Selecting the left side main crankshaft bearing has long been confusing, as there are three different conditions of this bearing, all using the same part number, 70-2879. This RHP MRJA 1-1/8 C3 roller bearing features increased diametral clearance over the CN and C2 versions. Due to the behavior of aluminum crankcases that have survived decades of service, sometimes it is necessary to use a bearing with more internal clearance to achieve a smooth operating bottom-end in your Triumph 650 engine.

Please consult your machinist or engine builder for guidance if you have any doubts about which version of the 70-2879 RHP MRJA 1-1/8 to use in your engine build.

Please note: Due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
