The Porter-Cable 7518 is one of the classic large production-router motors used in router tables. It is especially useful for compatibility research because several major lift manufacturers explicitly design around its approximately 4.2-inch motor diameter.
Quick answer: The Kreg PRS5000, JessEm Mast-R-Lift II, and Rockler Pro Lift are all manufacturer verified for the Porter-Cable 7518 in WoodToolGuide’s current database. The JessEm Rout-R-Lift II remains Unverified because its published model-specific list does not include the 7518.

Why the Porter-Cable 7518 is a reference motor for large lifts
The 7518 belongs to Porter-Cable’s 7500-series router family. Porter-Cable documentation identifies the 7518 as a fixed-base production router and the 75182 as its replacement motor. Current service documentation lists variable speed from approximately 10,000 to 21,000 RPM and describes the router as suitable for table or machining-station use.
For lift fitment, the important number is the motor body size. Kreg and JessEm identify the 7518 at approximately 4.2 inches, and Rockler uses the same class as the direct-fit size for its Pro Lift.
Kreg PRS5000: verified, hole pattern 1
The Kreg PRS5000 manual places the Porter-Cable 7518 at the top of its clamp-block table: 4.2-inch motor diameter, hole pattern 1. This is a direct manufacturer setup instruction and requires no adapter assumption.
JessEm Mast-R-Lift II: verified 4.2-inch fit
JessEm’s current Mast-R-Lift II page groups the Porter-Cable 7518 with its compatible 4.2-inch motors. That makes the 7518 one of the lift’s explicitly supported large-router options.
Rockler Pro Lift: verified direct fit
Rockler is particularly clear: its Pro Lift fits full-size 4.2-inch router motors without an adapter collar, and the Porter-Cable 7518 is explicitly listed. The optional 3-1/2-inch collar is intended for smaller named motors such as Bosch 1617, DeWalt DW618 and Porter-Cable 690/890.
This distinction is important when shopping. A 7518 owner should not buy the 3-1/2-inch collar assuming it is required for the Pro Lift; Rockler documents the 7518 as a direct-fit motor.
JessEm Rout-R-Lift II: why it is different
The Rout-R-Lift II is not simply a cheaper Mast-R-Lift II with the same motor range. JessEm sells it in versions for selected router families: PC 690/890 and several 3.5-inch routers, Makita 1101, Hitachi M12VC/KM12VC, Milwaukee 5615/5616/5619 and RIDGID 29302. The Porter-Cable 7518 is not on that published list.
Therefore, despite the 7518 being compatible with the JessEm Mast-R-Lift II, WoodToolGuide does not transfer that compatibility claim to the Rout-R-Lift II.
7518 versus 75182: do not confuse router and replacement motor numbers
Porter-Cable documentation distinguishes the complete router model 7518 from replacement motor model 75182. Lift manufacturers normally list “Porter-Cable 7518” as the compatibility reference. When buying used equipment, verify what motor you actually have and compare the housing to current manufacturer documentation.
Buying checklist for a Porter-Cable 7518 lift
- For Kreg PRS5000, configure the clamp blocks to hole pattern 1.
- JessEm Mast-R-Lift II is explicitly listed for the 7518.
- Rockler Pro Lift accepts the 7518 directly; its 3-1/2-inch adapter collar is not required for this motor.
- Do not assume JessEm Rout-R-Lift II compatibility just because the Mast-R-Lift II supports the 7518.
- Check lift-plate dimensions separately from motor compatibility.
Bottom line
The Porter-Cable 7518 is one of the best-documented large-router motors for lift use. Kreg PRS5000, JessEm Mast-R-Lift II and Rockler Pro Lift all explicitly support it. The JessEm Rout-R-Lift II is a different, model-specific product and remains Unverified for the 7518 in WoodToolGuide’s current database.
