Manual tire changer help

[Mysfyt]

About the recessed part of the rim being up, yes I found that out the hard way.

Do you put that hook over the edge of the rim like the picture below? If you do, how do you keep the hook down around the rim instead of just riding up and off the rim when it hits the tire. It starts doing it when the tire starts getting tight.

My dad had the same machine at his gas station, only it had an air operated bead breaker on the bottom. Maybe its the picture, but the hook for rolling the tire back on looks too blunt on the edge where it will meet the tire. I remember that edge being tapered and very smooth, for obvious reasons.

A spray bottle with soapy water does wonders

I saw a couple u-tube videos and after they soaped it up really good, they just pushed the first bead on with their hands. Looks like I am not using enough soap also.

I have the harbor freight version- it works ok- I avoid using soapy water because some will get trapped inside the tire and I figure that it may lead to additional rust on the rim. I have a bottle of armor all that I use to lube the bead.

Is my fear of using soapy water (because of corrosion) valid or am I just overthinking it?

I use a mixture of dish soap and water to lube the tire bead before installing. Dish soap also shows any rim leaks after blowing up the tire.

KYErik if you're concerned about corrosion here's a lube that has anti corrosion added to it for that purpose.

George2615 that's what I use too. Dish soap and water slopped on with a cheap paint brush. I do try to keep it just on the bead and not so much to fill the tire up.

franklin2 I seem to have the same problem as you. I have to hold back on the bar to keep it on the rim while tapping it around. Sometimes I just grab a tire tool and put it on.

Umm -actually that's a picture of mine , not the ops and overall it works well.

Have used it twice a year to switch between hiway/snow tires on my Ram 3500s 17 inch ten plys.
15 inch car tires are a breeze.


Not sure if the OP has got his machine and bar working well together yet.

Yes, I did steal the pictures, they came up on google images. Thanks for putting them up. I haven't had a chance yet to try all the ideas. What I have been doing is taking a large screwdriver and a couple of prys and the tire pops right on. But I felt like I was "cheating", I want to be able to do with the machine. Thanks for everyone's help so far.

Never had a bar with the wheels, but my guess would be the wheels ride the rim, not the tire bead; but, I have never used that type.

So, you just push your lubed first bead, the lower one, onto the rim without the tool. On the upper bead, where ever you get the mount bar started, let us call that 12:00 and you will be going clockwise with the bar. BEFORE starting to rotate the bar, push the tire sidewall down into the drop center at about 10:00 or so and put a chock of 3/4" wood there to hold it, continue with your hands pushing the tire down into drop center and placing wood chocks as you go as far as you can, which will be about 7 or 6 o'clock. Then use your hip against the bar to push it clockwise with your right hand on the bar close to the mount tip pulling in to the center of the rim and pushing down. Heavy duty tires or run flats will kick your butt and require several tire spoons to finish. I still use a manual machine, but I found a far better bar, called the MoJo Lever. Google is your friend.

I thought the little wheel went against the rim too, but it doesn't work well at all like that. The "take it off" end of the bar works beautifully when the wheel is pointed up against the tire. I haven't seen the wheel on the "put it on" side of the bar really do anything.

No- the hook slides on the outside of the rims lip
The wheel rolls on the tires inner bead as the bar is pulled against the tire machines center post .

When working correctly the bead slips over the rim behind the wheel as the bar is moved around the wheel


If I get a chance I will take a few pictures of my changer with the bar putting a bead on.




ps. Here is a place you can get a parts/operation manual for the old Coats machines- Very helpful...


Coats Tire Changer parts Manuals



Page 3 of the 510 manual shows the mounting procedure using the bar in question (although the manual itself is upside down) that should clear up some things

The mojo lever looks to be handy -but it's $109 also mentions only motorcycle tires- edit Looks good for motorcycle tires


but
1st thing stated in it's manual- (CAUTION: The Mojolever is a heavy tool and may cause injury if dropped or broken during use.)

and then this:

( The Mojolever is intended for use on motorcycle tires only. Do not attempt to use the Mojolever to remove or
install automotive tires.)

That makes it a non starter for car and truck tires.

Not sure whether a bike tire could be changed on one of these old Coats machines- but with the large diameter of the center shaft it looks like the wheel centers would not fit over the machine.?



but no reason the original bar shouldn't be able to be made to work.
