seadoo 951 small end bearing

is there and one who offers caged bearing for the 951 motor/high quality ,maybe silver plated or titanium cage's? thanks chip de

Why do you want caged bearings? Cageless offer more support, due to more bearing surface. They are a pain in the ass to work with, especially if you are racer boy who changes pistons more often than shorts. To answer your question, try Wiseco or Pro-X, whoever your local shop carries.

WSM lists normal caged type bearings for all seadoo , much better than those stupid individual needles

TWIMC, Do Not use WSM cageless bearings, or any of the cheap Tiawan made cageless bearings that are on the market. Rotax uses non caged bearings for a reason. They give about 30% more bearing surface, and there is no cage to disentergrate and go through the motor. I guarantee, if you assemble your motor with these cheap cageless bearings you will be sorry down the road.

Once you have spent 10 minutes mastering the installation of a non caged bearing, it is a piece of cake. The biggest difference in the installation is that you leave both of the circlips out until after the bearing and wrist pin are in place. The non caged bearings come with a plastic sleeve to facilitate the installation. Using a pusher (which could be nothing more than a socket, if you don't have the proper pusher tool) You push the wristpin through the bearing and it pushes the plastic sleeve on through and out the other side. Even if you screw it up trying, you can put the bearings and the plastic sleeves back together and try again until you get it right.

The only place I might consider using a caged bearing would be when time was very important, like between rounds at a race, When the engine is still in the hull and where every minute counts and doing it any other way, may make the difference between getting to the starting line on time. Then, I would change the bearing to a cageless as soon as I could. An 88mm piston is pretty big and heavy. Don't count on 30% less bearing to do the job of the proper bearing for any length of time. 30% less heat transfer too, in a bearing that can get very hot.

IMO, if you cannot master something as easy as installing the correct bearings, get some help from someone who has taken the time to learn to do the job correctly. Now, if you are such a poor tuner that you know you will be changing pistons every race, that is a different story.

bill I agree with you and everyone as to area,but have customer who whats caged bearing (working on his own machine) and was trying to find premo bearing thank all chip de

To answer your question, I believe INA and Thompson both make what you are looing for. You might also check size of larger Honda or Yamaha motors to see if they use a pin that diameter. If so, you have a match.

Even if you find the 21mm inside diameter, the outside diameter is different.
