How often do you replace ISO bearings?

Had to google it, but here's the actual grease you want!

Genuine OEM Honda Acura Shin-Etsu Silicone Grease (Single Tube) 08798-9013

Genuine Honda silicone, it will work wonders on the leaky rubber seals those little ISO bearings are hiding in!
Its really great for leaky windows and the rubber seals on the roof panels on Jeep Wranglers.. the ones that dribble 3.5 drops of water on the dash after a wash or rain, so I'm sure it's just the ticket for ISO bearings.
Only apply once a year, unless you're trekking thru a humid rainforest, that grease just doesnt wipe off! Which is kinda the point.

Not as often as you had to have ASA bearings replaced, which was once every 24 or 36 shots.

This photograph is an excellent representation of parts that are just at the point of being ready for maintenance. They are just showing some early signs of oxidation, but there is not yet any significant loss of metal.

Thanks for sharing this with us. It should help folks know when attention is needed.

The WD-40 is very good as a solvent and cleaner, but should be followed by one or the other of the two types of lubricant that have been suggested in other posts.

We've still got 45 minutes left here in Texas. This has been a fun ride.

In the absence of very advanced high-tech lubricants, synthetic oils, or suspension of microscopic ball bearing-like particles, I learned an effective substitute from my grandmother. She explained that back in the day in Poland, on the farm, they used chicken fat (schmaltz) to grease the wagon wheels. Also great for frying and topical application as a liniment for aches and pains caused by strenuous farm work. There was her famous "heart-attack snack", salted chicken fat on a thick slab of homemade bread! Yummy!

It is officially April 2nd- and this ain't a joke! We never malingered about an illness to avoid school when Grandma was aroud- her remedes were far worse than school!

Might even call for the "Break Free".

Depends on the particular form of photon; is it wave or particle or both at the same time? The mass or energy can be important as well.

You guys have me concerned. I thought I didn't have to service the ISO bearings until the indicator light came on and I can't even find the darn light!

The manual doesn’t say, but I always use the Delicate cycle myself.

That reminds me, I need to change my hubcap gaskets.

Someone accused me of losing my bearings years ago! Or was it a 'screw loose'???

I've always read that ISO has a bearing on noise, so it made me wonder even where these bearings are located? I've always assumed it was similar to dual pixel technology, where it is embedded in the sensor array. I know it has to do with the deep well capacity of the photosites, so the bearings must be at the bottom of the well? Do full frame cameras need the bearings changed less often because they have greater well capacity?

Easier to buy a new camera, you could damage the camera opening it up to clean or replace, everything else is done too on the new one.
