Power Piston

(1/1)

Paul:
is there a concern how much side to side play is between the power piston and guide,  power piston in the bore? I know vacume makes the piston move, but if there is too much side to side play, would this cause a vacume leak? the piston moves up and down freely, just worried it may be too much.

Cliff Ruggles:
Not really an area of concern.  I've never found any measurable wear on a power piston or the bore.  Helps to install a new plastic retainer with a good fit at the top of the bore.  All of our kits come with a new power piston retainer.....Cliff
