If your old Toro Z Master PTO clutch is marked 110-0449, this guide helps you check the replacement path before ordering. It covers the related Warner 5218-270, earlier Warner 5218-141, and aftermarket Xtreme X0463 references, plus the Z500 and Z528 serial ranges commonly listed for this clutch.
Toro 110-0449 PTO Clutch Replacement
Shop the aftermarket replacement for the Toro 110-0449 / Warner 5218-270 part-number path. Listed replacement specs include a 1-1/8 inch bore, 7.15 inch pulley, clockwise rotation and a pulley for 1/2 inch or 5/8 inch belts.
Check the product photos and compare your original pulley, clutch body, brake bracket and connector before you buy.
Which part numbers belong to this path?
- Toro 110-0449: the OEM number this listing is intended to replace
- Warner 5218-270: Warner lists Toro 110-0449 among its manufacturer part numbers
- Warner 5218-141: Warner explicitly says 5218-270 replaces this earlier Warner number
- Xtreme X0463: Xtreme lists Toro 110-0449 and both Warner numbers in its aftermarket coverage
Part-number tip: Warner's “replaces 5218-141” statement is more useful than treating those numbers as unrelated clutches. An aftermarket product may cover this family, but still compare its pulley and connector with the clutch on your mower.
Z Master Z500 and Z528 serial-number guide
Xtreme lists the 110-0449 replacement path for these Toro Z Master applications. The model and serial range help narrow the search; the original clutch number remains the strongest check.
| Mower | Listed serial range | What to check |
|---|---|---|
| Toro Z Master Z500 | 260000001–270999999 | Original 110-0449 or Warner number; deck and clutch configuration |
| Toro Z Master Z528 | 270000001–270999999 | Original clutch number, pulley and connector |
For a Z500 with a 52, 60 or 72 inch deck, confirm the exact Toro model number as well as the serial number. Toro uses different clutch paths across the broader Z Master family, and a serial range alone does not prove that every deck and engine configuration uses the same part.
Measurements that matter before ordering
- Bore: verify a 1-1/8 inch (1.125 inch) crankshaft, not a 1 inch shaft
- Pulley: compare its belt groove, outside diameter and offset with your original
- Rotation: confirm clockwise rotation from the pulley side
- Mount and wiring: compare the brake/anti-rotation setup and electrical connector in the product photos
Why pulley figures differ: our listed aftermarket pulley diameter is 7.15 inches, and Xtreme publishes 7.15 inches for its X0463 replacement. Warner publishes 7.39 inches as the pulley/flange outside diameter of 5218-270. These are specifications for different supplied units; confirm the intended replacement by part number and the complete physical configuration rather than demanding that the published diameters be identical.
What if the clutch label is missing?
Find the Toro model and serial number on the mower identification plate. Then photograph the old clutch from the pulley side, housing side and connector side. Include the belt groove and anti-rotation bracket. Send those details to support@ptodirectusa.com for help comparing the 110-0449 replacement with your machine.
