IMPORTANT INSTALLATION NOTES
For LS7 or LS3 Dry Sump Engines that do not already have a GM LS9 Crank Sprocket, you MUST USE a GM LS9 Crank Sprocket (GM Part #12622539) for proper installation of the Katech TrackFlow™ LS7 & LS3 Billet High-Capacity Scavenge Oil Pump. Failure to change the crank sprocket will result in oil pump binding and WILL NOT BE COVERED UNDER WARRANTY.
TIMING CHAIN TENSIONER AND CLEARANCE REQUIREMENTS
The Katech TrackFlow LS7 & LS3 Billet High-Capacity Scavenge Dry Sump Oil Pump features increased scavenge stage capacity and a revised housing profile to support sustained high-load and endurance racing oil control. Due to this design, timing chain damper selection directly affects clearance with the oil pump body.
Approved Tensioner/Damper Configurations
The GM Gen IV LS2 Timing Chain Damper Kit (GMP-12588670) can be used only if the OE mounting bolts are replaced with shorter fasteners. The factory LS2 damper bolts may extend beyond the damper body and contact the oil pump housing, creating an interference condition.
Katech recommends verifying bolt depth and performing a trial fit during engine mock-up to confirm proper clearance between the tensioner assembly and pump body before final assembly.
