1998 Bayou 300 4x4 Rear Shaft Boot/Seal

Recommended Posts

Hi all, 

I purchased this quad from Craigslist somewhat against my better judgement due to the fact that the driveshaft boot was leaking oil.  I am assuming it is just the seal that needs replacement.  Does anyone know the part numbers for the seal and boot?  I am also trying to get a hold of a service manual for this so I am not going in blind!

Thanks for your help!

I haven't tried that site yet but I definitely will.  Thanks for the tip!  So far I really like the quad.  Runs pretty well so far but needs some work--to be expected on a '98!

I checked the site and they have the owner's manual but not the service/repair manual.  Do you have experience working on this machine?  I am wondering whether parts are pricey/readily available.

the seal that usually causes this is the crank seal symptoms besides the leaking thru the boot will be steam/smoke coming out of the pull rope housing when it warmed up good.

I just completed this job and I did remove the rear end to get to the seal but not much to it.  Just had to support the rear diff (used a jack) and the quad with a cinder block and a few wood blocks under the frame near the motor.   I did everything per the manual except I did not remove the brake panel as it was seized on the axle pretty good. I unhooked the brake cables and just unbolted the rear shocks and suspension arms to remove.  Then I unbolted the seal hosing/holder from the subtransmission (4 allen bolts) and replaced the seal.  i also replaced the o-ring on the prop shaft.  The job went fairly smoothly but not sure if it solved my problem yet since I still have the right rear wheel off to service the brakes.  The shoes are rusted onto the pivot pins and I have been trying to work them off with some PB blaster and a prybar since they are seized on pretty good.  Any tip on removing these btw?

Nice work on the rear. 👍 you can try to use a torch.  The type plumbers use to sweet pipe.  Put a cold water rag over the area of bearing to not burn anything up. Stay local on the area your heating. The expansion and contraction of the metal should free it up.  

Take your time ! Keep all areas that you want to keep cool covered with a cold wet rag! 

Good luck and let us know how you make out.  

🍀

Also take. A look at the rear bearings while your there since it would be a shame to do all this work and have a bearing go later. 

Maybe better to swap em out now ?

Thanks for the tip Frank--that's just what I did.  Used a propane torch on the pivots.  I wish I had thought of your wet rag idea but I didn't heat it long enough to heat the axle bearing I don't think, maybe less than a minute.  I then sprayed some more PB Blaster and gently worked the shoes back and forth (or up and down I should say!) with a short piece of 2x2 and a hammer.  I was eventually able to get them off.  The shoes have probably been seized a long time since they don't look too worn.  I will try to reuse them but definitely applying anti-seize before they go back on!  Now I just have to get the damn brake cam out and sand it down, apply some anti-seize etc. since it is stuck pretty good too.  It still turns with a pretty good whack on the cam lever but nowhere near easily enough for the cables to pull.  Do you know if I need to remove the cam lever by unbolting it or should the cam just pull out?  Thanks again!

I’m not 100% sure on the cam lever but I’ve seen a small clip that held some of them in place. You can let it sit 24 hours on it with a good grease and it will work it’s way in and prob move freely after 24 hours. Grease is good bc it migrates into the surrounding metal and will get in pretty good.  Also take a piece of sand paper and hit the pads before you put them back in just to scuff them up a bit.   

Also be selective where you put the grease! The last thing you need is a blob of grease coming loose and getting on the brake shoes after a little riding  😬 

Did you happen to take any progress phots while you were doing any of this. I would love to see as well as a other QC members. 

Great work brother!!

Good luck Andrew--let me know if you run into any difficulties as I may be able to guide you through it. 

 

Thanks Frank-- can't wait to get her running again.  I didn't get any shots of the seal placement and wondering why the heck I didn't think of it!  I will try to take some shots of where I disconnected the rear end from the frame, etc., as well as the brake job I am dealing with.  I will try the grease tonight as well.  Hopefully it will come out relatively easily.

      OK, sooo  I finally did the old skid plate and screen removal to clean out my oil sump during an oil change...  This bike only has a couple thousand miles on it.  Runs like a top still...  Very few issues over the years after buying it used.
      But boy I wasn't expecting to see this!  Piece of a circlip, stuck up in the screen, and a another shard of metal and maybe a piece of gasket material.  Nothing in the oil but that...  Pristine otherwise, and still runs like a top.  Always has.
      Soooo, is it a wrist pin clip?  That's the only thing I can think of like this that could end up in there.  But definitely wanted to throw it out to guys that have seen the innerds of these more than I have.
      The valves on this thing are still within the factory spec even.  Been a really good lil workhorse...
      Any other ideas?

      First of all sorry I have been MIA here for a while, been busy with school and work.  I'll try and reply on some other threads asap, but posting this one because I just picked up a 2017 sportsman 570 before the new year and popped a boot on it going through a mud hole.  The former owner had aftermarket axles on it to accommodate the 4in lift and idk what brand they are but they're skinny as heck and idk what boot to buy to rebuild with?  It's the rear right lower boot (under the brake calp.).  I'll post some pics when I can and sorry again I've missed yall on the forum!
