Professional Engine Assembly
All of the assembly cleaned engine components are laid out and organized in our clean assembly room. Our Professional engine assembly insures top builder confidence because we triple check all clearances, gaps, torque specifications, and settings. All of the bearing clearances are final checked and confirmed.
Connecting rods and pistons are assembled and wrist pins are lubed with our moly-based lubricant. Piston ring gap is measured, checked and file fit to the specific needed tolerance. The ring file procedure takes place in the machine room and not in the assembly room. Then we install the piston rings onto the pistons.
The camshaft is lubed with our high-pressure moly-based high zinc cam lobe grease and the cam bearings are pre-lubed with bearing lubricant and the camshaft is carefully installed into the engine block.
We lay the main bearings into the block and main caps in the correct order and we pre-seal and install the rear main seal into the block seal housing. The rear main seal and bearings are lubricated with bearing guard. Then the crankshaft is installed into the block, the main caps are installed into place, the main cap fasteners are installed and lubricated with bolt lubricant so correct fastener torque will be achieved. Crankshaft thrust is set and indicated. Then the main caps are torqued in sequence in our specific order. Main bearing cap torque is checked three times.
The timing components are installed, cam fastener is torqued and the cam thrust is set. Piston wrist pins are properly and thoroughly lubricated with our high pressure moly lubricant. The rod bearings are installed into the connecting rods and lubed with our bearing guard. Number one piston assembly is installed into the engine block. Camshaft is degreed, documented and set. Valve to piston clearance is checked, documented and set. Rocker arm geometry is checked, set and confirmed. Absolute pushrod length is determined. Remaining pistons and rod assemblies are then installed into the engine block using our proven cylinder lube to insure positive ring seal. The connecting rod fasteners are lubricated and torqued using the correct sequence indicated by the fastener manufacturer. Final torque is checked three times.
Rotating rod clearances checked and confirmed. Oil pump is installed and pre-lubed for quick priming and the oil pump pick up tube is installed. Sump depth checked and tube height adjusted for correct oil sump depth point. Front cover and oil pan are sealed, installed and torqued.
The harmonic balancer is installed and true top dead center is confirmed and re-marked if needed. This is critical to set absolute ignition timing. The block deck and head surfaced get final wiped clean of any contamination. The head gaskets are correctly installed into place. The cylinder heads are installed and the head fasteners are appropriately lubricated with the correct compound for the engine. We then start the cylinder head torqueing procedure done in proper fashion and correct sequence.
The valve train is then installed with proper lubrication. The correct valve adjustment is set and checked three times. Intake manifold is checked for absolute indicated angle correct to the engine head angles. Port alignment is checked. If applicable intake manifold is milled for proper angle correction and for correct positive port alignment, this will insure the intake is matched perfect with the engine for a perfect fit and seal. Cleaned intake is sealed, installed and intake fasteners are appropriately torqued. Other engine components are installed if applicable.
Finally the engine will be moved to our Dyno Room or wrapped if completed to our customers desire.
