About this part

The 394018S is the square filter found on Vanguard V-twins and the 12.5 to 20 HP L-head twins that John Deere put in its GT235, LX288 and Sabre tractors. It is a big filter on a big engine, and it should be changed every season.

We add the foam pre-filter and a 492932S oil filter so the service is complete. The full list of 290000 to 422400 series engines is on the page.
