The Wacker Neuson Bolt, Drain Plug, 12x15 is a genuine OEM component designed for CT36 and CT48 series walk-behind trowels, PT3A centrifugal trash pumps, BPS 2550A vibratory plates, and a broad range of additional Wacker Neuson equipment. Sourced directly from Wacker Neuson, this drain plug bolt is manufactured to the exact thread specification and dimensional tolerances required for a proper, leak-free seal at the drain port. Confirmed fitment spans the CT36AGP, CT36AGT, CT36AVP, CT36AVT, CT48ADP, CT48ADT, and CT48ADT-E model families, along with the PT3A pump, BPS 2550A plate, MPU 29A reversible plate, and HPG50 and HPG100 vibratory truss screed power sections. Using part number ensures you receive the exact bolt specified for your machine — no guesswork, no sizing concerns.
Key Features
- OEM Thread and Dimensional Accuracy — Manufactured to the precise 12x15 specification, this bolt seats correctly against the drain port sealing surface to prevent oil or fluid seepage under operating conditions.
- Direct Drop-In Installation — Threads directly into the existing drain port without retapping or modification, replacing the original bolt on a like-for-like basis.
- Wide Wacker Neuson Fitment — Compatible with CT36 and CT48 walk-behind trowel families, PT3A trash pumps, BPS 2550A vibratory plates, MPU 29A reversible plates, and HPG50/HPG100 screed power sections.
- Leak Prevention at the Drain Point — A correctly torqued, undamaged drain plug bolt maintains a tight seal during operation; a stripped or missing bolt risks uncontrolled fluid loss and accelerated component wear.
- Genuine Wacker Neuson Part — Supplied as genuine OEM stock, carrying the same part number — 5100071570 — used by Wacker Neuson dealers and service centers worldwide.
A drain plug bolt secures the drain port on an engine, gearbox, or pump housing, allowing oil or fluid to be retained during normal operation and released in a controlled manner during scheduled service. The bolt's thread pitch and seating diameter must match the housing exactly — an incorrect or worn bolt will not torque down to the proper clamping load, leaving the drain port vulnerable to leaks that can go unnoticed until significant fluid loss has occurred. Replacing a damaged or missing drain plug bolt promptly is one of the simplest steps in protecting the internal components of the host machine from premature wear caused by low fluid levels.
