Tried the 50mm one but too much play. This is for the yank tow hitch to tow the SGV. You can't tighten it up either.T1 Terry wrote:Why can't you use the 50mm ball Dottie? Only a brand new coupling would be too tight for a 50mm ball and you are unlikely to have a brand new 2"coupling these days
There you go.....you need a 2 inch ball.....The correct equipment is at the heart of the matter. The hitch ball on the two unit must not only be the correct physical size to match the trailer hitch, but needs to be able to tote the weight of the trailer. There are three different sizes of hitch balls, 1 7/8", 2", and 2 5/16".
The smallest might be found on a lightweight pop-up trailer; the 2" are typically used on mid-sized trailers, and the largest--well, sure enough, on large trailers. The large size hitch balls have different weight capacities, and you need to be sure the capacity of the ball is greater than the total weight of your loaded trailer. You MUST match the size of the hitch ball on your tow rig to the size required by the coupler. Go with too small a hitch ball is to invite a disaster.
Hitch balls attach to the tow vehicle with a nut and lock washer. The larger the ball, the greater the torque required for a safe attachment. The hitch ball mounts through a drawbar and the thickness of the drawbar determines how long the shank, or threaded portion of the hitchball, needs to be. Rule of thumb: At least one thread should be visible beneath the lockwasher and nut when the ball in installed in the drawbar.
When installing a hitchball the philosophy of "just throw a wrench on it and tug" isn't a safe one. If in doubt, have a hitch shop attach your tow ball. Trailer couplers need to be kept lubricated with grease. We prefer lithium grease, and we keep our hitch ball greased and we cover it with a ball cover when not in use.
