Repairing a damaged lower timing cog:
Now I’m going to have to change some direction here, as I ran into a minor problem with my timing cog setscrews.
Later series 700’s used 3/32 Allen screws, while some of the earlier models used 5/56ths. See figure 15 for timing
screws. And sometimes you may find that one of the setscrews has been rounded out, and your Allen wrench will not
loosen the screw. This is where the Moto tool is a must. Using the cutting wheel, I cut a screwdriver slot into the screw,
as well as part of the cog. That’s ok, at least I have a slot in the screw now that will allow me to extract it. You may find
that you will need to use a small hammer and small punch to tap the little
bugger loose with. Using a screwdriver doesn’t always work, even though
you have the slot cut into it. Once it’s loose, go ahead and remove it and
throw it away. We’re going to have to drill and tap the cog for 3/32
setscrews. To repair this, we’ll need to remove the motor, and get the cog out
of the machine. This will all be continued, and I’ll redo the timing belt in the
beginning of that section as well. Cleaning up a document this intense,
meaning file size and such, is just more than I can handle right now. Either
way, I hope your enjoying this manual so far. Please bear in mind, it is my
first in a series, and I’ve learned quite a bit more on how I should assemble
something of this nature.
Please refer to the next section, 700SeriesRepairS2
, for the rest of this manual.

Terry
