I recently removed the left 3 wheels on my Genie and cleaned the area around the belt, as my geysers aren't spitting enough water.. it seems.  That's a topic for a different day I suppose, as I'm making do.

But when I re-attached the 3 wheels, and began grinding once again, I am having a problem with the 3rd wheel.   It's ''slipping'' - it's ''loose'' -- when I push the cab against it, the wheel slows down and quickly stops-- i can actually hold my fingers against it and it will come to a stop.

After removing the wheels, I notice the first 2 wheels are very difficult to slide off.. there's some sort of texture on the inside of the wheel.. the part that makes contact with the arbor, that's causing enough friction to keep the wheel firmly in place (on the first 2 wheels), but on the 3rd wheel, it's slick and clean.. I must have wiped whatever residue that was on there out with a rag.. which unfortunately removed the friction-causing material, which now results in a loose wheel.

What can i do to resolve this?

I've already tried tightening the bolt back on extra tight.. and i fear tightening it too much further as to avoid damaging.. but it seems to me there's some sort of glue-like substance I should apply to the interior of the wheel, to re-create the initial texture that was on there before I slid the wheels off.

Thanks!

If its an older genie then you need to tighten it some more as the tightness/friction of the wheels is what turns the pulley that operates your pump. The newer genies have gone a different way but I have not seen one to know what it is yet.

thanks, i'll give that a shot-- it's definitely an older model.. i would guess at least 7+ years old

I haven't worked on much of genie's, but on older machines from the 60/70's ive used teflon tape or contact cement in the area before setting the wheel and washers down tight. You still may need to true up any wobble but it adds a little bit of material to fill that .03mm void your arbor may have. I've come into a lot of older machines, specially stuff that still have old corundum wheels on them and sat for a decade, have a lot of wear where the wheel has sat, and usually tough to get a solid fit without cranking down on the arbor nut. Or Frantoms that just use lock-collars... anyways. Another technique was cutting rubber or cork(your choice) gaskets to sit between the wheel washers and the wheel.

So after tightening further, it only begins to unwind the other side... doesnt allow me to ''over-tighten''

The wheel is now noticeably LOOSE.  I can feel it wiggle slightly when I push it side to side.  The knocking noise you hear in the beginning is the wheel jiggling side to side.

Here's a VIDEO --

Ok I've tried the teflon tape method- and it was too thick of a material, as the wheel caused the tape to just bunch up and slide over.

I'll now head to home depot and grab some contact cement and give that a shot.  Not familiar with this material so I hope to not to cause any further issues.

Here's another video I took to demonstrate the ease of sliding i'm currently dealing with. You can see from the video that it slides really easily from right to left until it gets to the part of the arbor (is the metal pipe the wheels slide onto called an ''arbor''?) - and once it hits the part where the other wheels are seated, there's a residual gum of some sort that causes enough friction to keep the left-most 2 wheels in place / operational.  Once the wheel slides to the left and makes contact with that area, I had to push hard to get the wheel to slide back to the right where the ''loose'' problem area is.

That side the wheels have to go on in a certain order and facing a certain direction to make it work, when you have it correct the spacing will be even between all 3 wheels, right now you have a small space between the 2 Galaxy wheels (hard wheels) and a larger space between the Nova wheel (soft wheel) and the Galaxy wheel next to it. There are also two different sized spacers that have to be in the proper places, so when you get it right it should tighten up correctly. One of the wheels is not directly centered on the wheel so it has to be in the right order (I cant remember which one it is right off hand)

Also your arbor (the aluminum shaft) should be cleaned up and lightly oiled and all the wheels should slide on and off fairly easily. You can clean it up and oil it fairly easily while it is running.

You mentioned the right side loosening while tightening the left side. Been there. The solution to this part is easy.

Remove your left-side assembly from the machine. Tighten the three wheels on the shaft adapter while they're off the machine. If you have the really old Genie you might have a shaft adapter that does not have a nut on the end nearest your pump. If so, buy a new style one. It will make your life much easier. The nut on the end nearest the pump is what allows you to tighten the three wheels on the adapter while the assembly is off the machine.

Spin the right side shaft adapter with the finer grit wheels off. (Remove the entire assembly all at once.) Then get a pair of curved-jaw vise grips and a strip of thick leather. Wrap the leather around the right side shaft, hold it firmly with the vise grips, and spin the left side assembly back on. Don't over-tighten the assembly on the shaft. Snug is good enough. You'll get a feel for it. Then just spin the right side assembly back on. Again, snug is good enough.

I thought I had broken my old used machine somehow after I got it when the opposite side kept loosening up like that... .

[catmandewe]

The right side is designed to come apart as one whole unit so you can get another right hand arbor and 3 different nova wheels and you can set it up for 8,000 14,000 and 50,000 wheels which you can inter-change on and off within seconds.

Yeah. Don told me once that he has always gotten lots of calls from people who spin one side on only to have the other side loosen up.

That's when spinning the right side off and holding the bare shaft tightly while spinning the left side back on works wonders. Once the left side is snugged up, the right side will spin on and snug up normally.

Also good that you mention the 8,000/14,000/50,000 setup, Tony. For anyone who uses a Genie and hasn't added a second right-side shaft adapter, it is worth every penny.
