Truck Mixer Spare Parts Filters BT351

BT351 is a spin-on hydraulic return filter. It’s built for the low-pressure side of hydraulic systems, keeping oil clean before it goes back to the tank. Not a flashy part, but without it, contamination will eat pumps and motors alive.

You’ll find this filter on truck mixers, JCB backhoes, Liebherr gear, and New Holland equipment. It screws onto Baldwin bases OB1313 or OB1314. Thread size is 1 1/4-11 BSP-PL. If your base matches, it’ll fit. No guesswork.

Media is cellulose, nominal 9.8 micron, absolute 27 micron. That means it traps the gritty stuff before it scores valve spools or plugs orifices. For severe duty, we offer the BT351-MPG version with glass media—finer filtration, longer life in wet or acidic oil.

Replaces OEM numbers like JCB 32/901401. Also crosses to Fleetguard HF7980, WIX 51858, and Main Filter MF0593082. So if you’ve been buying those, this is the same fit, same seal, same bypass setting (25 psi crack, 40 psi reseat).

Order BT351 when your hydraulic oil looks hazy or your machine runs hotter than usual. Change it every 500 hours or per manufacturer schedule. Cheap insurance for a $5,000 pump. Keep a spare on the truck—mixer downtime costs more than the filter.
