The faulty unit (secondary gear / torque clutch)371 viewsShowing the inadequate circlip retaining land, ripped iopen by the normal spring tension. Should never have been made of plastic...
|
|
Gear box casing showing wear from screaming friction...407 views...once the circlip has bust through the inadequate retaining land, the spring presses on the (other) gearbox casing, forcing the secondary gear to wear on the gear box casing where shown, there being no adequate provision for end-thrust (even though helical gearing would mandate that, to cope with the NORMAL axial vector forces produced) resulting from spring pressure on the other gearbox casing face pushing the gear into this face.
