We require a good synchronizing tool for these distributors, for use in service, can you recommend one suitable for our use? We have had no further breaking of the contact lever pads since we changed to the thicker pad, however, we have had one car, in which the rate of wear was criticised, we are carrying out tests to prove this, at the moment we consider this due to lack of lubrication.
