I'm a 40 owner with a 60 PS conversion. After adjusting the free play in my PS box, I notice a zerk in the plate that holds the adjustment screw. There is no sign of grease on the zerk but I'm assuming that's what it's there for. Am I correct in assuming that I should give it a few squirts every time I do the chassis lube? Are there any special instructions as to amount or type of grease from the 60 experts out there? Thanks.
