Multiquip 5228 Grease Zerk 45 1/4-28 Long

The Multiquip 5228 Grease Zerk 45 1/4-28 Long is a genuine OEM lubrication fitting designed for JTO-SERIES and JWN24HTCSL Whiteman ride-on power trowels. As a direct OEM replacement sourced through Multiquip's authorized parts program, the 5228 delivers an exact match to the original component installed at the factory. Verify your model against the JTO-SERIES and JWN24HTCSL fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Grease Fitting: — Manufactured to Multiquip's original specification, ensuring correct thread engagement and grease-flow rate for ride-on trowel pivot points and bearings.
• 45-Degree Angled Body: — The 45-degree offset allows grease gun access in tight or obstructed areas where a straight fitting simply cannot reach.
• 1/4-28 Fine Thread: — Fine-thread UNF specification provides strong bite in aluminum and steel housings, resisting loosening under vibration common to trowel operation.
• Direct Replacement for JTO-SERIES and JWN24HTCSL: — Confirmed fitment for Whiteman ride-on power trowel models; threads in without modification to the housing bore.
• Protects Critical Rotating Components: — A functioning grease zerk keeps bearings, pins, and pivot assemblies properly lubricated; a missing or damaged fitting leads to accelerated wear and eventual component seizure.

A grease zerk, also called a grease nipple or fitting, is a small but essential lubrication port threaded into bearing housings, pivot pins, and other wear points on power trowel assemblies. When a grease gun coupler is pressed onto the zerk, it opens an internal ball check valve and allows fresh grease to flow into the joint, flushing out contaminated or degraded lubricant. The 45-degree angle of the 5228 is specifically designed to give technicians proper grease gun access in confined spaces on the trowel frame. If a zerk becomes damaged, clogged, or stripped, grease cannot reach the joint, leading to accelerated metal-to-metal wear, heat buildup, and eventual bearing or pin failure that takes the machine out of service.
