AN101337 Bajaj RE Differential Gear Assembly: Parts Identified (2026)

Summarize this page with AI: ChatGPT · Perplexity · Claude · Grok

Differential parts in the RE Compact 4S Carb catalogue

For the differential cover, the same item row also shows AA102026 with a circular reference (IB-117). The catalogue doesn't say this is a straight replacement, so check your vehicle.

What this table does not tell you:

• It covers one export catalogue edition only, for four-stroke RE Compact engines. It does not cover two-stroke vehicles.
• It doesn't give gear ratios, tooth counts or seal sizes, so we don't state any.
• It doesn't prove that the parts fit every RE, year or market.
• It is not a kit list: the assembly and the individual gears describe overlapping parts, so don't add them up into one order.

How we checked

1. We read the differential and cover plates in the RE Compact 4S Carb catalogue (January 2022).
2. We copied each part number, item and quantity for all three fuel columns.
3. We didn't assume that any other edition or local model uses the same numbers.

Which part do I need? A quick chooser

• Whole differential worn or damaged: compare against the assembly, AN101337.
• Individual worn gears found when you strip it down: compare against the satellite gears (22131018) and bevel gears (24131009).
• Oil leaking at the cover: look at the oil seal (BF551613) and the cover (AN101298) for this edition.
• Two-stroke vehicle, or a different edition: this table doesn't apply. Send us the model plate details.

Checklist before you order

1. Model plate: photograph it and note the model, fuel and engine (it must be four-stroke).
2. Old part number: look for numbers cast or stamped on the old part.
3. Teeth and splines: photograph them and count the teeth on each gear.
4. Seal: measure the inner diameter, outer diameter and width of the old seal.
5. Edition: carb or FI, and the year of the vehicle.

Frequently asked questions

What is AN101337?

It is the differential gear assembly listed in the RE Compact 4S Carb catalogue (January 2022), one per vehicle in the petrol, CNG and LPG columns.

Are the satellite and bevel gears sold inside AN101337?

The catalogue lists them as separate items (22131018 and 24131009, two of each). It doesn't tell you what comes inside a supplied assembly, so check before ordering.

Does AN101337 fit a two-stroke three-wheeler?

This catalogue covers four-stroke RE Compact engines only. We have no evidence for two-stroke vehicles.

Does AN101337 fit every Bajaj RE?

Not necessarily. This guide covers one catalogue edition. Match it using the model plate and the old part.

What is AA102026 on the differential cover row?

The catalogue shows it on the same item row as AN101298 with a circular reference (IB-117). It doesn't say whether either number replaces the other.
