M1-Series Tanks…Screen Strains Debris

Mechanics, when you’re replacing the M1-series tank’s turret distribution valve (TDV), NSN 4820-01-308-1858, be sure to give the inlet strainer screen a good eyeballing.

TDV Screen

That little screen, NSN 4730-01-292-7776, protects the TDV from big problems caused by debris from the hydraulic reservoir. Using a clogged or damaged screen makes the TDV strain to do its job.

Make sure the screen isn’t damaged or blocked by debris. Clean it if needed or order a new screen if the old one’s no longer serviceable.

A new TDV doesn’t come with a screen, so you’ll need to order one separately. Never install a TDV without a screen. And it’s a good idea to keep a few extra screens in your tool truck.
