Hi Dave,dave M said:Bill, I have just arrived in California for a couple of weeks and have been doing a bit of work on my own G15, could you kindly answer a couple of questions for me regarding engine mounting?
The engine plates from this bike have the various spacers welded to the plates, so it is self-evident where each one goes, however having mounted the rear plates onto the crankcases and fitted the gearbox in situ, I note that the gap between the rear engine plates is 3 5/8" whereas the distance between the forged frame mount is 3 1/2", the right side mounting plate has a couple of thin washers welded to the inside of the plates, but are there 2 loose spacers that go in the gap on the left and how thick are they?
Regarding the front mounts, there is a hollow spacer that goes between the front engine mounts at the top where it goes into the frame lugs, is there an identical spacer for the bottom mounting?
Dave, I didn't have to add any washers between the engine plates, crank case and frame. The necessary spacers were pre-welded to the plates. This is the one instance where the G15 is easier than the P11. The only spacers needed were the 3 long sleeves (2 on the front mount between the plates at the top and bottom mounts, one on the stud running through the foot pegs) and three spacers (one on the right side of the upper transmission bolt and two on the footpeg stud between the rear engine plate and the frame, thinner on left and thicker on right). The only spacers I didn't have in the bits were the two outer ones for the long, square stud that runs through the pags.dave M said:Thank you very much Bill, your measurements and spacers match what I have including gearbox mounting with top I/8th washer, I got mine as a rolling basket case with the engine and gearbox in the frame but not mounted.
Am I correct in assuming that the difference between the width of the rear frame mounting point and the gap between the plates from the thin washer, ie 3 5/8" minus 3 1/2 making 1/8th, needs two 1/8 loose spacers on the left engine plate? If this is the case I am surprised that they are not welded in place as the others are.
Hi Dave,dave M said:Bill, I am back in California and making good progress on my bike, I wanted to ask a couple of questions:
What does the front lower hole in the toolbox inner shell mount to? I have found that there is a hole in the top and one at the back that mounts to corresponding points on the frame, but it looks like the lower hole must mount to a bracket that would in turn be bolted somewhere on the frame.
The inner primary cover has three holes in close proximity to each other, one is for mounting the case to the engine/gearbox plate, the other is for the alternator wires to exit the case and the 3rd I cannot see a function, although I am inclined to seal this up to prevent primary oil going everywhere.
