The GC1705 has been sitting WAY too much since I bought it in 2017 (60 hours). Looked at trading in for a 1725MB but have decided I can get more for my money with DIY mods.
Starting this thread to document progress over the next few weeks but plans are this:
1: SSQA dl95 adapter, mine currently has a pin on bucket. Already ordered this and should have within a week or so. Eventually I will weld on a plate to stock bucket, but this will be lower priority as it doesnt get used much.
2: True 3rd function Solenoid controlled hydraulic valve (HSV) for working a grapple.
3: Coming off the HSV, i will plumb in another handle controlled valve that will be rear remote set for working a hydraulic top link.
4: If this all goes well, and I can afford it....ill likely invest in the Cold Roll Industrial Grapple.
I have been looking for a specific fit hydraulic kit since I bought this, and they just don't exist. I figured, if I can accomplish this, it will be good to document where it may be useful to others. Updates to follow soon.
Thank you @07keo02
- this thread has been very helpful in my pursuit to add rear remotes to my GC1725. The
GC1725 is somewhat different than your tractor as the FEL valve assembly is different and located under
the right fender – but the theory should basically be the same. My objective is not exactly the same as
everything documented in this thread to date: I’m trying to add a set of rear remote valves only (I already have
a 3rd function diverter kit that I’m happy with). My GC1725 has NO BACKHOE as well. I’d like to run a
few things by you and the community to see if I’m tracking everything needed to be successful:
1.) High level system schematic. See attached pictures – just want to make sure I have this right.
The key is that I believe the rear remote should be added in series on the Power Beyond line
between the FEL valve assembly and 3PH. Let know if something is off here.
2.) The P, T, and PB lines coming from the FEL are hard-lines (no soft-line connections like in the
earlier GC1700 series tractors apparently). My thought was replace the entire PB hardline and
insert the rear remotes valves in series. The new lines would all be hoses as that would be
easier for me. I’m not 100% sure which line is the PB line as they’re not labeled. See diagram
from the service manual below. Anyone know which one is the PB? I believe it’s #2, but I’m not sure.
3.) Has anyone confirmed whether this port goes to tank? Alternatively I’m sure I could tee into the
existing tank line, but I’d rather go directly here... one less thing to mess with.
4.) Does anyone know what threads the P, T, and PB hard-lines are? Are they -06 BSPP on the 1723/1725 series as well?
Thanks again any help!
