Oil pressure check

Whenassemblyoperationsarecompletedllenginewithoilandfuel;

connecta10barpressuregaugetotheoilltertting.

Starttheengineandcheckpressureasafunctionoftheoiltempera-

Calibrated pipe for lubrication of hydraulic tappets

The pipe is tted to the hydraulic tappets oil line (see g. 83, detail

11).

If the calibrated hole is clogged, the tappets are not sufciently

lubricated,valveclearanceisthereforeincreasedandtheenginemay

benoisier.

Ifthediameterofthecalibratedpipe islargerthantheones givenin

picture93,thepressureexertedby the hydraulic tappetsmaycause

thevalvestoremainopenevenduringthecompressionphase.
