Tech InformationInstallation Tips

	1. Check all connecting rod housing bores for taper, roundness and size by using a bore gauge or inside micro-meter. Check for parallelism between the large and small ends of the rod. Check conditions of bolts and threads.
	2. Check main bearing bores for alignment, taper, roundness and size. Check conditions of bolts and threads.
	3. Make sure that engine block and crankshaft are clean by checking oil passageways for hidden dirt and debris. Hot water and detergent work best for cleaning.
	4. While installing both connecting rod bearings and main bearings, check for proper oil clearance with Plastigage®. (Part #MPG-1, .001" -.003"; #MPR-1 .002"-.006";#MPB-1, .004"-.009"; #MPY-1, .009"-.020")
	5. With the engine block upside down, install the upper main halves making sure bearing backs and bores are clean and dry.
	6. Check oil hole alignment to insure proper oil flow.
	7. Lubricate all bearings and seal lip surfaces using Clevite 77® Bearing Guard. (Part #2800B2 - 8 oz. bottle, #2800B - 1 gallon jug, and #2800B5 - 1 1/3 Oz. package) Use Clevite® Cam Guard (Part 3CL 400), EP rated lubricant on camshaft lobe and lifter faces.
	8. Place the crankshaft squarely into the main bearings and assemble lower main bearings and caps. Check to insure proper position.
	9. Pry crankshaft toward the front of the engine to align thrust faces. Torque main bearing bolts to proper OE specifications. Rotate the crankshaft by hand to see that it turns freely.
	10. Assemble the connecting rod and piston assembly to the crankshaft by using Clevite 77 Bolt Boots (Part #2800B1) to protect crankshaft journals and cylinder walls. Make sure caps match correct rods, and torque bolts to proper OE specification.
	11. With the crankshaft forced all the way forward in the block, check end clearance between the crankshaft thrust face and the bearing flange to OE specification. Use a feeler gauge for proper thickness.
	12. Prime engine oiling system before starting engine to assure operation of oil pump and lubricating system immediately upon start-up.

Unlike many engine bearings available today, Clevite 77® engine bearings utilize a superior Clevite 77® Tri-Metal™ material design. Stamped "Clevite 77" this design incorporates the strength of a copper-lead alloy layer on a steel back and a precision electroplated white metal "babbitt" third layer. Tri-Metal is an ideal bearing design producing good to excellent characteristics when judged for conformability, embedability, slipperiness and fatigue resistance.

We constantly monitor the function and operation of our full line of bearings by staying in touch with any changes or developments that new engines may require. That translates into bearings that are better for your engine. If you're looking for the engine bearings that set the standards, specify Clevite 77 –ecause you won't settle for second best.
