Sidgreaves - MD}'s Wraith has been into Cricklewood for a knock in the rear of chassis. This was traced to the O.S. rear damper having .009" lateral play in the rocker shaft, causing a metalic knock. This was reduced to .002 - .003" which cured the knock complained of. GWH.{George W. Hancock - Head Chateauroux} | ||
