Another dealership assembly blunder? Or new hydraulic fitting type?

[MechanicalGuy]

So I've got a 160hrs on my mx5200 in the last 10 months, and I've never seen what I saw yesterday. I noticed while looking at the loader cylinders, it appears as though the plastic cap was left in place as the fitting was screwed into the cylinder. This looks to have happened on two ports, one port of each of the loader lift cylinders.





So when I bought the tractor, they left the rear remote hardware loose and the first time I operated it, oil went everywhere. I chewed them out for that, they said they needed to bring the tractor in and look it over for anything else. I guess they missed this.

Now I'm wondering if I don't have shredded plastic cap floating all through the cylinders or hydraulic system.

Seriously doubt you can put a fitting into cylinder bung with plastic plug in place.... I am seeing it as a reducer of sorts to reduce larger cylinder fitting down to smaller hydraulic hose fitting....

Poke at it with something sharp (ice pick) and see if its metal or plastic...

Won't float too far anyway. Filter will catch it.

I vote "blunder". Never seen anything like that, and it looks like teflon tape on the fitting too.

I don't see how you could start the threads with a plastic cap on the end.......:confused3:

Kenny... Teflon tape is acceptable on a hydraulic fitting, so long as the tape don't get stretched across the end of the fitting, IOW, the tape starts at least one thread back on the fitting. If it does or does not is conjecture, of course. I use it all the time but then I'm careful and we haven't a clue about the installer do we?

Oh it's floppy rubbery something rather. Those plugs are awfully thin, and it actually felt like a rubber plug, not a plastic plug. I've never seen a legitimate fitting that had a rubber umbrella flange like this, and I've worked in machinery my entire life. I'd bet $1000 that it's a plug.

I agree, that doesn't look right. It seems to be common practice to delegate equipment setup and oil changes to the new guy. (Or the not so new guy who doesn't have s clue)

The first time I heard of Teflon tape being used was in mid 70's we were installing a 12,500 HP turbine Southern N.Mex.
and upon completing the installation. the oil pump was filling the lines and it was a method where each bearing had pressure flow sensors and alarms then shut down if not proper range. all was normal and upon first turning over to check alignment the alarms went off almost at each bearing. removing the bearing housing was a Teflon string blocking. every fitting had to be removed and cleaned off the tape. Every since then have been very careful in using.

Whatever it is, it looks like it was in place when the cylinder was painted. I agree it looks a bit suspect.
