Ferrari used the Button type grease fittings on all of the cars prior to the 275 series which began using the more familiar “Allamite” type. On the 250 series cars the tie rod ends used the “Allamite” type grease fittings. This pull-on type adapter is appropriate for other Italian, French and English cars using the button type grease fittings with the head dimensions of 15mm across the flats and 2mm thick.

I looked and looked for correct Pirelli fan belts for my old 250 Cabriolet with no luck. Finally I made a silk screen jig and began silk screening modern belts with the correct old – style Pirelli information. My silk screen and jig can only do the long belts for the outside plug engines that had generators, and the very short belts that were used on the front mounted generators on inside plug 250 engines.Long Belts for the 250 Outside Plug Engines with Generators
On some of the cars it is often difficult to use the original equipment “Pull-on” grease adapters. This “Push-on” Type grease adapter will work for most of those tight spots. This is not a Ferrari factory-issued tool, just one that I found and thought would be useful. Push-On Grease adapter.
The early outside plug 250 series engines used a small carbon brush assembly to activate the cooling fan clutch. This is a pencil-sized plastic assembly, held in place by a spring clip, with a small spring-loaded carbon brush that sends an electrical signal to activate a magnetic clutch to engage the radiator cooling fan. The design was improved on the later 250 cars with the addition of a second ground brush. The earlier assembly is shown on page 285 of Dick Merritt’s book Ferrari:Operating, Maintenance, and Service Handbooks 1948-1963. The later configuration, with the ground brush, is shown on page 170 of the “Carbooks” 275 Manual reprint. “Hot” Brush assembly with the retaining clip
