    Default D Tappet Clearances : Automatic Gear Box

    I trust that this query is appropriate herein.

    I've taken the Radiator Overflow Tank off to refurbish it and clean the the Rocker Cover up a bit whilst working on the Fuel Injection System (replacing all hoses). With rocker cover off, I'd like to check valve clearances.after

    How does one rotate the D motor coupled to an automatic gear box. I do not want to buy / chase up a 6 volt battery.

    Whilst not advisable, is it possible to rotate via the camshaft pulley upon removal of spark plugs. I do believe it is [and would not dare try it] but curious what other have done / do.

    Regards,

    John

    Hi John, the camshaft method is perfectly OK if one removes the spark plugs first! Then only turn the cam shaft in the tightening direction of the pulley nut!

    Thanks Gerry for the confirmation that it can be / has been done before. And yes, essential to rotate in the direction that the motor rotates.

    No, not inept Peter, just not applicable in this case.

    Notwithstanding that "my" previous vehicles had the gearbox behind the motor and if I did not have access to the crankshaft pulley, I was able to rotate the motor by pushing the vehicle in gear as they had manual gear boxes. I did not consider lifting one wheel! I will in the future as I'm past pushing vehicles. [It would not work with an LSD though].

    So, very competent advice as far as I'm concerned but not appropriate in this case.

    Thank you.

    Just a top on the spark plug seals
    By putting a small diameter O ring on top of the existing large one a perfect deal is obtained
    About 1-1.5 mm is fine
    Cost $1 from Bursons

    Thanks Sherman, I will consider provided that the "seal" between rocker cover and head is not compromised as I do not propose to use a new seal (looks / feels pretty usable).
