What will you replace the Chaincase lube with??

[yamadoo]

Sled dog,
I agree, they will likely all 'work'.
As to why some leaked dry and what to do about it is a mystery to me.

I use/used Torco Racings SCC Synthetic Chain Case Oil in every sled I've owned. It exceeds GL-4 ratings and is thinner than gear lube allowing better friction protection in cold weather use. When it's -25 outside you would have to let the sled run for hrs. before gear lube would start to warm up enough to flow like the SCC Chain Case Oil. The initial friction experienced while gear lube is getting warm enough to penetrate the chain is what will cause quicker chain failure.

Here's the data sheet for Torco SCC Oil http://www.torcoracingoils.com/images/product/SCC.pdf

Sled Dog,

I see your point, but to me it's apples and oranges. Engineers will find they are wrong with unproven, new designs as in the engine (rings), and handwarmers (hooked design).

When it comes to experise in oil applications for a gear box, I have to expect they'll know what they're talking about. Come on now, this isn't a living organism, it's a couple gears and a chain.

FYI ATF has similar viscosities to the SCC Chain Case Oil.

For those who insist on a 75W90 lube because the belt cover states to use this. I would use the Torco RTF (Racing Transmission fluid). It is rated for use in all applications where SAE 75W90, 80W90 or 90 is specified. Also replaces SAE motor oil 10W30, 30, 10W40 or 40 where specified for transmissions. It is GL-6 rated, vs. Mobil 1 is GL-5 rated.

Unproven like oil disapearing from a chaincase with no sign of leakage a hot chaincase and the smell of hot oil. Yes it is only gears, chain and a seals that is why any oil would work for awhile but if its disapearing by getting distilled from heat then a better oil is called for so use synthetic no matter what kind you end up using.

Redline superlight shockproof gear oil here. Thin stuff like ATF but has the lube properties of 75-90w gear oil. I have been using it for many years and 20k plus miles in various diff sleds and never had a problem.

I am not insisting on anything, I said I think they all would work. I personally believe we could not detect a difference in track hp or longevity with any of the choices.

Yamadoo, no worries man; I wasn't implying that you insisted on using a 75W-90. I figured I would place that in my post before somebody did though. I know in the previous topics about Chain Case Oils; there were guys who did because of the belt cover and many ran Mobil 1. I feel (I work in the Oil Refining industry) that the 75W90 gear lubes are too cold for that initial wear protection in a roller chain application. The Torco Race Transmission
Lube is a oil that is specifiacally listed as an alternative for this weight of lube but; with a lower initial viscosity. It's still not as thin at extreme cold like ATF and the Torco Chain Oil though.

Take it from a guy who works in the field; I would spend the money for the Torco Chain Oil and not wory about the chain prematurely failing or; go with ATF which has relatively similar properties followed by the Torco Race Trany Lube rather than run a thicker gear lube.

FYI I have 2867 miles (835 miles in boosted mode with a 162" x 2" track) of mountain riding which puts a heavier work load on the chain case than standard trail riding. I sill have over half my ajustment left in the chain tensioner with no slop evident in the rollers when I changed my cheap anti ratchet (sprockets w/ stock) drivers out due to the Super Charger induced track ratchet 50 miles after the install last season for some quality extrovert drivers last month.

can't you just use regular old transmission fluid?

Yes but for better oiling when it is cold and hot plus having a cooler running chaincase synthetic would be the better route. Buy one liter and it should last you two years. Pretty economical when looked at that way.

How often do you have to change the gear case lube. Is once a year good enough or does it go strictly by how many miles are on the lube?

oil

i have been runing atf for years. wiith no problems t jet,s , srx,s, gpx,s & rx 1. it hase never left me any were on the ice oval.s or on the trail.

Once a year is plenty especially if what your putting in is synthetic.

I use Amsoil synthetic 2000. I change it every year and never had a problem. (knock on wood)
