  • The VAG VR6 engines: 2.8, 2.9, 3.2 and 3.6 (R32, R36)

    The VR6 is a narrow-angle V6 used by Volkswagen, Audi, Seat and Ford. It spans the 2.8 and 2.9 litre engines of the Golf III and Corrado (AAA, ABV), the 3.2 litre engines of the Golf R32, Audi TT, Audi A3 and Touareg, up to the 3.6 litre engines of the Passat R36 and CC (BWS, BLV). All of them share the same crankshaft journal and housing dimensions: a single bearing set covers the whole family.

    The crankshaft of these engines runs on seven main bearings. Each journal turns between two half shells, one seated in the block and the other in the main bearing cap: they carry the crankshaft. The ACL Race Series and KING RACING tri-metal sets shown here replace them on built engines.

    Tri-metal main bearings

    A tri-metal bearing stacks three layers: a steel back, a copper-lead intermediate layer with high load capacity and an anti-friction running surface that protects the journal. The complete set contains 14 half shells, seven pairs for seven main bearings. The upper and lower half shells are different: each goes in its own position.

    An aluminium bi-metal takes around 8,000 psi, a performance tri-metal up to 12,000 psi, 50% more. Hence better resistance and better durability on turbocharged, supercharged and high-revving engines.

    Running clearance

    The running clearance is the gap between the bearing and the journal where the oil film flows.

    In operation, the crankshaft journal does not rub against the bearing: it rides on this oil film, which carries the load. Clearance sets the thickness of this film: too tight, oil flows poorly, temperature rises and the risk of seizure increases; too loose, oil escapes, the film loses load-carrying capacity and oil pressure drops. The right clearance is the balance between adequate lubrication and a well-maintained oil film.

    Check at assembly: lay a calibrated strip (Plastigauge) on the journal, tighten the main cap following the manufacturer's procedure, then compare the width of the crushed strip with the gauge to read the clearance.

    Technical guide

    The ACL and King main bearings shown here are trimetal bearings, designed for engine building and racing. Compared with an original bearing, they handle far higher loads: they cope with increased power, high rpm or the addition of a turbo or supercharger, where a standard bearing quickly reaches its limit.

    The two brands

    ACLACL Bearing Company, an Australian manufacturer of high-performance engine bearings since 1949, offers with its Race Series precise tri-metal bearings, available in many sizes and proven on built engines worldwide.
    King RacingKing Engine Bearings, an Israeli manufacturer of high-performance engine bearings since the 1960s, offers with its pMax Black tri-metal alloy bearings designed for heavy loads.
