Video Transcript for Review of the Replacement 18-Tooth Gear for Lippert RV Slide Out
Hello, neighbor, Steve here with etrailer.com. Thank you so much for joining me today while we take a look at this Replacement 18th Tooth Gear for your Lippert RV Slide Out. Now, in case you're not aware of what this would fit into, I put a picture up there in the middle of the screen there, so that gear there in the middle, this is what that gear is going into. Now a little close up here. Now this replaces a standard 18 tooth gear for your Lippert component slide outs. And as it says on the screen there, it will work with the LC123345 or the LC122837, if it's manufactured before October of 2013.
You do get one gear in this kit. It's just a gear replacement gear, again, 18 teeth. Very, very, very well made, high quality metal. You can kind of see the gear grooves and everything there. Not much to say about other than, you know, it's a replacement gear and like I said, it fits those components that I put on the screen a minute ago.
So this is Steve with etrailer.com. Thank you so much for joining me. I hope this information's helpful for you. Hope you get the right part the first time and should be a pretty easy replacement. So take it easy, take your time and you'll be fine.
Have a great day.

This gear slipped right onto the spindle to replace the 15 tooth gear that came on it. It works like a charm on my '04 Everest by Keystone with Lippert slides.

I have replaced this part before and wish that they made it of harder material
as it lasted only less than 10 in and out. may be an alignment problem but I will be careful with it (broken teeth)

Vicki was very knowledgeable about the part I needed and courteous and shipped it right away. I came from the sales industry and always appreciate great customer service which is something that is hard to find these days.
The spur gears were just what I needed for my slide out.

- Replacement Gear Rod for Slide-Out on a 2004 Keystone ChallengerHey Carolyn, thanks for reaching out! The pin isn't available on it's own so you'll need to get the whole Lippert 2-1/2" x 2-1/2" RV Slide-Out Standard Gear Pack Assembly # LC122837. you can either choose to keep your current 18-tooth gear, or you can replace that gear as well with the part # LC122739. I know it's not what you wanted to hear, but it's the only option available to replace your slide-out parts.
view full answer... - Solution for Needing 18 Tooth Gear Pack for 2005 Sandpiper 365RLTHey June, we have the 18 tooth gear part # LC122739 which if you need the pack too you'd need the pack part # LC123356 too and swap out the gear.
view full answer... - Replacement Slide Out Gear Pack For A 2013 Forest River Flagstaff Classic Super Lite 5th WheelYou'll measure the arm (pictured below) to determine the correct size gear pack replacement for your 2013 Forest River Flagstaff Classic Super Lite 5th Wheel Trailer's slide outs. For 2" x 2" you'll need # LC281331. For 2.5" x 2.5" you'll need # LC123356. For 2" x 3" or 3" x 3" you'll need # LC140409. Based on your picture it looks like your current gear is the 2" x 2" which comes with a 15 tooth gear so you'll need part # LC122739 to swap the gear out with to have 18 teeth.

- Correct Replacement 18 Tooth Gear for a 2010 Tiffin Allegro MotorhomeYou're correct, the Replacement Gear Pack for Lippert RV Slide-outs w/2-1/2" x 2-1/2" Arms # LC123356 uses a 15 tooth gear which is only going to work with Lippert slide outs made after October of 2013. With your motorhome being a 2010, you'd need to use the 18 tooth gear # LC122739 instead.

- 2x2 Lippert Slide-Out Gear Pack For A Slide Out Manufactured Prior To October Of 2013Since your slide out was manufactured before October of 2013, you'll need the 18 tooth gear # LC122739 along with the Lippert 2 X 2 Slide-Out Gear Pack Without Roll Pins Assembly # LC281331. The gear included with the Lippert 2 X 2 Slide-Out Gear Pack Without Roll Pins Assembly # LC281331 is a 15 tooth gear, and will not be compatible with your system, which is why # LC122739 is needed as well.

