Tech Tips

• ✅ Replace with Every Rebuild: Always change the O-ring when opening the pump seal plate.

• ⚠️ Lubricate Properly: Use silicone-based lube only – petroleum products damage rubber.

• ✅ Inspect Housing: Check pump seal plate and housing surfaces for cracks before reinstalling.

• ❌ Do Not Over-Tighten Bolts: Over-tightening can pinch or distort the O-ring, causing leaks.
