Is there a supplier of V belt type pulleys that fit the Model T? Looking for one that will install on the crankshaft that will accept two belts. 1 belt to run fan and another to run water pump and aftermarket generator. I NEED to be different or is it difficult? Thanks for your input in advance.
The suppliers (Snyders is one), used to offer a v-belt conversion set of pulleys, consisting of a crank, fan and water pump pulley. Don't know if they still do and don't know of anyone who offers a multiple sheave pulley set (for multiple belts). With resourcefulness, you should be able to make something work, as there have been Model T owners who have even run air conditioning compressors off belts to air condition their T's.
You didn't specify a year, but I'm guessing pre-19 as 19-27 Fords with starters have a generator that needs no belt. Rather than install a generator, with its attendant alterations, why not use a magneto battery charger? It's quite simple and has no moving parts to deal with. The water pump is superfluous on a Model T in good condition (the car came without it), but if you want to use one you can run it with a normal Model T belt.
I have used a flat serpentine belt inside out for the last ten years with no problem.
I have them in kit form and have been using them with excellent results on my Speedsters from hell. firstname.lastname@example.org
This will be on a 26/27 two seat speedster that I am building from scratch (fiberglass roadster fun with hand built boat tail). I was planning on installing a dry sump oil pump where the original generator is mounted.
Snyder's still offers the V-belt setup. It's part #T-3965 and fits 1920-1925.
Kim I have the complete set up you are talking about, PM me and I will send pictures, it is still on the car. I was going to remove and sell. Thanks Sam
Here's how I used a serpentine belt to run the alternator and the ac compressor on my 25 Fordor. The ribs on the belt are starting to make shallow grooves in the aluminum cs pulley. The belt is about 1 inch wide and just tight enough so nothing slips. It works great. Just another idea 4 U. (I have an oil pump in the normal generator spot.)
Hal, any close up of your idler set up?
Kim, I found one. That back side idler is made of two idler bearings.
Error correction: It's the fan pulley where the grooves are slightly wearing. The crank pulley is a grooved pulley from one of the vendors.
Thanks for all the ideas folks.
