Kegler Swing Arm Clamps

I have a question about installing these clamps.
I have read previous threads but have not come across my query yet.
My question is, can these be installed with the bolt heads and lock nuts at the '12 o'clock' position, the same position the locating screw is located?. I think they would be free from fouling the oil filter and mount and hoses.I have seen that some have them at the '9 o'clock' position and windy suggests the '7-8 oclock' position. My bike is completely dismantled and I am thinking it may be easier if they were installed at the '12 o'clock' position. Would they foul anything?

You could mount them in that position, but they wouldn't do the job intended as they are designed to prevent axial movement of the S/A pin.

Thanks for your advice acadian. That certainly makes sense.

Hi Changaroo,
You could mount the Kegler clamp locating bolts (no nuts needed) at 12 o’clock position without fouling the oil filter/mount and hoses however at this position the bolts will not support the spindle for lateral forces. Maximum support is achieved at 9 o’clock position of the locating bolts (no fouling either). Also I recommend using only steel Kegler clamps (like original) because aluminium clamps will deform unless you make them a lot beefier (which then will result in fouling aforementioned parts).
Good luck,

On my Commando I did a little variation on the Kegler clamp theme. I discovered while installing the clamps without the set screw that just the clamps alone would tighten down on the spindle. My spindle bore was still in good shape, however, if the spindle bore is worn you should get an oversized spindle. I temporarily installed the clamps as far outboard as possible and in that position I marked location slots. I had to file away some weld spatter to get the clamps in the desired position. Then I removed the clamps and cut the slots in the spindle tube at the location points. I then drilled 1/8 inch hole on each end of the slots as a stress reliever.

Once the clamps are installed they positively lock the spindle in place. I am coming on 10,000 miles after this mod and the spindle is still tight in the spindle bore. I went this route because it makes a cleaner looking installation as one reason and the spindle is clamped a full 360 degrees. Also I don't have to be concerned about a set screw damaging the spindle itself which would make the spindle difficult to remove at a later date.

Another thing I had to do was grind away a portion of the right hand collar clamp to get clearance for the outboard oil hose. Here is a picture of the collar clamp installed. The arrows point to the ends where I slotted the spindle tube. I also filled the slots with silicone seal.





In the picture above you may note that I modified the center spindle mounting bolt. I drilled a vent hole and then soldered a tube fitting on the top of the bolt. Later I installed a piece of tubing on the end of the bolt. This makes lubing the spindle a lot easier. Also with the spindle vented it prevents pressure build up due to temperature variations which I believe is one of the causes for leaking seals.

Thanks Holland Norton Works, yes 9 o'clock would be the best position. I have the clamps I purchased from windy, so will be putting these on.
Thanks also to Peter Joe for his unique solution. My spindle and spindle bore are both in excellent shape and I will give some thought to implementing your idea.

And tio the tubing mentioned above, I have a 30ml bottle attached upside down, and filled with 90 oil., Constant gravity feed and all you do is fill the bottle through a very small hole in the bottom from an oil can. You have to realise the oil seal set up never works properly and there is a constant slight leak, but better than a worn spindle.

ps both my Commandos have systems similar to this. You can also connect the tube to the end plate on the r/h end of the spindle as with my 750.
