Kwikee steps - that plastic gear issue 1991 250

Hi - my steps are still not fully functional. I've done a fair amount of research, bought a replace Taurus window motor, which fitted fine. Steps still not working.

Can anyone confirm a source for the plastic gear mechanism which is prone to failure in these steps? I am assuming it is within the gear linkage. I'd rather not buy the entire linkage set, so any leads on just the plastic gear mechanism would be greatly appreciated.

Thanks
All
Nick

Nick,

Do you remember the brand and part number for the step motor that you purchased?

John will be jumping on this thread soon as well. His steps opened out but didn't lock; upon stepping on the last step the step started folding back up taking his foot with it. Luckily he managed to extricate himself before he face planted into the concrete sidewalk.

The motor he took out certainly is a power window regulator for something, but he's not convinced it's the motor yet; further testing required.

Dropped by his place on Saturday; three new LED headlamps working but only getting 9.3 volts to drivers side high beam. He wasn't a happy camper.

Cheers
Tony

Had the same problem when we were in Lancaster, PA last summer, I unbolted the whole unit (2) step , ordered a new (3) step unit (the 370LE sits 10Ē higher than the other classics) re wired them correctly, the previous owners had combed them up terribly....and now all is good, Regards, Bob

Step Motor was Dorman 742-206. Apparently, the 742-277 is a supersession, or replacement, part number for the 742-206, which has been discontinued by Dorman. I managed to pick up the 742-206 from Rockauto for about 20 bucks. I havenít used a 742-277 so canít vouch for that, but the 742-206 bolted straight in. Simplicity itself.

For the record, I had multiple issues. Knackered motor and gearing which was caused by a faulty control module. The steps had obviously been knocked by the prior owner because the frame is slightly bent. Any binding creates voltage issues which can cause the module to switch off and steps malfunction. Those replacement modules are pricey. On occasion, you can pick up a new set of steps for circa 400 (ppl I think) which might be an option for some. Kwikee have some excellent fault finding test guides kicking about on the net. For those who have shredded plastic gears (a very common issue). They sit inside the motor. I believe they are replaceable for a few bucks but have never done that fix. Quite why plastic is used I do not know. Itís conceivable that the gearing in the motor which comes with new steps is made of metal, which would make sense and might justify the price. From memory, i think the Kwikee spare motor is made by AM equipment, so another option might be to source one direct from them.

Aren't you tempted to switch to one of the European vendors Nick?

For example Thule (the roof rack guys), make a automatic step called the Omnistep which would be a hassle to install but for which spares are widely available and cheap (in comparison).

My steps come down half way and the motor runs for about 10 seconds and stops . When the door is closed it dose the same thing but won't retract.

When the door is closed or open the steps can be pulled in or out but the will not stay locked open or closed.

They just hang half way open with no resitence either way.

For what it's worth Rockauto still has 16 of the Dorman 742-206 motors in stock for $20.79 plus shipping. I just ordered a spare for a total of $29.78 delivered.

Brad on my motor the gear sits quite a bit higher in order to mesh with the one in the gear box. Other than that it is the same

John,

Here's some pictures to work from. The first one is the Kwikee replacement. Surprisingly it doesn't even come with a gear. From the pictures it shows the gear is removable so maybe Kwikee expects you to order the gear separate from the motor!

I guess the next time I have the steps extended I'll see if the motor fits, however that won't be for a while yet.
