I don't have any hair line cracks in my track. My guess would be that somene drove the snowmobile through ice melt / salt and this dried out and cracked your track.

Note: I purchased a second one of these sleds for spare parts just for this purpose.

I also thought about building a custom belt drive train but there is not a lot of room to gear it down but I may try this with the spare parts sled. Let me know how you make out with yours.

I have also attached pictures of my gear train and the part number for the pinion I used.
