Cleaning: All components chemical cleaned, paint removed and descaled back to bare metal.
Cylinders: Rebore & hone cylinder bores, resurface top deck, re-tap all threaded block holes.
Crankshaft: Visual inspection, re-tap flywheel bolt holes, “NDT” crack test,
measure journals, polish or regrind as necessary.
Conrods: Visual inspection, check & replace small end as required, measure big end bore and proof hone or resize as required. Check for bend and twist.
Gears: Visual inspect fuel cam, valve cam, gears & governor parts. Replace
parts if required. Cam followers re-faced.
New parts fitted: Pistons, rings, main bearings, conrod bearings, crank – thrust
washers, core plugs.
Assembly Fit up conrod and main bearings prior to assembly and check running
clearances, measure piston to bore clearances, measure ring gaps. Fit core plugs to block, paint block, fit crankshaft assembly to block, fit piston & conrod assemblies to block, fit fuel & valve cams – gear train, measure and adjust piston heights as required.
