How to check oil pump output on DT2? was created by AirborneSilva
Hey guys, it's time for me to check and ensure the oil pump is putting out the proper amount of oil, what's the procedure for testing? Thank you - Tony

I found in my repair manual, 2 different measurements of oil volume I had to check…
First one was the throttle closed, and rotate the plastic thumb wheel on the pump.. I don’t recall how many revolutions… maybe it was 100?… and I placed the output tube of the pump in a syringe so I could accurately read the volume of oil.
The second one was with the throttle wide open and the same process was repeated….
Mine was very close to what was recommended so no further adjustments..

Thanks Sneezles61, I seem to remember reading somewhere that it is 100 revolutions and 10cc's. I was hoping there would be an easy way or reaching that 100 without sitting there turning it for 100 revolutions. Thanks again!

You can always cut that in half… BUT…. That’s cutting corners and that doesn’t seem to end well… there is always an option…

I agree, cutting corners usually ends up costing in one way or another...

Could run it on premix for a bit & run the motor marking the plastic wheel & count 100. Block of air into the cylinder or it'll run too fast for idle leaning out a little.

Had thought of that but assumed it may run too fast for my old eyes, will give it a shot... Thanks!

Don't count wheel, count pump plunger strokes. Very easy.
Pretty sure number is 200? Volume charts are probably in Tech Library manuals or bulletins.
Lots of posts on this topic and even at least one video if you search.

Good morning Mark, I do have a video bookmarked but it's for a later model DT so wasn't sure it pertained to my year. Thanks for the reply!

While some revisions were made, Yamaha motorcycle autolube pumps are functionally similar from the very first ones in the early 1960's through at least 1980's.
You have the starter wheel on the early models... can be spun by hand or power tool... only spins one direction... or premix and run the engine to cycle the pump.
Earlier models didn't give output volume specs. That started later... I can't remember right now if later manuals gave earlier model specs? Finding specific oil delivery spec is probably your biggest challenge.
