Abstract
Abstract A pilot ring assembly is provided for locating various power driven apparatus with respect to a power source housing such as an engine or motor. The ring assembly obviates having to machine locator steps of various diameters in flanges on the engine block or motor housing. This is effected by machining locator steps in flanges at a predetermined position and then placing pilot rings of varying outside diameters to accommodate the locator rings of the power driven apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A pilot ring assembly for locating various power driven apparatus to a power source comprising: a power source housing having an opening for a power take off shaft; flanges connected to the housing and surrounding the opening; a locator step positioned in the flanges, the locator step in each flanges aligned in a circular manner around the opening; and a pilot ring connected to the flanges and abutting against the locator step at its inner diameter and abutting against a locator ring of a power driven apparatus at its outer diameter.
Claim 2
Dependent Claim
91 words
A pilot ring assembly for locating various power driven apparatus to a power source comprising: a power source housing having an opening for a power take off shaft; flanges connected to the housing and surrounding the opening; a locator step positioned in the flanges, the locator step in each flanges aligned in a circular manner around the opening; and a pilot ring connected to the flanges and abutting against the locator step at its inner diameter and abutting against a locator ring of a power driven apparatus at its outer diameter.
Claim 3
Dependent Claim
20 words
