Yes, sidemounts are easily removed without removing the hood. BUT please use this procedure to save headache: 1) You have a 1" or so teardrop shaped flywheel site hole cover on right side of your clutch housing. Find it, loosen the screw and slide cover outta the way. 2) SWITCH OFF, tractor in neutral, MANUALLY rotate engine around to just before #1 TDC. As you approach TDC, look thru the site hole at the flywheel. The flywheel has your static timing marks. If your flywheel is not one of the many dumb aftermarket ones (i.e., an original), you will see the stationary needle (inside and attached to housing) point at the various flywheel marks. At 4% BEFORE TDC, that is the proper static timing. If you have a screwy flywheel, roll #1 to TDC and counter-rotate engine back about 4" of travel using a 10" socket wrench (i.e., the end of your socket wrench will travel 4" in its arc). Whether original or screwy flywheel, MARK the spot that the pointer is pointing to on your flywheel with a grease pencil so's you can see it more clearly when reinstalling the dist. 3) While at proper timing mark, pop the dist cap off and verify that rotor is pointing almost right on #1 dist wire. If it's 180% out, you aren't at #1 TDC compression stroke. Redo above procedure. If you are, gease pencil the rotor position on the METAL HOUSING of your dist so that you can line it back up durig installation. 4) Loosen dist advance clamp and hold-down screws and pull dist straight out. May require a good yank. 5) Replace bushing exactly as you have correctly inerpreted your manual. While at it check eccentric gear at bottom of piston for chipping (can happen with really bad bushing problem). 6) To reinstall dist, rotate the rotor to about 1.5" clockwise (I think) and reinsert dist back into dist hole. The eccentric gear will cause the rotor to spin. You want the rotor to spin exactly to match the grease mark on the metal part of your dist housing and you may have to pull dist back out and keep retrying until it does. 7) After reinstallation and grese mark matching, tighten clamp and hold-down screws and recheck both metal housing mark and flywheel marks. Check plug wires to make sure they haven't come loose in the dist.
