Need help! Collar nut size?

Hey guys I just got a husaberg 501, not sure of the year but I believe it is pre- 96.. When I got the bike it was a basket case because the shift mechanism needed fixed I fixed that now on reassembly I found that the only missing nut is the flywheel collar nut.. I live in Ohio USA and their are very few parts for these bikes, let alone people who know about them.. Was wondering if anyone here could tell me what size nut that I need. Thanks in advance! Any info would help!

You could order a original factory Husaberg part from your local friendly Husqvarna dealer:
Part number: H25000501
Description: NUT POOLWHEEL 89-
Retail: $15.60


This KTM part may fit:
Year/Model: 1994,
Component: IGNITION 350-612 LC4`93
Item #: 13
Part Number: 58030002050
Description: PLUG M18X1,5
Price: $8.39


Go to your favorite hardware place and see if their M18 x 1.5 will work (left hand thread).


Find one on Amazon
