Hi all - Thirsty for experience and knowledge. I am trying to find out if the rear drive sprockets on a Mitsubishi bd2g are the same as those on the Komatsu D21 series. also Looking for the (4 way) blade hydraulic ram seals if any one knows where to get a kit please..
Measure the diameter and count the number of teeth to see it it matches Komatsu. You may be able to buy the outer ring and weld it onto your sprockets if they are the same. Other things to check are the centre hole and offset( how much they are dished).
You can buy Weld-on sprocket rims for the BD2F & BD2G on eBay or thru other suppliers.There are many Asian aftermarket suppliers on Alibaba,etc. The pictured rims are BD2F ,with 27 teeth. . Mitsy & Komatsu D21 are all 135mm pitch chains,or thereabouts.
