MCS, Tappet Block/Oil Pump Alignment Screws for Harley Davidson

They are used to align the oil pump with the cam support plate on Twin Cams.
They help reduce oil pump scavenging inefficiency due to oil pump misalignment.
They are also used to align the tappet blocks on the L76-99 BT models so that the lifters rotate correctly on the camshaft.
Thread size 1/4"-20. Two alignment screws are used.

Fits: > Oil Pump: Twin Cam 99-17 ; Tappet Blocks: L76-99 BT (excl. Twin Cam)
