The wheels fell off!

Not a common topic on a boat, I know, but I suffered the indignity at the weekend of having the wheels fall off my SIB Launching wheels, that is.

Having taken lots of advice on this forum regarding launching wheels I invested 80 but the ironmongery was stainless, nice big, soft, rubber wheels, the whole lot swings up and down easily, or is easily detached if required. Perfect. Sort of.

The wheels are held on to the stub axles with washers that have a serated tooth arrangement to the internal diameter (I'm sure someone will come along and tell me what they're actually called). You put the wheel onto the axle, press the washer on and, in theory, hey presto. What's supposed to happen is that any sideways loading from the wheel causes the washer teeth to dig in and resist. Nope. Wrong. Not in this case, anyway.

The washers are not symmetrical, so they have to go on the right way as the teeth are angled along the axis of the washer. In so being, again, the theory is, easy to put on, hard to take off.

The washers are plated mild steel and the axles stainless. And there, I think, lies the problem. The mild steel teeth won't dig into the hard stainless and just slide. In 200 yards the wheels came off about 10 times The language was awful

I'm about to convert to thrust washers and Beta Clips.

Moral...check before you buy

Name of the supplier withheld whilst he decides what he's going to do about it

Codders...as an aside, this type of wheel is still the dogs

Can't you drill the axle/stub and stick an R clip through it?

Usually called "push nuts" over here.

Don't you hate when companies building "Marine Grade" hardware cut corners because they can't buy the appropriate grade of hardware, or can't be bothered to manufacture it?

Most trailer attachments fall into this category. Good stuff, until it sees salt water.

Yep, that's the plan Beta clip/R clip...all the same thing depending on where you buy it. Going for a big penny washer too to spread the thrust

Googled push nuts...seems they're more commonly called 'spider fixes' over here. Thanks

Push nuts/spider fixes...they're still useless

Mine are the same I'm going to drill and "R" clip them, also the end of the box section on the transom is far to thin so i'm going to fill it with some solid plastic section to maintain it's shape

Had the same problem with mine earlier this year - no problems (touch wood) since fitting R clips to retain them.

Mine are also made from very skinny stainless.

Cheers

Mine are the same as well. I have used all thread with a nut on either side (remove the plastic end caps from the axle) this works well, it will now be the last thing to fall off.

PS The roller bearing in the wheel also managed to fall apart.

Yep. Ditto...Shame really: for the sake of a bit of thought, drilling an extra hole and supplying an R clip, the infamous soft launching wheels get a bad press.

A classic example of he-who-designed-it-never-tried-to-use-it

Cue comment from those who bought plastic wheels
