FAQ
Does this PTO clutch replace Bad Boy 070-5035-00?
Yes. This aftermarket clutch is offered as a replacement for Bad Boy 070-5035-00 on supported applications. Match your original clutch number and physical configuration before ordering.
Does this fit every Bad Boy AOS mower?
No. This listing covers AOS configurations specifying 070-5035-00. Check the parts manual for your mower’s production year, model, and serial number, then compare the original clutch and mounting arrangement.
Is Warner 5218-219 a cross-reference for 070-5035-00?
Yes. Warner lists 070-5035-00 among the manufacturer part numbers associated with its 5218-219 clutch.
Why do some reference specifications list a 6.3-inch pulley?
Warner lists a 6.31-inch outside diameter for its 5218-219 clutch. The aftermarket unit offered here has a measured outside diameter of approximately 6.125 inches.
Outside diameter and the working diameter where the belt rides are different measurements. For belt speed, the critical measurement is that working diameter—not the outer flange edge. The belt groove and pulley alignment must also match the application. This aftermarket clutch is designed to replace the OEM and manufacturer part numbers listed here.
What bore size does this clutch use?
This clutch has a 1-1/8-inch crankshaft bore, also written as 1.125 inches. Match the bore and key arrangement to your original assembly.
Is this a reverse-mount clutch?
Yes. This replacement uses a reverse-mount configuration. Follow the mounting orientation and spacer arrangement specified for your mower. Product-photo orientation is not an installation diagram.
What belt should I use?
Use the OEM-specified belt for your exact mower and deck configuration. Belt width, length, and profile must suit the complete drive system.
What if my original clutch is marked 070-1000-00?
See our separate Bad Boy 070-1000-00 PTO clutch listing. Match the original part number and physical configuration rather than selecting a clutch by brand or pulley diameter alone.
Can PTO Direct USA help confirm Bad Boy fitment?
Yes. We provide fitment support before and after purchase. Email support@ptodirectusa.com with your mower model, serial number, engine information, and original clutch number. Photos of the clutch label, bore, pulley, connector, and anti-rotation connection help us compare the installation.
