| Bolts and washers ?
A friend of mine in the UK, a cobra replica manufacturer, has just reported than one of his customer built cars has failed the SVA (Single vehicle approval) inspection and therefore has failed to get a registration. The reason for the refusal was that the rear cover on the differential housing was assembled with both a plain and a spring washer under the bolt head ! The inspectors attitude was that the bolt could loosen because the plain washer would allow the fastener to rotate. What is your view ? Do you think the tang on the spring washer is the locking mechanism, or do you think the tension imparted by the spring locks the bolt ? Frank |
