Klinger 17 #1 Posted January 21, 2022 I bought a new PTO knob and of course the style changed from the original. Could someone please tell me the correct size for the PTO knob on a 1972 Raider 10. The type that was sent for a D series (I think, this is flat opposite of the thread side), mine was just a sphere. I think the thread size is 1/2 x 20.

daveoman1966 3,645 #2 Posted January 22, 2022 (edited) Here are two PTI knobs. Both are 1/2-13 threads. ..NOT 1/2-20) Large one is NEW at 1-3/4" dia ($15). Small one is USEDF at 1-3/8" dia.($10) The OEM pto knob is # 2709...probably the small one...not sure. $3.50 ship for either. Paypal as 'send money to a fdriend".

daveoman1966 3,645 #5 Posted January 22, 2022 I posted thread size at 1/2-20... WRONG. The thread size is actyally 1/2-13. The diameters are shown by my calipers in the pics... 1-3/4" and 1-3/8". Share this post Link to post Share on other sites
