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
These small cylindrical pieces were used on the road-going cars to protect the innertube valve stems from cuts from debris or stones on the road. My 250 Cabriolet had them and I have seen them on other cars as late as the 365 2+2s. I believe that they were supplied by Pirelli and only used on cars with Pirelli tires. These sleeves are tin-plated, the retaining knurled nuts are chrome-plated as are the valve stem caps. I have seen original pieces with several different finishes including some painted sleeves on a very original 330 2+2. The sleeve will have to be hand-fitted to the rims and the different sized innertube valve stems. Valve Stem Set, jam nuts and caps
The round rubber Saga universal joints have a spherical ball and socket, made of steel, in the center of the “Donut”. Because of the structure of the metal frame it is not possible to lubricate this ball and socket without some special equipment. This short steel extension was provided in some of the late tool bags. It is not shown in the 250 tool bag photos or drawings but it is necessary for these cars. I suppose that a factory-trained mechanic would have this tool and would be the person doing this type of work. This tool is 60mm long and has 8×1 threads at each end. U-Joint Grease Extension.
The 250 series cars built by PininFarina often used a special type of hose clamps on the large air duct hoses. These clamps are called “Diament” based on the manufacturer’s logo which is sometimes found on the body of the clamp. These clamps are very similar to the normal Copiglia clamps but they have a special body with a small set screw which is used to secure the strap once the clamp is tightened. I have seen these on P.F. Coupes, Series 1 Spyders, G.T. E.s and the Cabriolets. Stamped Diament with the manufacturer’s logo.
