Introduction
This instruction sheet provides guidance on installing hydraulic tappets (valve lifters) in an engine and measuring the pre-load on the push rods.
Purpose
The purpose of this instruction is to ensure correct installation of hydraulic tappets and to measure the pre-load on the push rods, which can affect engine performance and cause noise.
Pre-Checks and Procedure
Before installing the hydraulic tappets, the engine must be prepared by flushing, replacing the oil filter, and checking the camshaft for wear. The instruction then guides the user through the installation and measurement process.
Interpretation of Results
The measurement results will indicate whether the pre-load on the push rods is excessive, which can cause noise from the valve lifters. If excessive pre-load is found, the instruction provides guidance on how to resolve the issue.
