Mainshaft Gear - 1st Speed is a 29-tooth first-speed gear that runs on the mainshaft within the manual gearbox gear train.

As a non-synchronised constant-mesh gear, it is engaged by sliding dog engagement rather than through a synchroniser hub, providing the lowest forward ratio when meshed with its corresponding layshaft gear.

This gear supersedes the earlier part number 217387.

Frequently asked questions

What is the 501617 mainshaft gear?
The 501617 is the 1st-speed mainshaft gear with 29 teeth, running on the mainshaft in the manual gearbox gear train. It's a constant-mesh, non-synchronised gear engaged by sliding dog engagement, providing the lowest forward ratio. It fits Land Rover Series 1, 2, and 3 gearboxes.
Does the 501617 gear replace the older 217387?
Yes, the 501617 supersedes the earlier 217387 first-speed mainshaft gear. If your parts list or old gear shows 217387, the 501617 is the correct current replacement for the Series gearbox. Both share the 29-tooth first-speed specification.
What are the signs the 1st-speed mainshaft gear needs replacing?
A worn 1st-speed mainshaft gear typically shows as whining or grinding in first gear, chipped or rounded teeth, or trouble staying in gear. Because it's a constant-mesh dog-engagement gear, worn dog teeth cause it to jump out of first. Inspect the 29-tooth gear whenever the Series gearbox is stripped.
