Speedometer 407
Late last year I had my Speedometer reconditioned by Speedograph Richfield and I replaced the cable.
Everything has seemed OK after the rebuild but with winter and lockdown I have done very little mileage. On the Layer Marney Tower Cup run last weekend the speedo packed up again, it was removed today and this time the cable is intact and the trip is OK but there is a plastic box behind the speedometer marked HUNTER , the maker perhaps, the speedo cable enters this box and then the speedo, I presume it is some sort of reduction gear inside the box. It is pretty mangled in the connecting female hole. The speedo head it tight to turn and I feel this has lead this time to the reduction HUNTER box being rendered useless. Please can anybody help with an explanation as to the function of the box and any idea about where I may obtain a replacement. Thank you in anticipation, Nick.
