Professional Installation Protocol
Flywheel Preparation & Friction Surface
Do not install fresh friction hardware on a glazed, grooved, or heat-checked flywheel surface. Flywheels must be precision resurfaced or completely replaced to ensure an optimal mating profile. Thoroughly clean the pressure plate surface and flywheel face with raw brake cleaner to strip away anti-rust shipping oils.
Any remaining oil residue will cause immediate clutch chatter and catastrophic friction glazing.
Pilot Bearing & Concentric Alignment
Install the fresh replacement pilot bearing or bushing into the crankshaft bore cavity. Leverage a dedicated spline alignment tool to hold the friction disc perfectly concentric relative to the pilot hub before locking down fasteners.
If the disc shifts even slightly off-center, you will deform the hub splines or bind the transmission input shaft during bellhousing mating.
Torque Sequence & Fasteners
Position the pressure plate square over the alignment tool guide. Hand-start all retaining bolts to eliminate cross-threading damage to original threads. Torque all fasteners to the manufacturer’s exact specifications.
Fasteners must be torqued in a progressive star pattern spanning three distinct incremental stages to prevent cover warping.
Release Fork Geometry & Hub Pre-Lube
Thoroughly inspect the release fork linkage and mechanical pivot ball for structural wear or pocket pitting. Lightly coat the inner sleeve groove of the release bearing and the input shaft snout with a premium, high-temperature clutch grease.
Do not over-lubricate; excessive grease will sling outward onto the friction faces under load, resulting in catastrophic clutch slip.
