ADJUSTING CRANK FOR SAT DISH

Post by RGORJANCE » Sat May 13, 2017 6:25 am

Having a posible senior moment today. Does anyone know the brand name/source for those hand crank sat adjusting thingys? We had one go bad. I don't remember the brand of the dish (abt 3 meter). They look kinda like the boat trailer crank-up/down wheel devices I used to have with the folding handle.

Any suggestions would be great.

Thanks,

Fossil

It is called an actuator, and DawnCo still sells them.

Actuator or Jack. If you find a manual / crank polar jack let me know where...

I have been custom building jacks out of large all-thread and a few pieces of angle. A couple we just drilled holes and used jam nuts and on a couple that I knew were frozen beforehand, I carried my motor welder and welded up a replacement onsite.

I don't think that I have taken a single picture of any of what we built.

I had called a couple of TVRO dish venders and none of them had cranks in stock so I just built them myself. The only problem that I have ran into is that various dishes seem to require widely varying lengths. All-thread is commonly available in 36in lengths and on one we were literally on the last thread of a full 36in stick. Others are typically less than 36 on one side of the dish or the other.

Dale and I must have hit send at the same time...

Back in Feb, I called Dawnco and was told that they had motorized actuators but didn't have crank types.

Have you talked to a specific person?

No, it has probably been a decade since I last ordered an actuator.

I has been many years for me as well and it was a crank type but it came from a local TVRO dealer.

The last TVRO dealer in my town was also a vendor for one of the small-satellite-dish systems (I disremember if it was Dish or DirecTV) and expanded into other home entertainment equipment. They have moved, but I have emailed them to see if they have any of the old hardware. Fossil could check with local Dish/DirecTV vendors to see if any of then still have leftover relics from the "West Virginia state flower" days.

Well, it looks like I came up with-------at least an idea.

Got to thinking about the issue and like being hit by lightning, there was this flash out of the blue! , I remembered the hand crank trailer jack that was on a boat trailer I had a lot of years ago.

Got to looking up trailer jacks on the net, and they have a HUGE variety to choose from, and everything in our size is well under $100.00. There are a bunch that are not equipped with wheels, and some of them even had plates on the end. There are round ones and square ones. Weight ratings ratings ran from 10,000 pounds to 2,000 lbs. I just have to think that these critters are going to be perfect. Throw length seems to be around 10 inches, and the jack might have to be roughed in to an approximate position to kind og center it up before securing the clamp. That then gives +/- 5 inches of travel. Thinking out loud, that's probable plenty. I''ll go to the dish site on Monday and size things up.

Hope this wild idea stirs up some additional ideas from the group.

Lacking a direct bolt on solution, I will probably just build another couple of my all-thread concoctions. I have a confirmed frozen crank to inspect and measure Monday and will get it fabricated and moved in the next couple of weeks.

Then I am off to a 3 tower AM ground system rebuild... Lots of fun this summer.
