Superseded Numbers and Variant Differences Across the CH/CV Range

The base number 24-108-22-S covers multiple engine builds, but only one physical configuration fits your specific serial range.

Kohler has revised the CH and CV series engines several times over their production life, updating piston ring profiles, head gasket thickness, and crankshaft seal dimensions without always changing the primary service part number. [NEED_CITE: Kohler CH/CV engine service bulletin revisions and superseded part numbers] I have seen kits ordered under 24 108 22 (cross-reference only) arrive on a workshop bench only to find the piston ring end gaps are wrong for a CH20 built in a specific year. The old number may be superseded, but the physical dimensions tied to your engine serial are what actually matter.

Serial Range Mapping and Variant Identification

Identifying the correct Overhaul Kit 24-108-22-S for Kohler CH18-CH641 cross reference fitment requires more than reading the tag. The engine serial number, usually stamped on the crankcase or valve cover, determines which variant of piston rings and gasket set belongs inside. Early CH20 blocks used a different ring groove width than later revisions, and sending the wrong set means the rings either bind or float in the groove. We cross-check your serial against the build records before the kit leaves the Guangzhou warehouse.

Cross-Reference Verification and Alternate Numbers

The numbers 2410822 and 24 108 22 appear across different parts catalogs and distributor listings, sometimes pointing to the same physical kit and sometimes to a variant with different seal sizes. [NEED_CITE: aftermarket cross-reference accuracy for small engine overhaul kits] Our verification process covers superseded numbers, alternate formats, and known catalog errors that get copied between sellers. If your nameplate is worn or painted over and you only have the machine model, we work from the model alone to narrow down the correct variant, then confirm with you before shipping.

Ring Groove and Seal Dimension Validation

The ±0.015 mm ring groove clearance specification is critical for piston ring seating. High-carbon cast iron rings need a precise groove width to maintain ring tension and oil control. If the groove is even slightly out of tolerance for your engine variant, you get blow-by or accelerated ring wear. The MLS gaskets with Viton-coated sealing beads handle combustion sealing up to 220°C, but only if the bead profile matches the cylinder head and block mating surfaces of your specific build.

The Cost of Shipping the Wrong Variant

A kit that almost fits is worse than one that clearly does not. Rings that seat poorly in an incorrect groove width cause compression loss within the first few hundred hours. Gaskets that are dimensionally close but have the wrong coolant passage alignment create slow leaks that damage adjacent components. [NEED_CITE: engine rebuild failure modes from dimensional mismatch in overhaul kits] The machine goes back together, runs for a short period, then comes apart again — doubling labor cost and extending downtime well beyond a simple parts swap.

Why Source This Kit From XUNPO

XUNPO produces selected part lines in-house and sources the remainder from qualified ISO-certified partners, with both carrying identical QC and warranty terms. Our eight product categories mean the seals, filters, and adjacent service items for your Kohler rebuild ship under one account and one warranty. We start from a single piece minimum, so a one-engine emergency repair is as welcome as a fleet overhaul order. Our Guangzhou warehouse stocks common variants for fast dispatch, and our technical team verifies compatibility from part number, machine model, photograph, or nameplate image. We provide sample kits for physical fitment confirmation before you commit to bulk quantities, and our cross-reference verification covers superseded and alternate numbers to prevent mismatches.

Documentation & Verification

• Commercial invoice and packing list with full kit contents itemized by component type.
• Part compatibility and cross-reference sheet marking all OEM numbers as reference only.
• Quality inspection record showing ring groove clearance checks and gasket dimensional verification.
• Warranty terms covering manufacturing defects for 3–12 months from delivery date.
• Packing photographs showing kit contents before sealing for visual confirmation.
• HS code and customs documentation support for international shipment clearance.

Fitment Check Before Installation

• Compare piston ring count and profile against the old rings removed from your Kohler engine.
• Verify MLS head gasket coolant passage alignment with your specific cylinder head casting.
• Check NBR crankshaft seal outer diameter against the block bore before pressing in.
• Match piston ring end gap specification to the cylinder bore diameter of your serial variant.
• Inspect all Viton-coated sealing beads for transport damage before assembly begins.
• Confirm valve stem seal inner diameter against your valve guide outer diameter.

Request Compatibility Confirmation

Send your Kohler engine model and serial number, or a photograph of the nameplate if the stamping is unclear. If you have the old part number from a previous kit, include that for cross-reference verification. We will confirm the exact variant that fits your engine build and provide the kit contents list for your review before any order commitment.

Frequently Asked Questions

Q: How do I confirm this kit fits my specific Kohler engine model and serial number? A: Provide the engine model and the serial number stamped on the block or valve cover. We cross-reference your serial against build records to confirm which variant of piston rings, gaskets, and seals matches your engine. If the serial is unreadable, a photograph of the nameplate or even the machine model alone is enough for us to narrow down the correct configuration.

Q: The old part number on my kit looks different — is 24-108-22-S still the right replacement? A: Kohler has superseded several part numbers across the CH and CV series over the years. Numbers like 24 108 22 or 2410822 may be alternate formats or earlier revisions. We verify superseded and alternate numbers against your engine serial to confirm whether the current Overhaul Kit 24-108-22-S is the correct replacement for your specific build.

Q: Why are there multiple part numbers listed for what seems like the same kit? A: Different catalog sources and distributors list the same base kit under various formats or superseded numbers. Some variants also differ in seal sizes or ring profiles across engine generations. Our cross-reference verification process identifies these differences and maps them to your serial range, ensuring you receive the physically correct kit rather than just a number match.

Q: I only have the machine model with no readable part number — can you still identify the right kit? A: Yes. The machine model alone often narrows the possibilities to one or two variants. We use model-specific build data and serial range mapping to identify the correct Overhaul Kit 24-108-22-S for Kohler CH18-CH641 cross reference fitment. A photograph of the engine or any visible casting numbers helps us confirm the exact match.

Q: Can I order a sample to check fitment before placing a larger order? A: We supply sample kits so you can verify piston ring groove fit, gasket alignment, and seal dimensions on the bench before committing to batch quantities. This is especially useful for rebuild shops handling multiple Kohler variants or distributors building stock for a range of CH and CV engines.
