Volvo Penta Grooved Pin 24693918

Volvo Penta Grooved Pin — 24693918

What This Part Does

The 24693918 is a genuine Volvo Penta OEM grooved pin. Grooved pins are precision fasteners with longitudinal grooves along the shank that create an interference fit when pressed into a matching bore, providing reliable component location, retention, or pivot function without requiring a threaded engagement. They are used throughout engine and drive assemblies at positions where precise, repeatable alignment between components is required.

Because Volvo Penta uses grooved pins of varying diameters, lengths, and groove configurations across their product range, 24693918 must be confirmed by the applicable parts diagram, engine model, and serial number before ordering.

Compatible Applications

• Volvo Penta engine or drive applications whose parts diagram specifically identifies 24693918 at the grooved pin position

Confirm fitment using the complete Volvo Penta engine designation, engine serial number, assembly position, and OEM part number 24693918. Grooved pins of similar appearance can differ in diameter, length, groove pattern, and material grade — do not substitute based on physical appearance or approximate measurement alone.

Serial Number & Fitment Notice

Confirm the exact engine model and serial number against the applicable Volvo Penta parts diagram before ordering. Grooved pins across Volvo Penta assemblies can differ in:

• Shank diameter
• Overall length
• Groove pattern (full-length, centre, or partial)
• Material and surface treatment
• End configuration (chamfered, radiused, or flat)
• Bore interference specification

Using an incorrect grooved pin can result in improper component alignment, insufficient retention, or damage to the bore in the mating component.

Dimensions

Exact pin diameter, length, and groove specification are not published in the Volvo Penta consumer catalog. Confirm by the parts diagram for your specific engine model and serial number. If replacing a worn or damaged pin, measuring the existing pin and matching to the OEM part number is the most reliable approach.

When to Replace

• Pin is bent, deformed, or broken
• Grooves are worn smooth and the pin no longer retains correctly in the bore
• Bore shows elongation or damage indicating the pin has been working loose
• Corrosion or pitting on the pin shank
• Pin is damaged during component disassembly
• Service procedure specifies new hardware on reassembly

Grooved pins should generally be replaced rather than reused when removed, as the grooves can be deformed by the first installation and may not provide full retention force on reinstallation.

Service Interval

No fixed replacement interval applies. Replace whenever the pin is damaged, shows wear, or is specified for replacement in the Volvo Penta service procedure for the assembly being serviced. As a general practice, replace grooved pins any time they are removed from a precision-fit application.

Installation Notes

• Confirm the pin diameter and length match the diagram specification before installation
• Inspect the bore for damage, elongation, or corrosion before pressing in a new pin
• Use the correct installation tool to press the pin squarely into the bore — driving a grooved pin at an angle can damage both the pin and the bore
• Do not hammer a grooved pin in without a driver — off-axis force can deform the pin and result in misalignment
• Confirm the pin is fully seated to the depth shown in the Volvo Penta service diagram
• Follow the Volvo Penta service procedure for the specific engine model and assembly

Alternate & Superseded Part Numbers

No superseding or alternate number should be substituted unless confirmed by the Volvo Penta parts catalog for the specific engine model and serial number.

Technical FAQ

Q: Can I reuse this pin after removing it?
A: Not recommended. Grooved pins derive their retention from the interference between the groove profile and the bore wall. Once removed, the grooves may be deformed or the bore slightly enlarged, reducing the clamping force on reinstallation. At under $5 each, replacement is the correct practice.

Q: Can I substitute a generic grooved pin of the same measured diameter?
A: Only if the aftermarket pin exactly matches the OEM diameter, length, groove pattern, material grade, and end configuration. In precision engine assemblies, even a small dimensional difference can affect component alignment or retention. Confirm the OEM part number from the diagram rather than selecting by measurement alone.

Q: How many do I need?
A: Check the quantity shown in the Volvo Penta parts diagram for your specific assembly position. This listing is sold individually — order the quantity indicated in the diagram.

Q: How do I remove a grooved pin without damaging the bore?
A: Use the correct pin punch or extractor for the pin diameter, applying force axially. Driving the pin sideways or at an angle risks deforming or enlarging the bore. Refer to the Volvo Penta service manual for the removal method specified for your assembly.

Parts Desk Insights

Grooved pins are the kind of part customers forget to order until the assembly is already apart — at under $5 each, they are worth including in any service parts order when the assembly is known to contain them. The main thing to confirm is the exact diagram position and quantity, since Volvo Penta uses grooved pins of different sizes across their engine and drive assemblies and they can look identical at a glance. Customers occasionally ask about substituting a generic pin — for a precision locating application, the OEM part is the right answer. If the bore is damaged when the old pin comes out, that needs to be addressed before a new pin is installed, as a worn bore will not retain a new pin correctly.
