The Straight Tube is used to measure the presence of maintenance free oil filled linkage pins during service activities. The tube fits into the internal passage of the linkage pin to allow accurate air space measurement. It supports determining whether the correct oil level is maintained inside the pin. Controlled insertion allows clear detection of trapped air without disturbing internal conditions. Accurate air void measurement helps identify improper filling conditions during maintenance checks. Using this tube supports reliable inspection results and consistent evaluation of the internal linkage pin condition.Attributes:• Supports accurate inspection of internal oil volume.• Allows controlled insertion into linkage pin passages.• Helps identify trapped air during maintenance checks.Applications: The Straight Tube is located within oil filled linkage pins during service checks, where it measures trapped air void levels to confirm proper oil fill and internal condition status.
