Triumph Crankshaft Main Roller Bearing NOS 70-2879 Drive Side SKF MRJA 1 1/8 CN
Genuine! SKF Triumph Crankshaft Drive Side Roller Bearing. Looking for the best quality bearing to install into your Triumph? Well you have found it! This bearing is "New Old Stock" and is made in England! Comes with ten heavy duty individual rollers and a steel cage! Fits all Triumph 650 Unit models (Bonneville, T120, Tiger, TR6, Trophy, TR6C, T120TT & T120C) from 1966-1972. For the unaware this bearing has the correct "CN" or "Normal Clearance" for 1966-1972 650 models! There are three types of clearances sold under the same part number of 70-2879! If your 650 model falls under the years of 1966-1972 we recommend installing this "CN" bearing! Installing a bearing with the wrong clearance could lead to engine failure, seizure or vibration. Please refer to your parts catalog for proper fitment.
*Please note that some early 750 TR7 & T140 models up to approx 1975 where installed with a "CN" bearing. It is always best to examine your original bearing before choosing a replacement!*
