Frequently Asked Questions
Q: How do I know if my gearbox cover o-ring needs replacement?
A: Look for hydraulic fluid leaks around the gearbox area or visible cracks in the o-ring. If your leveling system loses pressure or won't hold level, a worn o-ring may be the cause.
Q: Is this a direct replacement for my EI600?
A: Yes, this is a genuine Dometic OEM part designed specifically for EI600 models. It will fit directly without modification.
Q: Can I replace just the o-ring, or do I need to replace the entire gearbox cover?
A: You can replace just the o-ring. It's a simple seal replacement that typically takes 15-20 minutes with basic tools.
