Lubrication and Maintenance

WARNING

Pressurized hydraulic fluid can penetrate body tissue and result in
death, serious infection, or other injuries. Fluid injected under skin
must be IMMEDIATELy removed by a surgeon familiar with this
type of injury. Make sure connections are tight and hoses and
fittings are not damaged before applying system pressure. Leaks
can be invisible. Keep away from suspected leaks. Relieve pressure
before searching for leaks or performing any system maintenance.

The valve block assembly consists of the row marker sequencing and flow control valves in one assembly. Sequencing
valve portion consists of a chambered body containing a spool and series of check valves to direct hydraulic oil flow.

1. Remove valve block assembly from planter.

2. Remove detent assembly and port adapter assemblies from rear of valve block.

NOTICE

Damage to spool may occur if detent assembly and port adapter
assemblies are not removed prior to removal of spool.

3. Remove plug from both sides of valve block and remove spool.

4. Inspect all parts for pitting, contamination, or foreign material. Check seating surfaces inside valve. Replace defective

parts.

5. Lubricate spool with a light oil and reinstall. Check spool moves freely in valve body.

NOTE: Make sure correct check ball(s) and spring are installed in each valve bore upon reassembly.

A flow control valve is located on each side of block assembly. Adjust flow control valves for raise and lower speed as
part of assembly procedure or upon initial operation. If valve fails to function properly or requires frequent adjustment,
remove needle valve for inspection. Check for foreign material and contamination. Make sure needle moves freely in
adjustment screw. Replace defective components.

NOTE: Hydraulics operate slowly when oil is cold. Make all adjustments with warm oil.
