Concern about my new TC fluid

I just changed the fluid in my transfer case today, and I used the recommended factory Toyota transfer case oil. The oil came in two 1 liter cans, and I used a can opener to peel back the lid in order to pump the fluid out. After it was all said and done, while I was cleaning up, I noticed tiny particles (maybe metal shavings) in the left over oil in the cans. I have no idea of knowing whether they were very small aluminum shavings that occurred while opening the can, dirt, etc. Should I drain the oil again and start over? Is there any reason to think tiny aluminum shavings would harm the components inside the transfer case? This might be a dumb question, but If the fluid needs to be changed again, could I safely drive in 2wd until I can get it changed? Thanks in advance.

 

If you pumped out the oil, I’m thinking gravity helped you in this instance by keeping the shavings weighted down in the bottom where you see them. There is no way to tell for sure. If you doubt yourself you can drain and refill using the same fluid. Get yourself a paint filter to filter out any ‘potential shavings’ before re-use. Keep us posted.

 

Try to wipe up some of the particles with a paper towel. Then let it dry and inspect. Lots of times small bubbles can look like metal particles

 

Possibly if you used a metal church key or screw driver you’ve induced the metal you see in the can. I only allow our turbine oil to be opened with a composite opener. I’ve borescoped Aircraft engines that have damaged caused by oil can metal later verified by tear down shops. I’d say our trucks tolerances are not that of a GE and if you pumped from can your probably good.
