Ok, so back to the oil pump issue...which isn't really an oil pump issue, but rather an oil pump drive issue (at least in my case) with all kinds of confusion over the various methods used to actually drive the oil pumps in the 1111 series saws over the years. Here are a few pics to set the stage for a pretty crappy video that is by no means definitive (Hi Dave!!!) and which also contains some inaccuracies both in terminology and the actual scope of what I was attempting to explain. Just figured some basic verbalization along with even some
minimal visualization may help...and the visualization is certainly minimal since I just set my phone down on the bench, hit the record button, and went for it. There is definitely more to this than what I've put together so far and I'll try to get some additional detail posted like cross-ref'd part numbers and such...of which there are a bunch...but for now just wanted to spew out some sort of update for the huddled masses with all the wrong parts on their 1111's wonderin' why the damned things won't oil.
And there are a few other variants of these drives including a spur approach that uses the lug-style worm and what I've seen reference to as even a lug-style worm that fits the old style pump (at least in old docs), though that's some really muddy water and probably why so much of this confusion exists in the first place. Anyway, here's the basic rundown. Hope it helps make some sense out of a pretty damned rambling video primarily focused on the crank of an 051 with only the most fleeting frames of actually relevant examples of what I was trying to convey! I'm certainly open to any / all questions anyone may have on all of this....., or more answers and more iinfo on the subject from anyone who can provide it. That's obviously the whole point! And I am aware of the variations and improvements over time of the oil pumps themselves, but that stuff is fairly well documented and not nearly as confusing as the drive issues.
Cheers, gang.
