I had the opportunity this afternoon to take one of the 1025Rs, with Cozy Cab, out for the first time this afternoon to a do a little clean up. It was fairly mild here today, 25F. Well, that is mild for Minnesota in December. A little spray from the snow thrower collected on the windshield. I activated the wiper and maybe 30% of the windshield area was cleared by the wiper! What the heck? What good does all this glass do a person when you can't see through the spray film? Immediately, I noticed the wiper blade could be longer.
While I have Cozy Cabs, the wiper motors and, of course, the wiper blades are pretty generic. So this will likely apply to other brands of cabs, as well.
Back at the shop, I took some measurements and observed the wiper in action from outside the cab. The wiper blade was traveling over the head of the screw inserted through the glass to secure the wiper motor. What the heck!!! That wiper blade won't last long. I continued taking some measurements and marked out the arc of the wiper blade. I could move the blade on the motor spline so it wouldn't travel over the screw head. I performed some trail & error repositioning of the arm and adjusting the arm angle at mid point. When I moved the arm so it would not travel over the screw head, a good portion of the top left side of the windshield wasn't being cleared. That was no good.
My measurements indicated the arc of the wipe could be increased, which should resolve the clearing of the top of the windshield. I removed the cover from the wiper motor and checked the mechanism settings. It was configured for a 100 degree arc. I re-configured it for a 110 degree arc, per the following chart:
The OEM wiper blade was 16" in length. I replaced it with a 22" blade, which was as long as I could install and clear the mounting hardware drilled through the glass. It took a few more trial & error adjustments of the arm park position, at the arm to motor spline, and the arm mid-point angle. I was satisfied with the results as now the maximum amount of area, for this wiper design, is being cleared. Approximately 70%.
Below is the wiper as shipped from the factory:
Here is the wiper after re-configuration:
In my opinion, this is something Custom Products, the Cozy Cab manufacturer, should have performed during the cab build as well as supplying an appropriately sized wiper blade. Absolutely, the wiper blade shouldn't have been traveling over a screw head. I haven't checked our other Cozy Cab, but reviewing my photos of that cab, I expect to have the same issues. No doubt, this is not something a dealer would address during a cab install and nor would you expect them to.
I've had a few quality control issues with the two Cozy Cabs. While nothing earth shattering that I couldn't address, many folks don't have the skills, tools, equipment and facilities to correct these issues. At the price point of these cabs, there shouldn't be these kind of issues.
