New, Old Waverunner Need Help

[shipwreck]

YAMAHA 500 CC WJ500 1989


JUST BOUGHT IT , I HAVE MANUAL .

I SAW A GREASE FITTING ON INTERMEDIATE SHAFT.
If i grease that will it grease the two bearings in housing?
If so how much grease? What kind?

I am hope this will take care of the loud noise and viabration when started, it sound like metal hitting something (ching ching sound).
I did a compression test 143 psi on both cylinders.



What are some good part websites?

Re: New, Old Waverunner Need Help

it probably has bad bearings or a bad pump liner hitting the impeller

Re: New, Old Waverunner Need Help

The fitting you are talking about is only for the drive shaft bearing.Use MP grease and pump 2 to 5 pumps or untill you feel it getting pressure.You don't want to blow out the seals.
Check the impeller and see if it is hitting the wear ring, It sounds like you pump bearing is out.On the very back of the ski in the hole where the water shoots out there is a cone held on with 3 bolts.Take them out and look at the bearing.There is a bolt in the middle of the cone but it is only for takeing out and putting in grease with the same grease gun.

The best web site for jet skis is PWCTODAY.COM
