Here is one for you. I bought a new L14 kent cam from Garry Kemp recently, and the #5 journal has a large, deep groove in it. I expect that is to be a small oil reserve on that end, with the pressure drop from the 3 previous journals, that journal would have the least pressure. I would think that would create more even oiling, and perhaps with the better distribution of the oil around the journal, even help the cam centering.
The strange thing is in all his years, Garry had never, ever seen one! The groove appears to have been cast that way, not machined! I told Garry this morning that if he had never seen one, perhaps I should make a walnut base and mount it on the wall! Must be a rare bird.
So, I machined a groove in my 107 cam to have a like function. Not so sure a real narrow v groove would not help the three narrow journals, but not trying that at this time. Below is a photo taken yesterday - the kent on the right, my 107 I machined on the left. The shafts are not silver, that is from the camera flash.
Has anyone seen one of these? Was it for a special application? Discuss.... Brian
The L14 may be hard to shim, the base circle is over .100" smaller than the 107. 1.043" verses 1.150" for the 107.
Tnx for the move Bibs, this is indeed a more correct thread! You were right on top of it, after posting in the general section, I went to edit an error, and it was already gone! That should be a record....
