I have an 04 yfz 450 and today I went for a ride and it appears to me that the shaft that the shift pedal attaches to broke inside. I have not really looked at it yet cause i have to pull the entire engine and split the case to investigate more. I was just wondering if this is a common problem on the yfz's and if they made a stronger shaft to put in them. I only want to have to do this one time cause it's a lot of work.

I haven't heard any common issues. Have you taken off the shift lever and checked the spline? Check to see if it is stripped out. I'm not aware of any hardened aftermarket shift shafts.

I attached a parts diagram for you..:wink:

The shift lever is still solidly attached to the shaft, but the shaft spins freely in the transmission. You can pull the shaft in and out also. It's something on the inside. I am going to start pulling it all apart and split the case this weekend. I will figure out what happened at that time i guess. Thanks for the diagram. that will help.

I bet you that shaft is coming out of the end plate bracket. Good luck with it!

      2006 Arctic Cat Utility transmission drive shaft replacement.
      By Shorty51
      Good morning, I am new to the forum. I'm 75 years old and love getting ATVs back to usable condition. I particularly like the 2006-2009 Arctic Cat 250 Utility. I currently own 6. The 2006 I am working on only has reverse and low gear. The "drive shaft" in the transmission is completely stripped where the high gear would mesh. Has anyone on here replaced the shaft. I'm told I have to split the case. I was hoping that someone on here could let me know how hard it will be. I already have it stripped down to where the shaft coming in from the clutch side is the only thing left. I was hoping I could just remove the driven clutch and drive it out from there. Directions say different. Any help would be greatly appreciated.

      2002 Polaris 400 Sportsman Shift Indicator Issues
      By jeffrocdx
      I'm working on a 2002 Polaris Sportsman 400 with shift indicator problems. The indicator panel only will show Neutral and Reverse. If it's in High or Low, the indicator will show "R".
      I have replaced the three position indicator switch on the transmission. There is also a two position switch on the tranny that I didn't replace. If anyone is familiar with this problem, please let me know what I need to do. Any help is greatly appreciated!

      Need Help with My 2021 Polaris Sportsman – Engine Stalling Issue
      By digrig
      Hey everyone,
      I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
      Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

      Is the grizzly 700 engine compatible into any UTV's?
      By Ironworker709
      I have Grizzly 700 that has been pretty much totaled out in a bad accident, but it will still run and drive good...
      Will this engine swap into any of the Yamaha UTV's like thr rhino and Viking 700's?
      Was just going to sell it as is for a engine for someone who needs one pretty cheap..but been thinking about getting a UTV for the family and maybe find one with a blown engine cheap and swap it out
      I already an excellent shape 2001 Big Bear 400 4x4 for us..but kinda been looking for a good used UTV for us and the grandkids on our property to play with
      Not sure of the year..i can't remember what year it was when i picked it up for a buddy a few years ago..he went to jail after he totaled this thing and told me to pick up a few things at his house he was renting and just keep them for myself since he owed me a bunch of money before the landlord sent them to the dump...
      The first picture is when i went and picked it up for him..second is how it is now..frame is all twisted up and plastics are fubarred..going to sell the rims and tires.they stick out way too wide on my Big Bear
