CAT 236 Hydraulic Coupler

Actual Question

Top Replies

I've had this issue before with a similar model. It's usually the coupling. Replacing it is straightforward if you have some mechanical knowledge.

Common problem with these older models. The coupling can fail after significant use. Make sure to check the entire hydraulic system.

Yes, had a couple of these in the shop recently with the same problem. It's usually the coupling. Not a hard fix, but make sure to get OEM parts.

I recommend checking the service manual. It gives a step-by-step on how to replace the coupling. It’s a known issue and relatively simple to address.
