CNH SECOND OPTION LINE LONG ARM Installation Instructions (91834117)

On most CASE/CNH excavators, that second option line on the long arm is what lets you run breakers, thumbs, tilting buckets—stuff that actually earns its keep in dirt, rock, and demo work. This manual walks you through how to install and route that extra hydraulic line so it doesn’t rub, kink, or leak. Say you’ve just bought a hammer: with this manual you can trace the ports, mount the brackets, align the clamps, and hook everything up so the attachment actually responds when you hit the pedal, instead of just hissing at you.

Applications & Use Cases

• Trace the factory hard lines and verify where the second option kit ties into the main valve and arm plumbing.
• Check bracket locations, then align and route hoses so they clear the boom, arm, and quick coupler through the full stroke.
• Isolate each connection point and inspect and test for leaks after startup, so you’re not chasing hydraulic oil later.
• Follow the steps to bleed air from the added circuit so attachments don’t chatter or move jerky.
• Use the diagrams to identify and replace damaged clamps or guards when you’re repairing the arm in the field.

FAQ

Q: Is this a PDF I can search on my laptop or phone?

A: It’s typically a standard PDF, so you can search text, zoom in on diagrams, and keep it open while you’re at the machine.

Q: Can I print just a few pages to take to the jobsite?

A: Yeah, you can usually print selected pages; most folks print the routing and torque pages, stick ’em in a plastic sleeve, and toss them in the service truck.

Safety Note

Always depressurize the hydraulic system and verify all controls are locked out before cracking any line on the boom or arm.
