[TowerTalk] New To ME US Towers HDX-555- advice needed

[Mike Reublin NF4L]

Mike -

If you pull the axle for the pulley, and remove the sheave, you can push a U-loop of the cable thru the housing and then put the sheave back in.

Went to Kaman bearing and bought sealed heavy duty bearings and had a machine shop bore and press the new bearings into the old sheaves.   Much less expensive than new purchase from U.S. Towers.  Went to a rigging supplier and purchased new cables.  I purchased heavy duty cable clamps for the end terminations.  The rigging company could have done the swagging cheaper but the ends would not fit through the sheave housings.  Took the tower to a welding shop and had them grind and weld 2 or 3 spots that had some small hairline cracks.  I  then went over the entire tower and put 2 coats of cold galvanizing on questionable spots.  3 coats on the thrust bearing shelf and rotor shelf.  Wire brushed thrust bearing and painted. Squeezed bearing grease into bearing until old was replaced with new.  Bought 2 collar stops to bolt to mast and rest on top of the thrust bearing.  Going to purchase a funnel to slide down the mast and cover the thrust bearing for water protection.  Have also considered a vent pipe flashing instead of funnel.
