Rotator gearbox?

Postby eazy89 » Tue Jan 03, 2017 10:21 am

I'm new to the auto power game. I have a 2.68 rotator gear box that's loud as ****. Sounds like I'm in a bowling alley. I like the power gear ratio on my 572hp 383. Thinking of switching to an ox box but it appears to be wider so I'd have to change my rigging. Any thoughts on what I can do or quiet this box down?

Some people have had good luck with changing up oils. I believe they've used Redline Heavy-Duty Shockproof. Might check with the manufacturer though on what oil they recommend to avoid any warranty issues by using non-recommended oils

Few questions

How old or how many running hours are on it ?

What lube do you run in it and how often do you change it?

Does it make noise at load, unload or just at idle?

From what i hear, the ox box will bolt up to your same rigging.

They bolt to both of the common GD patterns but I suspect he has concern with the housings dimensions not pattern. It will be close I bet.

The box only has 260 hours on it. and it only sounds like crap at idle. like a hollow rolling/rumbling sound.

Fairly common to growl at idle

You say ROTATOR oil well that is no longer a given.

Have you been running the thick 250wt Green oil or the thinner Red gear lube?

My gearbox does the same hollow sounds at idle I always thought it was the rougher cam making it do this but touch the gas and the noise is gone mine has very few hours maybe 100 on it and the oil is changed sooner then most I am sure. I was told it is just the gearbox nature? Mine is a stinger box I am told the new ox box does not make any noises even at idle.

Ox has helical cut gears as do some of the Torque drives, with Torque it was an option.

Rotator uses straight cut gears so they mesh differently and that creates the growl but they are strong.

The green was a 250wt gear lube and is no longer available last time we called their shop. They are now using a thinner multi viscosity red lube.

Worst drive I ever heard on a boat was a Precision it actually scared me that it going to frag, but that said it's still running!

I picked Rotator based on price and strength. Ox would have been my choice but it was like $1500 more than the Rotator when it was on sale last year. I have about 60-80 hours on mine and change lube every 20-30 hours. The manual calls for service every 30-50 hours but lube is cheap and with only 24 fluid ounces in the drive I think it should get changed earlier in Florida due to heat and humidity.

Lube: Use at your own risk, read the threads and pick what fits you best and remember Rotator advises fluid capacity of 24 ounces.

I am out of warranty and use the Redline HD with Lucas and it works great. My drive stays cool and it's noise output is what is typical for this type of drive. I had a Rotator (older drive) that ran Green 250wt and we swapped it over to Red and the drive acted exactly the same. We really saw no change to speak of but being an older drive it's noise level is slightly higher than the newer unit.

Rotator Red - order from Classic / Panther it sure looks and smells a lot like Redline last I checked it was 18$ qt but expensive hazmat shipping fees and tax.

Redline Heavy Shock Proof - blended with Lucas Oil stabilizer @ 20-30% - my choice out of warranty (Summit and Jegs offer)
If you order $100 in merchandise you get FREE shipping.

Amsoil - Dyna had used this with good results (Severe Duty 190wt or 250wt) Amsoil on line or local dealers

Lucas Gear oil- easiest to find 75-140wt or 85-140wt (no personal experience) but I see no reason it would not be good.

Our local speed shops stock redline shock proof and I thought it worked great! Box did eventually break however narrow gear and BBC stroker and a prop strike Or two might have had more to do with it. Don't know all the details! https://m.youtube.com/watch?v=M8dQZyr74qM
