Caltric Deck Wash Water Port Plate Compatible with John Deere Z325E Z330 Z335 Z345 Z355 Z365 Z370

What It Is

The Caltric Deck Wash Water Port Plate is an aftermarket replacement part designed to attach a garden hose to the underside of a zero-turn mower deck for cleaning. It’s intended for John Deere Z300 series mowers with 48-inch or 54-inch stamped decks.

Fitment & Compatibility

Before buying, confirm your mower model matches the listed compatibility: John Deere Z325E, Z330, Z335, Z345, Z355, Z365, or Z370. These models share the same deck wash port assembly. Measure your existing port plate—OEM John Deere part number is usually M156622. The Caltric plate should be a direct bolt-on replacement, but verify the bolt pattern (typically two screws) and port diameter (standard 1/4-inch NPT thread for hose adapter). If your deck uses a different port style (e.g., a quick-connect or no port at all), this won’t fit.

Key Things to Buy

• Quality concerns: With a 1.0-star rating from 2 reviews, expect potential issues—reports suggest the plastic may crack or the seal leaks under water pressure. Check for thin molding or rough edges on arrival.
• Installation difficulty: Easy—remove two screws, swap plates, reattach. But you may need thread sealant tape on the hose adapter to prevent leaks.
• Common gotcha: The included hardware might be metric or low-grade; use your original John Deere screws if they fit. Also, the plate may not align perfectly on all decks—test fit before tightening fully.
• Warranty/return: Caltric parts often have limited support. If it fails, you’re likely buying another.

Should You Buy It

Skip this unless you’re on a tight budget and can’t find an OEM replacement (John Deere M156622, ~$15–20). The poor reviews suggest reliability is low—you’ll probably save frustration by spending a few dollars more for the genuine part. It’s only worth it if you’re comfortable patching leaks or replacing it again soon.
