Tensioner Holding Pin Assist Tool
This tool is used in conjunction with a double box wrench. By flexting the accessory belt tensioner (with my Spacer Tool mounted) and installing this pin as shown gives access to the one timing chain cover screw that's blocked by the tensioner (highlighted in red circle).
Allows a single technician to do this instead of a helper.
Tool is made from a M8 Tripple Square bolt with a machined brass sleeve.
