Imtoorelaxed

I had the same problem. Shaved the head, new head gasket, new water pump. Nothing worked. I ended up just buying a new drop in motor. But as I thought about it, I never checked to see if the water pump was actually turning. I am guessing that the chain that drives the oil pump and water pump spun off. If I ever find the time I am going to disassemble the old motor and find out. 2018 750 challenger crew.

Thanks Travis. Now that you mention that I remember reading about that somewhere too. And i was't buckled when i took for a test drive. The indicator on the dash is on/off sporadically too. Previous owner must have tried fixing an issue with them as all four buckles are taped together, probably trying to trace problem. It's at my cottage, I look at that this weekend.

I recently purchased a used 2016 Cub Cadet 750 Challenger Crew. It has never really ran very smoothly. I just replaced the clutch which was badly worn. But when driving in high it revs to 5400 but doesn’t seem to shift into high gear. It only reaches 20mph. I’m using Amsoil 10w40 Utv oil. It also sputters at that RPM range. I’ve ordered a new injector and am going to add a fuel filter. I’m hoping that will help with the sputtering but it the transmission issue I would like some suggestions on. Thanks.
