Blanking disc (3TA, 5TA)
Gearbox blanking disc for the 3TA and 5TA, seals an unused bore in the gearbox casing.
This is the blanking disc listed for the 3TA and 5TA gearbox, appearing in the catalog under both its current number, 57-0981, and the older T981 designation. It shows up in the gearbox shafts, bearings and inner cover records as well as the gearbox and casing figures, so it's a small piece that lives inside the gearbox housing rather than out on the case exterior.

A blanking disc like this seals off a machined bore in the casing where no shaft or bearing is fitted, keeping oil in and dirt out. It's not a wear item, but it's easy to overlook when a gearbox is apart for a rebuild since it can get missed or damaged coming out.
Our catalog record ties this one to the 3TA and 5TA gearbox, with entries spanning 1960 through 1966. If you're working on a different model gearbox, call the shop and we'll confirm before you order.
