Many owners struggle to attach, and sometimes detach, the flat face hydraulic couplers on attachments. Mike from Rippa USA Sales shares a simple trick, and explains why it works with any excavator, skid steer or mini skid steer, not just Rippa.
STEP 1: RELAX THE HYDRAULIC SYSTEM
Trapped pressure is what makes couplers hard to push on. Set the attachment on the ground, shut the machine off or turn the hydraulic pump off, and move the control levers so the pressure in the lines is released. This works on any brand of equipment.
STEP 2: USE A QUICK GRIP CLAMP
If the coupler still will not connect, use a quick release bar clamp.
- Grab the edge of the coupler with the clamp and squeeze the trigger to push it on.
- Releasing is easy: just squeeze the release.
- A smaller clamp is easier to handle. They cost only a few dollars at a hardware store, so buy a good brand when they are on sale.
WHY RELIEVING PRESSURE MATTERS
Every hydraulic cylinder has at least two lines: one to send oil to it and one to pull oil back. It is a closed system, so pressure can stay trapped in the lines. Forcing a coupler against that pressure can stress the seals inside the cylinders, so relax the system first.
Do you have a favorite trick for stubborn quick connects? Mike invites you to share it in the YouTube comments.
