[TowerTalk] TB3 Bolts

[Tim Duffy K3LR]

Hello Tom!

There are 4 bolts on the Rohn TB-3 that attach it to the top tower plate.

The galvanized bolts are 0.500" in diameter - the nuts are 0.750" and the
bolt head is 0.875". They are 1.5" long. The as drilled holes in the bearing
mount are 0.59375" in diameter.

The three horizontal bolts that secure the mast are 0.375" diameter.

73,
Tim K3LR

Hello

 

Does anybody know the size of the bolts that connect a TB3 thrust
bearing to the top of the tower.

 

Thanks for your help
