So I’ve gotten an 07 renegade 800 that spun a connecting rod and fried the crank, rod, piston, and casing. Bought new everything from mrrpm and all went together really smoothly except I’m having problems with the engine head. Following a YouTube video (shanesoutty) + the manual for assembly my front camshaft seems to be backwards (the one above the oil filter) Got my engine on top dead center 1/1 and the gear can only go on to the cam backwards. I can’t turn the cam using it’s bolt more then a quarter turn and then it stops with half the springs compressed. Markings on my timing gear are upside-down so I’m assuming that won’t work. The other head cam turns freely by hand for about a quarter turn and if I use the bolt to turn it I can get it to rotate all the way around so that one seems alright. So what do you guys think is the problem? I have to get a new cam as I put on too much force trying to turn the cam and broke of the bolt head inside the cam.. But would a new cam fix my problem? Need to get it rotated 180 degrees for the lines on the timing gear to be level with the piston head.

Sorry for the wall of text. Can post pics if I have to but I’m hoping I explained clearly enough. Thanks
