Piston, Installing

WARNING: This page is about a different car, the 2008 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required

Piston insertion funnel T10147

NOTE:

If a new T10147 is used to install the pistons, first pass the piston with lubricated piston rings through the funnel twice and remove the resulting metal shavings if necessary. Only then install the piston with rings.

Procedure

-- Push the piston by hand into the lubricated T10147. The flat side of the piston crown must face toward the funnel pin -arrow-.
