Sinar Norma Front Standard Seized Up

**MCohn** · 17-Sep-2023, 05:57

Hey all,

Need a bit of help. So yesterday the knob that controls front tilt totally seized up. How does one actually take the knob off to clean it and lubricate that point? Everything else is working just fine. Thanks!

Hey MCohn,

See the original instruction book. That tilt knob needs to be unscrewed, cleaned, and lubed. See Figure 18 and also page 13.

I use paper towels, electronic contact cleaner, old toothbrushes, wooden toothpicks, etc to clean out sticky NORMA parts. Work outside and wear Nitrile Gloves!

Daniel, thanks for the SINAR download

Petro should not be used

The Fresnel and DDS statements seem odd

Mornin' TC,

"Petrol" I believe they are referring to "white gas" same thing as "Coleman Camping Fuel". Pick yer Poison. Philip Morgan recommended the Electronic Contact Cleaner, available at any hardware or auto parts place. Don't breathe it or get it on your skin! NITRILE GLOVES.

Norma Moly Grease by Nokton48, on Flickr

"Premium Moly EP Grease Grasa Tipo Moli EP". Suitable for Ford Lincoln Mercury chassis, drum brake bearings, u-joints, etc. Lithium 12 Hydroxy extreme pressure grease. FYI: On the left in the tiny tin, is Sinar Norma original grease, which came with one of my cameras. Sinar used to tape the tin of grease (in a Sinar logo imprinted manila envelope) to the inside cover of the instruction book. As you can clearly see, it's about the same thing. I use a flat wooden toothpick to apply just the tiniest amount to the Norma lube points. Then buff off any excess. Sinar says "just the lightest emulsion coating" which is not much at all. The action should be super silky smooth.

Lighter fluid is a safer solvent around nearby plastics, and less hazardous to you and parts...

Yep I use lighter fluid too, but frequently it doesn't cut it. If Contact Cleaner doesn't do the job, I move up to Acetone to remove really stubborn deposits.

After applying the liquid, tap the parts lightly with a brass hammer, wooden mallet, or something similar. The induced vibrations help the liquid to penetrate. And give it plenty of time to work. I had a Graphic View Camera with a seized rise and fall shaft. I sprayed with Liquid Wrench and tapped repeated!y for three days before I freed it. Note these camera parts were all metal so the spray was safe.

Philip Morgan recommended "Liquid Wrench" to remove REALLY jammed on Norma parts. I bought some but haven't needed any yet. Good to have around the shop.
