Linda,

Isn't that one of Paul’s quotes from the other day?

Isn’t everything ?

I have had to do this to two of my cameras. The others have not yet seen enough use for it to be required, and it was not required at all for my D200, which had a CCD sensor. Those sensors did not have ISO bearings, because they did not offer higher ISO options. If you do choose to do this yourself, you will find it much easier if you can purchase or rent some specialized equipment. What you will need has been around for quite some time, but may still be a little bit hard to find. Here is a description of the machine that will make the job much easier:

If you have trouble finding one of these machines, here is the original data sheet in case you would like to try to make one for yourself. Some additional detailed information can also be found on line if you undertake this project.

The original concept for the machine dates to the mid-1940s, and you will note that the data sheet is dated December 1962, so there could be some difficulty finding components. Careful observation will reveal that the data sheet is for a later, more compact model than the one represented by the drawings in the video.

There are some alternative methods to consider if you are not able to replace these bearings. Some of them can be repacked to extend their useful life somewhat, but repacking is not a permanent solution.

I am not sure how to estimate the cost to make one of these as a DIY project. If you set out to buy one, please be prepared to learn that they have held their original value very well against the initial purchase price.

Who can have a positive attitude with inferior equipment?

If you grease them regularly they will never need to be replaced.

Of Course for today!!!

A good April Fools trick (actually used on any day of the year) in the Navy was to send the junior seaman down to Supply to get a gallon of "Relative Bearing" grease for the binnacle.

For the landlubbers, an explanation is provided as a courtesy:

"A binnacle is a waist-high case or stand on the deck of a ship, generally mounted in front of the helmsman, in which navigational instruments are placed for easy and quick reference as well as to protect the delicate instruments. Its traditional purpose was to hold the ship's magnetic compass, mounted in gimbals to keep it level while the ship pitched and rolled."

Stay healthy my Friends.

A previous post mentioned "I installed a 3 amp vortex generator". That may be a solution to what ails the whole world today. The vortex generated will possibly create a worm hole and suck out the virus which is running rampant in the world as we know it. But, don't stand too close or you will be sucked into the world of ISO bearings gone bad. I sense a Noble Prize for the vortex generator idea.

I stetting this task aside for when I have more time.

I caution against waiting too long to take care of this. There is a threshold beyond which the standard maintenance procedure is no longer effective, and the entire assembly will have to be replaced. This is a much more involved and expensive operation, and it occasionally affects the ability of the camera to focus properly, leading to the requirement to recalibrate focus on each and every lens that you use with the camera. There have also been a few documented cases in which small amounts of either the lubricant or the operating medium contaminate the sensor, requiring it to be replaced a second time.

If ANYone had lingering doubts about the breadth and depth of knowledge available on this forum for the few electrons it costs to retrieve it, this thread should set them all to rest. The ability to bring Relative Bearing grease and the Triple Encabulator to bear on the same issue takes a massive amount of collaborative genius, and yet here it is on full display as just one of the many technical rabbit holes examined and illuminated. Bravo to all the experts.

You are so right!

Whilst working on the ISO Bearings, don't forget to check the Millimeter Grease in the focus reservoir!

My latest camera has the latest technology in it, so the ISO bearings are not only sealed, but self-cleaning, so they never need servicing. For my other cameras there is an obscure instruction near the back of the operator’s manual on how to service the ISO bearings. By the way, if you have to lube them, make sure to use only 5WT. synthetic camera oil. It comes from used sensors that have been recycled.
