Product Overview
MB6224 is an unflanged conrod main bearing set intended for use in K14B petrol engines fitted to selected Suzuki and Toyota models listed above. Correct bearing selection and installation are critical for oil film integrity, crankshaft support and long term engine reliability. When matched to the correct journal size and installed by a qualified workshop, these bearings can form part of a comprehensive engine refresh or rebuild for everyday South African driving conditions.
The focus during installation should be on accurate measurement, clean assembly practice and correct lubrication. This helps reduce the risk of premature wear, noise or failure and supports customer confidence in the repair work carried out.
Fitment Guidance
- Identify the engine as a K14B 1372 cc petrol unit and confirm that the vehicle model and year range match the applications listed.
- Measure crankshaft main and conrod journals with calibrated micrometers to determine whether standard or undersize bearings are required.
- Confirm that journal roundness and taper are within acceptable limits for the chosen bearing size.
- Ensure all oil galleries and crankshaft drillings are thoroughly cleaned before assembly.
- Lay components out in a clean environment and avoid contact with dust, dirt or metal shavings.
Installation and Maintenance Tips
- Use proper engine assembly lube or clean engine oil on bearing surfaces during assembly to prevent dry start conditions.
- Align bearing locating tabs correctly in the block and conrod caps according to engine design.
- Torque main and rod bolts to the correct specifications using a calibrated torque wrench, following the sequence in the workshop manual.
- Rotate the crankshaft by hand after each stage of assembly to confirm that it turns freely without binding.
- Prime the lubrication system before first start where possible and monitor oil pressure on initial run in.
- After installation, avoid extended high load operation until the engine has been run in under controlled conditions.
Important Installation and Returns Warnings
⚠️ Engine Parts Installation Warning
Important: Engine components such as bearings, pistons, rings, valves, gaskets, and related parts must be installed only by a qualified, VAT-registered workshop using proper measuring and torque equipment. Ensure crankshaft journals are measured and polished, oil clearances verified, and assembly lube applied. Failures due to oil starvation, contamination, incorrect sizing, or improper torque are not manufacturing defects and are not covered under warranty. Always replace engine oil, filters, and gaskets during installation.
