  • The Suzuki G13A, G13B, G13BA and G13BB engines

    The G13BA (8-valve) and the G13BB (16-valve) are Suzuki's 1.3 litre four-cylinder engines; they power the Samurai, Sierra, Jimny, Swift, Baleno and Carry, among others. ACL lists a single bearing set for the G13BA and G13BB.

    From the factory, this engine is fitted with standard production connecting rod bearings, sized for the loads of the original engine: as soon as power, engine speed or boost pressure increase, they reach their limits.

    Trimetal connecting rod bearings

    A trimetal 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 8 half shells, four pairs for a four-cylinder engine.

    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.

    Size / gradeWhen to choose itACL Race Series
    Standard (STD)Standard journal, not reground0.047 to 0.055 mm
    Increased clearance (HX)Wider clearance: high oil flow, high rpm0.072 to 0.080 mm
    +0.25 mmJournal reground to 0.25 mm0.047 to 0.055 mm
    +0.50 mmJournal reground to 0.50 mm0.047 to 0.055 mm

    Checking on assembly: lay a calibrated strip (Plastigauge) on the journal, torque the rod cap to spec, then compare the crushed strip against the gauge to read the clearance.

    Technical guide

    The ACL rod 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 brand

    ACL Bearing CompanyACL Bearing Company, an Australian manufacturer of high-performance engine bearings since 1949, offers with its Race Series precise trimetal bearings, available in many sizes and proven on built engines worldwide.
