Hello
In February this year noticed a major engine rattle in my machine. After removal of the rocker cover found up to .040" of play in the rear exhaust valve, this in turn lead to an examination of the camchest area. After removal of chest cover,inspection revealed 3 of the 4 inner bushings had loosened in the crankcases and spun causing damage to crankcase (ovalation). There is scarring on the cam lobes and also on the pinion shaft on the crank. There is also damage to the outer bushing of the pinion shaft. The oil level was as always correct.
Am I correct in assuming that this engine is now total scrap or is there any cost effective way to repair it?? Does anyone know who can repair and any indication of cost etc??
I should point out that i have spoken to
about this issue briefly some time ago,before I carried out the inspection, and he pretty much diagnosed the problem over the phone (how good is that!! lol) Basically the inspection confirmed my worst fears. The machine was first registered in 2008 and had a complete rebuild under warranty in march 2009 due to big end failure. Thanks
