Hey guys, 3 seasons ago I threw my bottom end together and asked some of the local "yamaha specialists" if it would be wise to grease the pto side outer SEALED bearing. Their response was that I would almost certainly melt my engine down, then continued to tell me that the bearing in question was not a sealed bearing and was lubed in the same way the rest of the bearings were.

Anyways, I have been around many 700 triples that have had outer bearing failures (mine was very close the first time I took it apart) and decided to try it greasing it. I tried it the next season after installing the bearing and the past season.

I can't leave good enough alone, so I am currently in the process of cleaning up the ports and inspecting the rest of the bottom end. I just finished tearing the bottom end apart and inspecting the crank bearings. I must say I am very impressed with how well the sealed bearing has been holding up! It is in very good condition and I have around 4500mi on it now.

So, if anyone wants to benefit in the same way I have, here is how I did it.

1. Remove the primary clutch.

2. Wipe down the seal area to remove any debris in the surrounding area.

3. Remove the outer seal from the outer bearing on the PTO side of the crank.

4. Use a small amount of grease (like a pointer finger tip full) and rub it into the bearing. I would recommend a high quality grease with a low temp rating. If you over-grease it will be pushed out on past the seals, so only a small amount is needed.

5. Reinstall the seal.

6. Reinstall the primary clutch and torque to the specs in the technical section on this site.

Hope this helps!
 

i have a question for you, this is the first time ive tried taking my clutch off, so i bought a clutch puller online that said it was for an 00 sx700r. when i pulled the bold out and put the clutch puller in it threaded very nicely till it was like 3/4 the way in and then got tough. as i kept tightening it there was a pop sound so i thought it popped free as i saw someone do on youtube. only it didnt pop free, and my clutch puller wont thread out all the way. it gets to like 7/8 the way out and then just spins. any help?

That sounds very strange to me. Your clutch puller should have threads just before the hex head that you put your socket on. Is this correct? This confirms that the puller was threading into the clutch and not the crank. Is the clutch loose at all? Has the clutch pulled away from the engine at all? I am pretty stumped without having some of those questions answered.

probably a cheap no-name puller and it's bent/broke and stuck in the clutch.

My thoughts as well. If clutch is loose from crank but wont come all the way off I suspect puller has bent enough to engage into the threads in the crank. Short of putting a slide hammer on puller and giving it a tug or two while hoping for the best..........
 
i figured it out lol. as you said it was bent inside the clutch. i was able to pull the clutch, then tap the puller out with a bolt and a hammer :)
