Marquipt wheels for stairs

[John Savage]

I didn't want to pay the huge price for a new set of wheels from Marquipt, so I purchased a set from Grainger (only $25.00 each). My problem is that the stems fit great, but the friction washer is too large. I took the washers off and there isn't quite enough friction to hold them in. The fit is so close that if I put a piece of electical tape around the stem, it won't fit....any suggestions. (please no, "you should have bought the $280.00 set from Marquipt)

JB Weld! ws

I started a thread over on the parts for sale. Read first. My newest thought, having replaced previously, is the buy just the wheel that is bolted on to the stem. Try CASTER CITY.COM. They have all kinds of wheels, including stems. I am going to be at the Miami Boat Show before making final decision.

How would I use JB Weld....I want to remove them!

 

[yachtsmanbill]

It sounded like the stems wont stay in the reciever. Did I miss something? ws

 

[John Savage]

They are suppose to stay in with the friction ring. Because the friction ring is to large, I removed them, and the fit is just not tight enough to keep them in while be used. When I use the stairs, one or two will fall out as the tide rises and falls. I need to remove them for storage of the stairs along my railing.

The snap ring are supposed to squeeze closed and just slip in the bore. If it's a matter of collapsing the ring small enough to slip in. You can use a chamfer tool in your electric drill and chamfer the leading edge of the hole providing a taper at the entrance to squeeze the ring to size. Now if the snap ring is to big for the hole, That is the ring ends meet and won't squeeze small enough to fit the bore. You can use a small cutoff wheel in a Do-more grinder and cut a little bit off the ends of the ring until it will squeeze to fit in the hole. A bit of vaseline will also help slide it in.

Thanks, Bill , I'll try it. The friction rings are much thicker than on the original set, but this should work.

I found some new wheels at HD that I am trying on my Marquipt stairs. They are polyurethane which should
wear longer than rubber. The wheels have an inner core, but the bearings are not at the shaft(bolt) they
are in the sidewall where the black hub meets the inner orange edge(see pics). The wheels are the right
width, but the hub is 1/4" too wide. You can spread the flanges on the Marquipt caster but requires a longer
bolt. I used a side grinder and wood rasp to remove the width from the hub. I'll let the group know how
well they hold up or not. No idea what the bearings are made of; saltwater will tell.

$10/each at HD.

I took one of mine off and took it to Grangers. They took the measurements and ordered new ones. The fit perfectly. Sorry I didn’t keep the ID numbers. If memory serves me I paid 18.00 each but that could be off.

Found it. These fit perfectly but I did not like the black rubber wheels and switched them out to a hard gray plastic.

 

[MadHatter53]

I got the same in black. Wasn't a fan of the hard plastic but they might wear slower.

The black rubber left black skid marks all over the dock. The ones shown on this post in red is similar to the gray ones I have.

Did these stems work? I went into a caster shop (who would have thought?) and they tracked down the original manufacturer of the Marquip set. they were custom made, and marquip owns the part.

If the stem fits with out the compression ring why not drill a 1/4" hole thru the cup, and stem and pin them with a quick disconnect?

Yes, these fit perfectly.

John,
How are those precision bearings holding up in the salt air?--I was at lowes today looking at 4 of them for my ladder--my original stainless casters are fine but the original wheel urethane tread is shot from UV cracking on all for wheels.
I've looked all over for 4in x 1/25in wheels with the simple through bolt bearing with/or without the SS sleeve, but can't find.

Have a brother in law that is a machinist. Turn the caster shaft down or bore the ladder wheel receiver.

The tricky part is getting the old ones out. Ours were frozen in and eventually I bolted in new stainless ones after cutting out the old ones and their carrier tubes then building up from the bottom step to accept the caster platform.

i drilled a hole above the caster and beat it out. The other three came out easy. My dock was a mess after a weekend using my stairs with the new wheels so at some point will need to swap out the black rubber wheels with something else. My stairs are rarely used so it’s no big deal. I thought about getting a sheet of SS and attach to the dock where the wheels touch.

The “red”wheels I mentioned 15 months ago have held up well and no problems with the bearings.
