always gone to the NAPA a/p for hyd hoses, but those were
one-offs.


Anybody do/done this and have any words of wisdom?

Buying all the dies might cost you as much as NAPA, but if you can fab
most of them and use them in a 10k portapower or beefier press, you
might be spending a whole lot less money. Then again, trial and error
will cost you, too. Why not pick another pair and try to fab dies for
whatever press you have? That's probably the way to go, if you have
unlimited time and limited money.

DO let us know what you end up with, por favor.
