Topic: 1935 Flathead Water Pumps

  Hi. I am new to the forum - thanks for the opportunity.
I have a 1935 Model 48 with the 32-36 style water pumps. The driver's side pump is spitting water from behind the pulley.
I am considering whether I rebuild myself, have a rebuild done, or buy rebuilt pumps. I've been wrenching on cars for years and do my own work, so DIY would be an option.
What is the recommended path? Are there any pitfalls or good guides to working on these pumps?
Many thanks.

  Can't help you about DIY for water pumps but here are two excellent rebuilders. I have personally used Skip and very happy with his work.]

  If you are not worried about originality for a point judged show car, the simplest thing to do might be to go with these pumps which utilize new castings, improved bearings and seals. They are offered by both C&G and Dennis Carpenter.

  Most of these pumps have been rebuilt a 100 times over the years. The gap between the impeller and the casting needs to be tight something like .010 as I recall. You could throw a cat through the gap on a lot of the old pumps. They may not leak, but they don't pump water very well.
Save yourself a lot of grief, buy a new pair of pumps. Dennis Carpenter, Fryers, Skip Haney and others handle them.

  I bought some new water pumps from Dennis Carpenter several years ago for a 1953 Ford V-8. These pumps proved to be problem-free over 15K miles of service. I would recommend them if you intend to drive your car trouble-free over long distances.
