New GC1720 Loud Drive

[fxdb96]

Hey guys on my new 1720 the drive seems to be really really loud especially in low. It is a loud whining noise. It goes away almost completely in high. I think it only makes the noise when the tractor is moving really. In other words if I would put the loader up against a stationary object and try to drive I don't think it would make the noise but I will have to try it. My gc1710 I had previously did not have this noise at all. It almost seems like a gear noise to me not really hydro pump whine. Has anyone else experienced this or have any ideas. I'm wondering if there is some bevel gear that's just loud because it's new and maybe after 50 hours it will quiet down.

Like the BH drift issue, my 2310 also makes a whiny noise, only in low range. Of course, when I'm using low I'm also in 4wd generally. Figured it was another "normal" noise. Tractor now has over 760 hours on it and nothing has broken, so....

Hope low range whine is normal... Mine has it also...

Well if owners are allowed to whine a bit why can't their hard working tractors whine a bit also<smile>.........

I may wine more than a bit but won't put alcohol in my tractor!!!!!

My GC1720 doesn’t whine, or maybe it’s my ears that don’t pick up high pitched noise. I’ve read about HS drives quieting down when switched to synthetic tractor hydraulic fluid. Probably a good idea regardless of whine, these transmissions get pretty heavily loaded and the expensive fluid is worth the cost.

Hydrostatic drives whine.

I'm not against using synthetic transmission oil. But, you should not hear a noticeable difference in whine, going from a premium fluid like he has, to a synthetic fluid. Or, notice any other substantial performance difference, in a premium brand hydraulic transmission oil, vs. synthetic, under normal temperatures. It's all good stuff.

Some have made all sorts of claims when they switched to synthetic oil. If someone wants to believe there is a difference, they certainly can believe they found one.

Amsoil makes a lot of claims for their synthetic oil. They do not make the claim their oil can, or will, reduce whine.

I was looking for it to quiet mine when I switched. I noticed no conclusive differences.

There is a big difference; The 100% syn no blend forms no sludge because it can survive extreme high temps without turning to sludge like conventional oil. It also flows at freezing temps that turn conventional fluids to rock. Get a couple of old frying pans and you will be amazed at the difference. At the ranch my neighbor also a rancher has issues in the winter starting but i dont unless the temp drops below 20 F. Since i began useing full syn i have never had a major repair and when i go to sell a vehicle i always have a waiting list. I always buy new and do meticulous maintenance. Are you familiar with the international diesel 6. ah oh? Well i have one pushing 200k running like new. most my friends owned bit the dust at 80 to 160k. It is factory stock. New D fuel has poor lubricity so i use a fuel additive and that may contribute to its health. The guy i sold my 94 bronco to wanted to give it back to me three years ago cause he didnt need it anymre for his boat. i aked why he didnt sell it and his answer was it had to many miles. i asked how many and he said almost 400k. i asked him what he had replaced and he replied just normal things the engine tranny transfer case and front diff were all original with zero repairs. I've been doing 100% since about 1978 i am 71
if you wish to keep a vehile forever syn is the only way to go. If you use a blend the conventional oils will break down forming sludge eventually killing it.

yep, cheap insurance as long as you use 100% syn no blends. They have saved me a bundle over the years

Did you ever read my post?

I specifically said: "I'm not against using synthetic transmission oil".

That being said, I have also had vehicles go over 200K. I scrapped a 1997 Villager last year with 248K on it, and it ran like new. It also never saw a drop of synthetic oil.

If you actually study the performance data of conventional vs. synthetic, you will see there is no substantial difference in lubricity, under NORMAL TEMPERATURES.

This is because the evolution of synthetic oil, has also led to the evolution of conventional oil. Making both equally as good, under NORMAL TEMPERATURES.

Which is why I said, "or, notice any other substantial performance difference, in a premium brand hydraulic transmission oil, vs. synthetic, under NORMAL TEMPERATURES".

Synthetic oil only has a performance advantage in extreme temps. And, if you want long drain intervals. It cannot solve world hunger, and peace.
