Hi All,
Not exactly 'new' to reading here, but new to posting.
For starters, I am no mechanic, but do a lot of my own work because of where I live.
I have a 2019 B2601/LA435/Grappler with 186 hours. I live rural in the foothills of Colorado close to treeline (9200ft) and have been clearing our property of slash due to dry conditions this year.
Two coupler 'o-ring - type' seals' on the LA435 popped over the weekend (red and blue lines). In addition, one seal on the tractor side became slightly marred (blue).
I have read extensively about complaints on this design/concept, about pressure checks, by-passing altogether, etc. But, are they serviceable?
LA435 side (PN 7J065-85160 - $92.00) seems to not be serviceable, as the 'seal' (not exactly an o-ring) is a polymer collar with an o-ring type seal bonded to the outside. You can access this seal for inspection by placing the JCI connector on a bench and pushing down on the outer steel collar of the connector (i used needle nose). This compresses the internal spring and exposes the seal below the piston head (the piston head on this side does not move).
The tractor-side coupler seal (PN 7J626-85290) can be inspected by using a small screwdriver to push the piston into the coupler, which reveals an orange colar-shaped seal. The coupler can be removed by heating the JCI with heatgun (new tractor - JCI had a hard yellow glue) and removing the snap ring below the manifold frame.
As I mentioned above, this seal was only marred on my blue line. I discovered it after replacing the red and blue couplers on the LA435 side (much slower leak). I was luckily able to remove this orange seal and turn it inside out, which stopped the leak (I know this wont last - part will be ordered soon ($55.00).
My question: These couplers must have other industrial uses. And, I have a very hard time throwing away $250 of parts with 186hrs on them because a 10 cent seal popped (engineered obsolescence or not). Is anyone aware of seals kit for these? Or, other applications where the parts might be cheaper?
I have plenty of pictures if anyone is interested.
Note: It was handy to pour talc over the lower manifold and coupler nuts to identify which coupler was leaking and verify it was from the coupler face and not the JCI.
