On my pontoon lift, I have black pipe shackled to the frame and slip on with pin to prevent walking
The hub on PlayStar's dock wheel fits 1 5/8" or 1 7/8" pipe. We recommend also using PlayStar Dock Axle Kit PS 1198. Any additional questions please let us know. 1-888-PLAYSTAR (752-9782).
We do not have any parts that will address this issue. A suggestion would be to find pipe that is greater than 1" inside diameter and less than 1 5/8" outside diameter cut to length to insert inside the dock wheel hub. Any additional questions please let us know. We can be contacted at 1-888-PLAYSTAR (752-9782). You will be immediately greeted by a real live voice.
What size and type of pipe do you have to use for the Hewitt roll a dock axel to make this wheel work?
The hub is six inches wide so plan on an axle at least seven inches.
I used some u-clamps that i bought at Home Depot. I think they were $2 each and I put two on each end of the axle which I mounted to wood
The hole is 1 7/8" and 9" deep. (the outside diameter of 1 1/2" Sch 40 PVC pipe is 1 7/8" ) but don't use it for an axle. I have them on a 12" long axle with a 2" washer and cotter pin on each side.
