CNH DOUBLE RELIEF VALVE KIT Installation Instructions (92737090)

Hydraulic gear like this usually lives on tractors, loaders, or construction rigs working in dirt, rain, and cold starts. This manual walks you through how to install and set up the double relief valve kit so the hydraulics don’t spike, chatter, or dump pressure when they shouldn’t. Say you just added a new loader attachment and now the boom jerks at the top of travel—these instructions help you trace the lines, swap in the kit, and verify the system’s behaving before you go back to work.

Applications & Use Cases

• Trace existing hydraulic lines so you can correctly route the new relief valve block without guessing.
• Check port locations and hose orientation to avoid crossed lines that’ll have you chasing weird pressure issues.
• Follow the step‑by‑step to isolate the circuit, bleed pressure safely, and install the kit without contaminating the system.
• Test and verify relief operation after install, so you know the valve’s opening when it should, not when it feels like it.
• Inspect mounting points and align fittings so hoses don’t rub through or kink a month down the road.

FAQ

Q: Is this something I can just read on my phone in the shop?

A: Yeah, it’s usually a standard digital file you can zoom and search, which makes it easier to follow while you’re at the machine.

Q: Can I print a copy to keep in the service truck?

A: You probably can; most folks print the key pages—diagrams, install steps, and test procedure—and stick them in a binder.

Safety Note

Always bleed off hydraulic pressure and verify everything’s de‑energized before you crack any fittings on this valve kit.
