Description
When you start hearing that telltale knocking sound from your engine or notice the oil pressure gauge dropping during heavy work, chances are your oil pump is telling you it’s time for a replacement. This heavy-duty engine oil pump provides essential lubrication system performance and ensures critical components receive adequate lubrication during demanding agricultural operations. Don’t risk turning a worn pump into an expensive engine rebuild—get that oil circulating properly again.

Built for Real Farm Work
This pump fits a wide range of classic Massey Ferguson tractors including the MF65, MF165, and MF255, along with industrial models like the 30, 40B, 50, 302, 304, and 3165. Whether you’re running a MF165 through hay season, operating an industrial loader, or combining with a 300 S.P., these machines were built to work hard day after day. The A4-203 and AD4-203 engines in these tractors are known for their reliability when properly maintained.
Made to Last
The robust construction withstands the demanding requirements of agricultural use, while quality materials provide long service life, reducing maintenance costs and downtime. TISCO builds their pumps to handle the constant pressure changes and temperature swings that come with real farm work, from cold morning starts to hot afternoon field work.
Good to Know
Drain engine oil completely before installation and ensure all mating surfaces are clean. While you’ve got the pump out, it’s a good time to check your oil pressure relief valve and replace your oil filter. Most mechanics can swap this pump in a couple hours, and you’ll immediately notice better oil pressure readings on your gauge.
