Im looking for the 5 inch OD Pulley Sheave for the HDX-689. This is for the žin cable. I need to order a few of these as I'm replacing all the cables on the tower right now. I know US Towers had them

Hi Rich. I don't know how competitive they are, price wise but Heights Tower Systems does offer them. They may come up 1/2" short of your goal, though. About 3/4 of the way down the page: http://heig
According to Skip KJ6Y, the pulley's are custom made for UST. The bearing in the middle is OTS, but there is a rather involved procedure to press it in without wrecking it, then you have to make a se
I haven't had a pulley off my HDX589 but would assume the sheaves are similar since 4 of the 5 tower sections are identical to the 689. Can you post some pictures and describe what is wrong with the
Rich, I think Tashjian Towers has them, but they are expensive. Over the years I have pressed out and replaced a half dozen or so of the bearings from the pulley. They are probably K8 or KP8 bearings

Does that mean that the tower has to go back to UST to have such things installed? Just curious, before I look at spending lots of $$$$ for a tower that might need to have the same thing done a few y
NO! At worst, a local machine shop can press a new bearing into a sheave. Depending on the diameter of the sheave, your own resourcefulness and tool collection, you can often do it yourself with a la
Be careful doing that. Sometimes the grease in the bearing will catch fire. NO! At worst, a local machine shop can press a new bearing into a sheave. Depending on the diameter of the sheave, your own
If you heat a bearing to the flash point of the grease, you've probably already destroyed the bearing. 73, geo - n4ua _______________________________________________ _________________________________
There's no way I can turn the handle on my crank-up fast enough to even warm the grease! 73, George T Daughters, K6GT CU in the California QSO Party (CQP) October 5-6, 2013 _________________________

I tried calling US Tower all day...but phone just rang. Not sure if there is a holiday somewhere that they didn't come to work today. I found that the bearing inside the sheave is a K10 bearing. Look
I don't know about your freezer, but mine has never exceeded room temperature! If you heat a bearing to the flash point of the grease, you've probably already destroyed the bearing. 73, geo - n4ua Be
That is discouraging to hear. I am hoping to order some spare bearings for my HDX589. I suppose contacting US Tower wouldn't do any good, they probably wont let us know the supplier for the sheave be
Rich, I should have read your message before posting. I was going to call US Tower about the bearings too. I have a HDX589, the K10 bearings must be what I need. Now to find some !!! Bob K6UJ _______

Has anyone checked the WW Grainger catalog?? If they don't carry it, you probably don't need it. US Tower gets them from somewhere and I'll bet they are an off the shelf item. They can't sell enough
I'd be interested to know how old your HDX-589 and HDX-689 towers are, since you're both looking at doing much more than just replacing cables. Again, just looking at future expenditures in case I ge
Check out www.hubcityinc.com. They make the bearings for one of the tower manufacturers. Lots of choices, but make sure the measurements are correct. 73 Bill W6RGS At 06:20 PM 3/11/2013, Bob K6UJ wro
McMaster Carr sells pulleys. They have an assortment but from what I have seen (including the ones I bought for my HyGain HG-70D) these are not stainless steel but have some sort of plating, cadium p
