Cam follower - Improved with oil slots
The original design and manufacture of XPAG cam followers back in the 1930’s was very poor.
They did not allow enough oil to flow on to the base of the cam follower and camshaft lobe. This lead to increased ware of both the cam follower and camshaft.
The cam followers on the market today are unfortunately made to the same design – So if you buy them you will still have the same problems.
However.... Our cam followers are modified with four slots to allow a constant flow of oil to the cam follower base.
