So I was stockpiling some wet sand today and all of a sudden my machine won't hold tilt. It looses pressure even when empty. What can be the issue? My machine is a cat 226b.

Capped the tilt cylinder and It holds pressure. Where are the check valves located on this machine. Or can someone one post hydraulic schematics.

G..G..G..Granville.........!! Fetch your cloth.

Someone can - but in order to do so requires more detail such as the machine Serial Number.
There are 6 different hydraulic schematics for 226B, with a S/N it would identify which of those 6 the correct one for your particular machine.

Don't lose sight of the pssobility that it could be an electronic issue with the joystick control.

Or even the auto level.

Shan Singh does your machine have this button? Do you get the uncommanded movement with this button in both positions?
