When we went camping the other day are top would not go down because the crank would not turn. In desperation, I sprayed a bunch of WD-40 into the crankshaft to see if it would help. Eventually I took the bottom shield off of the Whiffle tree and found that the first few inches of the rod were caked in old grease. We sprayed it heavily with WD-40 and got the crank turning and sprayed it as I lifted the top up and down. However, I feel like I need to go back and clean that first few inches better and I'm wondering what the best way is to do that? I am also wondering if I take the outside case off of the crankshaft will that release the spring or any other parts or will it just leave the drive shaft? I want to clean the drive shaft and the whiffletree but I don't want to have to reassemble the whole system.
