You are looking at a Pro-tek SWING ARM BUDDY repair kit that replaces a chain adjuster bolt after it seizes or breaks off in the swing arm of most off road motorcycles.During normal cleaning and/or operating in moist environments, water enters and migrates to the rear of the swing arm causing the bolt to rust and seize. Consequently, at the next chain adjustment interval, the bolt can break off in the swing arm. This is becoming an increasingly common problem with today's motocross, street and enduro bikes.Rather than removing the swing arm from the bike, the SWING ARM BUDDY allows the average rider to fix the broken stud in approximately 10 minutes without the expense of a machine shop, normally required for this repair.It comes with a high-speed hardened drill bit used to drill out the broken bolt. You then permanently insert the stainless steel threaded block. With threads replaced, a new adjustment bolt and lock can now be used. And because we use stainless steel, binding and seizing do not occur , so next time the bolt wears down, simply screw another one in. Its that simple.NOTE: Because we are drilling out the broken bolt, the new bolt will have a larger head than the stock chain adjuster bolt. You will now use a 1/2" or 13mm socket instead of the stock 13/32" or 10mm socketIt comes in five distinct kits containing one 3/8" extractor drill bit and 1-5 special thread fittings. Instructions are also supplied.These kits are brand new, still in original packaging with manufacturer warranty. These are American made kits from a name you can trust- Pro-tek- a leader in the motorcycle industry for over 30 years.Applications:1988 KTM 500 MXC1989 KTM 500 DXC1990 KTM 500 EXC1992 KTM 500 EXC2012-2016 KTM 500 EXC1988-1992 KTM 500 LC41985-1993 KTM 500 MX2012-2016 KTM 500 XC-W
