It is imperative that engines in service be shut down and the work done as soon as you can obtain the new cooling jets. : Do not attempt to bend a tube as this can crack the brazed joint, or cause interference with the crankshaft or connecting rod. If a piston fails before new cooling jets can be installed, measure clearance on the other pistons while still installed. If less than in Step 1 below, install a new 4N9881 Tube Assembly. Install complete set of new pistons regardless of clearance found. Some OEM's now offer a truck with a set-back front axle. The special oil pan used has a plate between the block and pan. Remove the oil pan and then the additional bolts that hold the plate. : This plate is heavy - use care when it is removed. It weighs about 31 kg (68 lb). 1. After installing the new cooling jets, measure the piston-to-tube clearance. Use a wire of known diameter. Minimum allowable clearance is 0.64 mm (0.025"). 2. Stamp "U8" in the Modification Block on the engine serial number plate on the block. 3. Send in a SIMS report on the completion of the PIP, using PI3096 as "Part Number" and 7751 as "Group Number". Also: Inspect all engines recently rebuilt in which the listed new pistons have been installed if you believe the replacement pistons were shipped from Morton after the "suspect" shipping
