DetailsEarly Cosworth YB & race spec SOHC Pinto. Genuine Cosworth spec bearings - half plain/half grooved
Genuine Cosworth bearings manufactured by Vandervell. Journal diameter 56.725/56.709mm. Keep width: 3.9mm block & main cap.
To YBB1613 - what does this mean?
Early 3 Door Cosworth models with engines up to number YBB1613 (this number is stamped on the front face of the block just above the water pump) had slightly different bearings from later engines. The bearing keep (or notch) is the same size in the block and the main bearing cap. Engines produced after this have a wider keep in the main cap. Therefore if you try to fit later bearings to an early engine, the main cap bearings will not fit unless they are modified. This change in bearing design makes it impossible to fit the bearings incorrectly in later engines- grooved bearing in the block, plain bearing in the cap.
What's the difference between Cosworth YB and Pinto main bearings?Ford SOHC Pinto
Apart from the keep width in later engines mentioned above, the difference is the main cap bearing. The Cosworth engine uses a plain bearing which is capable of taking greater loads than the grooved bearing found in Pinto sets. Whilst a Pinto set will fit, we highly recommend sticking to the correct bearings that Cosworth have always specified for Cosworth YB applications. This also means that these bearings are suitable as a HD replacement in all SOHC Pinto engines.
