i put one on my nightster, hand tight with blue locker and its been fine for along time now. may be your over tightning it and putting to much stress on the metal itself.
it is thin material.

 

on my 03 1200 xlh. dealer explained he knew someone who broke 5. been looking for a permanent and reliable replacement and have cobbed something up in the meantime which looks awful but I don't need to worry about the instruments hanging by the cables while going down the expressway. If I come upon a source/part -- something NOT made out of cast aluminum with our without chrome overcoat, will let know.

 

I have an 02 sporty and my speedo and tach mount broke at bolt holes. I know it is a common problem so I am looking to change to a single digital speedo with a tach in it. I am wondering if anyone has heard of this being changed to the new mount that is on the later gen of sporty's? And where I could get one other than HD?

 

I bought a broken mount and fixed it by welding new ears on , drilling holes and throwing some paint on it. 5 months and holding up fine.

 

Does anyone know the price of the new mounting bracket from a Harley dealership? I am suppose to go riding with my brother this weekend in Arkansas and of course today my tachometer bracket broke and I leave in the morning and of course I notice when the dealerships are all closed. I found a website that can next day air it to where we are staying but I want to know the price different between the OEM Harley part and this other one since I would have to spend more on shipping for the next day air. Thanks.

 

Tried that on my third one. Gave up and went with the side mount speedometer bracket and took the tach off.

 

For something so simple you may not bother but do you use a torque wrench?

It is bad to be loose as well as over tight. Loose will allow movement so it breaks. I guess you know that?

 

My guess is happens most on 03 and earlier XLH models where the gauges are mounted forward of the handle bars.The vibration and the center of gravity of the assembly is just to much for the bracket.

 

I had mine break on my '03 like mentioned in previous posts. I sandwiched the mount between a larger washer on top, and a piece of metal beneath the bracket, which I adhered with JB weld. That held. I also had problems keeping my highway pegs from vibrating loose. Later on I sold the bike and purchased a rubber mount model: they have more leg room, but weigh 60 lbs more.
