Hard to put into 1st gear

Did you add lube into the crank hole behind the bushing? FSM say's 1/2 teaspoon I believe.
Does it grind when it goes into reverse, as in the clutch acts like it doesn't release?
A '73 FSM manual may help.......

Yes I used synthetic grease and it does not grind going into gear
