What is the purpose of thrust washers in an engine?

Thrust washers are small metal components that fit around the crankshaft. Their main job is to control the crankshaft's end play, which is the amount of fore-and-aft movement it can have within the engine block. This prevents the crankshaft from shifting too much and causing damage.

Do I need to replace these during a standard oil change?

No, thrust washers are internal engine components. They are typically replaced only when the engine is disassembled for a rebuild or major repair, such as replacing connecting rod bearings or the crankshaft itself.

What does 'end play' mean for a crankshaft?

End play refers to the axial or fore-and-aft movement of the crankshaft within the engine. There's a small, acceptable amount of play designed into the system. Thrust washers help keep this movement within the manufacturer's specified limits.

About this part

Product Details

If you're rebuilding the bottom end of your 2002-2013 Nissan Altima, Frontier, Rogue, or Sentra with the 2.5L QR25DE engine, a new thrust washer set is a critical component. These washers sit between the crankshaft and the connecting rod journals, controlling the crankshaft's end play. Proper end play is vital to prevent the crankshaft from moving too far forward or backward within the engine block, which could lead to serious damage.

This set from Clevite is made to meet the original specifications for your engine. They are well-built to handle the pressures and friction they encounter. Installing new thrust washers is a standard part of a thorough engine rebuild, ensuring the crankshaft operates within its designed tolerances. It's a small part that plays a big role in the overall health and longevity of your engine.
