I need some help with anyone familiar with common issues with hard shifting on a 2003 Honda TRX350TM. I had some issues that progressed from hard shifting to the shifter not springing back to the middle position to the bike not wanting to shift into any gear beyond first. I have the engine out of the ATV and both the front and rear crankcase covers removed. The symptoms and steps I’ve taken are listed below.
•Hard shifting
•Rolling forward while idling in gear
•Attempted to adjust clutch
oFound jam nut seized
oUsed penetrating oil, nut splitter, and impact gun to remove
oCleaned male threads, applied anti-seize, and installed stainless 8 mm nut
•Difficulty shifting into the next gear
•Found shifter was not springing back to middle position
•Could shift if manually moved shifter down after shifting up and shifting up again
•Assumed shifter return spring damaged when overcompensating for hard shifting
•Removed front and rear engine cases
•Front case pushed upwards when fasteners were removed
•No damage found on the return spring
•Shifter began springing back to middle position
•Attempting to shift through gears results in normal N to 1st shift
•1st to 2nd gear shift results in cog getting hung up on point of gear instead of in valley
•Cannot progress to 2nd or make 2nd to 3rd gear shift
•1st to N and N to R found to be normal
•After continuous cycling able to get hung up and go gear point to point instead of valley to valley on 1st to 2nd
•Continuous cycling returns valley to valley shifts but still gets hung going to 2nd
