Eastern ND | I think they are a 3/8 allen wrench. To loosen them, pull wrench forward at the bottom. To tighten, pull wrench rearward at the bottom. There is a RH thread, and a LH thread so be sure to get the correct ones. To remove the plug, put a vise grip plier on the disc very tight so You can keep the disc from turning. Then use a GOOD 9/16 wrench to remove the plug. ALWAYS put new plugs in whenever You take them out. Damn hard to remove the plug when they are all rounded off. | |
