These Tri-Metal 77 engine bearings combine the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal. The steel backing provides strength and durability; the babbitt overlay provides the critical surface characteristics of slipperiness and conformability. This ideal design has properties not even found in many original equipment bearings. Clevite offers main bearings, rod bearings and cam bearings in this series.

H Series -

Best to start with when unsure which bearing to choose

Medium level of eccentricity and high crush

Enlarged chamfers for greater crankshaft fillet clearance

Made without flash plating for better seating

Use with crankshafts that have oversized fillets

Use with engines that run mid-high RPM range

Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface

P Series -

Typically the greatest level of eccentricity

Rods and mains have high crush for maximum retention

Most are fully grooved to maximize oil flow to rod bearings

Reduced overlay thickness to prevent overlay fatigue

Use where extremely high RPMs cause severe rod bore close-in

Use where higher eccentricity is desired to narrow bearing contact patterns

V Series -

This series essentially duplicates Clevite's former Vandervell parts

Typically low to medium eccentricity

Not available with oversized chamfers

No flash plating on the steel back

All Clevite main bearing sets use a single-piece thrust bearing

Narrowed parts available to accommodate increased crankshaft fillet clearance

Lead-indium overlay offers slightly better conformability

M Series -

These are special purpose bearings having a nominal .005" thick Babbitt lining on a hardened steel back

They are intended mainly for Blown Fuel engines where severe crankshaft deflections cause edge loading of the bearings

Under these operating conditions bearing service life will be very short

Frequent inspection and replacement is recommended
