HST Oil Change: Fact or Fiction?

[kromc5]

Not sure of the merit or not but I have always kept the intervals for most. I do the engine oil every 100 hours though. My 4320 never gave me any troubles or leaked anywhere. I keep all the intervals on my car as well with 120,000 miles only had to replace one sensor. I even go around and look at my relatives fluids. Hate to see transmission fluid that is burnt. My real pet peeve to see that most ignore the brake fluid and let it rust away the system.

From the records, you will not see engine or transmission related failures due to lubrication failure or progressive contamination. The build quality and lubricants are just too good.

What you will see is failure due to fluid VOLUME and gross contamination issues. Leakage both "out of" and "in to" what should be closed systems.

Frequently, expensive failures come down to a $3 rubber part. A seal lets go and all h**** breaks loose.

I bought a wood splitter years ago that has a pressure gauge on the filter side. Asking what it was for, the dealer advise that it was to reduce the occurrence of "recreational fluid changes" ! Owners feel they MUST change fluids every year, (to treat it right) even if there is no evidence to support the practice. None what so ever.

Automotive transmissions do not have anywhere near the level of filtration a HST has.

But, the fact is, you can NEVER get all of that stuff out, no matter what you do.

I don't see all the threads on TBN about oil related engine failures, and oil related HST failures, to support the hysteria.

Most automatic transmissions are also not working in the dirt and sharing their fluid with other equipment.

No you can't get it all out but you can get a lot of it out. I always do the first break in service, after that I might stretch the service some based on my usage but I always continue to change it.

Oil related failures are hard to track. So your HST pump went out at 1K hours instead of 4K, are you going to blame the pump or the oil for the shorter life? Most people on here are pretty handy and into maintaining their equipment. I would imagine people not changing their fluids is a small percentage.

You are right though, people are going to do what they are going to do. If someone wants to not change their fluids, it is their money and their equipment and they can do what they see fit.

Yes, if you want to change it, by all means have at it.

There have been some threads relating to factory defects. But, I'm not seeing all kinds of threads about HST failures, pumps wearing out, engine failures, engines wearing out, at any number of hours. It's just not happening.

It's time to ratchet down the level of anxiety, that oil concerns have provoked among TBN'ers. Especially for the nubies.

It's all good.
