149 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, fortunately both times it was with 4-71 engines and not 149's! But, be warned - be careful!
Suggestion - Apply locktite (or equivalent thread lock compound) to the 1/2 NF bolts
STEP 1 -- torque to 35-45 lb-ft, 47-61 Nm
STEP 2 -- turn extra 60° to 80°

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.
