Topic: WATER PUMP IDENTIFICATION

  I just removed the passenger side water pump from my '36 and wonder if it is the proper one for the car? It is stamped 40-8505-6 and has a brass fitting that appears to protect a grease fitting. Is it actually a '35 late pump?
Thanks.

  The number you have appears to be a 1934 pump. The 36 will have a 68 prefix instead of 40. If you need one I can probably help you. The pump will also work fine but for judging purposes you would want the 68 # Hope this helps.

  35ford is correct. Also the brass cap covering the lubrication fitting is not correct for 36. 36 used Zerk fittings on a special steel adaptor. This fitting and the angle of the casting in the pump allowed room for the Zerk to have a grease gun attachment without touching the pulley. The diagram below is from Don Rogers. It shows one of the different styles of the lubrication and Zerk fitting. Suggest you look in the club 35-36 restoration book where this is covered. The book is available on this web site.

  Rogbell, 40-8505 is the housing number for a 40-8503 Right Hand water pump used on 1935 and early 1936 production (thru 4/36) vehicles. If your 36 is early, then it is possible that it is the original pump.

Note: The 68-8503 (introduced in 1/14/36) replaced the 40-8505, but the transition wasn't complete till 4/36
