bigger sledge hammer usally works

read my post of cchallenger 750. they are total crap. i have threatened to sue them, they do not care. told them if it breaks down again? i am taking it back to thier factory and set it on fire .biggest piece of junk i have ever bought. but i calmed down and am trading it in on a kubota diesil i should of bought the kubota instead.

yup it is rivited on the cam. and since you cant buy the head cover you have to buy a new head. for over 500 bucks. plus a new cam plus have the engine torn down to see if there is anything inside the bottom of it so 1500 dollars later   lol junk

started to smoke    so needed new rings and shop said bearing also  had to put in new liners and pistons.  that was at700 miles at 715 the cam compression release shot thru the head cover

i bought  a new cub cadet cchallenger 750  in 2018 has less than 800 miles on it. 4 clutches.this last clutch was 1200 dollars. thier new heavy duty 2 complete engine overhauls  and a new head/ cub cadet blames the owner. will not honor thier warrenties. and blames the owner. i do not abuse it.  it is garage kept. so far ihave almost 20 grand invested inc;luding the purchase price. could of bought a polaris for less. as you can tell i am not happy. thier parts  they sell are junk. had to buy a new head because they dont sell the head cover seperatly.compression release went thru the top of the cover while idleing be warned. they are junk.

i  have a challenger  2017 750 also. sounds like your clutch is going out.i have had to replace mine 4 times. have less than 800 miles on it. also i had to have a new engine  in it. plus now the cam  broke.  so it needs a new head. broke one of those compression release rivets.  id tell you to spend the 900 to get the new heavy duty clutch.
