Is there a way to repair window cranks?

Our 1974 Ventura has defective cranks on all windows. It is getting a bit tiring to have to go outside to push the windows shut each time.

Is anyone here able to tell me if these window cranks can be repaired, or replaced ?

Maybe someone can point me to a relevant thread, in case this has been discussed before.

The crank mechanisms are available but there are different styles. I got one for our teardrop at our local Ace Hardware store. I think Camping World has them. Better to buy it local if you can to compare with what you have. Replacement handles of different lengths are available too. Bob

On this old house tom used a wad of steel wool wrapped around the crank . He then put the handle back on with the set screw.

The gearboxes are worn or stripped internally. I got lucky and found some new old stock gearboxes at an old RV supply in California. There are lots of variables to watch out for, e.g., left or right, shaft diameter and depth, box size and shape.

But some are still out there somewhere...it also takes a bit of patience to install them.

Mobile homes use those type windows and someone told me the parts are very common in Florida where that type of window was used on many houses. Have seen some parts at our local Ace Hardware too. Even if they don't have your part the parts they have might give you a manufacturer as a source.

Is it the operators or the crank (handle)? You might try this, it's a huge catalog, over 200 pages: GO-RV.com - RV On-line Catalog.

There are operators about 1/4 down this page: Interstate RV Metal & Supply

or here: Window Hardware

Good luck

The Ventura window operators are the same as the Boler.

Boler Torque Bar Window Operator

There was a thread on here somewhere that showed how to change them from inside by cutting and bending the frame (how I did it) but after looking at them, I would open the windows and remove the bottom panes by removing the screws on the sides of the pane frames. This should give you access to the operators. If you do used the cut and bend method , remember to use some caulking to seal the frame so no water gets in .

Vintage Trailer Supply - parts and supplies for vintage travel trailers and campers! has alot of the seals for windows and other stuff for these old beasts and shipping isn't too bad( they also have key blanks for the bergmann door locks)

The part numbers for the operators are:
1718C Right Hand
1719C Left Hand
They come with the 11/16" hub projection the Ventura windows require.

All but one of ours failed (and were replaced) in the last couple of years. I think I'll replace the last one before it fails while on the road.

Fortunately they're not quite made out of unobtanium yet. Although I don't know if they're still produced or if all that's available are NOS (new old stock).

Please let me know where you buy yours from. Cheers!

Darrell How did you replace them is the question. I got a few cranks, and now I'm stumped on how to get the old ones out without destroying the window
