I have something similar on an ES-B Easi reach truck three motor. The check valve on the reach manifold was also clogged with debris. Cleaned it and fixed the issue, but also noticed it does not retract while forks are on a load. You hear the aux motor running and can feel the hydraulic hoses flexing with pressure. Without a load it retracts, but does not fully nest. Could it be the reach valve that's clogged as well?
Nice Troubleshoot! Have Question ,if the check was ok and the cylinder (reach) was ok and the same thing happen, where do you think you would look next?
I have a Raymond DR25TT, the steering orbital acts like it is not getting enough fluid. When the back is lifted and there is no weight on the unit, I can turn the wheel with the key off and you can feel it keep stopping while turning it. When the key is on same issue just amplified because the pump is on. Seems like the same issue I just don't know where the one way valve is for this section
The one way valve would be in the return section of the orbitrol. Be aware though that a mechanical binding on the drive unit steer ring or in the hydraulic steer motor would produce the same symptom or if the pump is worn.
I’m a new mechanic to forklifts. I tried diagnosing a reach truck that would extend whenever I tried to side shift to the right, or retract whenever I side shifted to the left. Tilt and lift are working just fine. Could it also be the one way CV or would it have to do with the OTM cables? Thanks!
I know this is an "old" video, but I have a similar issue that seems to have popped up out of the blue on my R45TT. When using the reach, tilt, or sideshift, the forks will briefly go up an inch or two. Perhaps coincidently, I raised the forks all the way up and tilted back the day before. Any ideas?
@@forkliftgeek10 thanks for the reply. Yeah, from the diagrams you had in your video it seemed the lift was separate. One other thing I noticed just now, if I lower the mast just slightly, the next tilt/shift/reach will not raise the mast. The second tilt/shift/reach will. If I keep lowering the mast before using the joystick tilt/shift/reach, there isn't ever an uncommanded lift. Still think it is the joystick? Edit: One other thing, a lift will have the same effect, but it has to be a substantial lift, not a small one.
The first thing to do is to make sure the vsm is not receiving a signal from the joystick when it is not supposed to. This is to determine if you have a control problem or a hydraulic ( mechanical) problem.
@@forkliftgeek10 Would you happen to know where the maintenance manual for this might be found? I've only been able to find manuals for similar but not the exact. Also, I could be wrong, but it seems @jemuelvelarde7199 mentioned the same problem as me in the comments for your Encoders on Raymond Easi video. They mention the cold, and while I'm not using mine for cold storage, it is about 55F right now.
If it feels like it's dragging check the brakes. If it is slow and feels like the motor is chattering check the encoder. If it feels normal but just driving slow check height switch (if equipped)
@@forkliftgeek10 okay I'll check all that because all it does is move forward on it's own but slowly and if I hold the handle back to reverse it still feels like it's trying to move forward on it's own. Be right back bro
Shoot, did not quite understand the problem. Sorry. Moving on its own without moving the handle is what you meant.. then I would check the throttle potentiometer.
Working on a Raymond EASi everything works electrically I have up and down on the forks but no extend/retract, tilt, or side shift im assuming im having a hydraulic issue any ideas of which solenoid to look for or check valve?
@@forkliftgeek10 steering works can move machine around everything works normal. Forklift was running fine they plugged it in to charge battery and when went to use had lost tilt extend retract and side shifts
Ok, if power steering is working then the pump is out of the question. If non of the overmast hoses flex when you operate the auxiliary functions then I would look into the directional valve solenoids and wiring for them.
Greetings friends, how are you? I've got a problem with the extension!! When I flip the switch I hear the solenoid activate but the hydraulic motor is not running, is there any suiche that makes the motor turn on when doing the tilt or extension?
The design of the circuit would be different from model to model and brand to brand. If your truck is the same as in the video, if the motor does not run check the contactor and also the motor brushes (if DC).
My dear contactors are active when you step on the dead man's pedal, but when sending the extend command you are not!! My question is what makes the engine start when you hit any switch command
Excellent presentation with schematic and actual photos/video. This is how all hydraulic training should be.
Thank you
Great success. The joy of fixing something and getting it back up and running. I have a Hyundai that drifts down so I have test some stuff tomorrow.
nice diagnoses and fix! thank you.
Great Videos. I’m very grateful for people like you, helping people like me understand. Thanks
Nice work. I have seen the cylinders damaged like that but never seen fragments in the system. I worked at Raymond in LA, CA. for over 20 years.
Steve Mitchem hey I'm a forklift tech in ca what kind of hydraulic gauge did you have?
Great job.
+VideosByAl thanks
Perfeito. Parabéns !!!

Based on the hydraulic schematic the only other possibility would be a crack in the manifold allowing the flow to both tilt and reach cylinders.

What kind of hydraulic pressure tester do you use? Gauge?
+matthew placencia yes
What kind? Brand what's your set up? I need to buy one
+matthew placencia ill take a picture Tuesday

Unplug the solenoid for the side shift and see if it still does it. If it doesn't then it's possible to be the cable or joystick.
@@forkliftgeek10 will do, thanks.

Do you have power steering working?
When you step on the deadman, does the auxiliary motor run? If it is running, when you try to tilt or reach, does the overcast hose flex?
