More trouble with the L3600 - the loader control valve issues.

[Nickk]

I think it is how I am using it but I think it is allowing to do this because of an issue.

75% the loader controls work exactly as they should; but every now and then I am surprised.

1. Occasionally pulling back gently and slowly on the lever will cause the loader to drop and then it goes up as it should. Does not happen every time.

2. Sometimes when pushing the lever forward it will raise and then as the lever is moved further forward it will lower.

As always everyone's ideas are appreciated!

Sounds like a an issue with the load check on the boom spool.

What model loader?

I would remove and clean the load check poppet and spring along with the cavity in the valve. A new poppet and spring is a whopping $20.

Nice great advice.
The poppit is under the circular cover on the left?

Go to the components diagram. Poppet and spring - I think its 110 and 120.

Sorry for being a little dense. It looks like poppits are under the connector for hoses.

Load checks are in the valve body between the service ports. I cant tell exactly where they are installed from that diagram but I am pretty sure thats the load check. What else could it be?

You have to split the sections like the pictures to get to the load check poppets, they are on the sides of the valves.
