I want to replace the grease nipples in my 32 model B. Can someone please tell me the size and thread type? How many straight and how many twisted do I need?
Most likely 1/8" NPT but don't know how many angled vs straight.
Are you driving your cabriolet around Gran Canaria? What a great island for touring. I spent some time over the years working with a pelargonium producer in Galdar. Loved it.
Assuming that your cabriolet isn't of very early production, there were only two angled grease fittings on '32 106" wheelbase chassis such as yours and those were on rear brake backing plates for the operating levers there. (It may be four if your mechanical brake system has four rear brake rods as did some of the European '32s.) These are shown in the first photo below and are the same as used on Model As.
The rest of the chassis used 9 straight tapered fittings, also the same as used on Model As, as shown in the second photo.
Both have 1/8 NPT threads and are available from snydersantiqueauto.com for $1.25 each for the angled fittings and $0.95 for the straight fittings plus shipping.
If you wish to use the more modern fittings with the nipple tips that Ford adopted starting during the 1933 model year, those are available from Snyder's as well.
If I am correct, the original 32 tapered grease fittings did not have a spring and check ball in them - whereas modern Zerc fittings all have a spring and check ball. I'm not around my 32 CAB at the moment, so I can't check - though I believe this to be true?
Unless you really care about originality and looks, I'd run the modern Zercs - as they prevent grease from pushing back out of the fitting.
With respect, the original tapered grease fittings do indeed have a spring-loaded ball check valve and do not leak any more than the more modern Alemite nippled fittings.
Perhaps you are thinking of the pressed-in fittings sometimes encountered in the tie rod ends. Not all of those had/still have check valves.
