Anyone ever encountered an oil/grease leak on the motor/gear reducer unit on joint number one? Looks like the maintenance manual specs Multitemp FZ grease which looks like it might be a 00 grease? If anyone has any info on repairing this issue it would be greatly appreciated.
ZZX165U JT1 Oil Leak

- Thread is Unresolved

I've only ever used the grease stated in the manual - Multemp FZ.
As far as leaking, only come across one instance of this many moons ago which required full removal of the top casting.
- De harnessing of the complete arm back to the 1FG board.
- Removal of counter balance and H link.
- Removal of JT3 assembly (leaving all minor axis).
- Removal of JT2 assembly.
- Access full top of JT1 casting to access components.
- Hoist and A frame used.
What is the exact part no. of the ZX - ie ZX165U-A001?

I've sent you something via conversation, may help ascertaining where the leak is coming from and also if you require to strip it down.

Thank you, that is exactly what I was looking for.

You're welcome, hope it helps.....

So to disassemble the base:
1. Everything running back to the base of the robot has to be disconnected.
Is there anything attaching the top half to the base of the robot?
Can I just pick the top half off with a forklift once the wires and pneumatic lines are disconnected?

I cannot 100% recall, talking a good 10 years ago.
Not sure about any short cutting.
I think it would be possible to leave all the harnesses running through the centre, if you've got a stable A frame to lift it all up.
I am pretty sure there are some retaining bolts on the top of the casting going into the main gearbox underneath and then I think it should come off with the required lifting gear. K301 on page 18.

Also K302.
All the Kawasaki harnesses have white lines on them for the bracket locations, but I paint pen all harnesses before removing any of them to assist with relocating.
If memory serves me, the whole arm has to be at mechanical zero (JT1/JT2/JT3 specifically) before removing anything and isolated/locked out electrically.
In addition to this, I think JT2 has to be in a certain position in order to remove the adjoining gearbox and also the counter balance (requires retaining bolts in the rear) in order to remove as it has 2 springs in there compression and tension and some retaining bolts may be under it too.

I was able to remove the lower guards yesterday and discovered that the fitting that connects the line to the grease fitting on the bottom of the gear box had broken off. Simple fix, I removed the broken fitting and screwed the grease fitting directly into the gearbox. I filled it back up with grease and its good to go.

Excellent news...........
Many thanks for reporting back your findings and resolution, not a common fault, so others will benefit from your feedback.....I know I have, now added to the little black book.
Much appreciated.

Kind of a bad design with the remote grease fitting and the plastic connectors. I'm sure the grease caused the plastic to fail. If anyone ever changes the grease in the J1 gearbox I would put the grease fitting directly in the gearbox or use some SS line and fittings to connect it.
Thanks for your help! After looking at the parts manual Monday afternoon I was suspect/hoping that the oil line was the failure point so I didn't have to disassemble the robot. I appreciate the info for the disassembly, thankfully I didn't need it this time around.
-
You're welcome.
To be honest in hindsight, very logical thinking to remove the skirt for an inspection, I missed that, so thanks for the 'thought process adjustment'.
The info for disassembly is good to keep hold of for future, let's hope you don't need it.
