Dropping chain case?

Just call Tom at Tki and he will get you lined out. You will need an inner chain case for a 17 which I believe are around 150. Then if you talk to Tom he will get you the new gear and belts you need and the template to bolt on. If you do a swap of your old belt drive with him it should run around $500 when it's all said and done if you do the labor yourself.

16 update
I did it to my 2016 ltd and am very happy with how it turned out and how good it works.
You'll need 8 tooth drivers if you have a 3" track and 7 tooth drivers now
2017 MC TKI templets
2017 MC inner chain case
2017 MC belt drive cover
You might need a lower gear ratio after going to 8 tooth drivers.
You'll also need good tools to cut and trim the tunnel.
TKI's templates and instructions are very good.
To mark the black tunnel (if that's what you have) you'll need a white marker of some kind.

There's been a few threads on here with pics and good info.
A quick search should get you more info.

You'll also need the lower covers under the sled for both the brake and chain case side. Light modding of the brake disk cover needed or buy the mountain cat one. Your belt drive kit will need almost all the major parts exchanged for new ones other than the tensioner. Pulleys, cover, and even the belt are different. Lower pulley needs to be smaller two-piece part to get it installed so upper pulley needs to change to keep the same ratio. Like others said Tom at TKI was working with guys on these swaps so get ahold of him.

You are right.
I forgot to mention those things.
Like I've said a few times I've done this MC update to my 2016 LTD and love how it works. The guys I ride with will also tell you they noticed the difference right away.

It's vulnerable. That's why I'm not doing the mod. I do ride early season and low snow locally with my kids. I know you gain a lot by the drop'n'roll, but not worth it to me "just in case".

I was looking at my 14 and it already looks like it's asking to get hit, I think I'd be really paranoid with another inch or so hanging down there.

MC chain case
I can't remember reading or hearing anyone saying they've bent a drive shaft or smashed a chain case because they've hit something. That's not to say it won't happen. There's going to be a lot more sleds on the snow next year with the drive shaft in this location.

They definitely hang down there. Maybe not quite as bad as the new Doos which there seem to be a fair amount of those with smashed cases if you jump to that side of the forum. My buddy's catches pretty good on the break over point on his sled deck. I'm running the cat add-on skid plate for some extra insurance with my conversion.
thats sorta why id be worried about an aluminum shaft. unless its the big diameter hollow one like a doo, those seem to hold up. ? but i havent hit mine yet, i find you can REALLY slow down if you see a risky lookin bump on the hill. even in the worst spots. It picks right up out of the snow when you let off and ease back into it. not sure you could let off that much on a steep hill with the non-drop. I dont have much time on the old case sleds.
it really amazes me what these things will climb. im rarely ever WOT. but it looks like pretty significant surgery, if i had the older case id prolly just put 8 tooths on and ride.
