Recently bought Max from a relative. Went over the whole unit to make sure it was working fine. Unit had 40 hrs. Kids were riding at the farm for two days. I went to take it on a ride and noticed a clunking banging noise. Found the long bolt to the drivin clutch was loose and wore a small hole into body. Tighten- then rode it- loosened up within 5 minutes. Bought new bolt and lock tite. Thought it would be good- Started riding in not so nice area (hills&slopes) when lost all power and braking to wheels. Was a bit hairy at nightime...on a hill. Bolt was still tight. The Max had to sit up there for a year till we could get it down. After talking to RI found I had sheared the woodruff?? key on axle of trans. Replaced and put back together to find a two broken bearing collers on front tire. Replaced them, and noticed none of the inner bearing flanges had zerks--all outers did though. Question: I've been reading here alot, but have not heard mention of the woodruff key shearing or no inner bearing zerks. Just got done getting the 16 hp B&S running good followed much advise from postings..A tip cleaner(on main jet) really solved 90% of the stalling and rough running. Thanks for any input Tom---This is a great site!! |

Tom,
I'm not sure on the woodruff key on the axle. As far as the inner flanges go, the machine probably originally had bushings and the last person did the cheap upgrade by using flanges without zerk fittings. Maybe it came from the factory that way some of the gurus on the board might have some insight. Mine was in the same situation with my machine it's a 92 Max IV. When I replaced the outer flanges this summer I used the old zerk fitting flanges for the inner ones. Now I have zerks at all my bearings. When I bought new flanges I bought 3 hole flanges and drilled them for the four holes on our machines. I didn't call RI because they are now using the larger diameter bearings so I assumed they wouldn't have the old style flanges.
Now about the bearings I'm sure you know that the smaller Cams on the older machines are the weak point. If you get tired of replacing them because of the broken collars. Check out the thread in shop talk about non eccentric setscrew bearings. My final solution has worked great with no problems

tom am i correct that you ment:
the tranys "input shaft" had a broken key?
(driven pully puts tork to the shaft threw the key)
so the engine was unthreding your bolts huh,
thats a new one beleave it or not, so your braking the ground here.
but in a while the postings and threds with some realy great info and advice can become buiread and lost.
someday someone new will ask about this trouble too, i hope your listening in at that time so they can get the strait answer right away. |

Hi Tom, it sounds like you have an older Max IV by your description. It is uncommon to shear the key off the tranny shaft but it can happen. I'm very surprised this has not been an issue with the 25/27hp engines. Polaris quads and other auto ATVs use a splined trans input shaft and that's the only right way to do it.
The Max IV always had inner bearings (the Max II has bushings up to 1996). Older Max IVs did not have greasable inner bearings like the new ones. Also, the outer bearings on all machines were upgraded to the larger 72mm bearing to solve the collar breaking problem. Your machine probably has the smaller 62mm bearings inside and out and that is why you had the broken collars. |

David-(yes) I believe a good cause- after tearing apart to replace the key,, I noticed the rear trans. bolt was gone--it had wallowed out the slot. That along with the kids thinking it was a four-wheeler riding all day and the hard full speed turning probably was the cause.. I work for Timken's and believe they could cross ref. to a 72mm bearing. They couldnt for the 62mm. Did not know at the time they (72mm) would work. Are different flanges needed to go to the 72mm?? |
