Based on the provided reference, adjustable push rods come in a range of base lengths from 5.800 to 10.800-inch.
Push rods are critical components in overhead valve (OHV) engines, transmitting the movement of the camshaft lobe (via the lifter) to the rocker arm, which in turn opens and closes the valves. Their length is crucial for proper valve train geometry and operation. The reference focuses on a specific type: adjustable push rods.
Base Length Range
According to the information provided, adjustable push rods are available in a selection of base lengths falling within a specific range. The reference states:
The adjustable pushrods come in five separate lengths from 5.800 to 10.800-inch.
This indicates that while there are specific, discrete lengths offered, they are all found between the 5.800-inch and 10.800-inch marks.
The Impact of Travel
A key feature of these adjustable push rods is their capacity for travel, allowing them to extend beyond their base length.
Each pushrod will offer one inch of travel.
This means the effective length of the push rod can be extended by up to one full inch from its specified base length.
Example:
As illustrated in the reference:
For example, the 10.800-inch version pushrod tool will extend out to 11.800 inches.
This demonstrates how the one inch of travel is added to the base length to determine the maximum possible extended length.
Summary of Lengths
Considering both the base length range and the travel feature, the lengths associated with these adjustable push rods can be summarized as follows:
| Aspect | Length Range (inches) |
|---|---|
| Base Length | 5.800 - 10.800 |
| Max Extended | 6.800 - 11.800 |
Note: The "Max Extended" length is the base length plus the 1 inch of travel.
In essence, while their base size is set within the 5.800 to 10.800-inch range, these adjustable push rods offer flexibility by allowing their length to be increased by up to one inch through their travel mechanism.
