Today we jump to the Lynx speedo. I was looking at a post that Harry Moon was saying that he was going to look into his speedo situation, so thought I might put up a few technical bits of information with regards to the speedo.
Mk1 and Mk2 Lynx run the same speedo face. The drive gear originates from the transfer case and is cut on an opposite handed direction compared to the standard F15 single speed transfer case one. This is shown in the photo, the R/H one is standard F15 and L/H one is Lynx. As far as I can tell Mk1 and Mk2 use the same gear cut. The reason for this would be that the engine is mounted in the rear of the vehicle, so turning the transfer case in the opposite direction as opposed to the standard CMP truck with engine up front. The driven gear is a 15 tooth with part number 205052 , but is referenced as C19SR-17271 part number. The Mk2 Lynx uses a 16 tooth gear with part number 205039 , and is referenced by C29SR - 17271. The different gear ratio's come about because the MK1 uses a 5.83 differential ratio and the Mk2 uses a 6.66 ratio. Tire sizes on both model of Lynx' are the same, originally
9.20 x 16 , but today we just use the standard 9.00 x 16 , although I am thinking of using some NOS 1942 Dated 10.50 x 16 on my Mk2 , as the tires are in perfect condition, and they are runflats also. Cheers from The Tank Factory.
