This is the shallower type of Model 30/40 main bearing plate that was fitted to very early Cammy engines - we believe prior to 1933 (although it is difficult to be exactly sure when the lip was made larger - so please ensure you check your engine . . . there may be a year or so each way before the new lip type was introduced).

Price is each

If you have an early engine and are not sure which type you need, then measure how far the bearing lip stands proud of the inner crankcase wall (as In photo 2) - if it sits approx. 0.225" above the crankcase wall then you need the later type (Item no 0285). If it measures approximately 0.175" above crankcase then you have the early type crankcase and you need this bearing cover. The early type crankcase is on the right on the 3rd photograph.

We also sell the later post 1932 Inter bearing cover . . . and although they look very similar, you can see that this earlier cover is noticeably shallower.  And of course - being early, and only fitted for a short period . . . they are extremely difficult to find, and orginals are often damaged and dont solder well.  We had this cover specially made for us, based on an original plate.
