To ease greasing the Spyder front end, I followed the advice of Spongebob and purchased a LIN 5883 90 degree grease gun hose end from Lincoln Lubrication. It worked like magic on most of the nipples, but not on the upper front ones, so I ground a bit of metal off the adapter to make it fit. Photo 1 shows the upper front nipple. In photo 2, we see that when the adapter is pushed on, the corners of the adapter contact the metal of the Spyder frame. This prevents the knob on the nipple from riding all the way up the ramp and into the detent, see photo 3. Photo 4 shows the solution, the leading edge of the adapter is ground away just enough to allow the nipple to enter the detent. ( note: the photos are not in order, check the numbers in the upper left corners).
