How tight should the oil pump be...

...after performing the "servicing" or lapping procedure? I may have gone a little too far with mine. After cleaning and reassembling, it was tight enough that I could not turn it by hand. But the service manual (section C25) seems to say that is ok. They talk about feeding some oil into the pump and turning it with a ring spanner "a number of times". They note it should have "freed off considerably" with that.

So I did, and it did free up considerably, to the point where I can turn it by hand although it is still fairly stiff. There's no endplay in it now however! :mrgreen:

So am I good to go, or should I work the gears down slightly?

first time for this procedure,
Debby

Hi Debby : The job is just that simple that you end up second guessing yourself. If you've followed the book then you're done .

As I remember you want to look to eliminate all play, The pump should be able to turn by hand but with increased resistance, showing the gears are in contact. If you can turn by hand you should be OK.
Let us know if the bike still wet sumps......mine still does!

Hi Deb:
I did the same thing on all my commandos.They work just fine.It will slow your wetsumping a little.The tech digest method of doing the spring in the cover works well.I did the o ring fix myself in the pump on all of mine.That along with the cover solved all wet sumping issues.
