Frequently Asked Questions
Check your unit’s parts manual/diagram. If the bill of materials calls out 100084 (BALL, metallic) in the bypass/check assembly, it’s the correct part. Serial-range revisions can differ, so verify by model and serial number.
Typically within a check or bypass valve in the hydraulic reservoir or valve body (varies by model). It seats against a matching surface to control fluid direction/pressure during operation.
Pressure instability, difficulty holding pressure, or backflow during priming. Inspect the ball and seat for pitting/flat spots and check the spring and retainer for damage or contamination.
Generally no. 100084 Metallic Ball is commonly used in GH hydraulic and LineLazer assemblies (plus some Monark configs). Homeowner series often use different check components. Always confirm against your exact model diagram.
It’s good practice to inspect and replace the seat, spring, retainer, and related seals if wear is present. A worn seat will prevent proper sealing even with a new ball.
