\"143960A1<\/p>\n

Premium Agricultural Sprocket for Case IH Combine Clean Grain Elevator<\/h2>\n

OEM Part Numbers:<\/strong> 143960A1 \/ 165292C1 \u00a0|
\nTeeth:<\/strong> 9 \u00a0|
\nBore:<\/strong> 1.375\u2033 (35 mm) \u00a0|
\nWeight:<\/strong> 1.561 kg \u00a0|
\nMaterial:<\/strong> Forged Carbon Steel<\/p>\n

The 143960A1 is a forged carbon steel agricultural sprocket<\/strong> designed for the clean grain elevator drive on Case IH 2188 and 2388 combine harvesters. It also covers the 2100 and 2300 series where the same elevator chain drive geometry applies. The 9-tooth profile fits a 1.375\u2033 diameter shaft and transmits header drive torque through the chain to the clean grain auger working assembly. This part directly replaces OEM numbers 143960A1 and 165292C1 under a single stocked unit.<\/p>\n

What separates this unit from standard aftermarket alternatives is the induction hardening process applied to the tooth flanks after hobbing. Induction hardening heats only the tooth surface zone to hardening temperature \u2014 leaving the core microstructure unchanged \u2014 which produces a wear-resistant case over a tough, impact-absorbing core. In grain elevator service, where chain tension spikes every time a loaded flight engages the sprocket, that combination of surface hardness and core toughness matters more than bulk hardness alone.<\/p>\n

The outer surface is painted for atmospheric resistance, protecting the part during off-season storage when grain dust and moisture accelerate corrosion on bare steel components. Custom specifications \u2014 bore diameter, tooth count, hub configuration, or alternative surface treatments \u2014 are available for non-standard applications.<\/p>\n

Cross-Reference: Replaces OEM Numbers 143960A1 & 165292C1<\/h2>\n

This combine harvester sprocket<\/strong> consolidates two active OEM part numbers into one stocked unit. If your parts catalogue, combine service manual, or dealer system shows either reference, this is the correct replacement.<\/p>\n

\n
\n

143960A1<\/p>\n

Original Case IH part number. Used in service manuals for the 2188 and 2388 combines and the 2100 \/ 2300 series headers.<\/p>\n<\/div>\n

\n

165292C1<\/p>\n

Superseded OEM number. Older parts systems and dealer catalogues may still list this reference for the same elevator sprocket position.<\/p>\n<\/div>\n<\/div>\n

If you are unsure which number applies to your machine, send your combine serial number and we will confirm compatibility before your order is placed.<\/p>\n

Superior Durability with Induction Hardened Teeth<\/h2>\n

Not all agricultural sprockets are hardened the same way. Through-hardening raises the bulk hardness of the entire part, which increases brittleness and the risk of tooth fracture under impact load. Induction hardening \u2014 the process used on this unit \u2014 selectively heats only the tooth surface to hardening temperature using a high-frequency electromagnetic field, then quenches rapidly. The result is a hard wear layer at the tooth flank and root, while the core retains the toughness of normalised carbon steel.<\/p>\n
