Never implied it was a big deal, it was an easy enough fix and if that is the worst thing that happens I sure can live with it. Actually we should be great full they put zerk fittings in, most manufacturers todays whether it be automobiles trucks etc. do not even use zerk fittings. I did have another problem, the heavy hydraulic line under the tractor was leaking at one of the crimps. The hydraulics shop would not re-crimp the hose, I had to buy another one and discard a perfectly good hose and fittings that I believe could have been repaired.
Mark,
I thought that I wrote my response in a way that you would have realized I was just kidding.
Case has been using press-in zerks for ages. Only occasionally do I read a post where someone has had one come out. In other words, they work 99 percent of the time. When a hydraulics shop says no to your request, then that's the time to go to another shop and see if they say no but only after asking the first shop the reason why behind the no. Because I did not have an answer to this question, I called my hydraulics guy at Princess Auto and this is what he said. Hoses vary in outer diameter from manufacturer to manufacturer and the fittings they carry will not always work on hoses that customers bring in for repair. Their machine is designed to crimp their own line of fittings plus two other brands. if I brought them a hose that they had made, then they would re-crimp it at no charge but they cannot guarantee that the re-crimping would solve the problem.
Head office for PA has laid down the law on this issue for liability reasons. The crimping machines come with an instruction book that tells the operator how to set up for each crimp, depending upon the fitting selected and the hose used. This way, the correct amount of pressure is exerted on the crimp-barrel to prevent hose blow-off. The guy who said no was probably right in doing so. However, my guy at PA says that they stock a bunch of fittings that don't need a crimping tool. The old fitting can be removed carefully by splitting the crimp-barrel in several spots and then prying it away from the hose. Inspection of the hose end would then determine if the other fitting style would work or not.
The questions then become -
Is the correct fitting available in the other style?
Would you have to use more than one fitting to solve the problem?
If so, would the extra fittings cause a clearance problem or an overall hose length issue?
And finally, how much do the extra fittings add up to compared to the cost of a new hose with crimped fittings?
I totally understand your unhappiness at tossing out a hose that appeared to be perfect except for a bad crimping job but those who are in the hydraulics business take safety to be an important factor when making such decisions.
