Kolbenschmidt 77813600 — Crankshaft Main Bearing Set
Overview
Main crankshaft bearing set Kolbenschmidt 77813600 locates the crankshaft main journals inside the engine block cylinder housing and reduces friction during engine rotation. Manufactured in standard size STD for housing bore diameter 59.00 mm and journal diameter 54.00 mm. Each shell features width 18.5 mm and wall thickness 2.48 mm. Constructed with steel backing and aluminium-tin anti-friction lining, these components withstand alternating mechanical loads and oil starvation during cold start. The set includes lubricated main shells with oil grooves and supply holes for continuous oil flow under pressure. OEM cross-references include VAG 06A105561A, 06A105591A, 026105561A, and 038105561A. Supplied as a complete engine overhaul set for petrol and diesel engine rebuilds.
Fitment includes Audi A3 8L/8P, A4 B5/B6/B7, A6 C5, Volkswagen Golf IV/V, Passat B5/B6, Polo 9N, Touran 1T, Skoda Octavia A4/A5, Fabia 6Y/5J, Seat Leon 1M/1P, and Ibiza 6L/6J fitted with 1.6, 1.8T, 2.0 petrol or 1.9 TDI and 2.0 TDI diesel engines manufactured between 1996 and 2010. Replacement is required when encountering deep scoring on shell surfaces, low oil pressure readings, metallic knocking noises from the lower block, or during complete engine overhaul procedures. Severe lining wear leads to shell spun bearings, housing bore scoring, and catastrophic crankshaft seizure. Installing fresh bearings restores original oil clearance to 0.02–0.06 mm and maintains oil film pressure across main journal surfaces under all engine operating conditions.
