Lynx II, hull # 4225

[Andrew Rowe]

Hi Peter, I see you making good progress. The tag is the standard diff identification tag. C29SR , I think this means 1942, scout car , rear engined.
The 4000 B is the part number for the diff. In this case 6.66 to 1 ratio.
Has 640 stamped on the back of the housing, which means 6 teeth pinion and 40 crown wheel . Outside dia. of diff housing will be 14 -7/8'' across. This assembly supplied for service from serial #3000.
The front diff will be tagged 3000 C , if the tag is still there. The gen pulley you are going to swap over, just be careful it is not screwed onto the shaft, some are some are just keyed on, a trap for young
players is to put a puller on a screwed on pulley and smash it to bits, I know I have done it!
