Volvo Penta 3531111 is a genuine OEM nut used in Volvo Penta engine front-end service. The strongest current public parts-diagram trail places this part as schematic object key 27 in a crankshaft and vibration-damper related assembly, where it appears with the crankshaft pulley and vibration damper hardware. That gives it a strong application trail as the retaining nut used at that exact front-end engine position where 3531111 is called for.
Key Features
- Genuine Volvo Penta OEM nut, part number 3531111.
- Strongest current public diagram support places it as object key 27 in a crankshaft / vibration-damper assembly.
- Current automotive Volvo references identify the same number as a damper pulley nut, which aligns with the front-end engine hardware application trail.
- Current public catalog data lists approximate weight around 0.064 kg on one listing.
Engine Compatibility
The strongest supportable fitment trail for Volvo Penta 3531111 is by exact diagram position rather than by a broad public marine-engine list. Current public references place it in a crankshaft and vibration-damper related assembly, and parallel Volvo references identify the same number as a damper pulley nut. The safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the engine being serviced.
Serial Number Fitment Notice
Fitment can vary by engine family, pulley arrangement, and front-end hardware stack-up. Confirm Volvo Penta part number 3531111 against your engine serial number and the correct Volvo Penta parts diagram before ordering, especially on front-end engine assemblies where nearby nuts and fasteners can look similar but serve different pulley or damper positions. That extra check matters here because the strongest public evidence is tied to a specific diagram location rather than a wide published marine fitment matrix.
When This Part Needs Replacement
Replace this nut when the original fastener is damaged, rounded, thread-worn, corroded, stretched, or no longer secures the pulley or damper hardware correctly. It is also a smart replacement during adjacent front-end engine service if the original fastener has already been removed and shows visible wear. This service guidance is based on the part type and its current front-end engine application trail.
Installation Notes
Match this nut to the exact Volvo Penta application before installation. The strongest public reference places it in a crankshaft / vibration-damper related assembly, so confirming both the part number and exact diagram location is the safest cross-check before ordering or reassembly. Inspect the related pulley, damper, and fastening surfaces at the same time to help avoid repeat front-end hardware issues after service.
Alternate/Superseded Part Numbers
Use Volvo Penta 3531111 as the primary ordering number. In the current public sources reviewed, I did not see a stronger confirmed supersession trail than the active number itself.
Parts Desk Insight
Hardware part numbers like this are easy to underestimate because the nut can look generic once it is off the engine. Matching the exact Volvo Penta diagram position first is usually much safer than trying to substitute by thread and wrench size alone.
