Refitting ScatHigh Lift Rockers

19th April 2013
My beach buggy had been in storage most of the winter due to the rubbish weather and constant rain that we were having in England This had put even Mother nature back 21 days. My first outings in the buggy in the new sunshine where short and under powered. I wondered if this was my caliper sticking issue returning  or if the valve clearances just needed re-setting. I decided that as I had to re set the valve clearances it would be a good idea to put my High lift Rockers as these gave the car a much more interesting sound when it was ticking over. I located the Valves in my storage unit and checked them over they seemed to be in good condition . I noticed that 1 of the .60mm shims was missing. I spent a lot of time looking for the spare shim only to find later that it was stuck to one of the others.

Setting up the rockers has already been covered in a previous section on this blog . I will not cover this again and assume you have read this. My Rocker covers where the bolt on type and were held on with two 13mm bolts. Once thse was removed the 1.2 rockers where visable and could easily be unbolted. Whilst I had the rocker covers of I decided that they was in desperate need of a clean up.

I knew the high lift rockers would need shimming as the previous installation used two roker shims  After starting with .60mm which  presumed  would be a good starting point to work from. This meant placing two new rubber seals on the rocker shafts and then placing on one greased shim on each shaft. The rocker was then placed onto the shafts , whilst aligning the push rods into the rockers cups. This can be a little tricky but can be achieved by holding the rocker in place and gently moving the rods into their respective cups. The rockers where then bolted to the  head using a torque gauge set to 18 lbs/ft or 2.5 KG/m. Once these was firmly bolted the car was left a couple of hours to let the temperature of the parts become the same. I took my covers away at this point and started to clean them up. When I looked further this was just not rust just a coating that was on the .Once I had  assembled the rockers I  adjusted the tappets and took the buggy out for a run.
