[TR] TR4A - Gearbox Filter

[Randall]

> Does the gearbox on a TR4A, with A-type OD, have an oil filter?

Only the filter screen in the OD and the magnets under it.  When you remove
the big brass plug on the bottom of the OD, the magnets usually stay in the
plug and the screen falls out. (On the later A-types.  Earlier ones had the
screen held in with a bolt and no magnets.)

They doesn't usually need to be replaced, just cleaned.

However, I believe most of the usual suspects should have replacements if
yours are damaged.
