I would like replace all my gray tires on my Permobil M400 with black knobby pneumatic or flat free tires. The sizes are 14x3 (3.00x8) and 8x2 (200x50) for the casters. Does anyone have any good...

Okay thank you for the clarification.

Thank you. I found that site as well. Do you think the sizes on mine would at least be approximately correct even though I sanded them down some? Maybe order a little longer so I can sand them down...

Thank you. Someone mentioned I should run the motors without any load for approximately an hour to help conform the brushes since I smoothed them out or when I replace. Does that sound right to you...

First picture didn?t upload.

I wanted to post an update to my issues and let you know what fixed the problem. It turned out to be my left motor was the issue. I ended up taking it apart and it had a lot of carbon build up on the...

Okay I will ask there. Thanks

Another question if you don’t mind. I want to replace my grey tires with black ones while it is apart. What are the largest size tires I can put on the front and rear casters. They show 200x50 on the...

Okay I will replace them and see. I also removed both of the motors today and I am going to open them and look at the brushes etc. and see if anything looks bad. Thanks again.

That is my next step to replace them in the next few days when the parts arrive. I was thinking though if it is the bearings then wouldn?t it affect turning both ways and not just to the right side?...

Thanks for the idea of lifting with the tilt. I will test that out tomorrow. One of the 4 casters will swivel about 1 turn by just giving it good flip. The other 3 will not turn at all when I try to...

Okay, there is definitely quite a bit resistance on 3 of the 4 so I will start there. Thanks for all your help!

I am going to go ahead and replace the bearings to start. It looks like there are 2 bearings at each caster for a total of 8 or are there others that should be replaced as well while I am doing it?

That would be great if that is the only issue. When you say they should spin freely, do you mean there should not be any resistance to them spinning?

I could not figure out how to jack it up since my jack is pretty tall to test the motors. I will have to wait until my wife gets home with our van with the power lift for further testing on that.

...

Thanks again for the help. I will try those things. I was also wondering if I remove the motors and run them will that tell me if it is bad or not. Is there another or better way to test the motors?

Has anyone came up with any new good solutions for adding all terrain tires to there power chair? I have a Permobil M400 and would be very interested in doing this to my chair.

Thank you for the additional information. I will check that each spin freely and go from there.

Thank you for the quick replies. Yes, I will lock it from now on if I ever leave it again. I never thought grown men would do that with my chair! I will check the casters out tomorrow. Are there...

I took my power chair to my daughters wedding this weekend and left my chair there to pick up the next day. Bad mistake! Apparently some of the guys at the after party decided to start driving my...

Did anyone else watch the new webinar on the new PushTracker E2 and SwithControl? The PushTracker E2 sounds like a nice upgrade to get rid of their terrible current PushTracker watch and we can...

The following sounds like some great new features and improvements. I hope the option to use smart wearable devices mean that you can use smart watches other than theirs for controlling the unit....

Great. Yes, I agree it would be nice if they would all use stainless bolts and nuts. Thank you so much for all your help this will help me get all them replaced.

I also wanted to ask how you...

Okay great. I would prefer to use black nuts. Do they make them as rust proof?

Thanks you very much for the help.

I was wondering if any knows what size of nuts are used to install the natural-fit handrims? Mine are all rusty and I would like to replace them. Thank your for your help.
