3.5" tubeless tires

[hobie1dog]

I forgot to ask what size bolt the bearings are meant for in the wheel/tire scooter link on EBay? The stock Quickie uses a 5/16" bolt in the forks. It would be a lot easier to drill out the forks for a larger diameter bolt instead of changing out the bearings in the wheels.

[expresso]

That i cant help you with - havnt a clue myself - 5/16 is the bolt for quickie stock rims

[Burgerman]

Why do you merican persevere with old fractional measurements/sizes? We scrapped that generations ago. Its so complicated.

For what its worth, 5/16 is 7.9375 Or damned near 8mm. So close that its just 0.06 of 1 mm different. A cigarette paper or less. Which for a bolt is close enough. For a bearing not so much...

Blame it on the people who build houses, they are stuck with that system, machinists have adapted well to a numerical system. I just wanted to know what siz hole the bearings had in them.

Quickie wants $8.25 for a 5/16-24 axle bolt 4 3/4" long

[hobie1dog]

After searching around it seems like a 4 3/4" long bolt is pretty rare. But a 5" bolt should work fine.

you can work - but remember it may also stick up too high - i dont think it would stick up too high to not work - but its a chance it may - for one reason or another - i recall i returned some that were 5 inches long - since i realized it wasnt needed - to do what i was thinking of adding washers etc, but that can also work adding an extra washer on the bottom if it dosnt clear it on top with the 5 inch -

do a google search - thats how i found a site which was great and i cant seem to find it in my bookmarks now -

Non of you guys evenr cut a bolt? Screw nut on first. Put in vice (the bolt head and the nut) cut off 1/4 inch. File the sharp edges. Unscrew nut...

I do this quite regularly, works even better to touch up the cut edge on a grinder...

Worth doing in many cases, as you should NEVER have a moving part riding on threads, and it is better if the bolt shank goes almost all the way through whatever is being fastened together... So pick bolt w/ the right shank length, and trim threads to the right length...

Duh! What's a vise?

Beautiful color vise

I looked at the scooter wheel/tire/tube assembly on EBay and it states that the axle size is 10mm (3/8"), so I would have to drill out the Quickie forks from 5/16".

They generally look a bit less new!'

unless your set on getting new rims also - you can use the stock sunrise quickie rims they are plastic two pieace and this size tire fits it fine - then you wont have to drill anything -

i wouldnt be able to do that kind of work - for me its easier to get the parts that fit with no work involved - just in case you didnt know - about the stock rim
if you can find them cheap on ebay would be good - or else new its about $60 each - not cheap for one unit -

My stock rims are for the 2 inch tires. I'm going with the 3.00-4 tires. The ones on EBay are ready to go, no mounting of tires, etc. pricing them out separate is very little difference and these require no time to waste on assembly. I will likely run in to issues with the width of the wheel ( total width at the bearings) and the inside caster fork width, so I'm guessing that I will have to get bushings or washers to make up the difference.

you will need the larger forks - those wont fit in the forks that came with your chair 8 x 2 tire - thats for sure

[Burgerman]

In the UK, and most of europe, those sized wheels and tyres are extremely common. On all so called full sized, outdoor capable chairs. And in most cases black is optional too. Seems odd that its uncommon in the US considering the same companies sell the same chairs almost in both places. It must be to dowith your funding being indoor only chairs. Ours too but its flexible. So more people either buy outdoor chairs by adding cash or outright here.

i wonder if using this Rim tire setup on a quickie chair - instead of trying to drill new holes on the fork for the 10mm size - would it be possable to just change out the bearings on this rim tire combo for the correct size bolt and leave the forks alone ?

https://www.ebay.com/itm/Razor-Pocket-R ... Ciid%253A1

also on the stock rim - there is another sleave that goes thur the bearings which the 5/16 bolt slides in between -

maybe you can still use the stock bolt but without the sleave ? or change out just the bearings and use the stock sleave and bolt -

https://www.quickie-wheelchairs.com/rep ... caster-rim

number 9 - but this all comes in a set - so not cost effective -

of up find a pair on ebay - larger forks - with tires rims etc, - dont worry about the condition of the tires - all you want is the fork - and rim - should have everything you need -

Trying to remove the bearings, go buy new ones, re-install them, just to keep the stock fork holes is way too much trouble versus just drilling from 5/16 to 3/8. After the new wider forks go on the chair,with 3.00-4 tires, I don't plan on having to ever change things around. The ones you linked have the 10mm bearings in them, as that's the standard size for most scooters.

I've been looking for a stock fork/wheel and setup for months on EBay, but as you said for $33.69 each for new forks from Southwest Medical , there's no need to consider used ones ( like the P-220 forks on there now for $69.00).

[expresso]

ok i see what your saying - i guess if you can drill out the holes on the forks - would be easy and then just use those rims tires just as they arrive - may need some spacer - i only have two sets of suspension forks tires 8 x 2 since i went to fixed larger forks myself and dont see myself going back now

well i hope you get it to work and when you do - let me know how you did it - besides drilling the holes on the fork - spacers etc, -

now with those rims you found on ebay with tire - the bolt you stick thru there - do you need a sleeve also first in the rim and then the bolt slides in the sleeve ? like the orginal set up -

would it work fine without a sleeve ? i would think the sleeve helps it roll and keep it stable ? those are nice rims - compared to stock plastic ones -

No sleeve necessary, hole in forks would be 3/8" and the bearings are the same 3/8" / 10mm size, so only a spacer likely on each side of the bearings to take up the space from there to the inside of each fork like John did in his build log.

[rustyjames]

Um, a 3/8" axle will be sloppy if you plan on using it on a 10mm ID bearing. 10mm = .394 inches

take pics and post them when done - along with any parts you needed to make it work - good to know - i already have 3 sets of the original rims -

i will be adding or try to the 300-4 size again on one set and see if it clears my motors - and foot rests - if they do - they stay on the 646se chair -

I'll get a 10mm bolt then

Nice vice, but also remember the other options, like , , , etc... Not as good for getting work done, but can be more fun...

I received my two complete 3.00-4 wheel/ tire / tube assemblies from the EBay seller. 3 of the 4 wheel bearings have black seals, 1 of them has a red seal, WTF?

[Burgerman]

Throw them all away, fit stainless steel sealed bearings.

In the UK the bearings are 608 RS thats 22 x 10 x 7mm
so about £10 for a full set http://www.ebay.co.uk/itm/PREMIUM-BEARI ... 6w7F1iOKMw

Check yours for size and fit stainless steel rubber shield. Caster bearings dont wear out, these bearings get fibre and water ingress and corrode. Stainless do not... So seldom fail.

I wàs going to start changing out fork casters on my S636 but don't have a socket big enough for the top recessed nut, or a wrench big enough for the bolt head on the bottom ( bigger than a 18 mm for sure, which is the biggest I have ). Anyone know the sizes that I need to get?

Nothing is easy in this life.

if its the same as the 646se - i had to buy one also - and had to get a thin wall model - i have to check later if i can find it now - where it was placed and can let you know -

you want to know the Nut on top and the bottom under the fork - ? you have fixed forks ? the suspension forks are a bit more of a pain to get a wrench to hold that nut but with fixed - you can even try a vise grip maybe - you may have the room for that -
