When your RV slide room starts grinding, skipping, or refusing to extend fully, a worn or broken spur gear inside the slide pack assembly is often the culprit. This Lippert 700612 replacement spur gear is the correct OEM-spec part for standard 2.5" x 2.5" inner-rail gear pack assemblies. Get the exact tooth count, pitch, and pressure angle right the first time and restore smooth slide operation without replacing the entire pack.
Lippert slide-out systems rely on precision-cut spur gears to translate motor torque into the linear movement that extends and retracts your slide room. Over time -- especially with infrequent lubrication or debris intrusion -- gear teeth wear flat or chip, causing the room to hesitate, bind, or fail to move at all. Replacing just the damaged spur gear is the most cost-effective repair path when the rest of the assembly is still in good condition.
Part number 700612 (vendor part 07-7583) is a direct-fit replacement for several Lippert standard gear pack assemblies. The 15-tooth count and standard 10-pitch, 20-degree pressure angle match the original factory specification, so no modification or shimming is needed during installation.
Matches the OEM tooth count exactly for proper gear mesh with the rack and mating gears in standard Lippert slide packs.
Standard spur gear specification ensures correct tooth engagement and load distribution across compatible assemblies.
FX-1008-50 copper-infiltrated sintered material provides strength, wear resistance, and self-lubricating properties suited to slide-out duty cycles.
Confirmed fitment across five Lippert assembly part numbers without modification. No adapters or custom machining needed.
This gear is manufactured to FX-1008-50 copper-infiltrated sintered iron specification. Copper infiltration fills the porous structure of the sintered base material, improving density, strength, and the ability to retain lubricant within the gear body. The result is a component that tolerates the intermittent, high-load demands of a slide-out mechanism better than plain sintered iron alternatives.
For best service life, apply a fresh coat of Lippert-approved slide gear lubricant during installation and inspect the rack and pinion engagement before closing the assembly up.
Lippert part number 700612 is confirmed to fit the following Lippert gear pack assembly part numbers:
The 2.5" x 2.5" measurement refers to the inner rail dimensions of the slide pack housing, not the overall exterior size. Verify your assembly part number against this list before ordering.
Replacing a spur gear in a Lippert standard slide pack requires disassembling the gear pack housing. The work is within reach of a mechanically confident DIYer with basic hand tools, but the slide room must be fully retracted and the motor disconnected before beginning.
