ZF350A Transmission

Why not just use the ZF filter??? It's $16,000 to rebuild one of those gears, start to finish. Just the oil pump alone in that gear is close to $4,000 installed. Is it really worth $40 s in savings, honestly???

It's just a very overpriced white filter with a ZF logo and the part number.......no other markings.

That's true, but put a filter that doesn't do it's job, or one that explodes or leaks and you will have a very overpriced rebuild at $16,000. I think I'd rather pay for the overpriced filter and have piece of mind. Look up Kafue's thread on his gear rebuild and look at how much hassle, money, time lost, and 2 rebuilds later, over having the wrong filter in his gear, which was installed by the rebuilder by accident........

That was the wrong type of filter not the wrong brand, there is quite a difference.

True, but if a fram is as good as the automotive ones, you might as well have the wrong type of filter in there. The fram cases are very weak and crush easy, the bypass valve gets stuck on them, it is definately an economy filter I wouldn't want installed on anything of mine.

What were sodium and iron levels?

I am curious as to why the viscosity dropped by nearly half after 400 hrs.

Old post but just read the thread and couldn't help but to comment.

What color does unburnt fuel add to a diesel engine's lube oil?

What color is a diesel engine's lube oil after running long enough to acquire a measurable percentage of fuel dilution?

What color is diesel engine lube oil after running for 2 or 3 hours?

What makes diesel engine lube oil that color?

I am also curious how the viscosity dropped so much ... was a sample of the new, unused, oil submitted at the same time for comparison? VI shear? Wrong type oil?

carbon was on his mind but got lost in translation

Could be. Source seems to have a very high miss rate ...
