Motorcycle Questions? Ask a Mechanic.
Hi and thank you for your question.
I am not sure which needle bearing you are asking about. Are you asking about the ones that the swing arm pivot on or the ones for the shock linkage?
Here is a diagram so if you could let me know which ones you are talking about, I would be glad to help you.
Thank you for the additional information.
Are the tapered end of the needle bearing and the seal on opposite ends of the bearing?
The seal would be installed so it is towards the outside of the wheel, and the taper on the inner race would go in first, towards the inside.
The seals are installed to keep dirt, water and debris on the outside. In simplest terms, think of an axle with one bearing on each end, pressed into the hub of a wheel. The seals would both be facing out so nothing could get in to the bearings from either side.
The one pic you sent that you could see the needle bearing was showing the inner end of it. The seal on the other side of what is pictured would prevent the water, dirt and debris from getting into the needle bearing, and the seal on the other side of the hub would protect it from the other end.
Honestly, I do not understand what you are asking me nor do I understand why you keep asking the same question. All parts diagrams are the same, and I have looked at them during the course of our interaction. What is it specifically that you are unsure about that is preventing you from installing the bearing? I consulted the factory service manual on your bike and they make no mention of any special procedure that would indicate this is anything other than a typical bearing exchange. Based on the diagrams and service manual, the information I provided for you is accurate. Perhaps think of the needle bearing being installed by pressing it in from the side that has the seal on it. Does that make more sense?
