Title: ANOTHER oil pump cable adjustment question
Post by: RDDave on January 11, 2025, 07:15:20 PM
Changing the throttle cables on my RD350. All is good except one thing; on the oil pump, the dimples do not align with the pin unless I remove the lock nut on the adjuster going into the case. If I remove the nut, allowing the adjusting elbow to screw farther into the case, it just about lines up. But with the nut in place it is clearly too far advanced. I have looked at everything, disassembled it to double check and don't think there is anything wrong. Has anyone else ran into this? Any reason not to run it like this?  Thanks

it'll be fine to do that.  however, in my experience, you can usually add freeplay at the throttle, get the oil pump cable sorted, then adjust the carbs to suit. But either way is fine.

I had the same problem but it turned out that the top end of the oil pump cable was not seated fully into the cable connector thingy. That fixed it for me and everything lined up down at the pump.

I thought that I had double checked everything, but I will go back and triple check those things.

And I double dog dare you to come up with more suggestions........

If all else fails I made a post a while back covering the differences in oil pump cables over the 3 year span of the original RD.
