Crusty,
Sounds like the slide in question is like the dinette slide we all have, and the street side slides that many of us have. Read threads on that “dinette slide” subject.
I too am usually in northern Florida, it currently enjoying low 90’s in New Hampshire. Much more pleasant than low 90’s in Florida but I digress.
Phil (jdpm) is correct on manufacturer of our slide components. Unfortunately Alko Kobe was bought out by Lippert and their RBW store is no longer on line for parts.
I have only very bad experience with Florida shops on my slides (Mesa in Tampa was a disgrace). Some great guys in Kansas and Fox in Elkhart Indiana but neither is close.
Skipping gears comes from one major cause. The motor mounting bolts become loose allowing excessive space between the gears that move the slide in and out. If caught early enough, you back out one or two bolts at a time, clean up threads, screw them back in to be sure the oem bolts are not 1/8 inch too long, ( in MANY cases they are and that is why they came lose!), then add and extra washer or lock washer if they are, AND blue locktite to the threads and screw back in. If only one of the 4 or 5 bolt threads in the motor itself is stripped don’t worry. If two or more are stripped, you will need to re-tap for a larger diameter bolt size or a heli-coil in the motor housing. But the less than ideal should get you through a season if you also do the prevention fix.
A few chips in the gears is no big deal if you can get the motor tightened back down again – the Alko Kobe rep told me this 9 years ago. He also told me that they told Carrige they needed to place the motor in the center of the slide not 1/3 / 2/3! The dinette forum threads I spoke of talk about bearing housing sets to prevent this from happening again. These are great, but I am not sure the guy that machined them for many of us is still active. If not, you can add a squeezed hose clamp of about 3-inch diameter to hold the two gears together. Sound hoaky, but it really works. You need a large washer and a lockpin to hold it in place, and a bit of grease to avoid too much friction but it will work and last many, many seasons IF the motor is tight.
So, good luck on finding a tech. If you give the above to a “good” tech, even one that has no experience with our slides, that good tech should be able to figure it out. Mostly labor, maybe 4-5 hours if never seen kt before; 2-3 if they have, and very little likelihood need of parts except hose clamp pieces mentioned above unless the bearing housing sets are still available.
If you are still stuck in November when I am back home, holler.