- Replacement 15-Tooth Lippert Slide Out Gear Pack For A 2009 Tiffin Allegro QBA35If the gear that you removed and was previously used was a 15 tooth gear like you suggest, then you will need to use the 15 tooth gear: -Replacement Gear Pack for Lippert RV Slide-outs w/ 2" x 2" Arm # LC281331 for the proper replacement. The 18 tooth gear will not work on your 15 tooth shaft as the number of teeth won't match and they won't be compatible because of it. Lippert does suggest that if your slide-out was manufactured before 2013, then the 18-tooth gear # LC122739 is needed...

- Solution for Needing 18 Tooth Lippert AP Gear Set # LC122837You could use the part # LC122837 but due to the age of your setup and the 18 tooth requirement what you will need as well is the part # LC122739 and you'd be set.
view full answer... - Troubleshooting Water Seeping and Wood Rot on Dutchmen Voltage Toy Hauler Slide OutOn your Dutchmen Voltage Toy Hauler there really isn't a reinforcement option to work. You really need to get to the bottom of the water seeping to fix your issue. It is common for the weather seals to be folded in at the corners and this lack of seal causing water to seep in that location and down the sides. If it is only an issue when the slide is out, then a slide-topper is the route to go. It appears this is common on your Voltage slide as many have commented and double-checking...
view full answer... - Can You Reuse Old Gears In A New Slide-Out Gear PackTechnically you could reuse your 18 tooth gear on the Lippert Components 2.5 x 2.5 Heavy Duty RV Slide-Out Gear Pack # LC123356, but if you're replacing the gear pack the gears themselves should probably also be changed. You can use the Replacement 18-Tooth Gear for Lippert RV Slide Out # LC122739 to swap the 15 tooth gears out for some 18's.
view full answer... - Correct Replacement Slide-Out Gear Pack for 2011 Forest River Sierra 300RL 5th WheelIn order to replace the slide slide-out gear pack on a 2011 Forest River Sierra 300RL 5th Wheel you'll need both the Lippert Components 2 X 2 Slide-Out Gear Pack Without Roll Pins Assembly part # LC281331 and the Replacement 18-Tooth Gear for Lippert Components RV Slide Out part # LC122739. I spoke with Lippert to confirm this for you.
view full answer... - Replacement Gear Option For Lippert Slide OutWe have a couple of options for gear packs for LCI through-frame or above-floor slide-outs, depending on a couple factors. If you have a 2-1/2" x 2-1/2" through-frame slide manufactured before October 2013, there is a gear available, the Replacement 18-Tooth Gear for Lippert RV Slide Out # LC122739. For a 2-1/2" x 2-1/2" through-frame slide manufactured after October 2013, you would need a gear pack, the Lippert Components 2.5 x 2.5 Heavy Duty RV Slide-Out Gear Pack # LC123356. For 2"...
view full answer... - Dimensions For Replacement 18-Tooth Gear for Lippert Components RV Slide Out LC122739The Replacement 18-Tooth Gear for Lippert Components RV Slide Out # LC122739 has a 0.6200 hex hub x a diameter of 1.6670 x and a height of 0.7500. If you can tell me what component the gear comes from that you're trying to replace, then I will be happy to do more research to find what you need.
view full answer... - Availability of Replacement 18 Tooth Gear Box for 2007 Keystone Laredo Slide-OutFor the Slide-Out Gear Pack # LC123356 that you referenced to have an 18 teeth gear you will simply need the Replacement 18-Tooth Gear # LC122739 as well. If you are looking for the box itself then the only way that it is available is with the 18:1 Venture Actuator Slide-Out Motor # LC132682. This comes with the motor, the gear box, and the 18 tooth gear that was referenced.
view full answer... - What Would Cause Slide Out Gears to Only Make Contact with Half of the GearWhat it sounds like is happening, is the outer tubes, are bent, or are bowing enough to where there is enough play for the inner tube to move, and skip gears. That would cause gears to strip, and pull teeth. If you can, please send me pictures of the outer tubes on each side so I can take a look, and let you know more definitively.
