need inner and outer boot for rear drive shaft bayou 300C13

[Bowhunter 1]

I tore the outer and inner boot on the rear drive shaft of a klf300c13. the dealer said they only sell the outside boot and the inner boot comes with the cv joint at a price of $404.00!!!
can anyone help? to make matters worse, the oil retention cup inside the cv joint keeps coming dislodged and I can't seem to keep it in place. any ideas?

The CV joint itself is a sealed unit only available as a complete joint assembly, so the dealer is correct.

I am not sure what you are calling the oil retention cup, but if it is the internal barrier seal it requires the covering on the sealed CV joint to hold it in place.

The price should be closer to $300, so I would give the site sponsor a call and you should be able to get enough of a forum member discount to just about cover the freight.

Thanks for your reply. I think thats a lot of money for a boot!! I was hoping someone would make a boot that size that I could substitute with. The part I am referring to as a oil retainer I was told is a grease retainer for the cv joint. it sets inside the cv joint between the splines and the bearings. Because the spline shaft is hollow and the main seal fits around the outside of the cv joint end, I don't understand what would keep the oil inside the the engine if that cup were loose. If you were to remove the cup the oil would have a straight path to the bearings in the cv joint. Sorry if I'm not explaining this well, I don't know ANYTHING about engines

It is a lot of money for a boot, but you get the entire assembly because the boot is shrink sealed to the CV joint. I do not believe I have ever seen one of these lose the internal CV cover before the CV itself failed.

I do not quite grasp which seal is not staying in place. Go to Kawasaki.com and follow the Owner Info tab to the parts diagrams and take a look at the diagrams for the component involved.

All I can think of is the drive shaft spring that loads the drive shaft so it stays against the transmission bevel gear drive spline may be missing and allowing the entire assembly to slide back toward the differential.

I can't find the part listed in the parts diagram. the only other way I can explain this is..... if you take the cv joint off the rear drive shaft, then take the bearings out of the joint, look inside then and you can see a seal or a dust cover (that's what Brink told me). Thats the cover that keeps coming loose and the engine oil follows the splines into the joint and hence the problem. What I did was have the local machine shop cut me a disk about 3 thousands larger and he pressed it into the joint. Its not coming out now without a large hammer and drift! I also went to a Polaris dealer and matched a boot that will fit around the cv joint and the outer boot will be in soon.
Then to solve my problem further I am going to SELL THIS QUAD as soon as possible because its been a headache since the day I bought it!! Thanks again for your help!

ahhh you cant sell it now you about got like brand new now,

can i ask how the cv boot etc failed in the first place?my 86 bayou300 still has original boots and shaft pieces and had no issues yet.except when i pulled a long wheely the clamp come loose at the motor side of the shaft due to hittin the frame on the angle i was riden the wheely at lol.lessoned learned not to pull a long wheely with a shaft drive lmao.

i just want to know what happened so i can pass up on the fun of repairing it .

so polaris had a boot kit for the bayou huh.thats good cheaper than 400 beans for a flippin shaft .-corey-

[Bowhunter 1]

I had it in the woods setting a tree stand and I picked up a stout stick that cut through both boots. I will be a little more careful about what I drive over from now on. I don't ride hard and I don't drive fast but I do take it off the trails a lot to get me close to my stands or to drag deer. Just getting a little to old to do that stuff any more.

[86klf300guy]

lol. maybe make your self a shield that covers the back end where the shaft rides at to help from them darn sticks jumpin up and gettin your machine in costly repairs.

i used plexy glass and made a shield that moves with the suspension to do the same thing protect it .i get my self in sum deep mud and ruts this helps me out -corey-

sorry I haven't responded to your pm bowhunter, but i've been busy. I understand what you're describing, but there shouldn't be oil in the shaft and the only purpose of the "dust cap" is to keep the grease in the cv joint from being contaiminated/escaping. I'm trying to find where the oil may be coming from, but I'm not having much luck. I just rebuilt my driveshaft (bearing was completely gone) and when you take it off there should be no oil leakage so this is where I'm lost. Glad to hear you found a boot and cap (I used a freeze plug) Still trying to figure out where the oil is coming from (perhaps the shaft is cracked?

[Brink]

if oil is coming from around the shaft instead of through the shaft the oil seal is bad (92050 if you look at the micro fiche)

[Bowhunter 1]

Hi Brink. Just got your post. I've been busy also. I am a little worried now. I replaced that rear seal last year and I thought as long as I am replacing all this other stuff I might as well change the seal again. I ordered one and it came in today only to find out that they sold me the wrong one. Gee what a surprise.
anyway the guy who is putting this together for me said not to worry because he thinks the old one is good. BUT.... after thinking what you just said that has to be the problem otherwise how could the oil get to the splines and into the joint. I will keep checking the outer boot. if it fills with oil I know the rear main seal is shot and I will have to take it apart again. (fourth time) Thanks for the insight!

Bowhunter, I have a KLF400B6 which has the same drive train as the bayou 300. I had to pull my rear end to replace the outer drive shaft boot and the left axle.

I looked at my inner boot and it looks to me that a front CV axle boot would be sufficient to replace the inner boot. It's a little longer but for $400, i'd make do with it being a little longer.

[Bowhunter 1]

thanks 99prairie. I used a front axel boot from a polaris and it works just fine.
$30.00, not $400. for a Kaw. I think I will start listing them on ebay as a Kawasaki replacement and make a few bucks lol. thanks for the reply

[99prairie400]

I think that the front CV boots from a lot of the quads are inter-changeable. I just happened to have my rear end apart and looked at that inner boot. I know if mine ever gets ripped, I'll be ordering a bayou front CV boot kit and giving it a try.
