Andrews Gauge Pin - 212105

Ensure precise cam gear measurements for your motorcycle engine builds and maintenance with the Andrews .105" gauge pins. This essential tool is specifically designed to accurately measure the outside diameter of cam drive gears, a critical step for optimal engine performance and longevity.

Description

The Andrews .105" gauge pins are a vital precision instrument for any motorcycle mechanic or enthusiast focused on accurate cam gear sizing. Understanding the nuances of cam gear dimensions is paramount, especially when dealing with different engine generations. These gauge pins help you navigate the specific differences between pre-'90 and '90-'99 cam gear sizes, where the overall range of measurements was reduced from .006" to .003" in 1990. While large gears for '84-'89 and '90-'99 (often color-coded green and black) are similar, the measurement methodology can vary significantly.

It's important to note that while some manuals might refer to measurements using .108" pins, these Andrews .105" gauge pins provide the correct baseline for earlier models. For the same gear, a measurement taken with .108" pins will appear approximately .012" larger than one taken with .105" pins, highlighting the need for the correct tool. Furthermore, for '92 engines, stock cam gears are interchangeable with earlier versions, but their outer diameters were reduced by .025". Manufactured with pride in the USA, these precision measurement pins are built to the highest standards, offering reliability and accuracy for critical engine work, including tasks related to Harley-Davidson cam gear specifications.
