PLEASE READ THE FOLLOWING GUIDELINES THOROUGHLY

  • The chain should not be shortened.
  • Using a new chain is recommended, especially if your engine has done more than 200000km.
  • You will need to reuse the bearing from your stock pump gear.
  • When removing the bearing from your stock pump gear, do it as gently as possible, a press tool is highly recommended. (The bearing is very soft and hitting it affects the next point a lot)
  • Make sure the upgrade pump gear spins without resistance on the centerpiece before mounting. If not, a slight hone might be necessary. Use oil when fitting centerpiece.
  • Make sure the gear spins properly when you have tightened the bolt.
  • remove washer from chain tightener, use sealant or replace with narrowest possible washer to prevent leaking.
