92 Series Pistons

On Cross-Head pistons - Torquing con rod to piston/gudgeon pin

Caution - Failure of piston pin retainer bolts is always catastrophic, often a hole in the block - it happened on two occasions to me while dyna-testing engines
Suggestion - Apply locktite (or equivalent thread lock compound) to the 7/16 NF bolts
torque to 60 lb-ft, 80 Nm; do not exceed torque

Installing piston/gudgeon pin retainer plates

Caution - Leaking retainer plates are only remedied by extensive rework, i.e. head and sump at least must be removed again.
Suggestion - Apply shellac (or equivalent compound) to rim of retainer plates
Rap retainer plate into place with a domed/rounded object of similar size to the plate. (small machined nylon rod is ideal)
Allow shellac to dry (overnight)
Test piston plate seal by pouring power-paraffin or diesel into the inverted piston, the outside of the plate must remain completely dry, let it stand for a few minutes before using it to make sure.

Now there are many exceptions to the above generalities. So check with your local agents and give them your injector type, with which they can provide you with the correct setting for your area and injector type. To reduce emissions consciously:- use the Californian settings.

If your air box pressures are close to the values listed in the table there is normally no problem in this area.
