The Wacker Neuson Roll Pin 4 X 18 is a genuine OEM component designed for the RD7H series tandem rollers and DPU 4045H and DPU 5045H vibratory plates. Sourced directly from Wacker Neuson, this roll pin meets the exact dimensional and material standards set for original equipment, ensuring a drop-in fit without guesswork. It is compatible across multiple RD7H and DPU model variants, making it a practical stock item for operators and service technicians who maintain Wacker Neuson compaction equipment. Confirm your model number against the fitment list before ordering to ensure this is the correct pin for your application.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 4 x 18 mm specification required for correct seating and retention force in Wacker Neuson assemblies.
- Genuine Wacker Neuson Part — Supplied as authentic OEM stock, meaning material grade and surface finish match the original pin installed at the factory.
- Broad Compaction Equipment Fitment — Fits RD7H series double drum vibratory rollers and DPU 4045H and DPU 5045H vibratory plates, covering a wide range of Wacker Neuson compaction machines.
- Secure Component Retention — A correctly sized roll pin holds connected components in alignment and prevents lateral movement; an undersized or worn pin can cause slop, vibration damage, or component failure during operation.
- Direct Service Replacement — Installs into the existing bore without machining or modification, allowing fast turnaround during scheduled maintenance or field repairs.
A roll pin — also called a spring pin or slotted pin — is a small cylindrical fastener with a lengthwise slot that allows it to compress slightly as it is driven into a drilled hole. This compression creates a tight interference fit, locking shafts, levers, linkages, or other components securely in position. On compaction equipment such as vibratory rollers and plates, roll pins are subject to constant vibration and cyclic loading, so using a pin with the correct diameter, length, and material hardness is critical. A worn, sheared, or missing roll pin can cause connected components to shift out of alignment, leading to accelerated wear, erratic machine behavior, or mechanical failure mid-job.
