What oil is best? and what ratio?

[bwalker]

No idea. Check all the exploded diagrams from the online parts stores like babbits or country cat.

I will say this: the oddball 16" x 156" x 1" 2.52 driver track is no longer made. It was used on the bearcat 440 ll, the many later bearcat 570's. So if it's one of those, u gotta snatch up used tracks the second they hit the used market. I got one coming to Alaska all the way from Montana! $125 usps ground. Ouch. Obsolete odd ball things are a btch.

Could one put a different set of drivers on it so one could use a common size track?

Yep, I do firewood, slabs and logs with ole sht box bearcats.

Or really any older 2 stroke utility sleds. So ive used the lucas oil stuff all my chainsaws, yamaha, polaris, ski doo and arctic cat utility sleds, evinrude and yamaha boat motors and solo ice augers.

The lucas stuff pours from a jug at 30-40 below zero. When I go into town for supplies, I despise bouncing all over trying to find some sort of special oil. So the lucas stuff is convenient.

Lottsa amsoil zombies up here. I dunno how people can afford that sht.

The reason I like the bearcats over the polaris widetrak lx:

Wildwood hydraulic brakes vs cable brakes.
Stronger motors with more torque with aggressive ports and flat exauhst ports. 488 fuji has a round, lazy exhaust. Giant koyo barrel roller bearings on pto side. As opposed to spindly ball bearings in the polaris fuji.

On the bearcat 440 ll, longer stroke than the skandic 440. 65 mm vs 61 mm. Better wide ratio clutching as well.

Dumbest fkn utility motor ever: 600 etec.
I call em al gore 2 strokes, just look up iso flex grease crank bearings.

I've hated working on ski doos since I was 16 years old. I like our mercan sht. Long live polaris and arctic cat!

If I wasn't constantly spending money on my timbersale, the polaris titan would be my choice.

The 600 etec is a stupid choice for a work sled. The ACE four stroke woukd be OK, if it were not for the fact it weighs a ton.

Useful pictures. The truth is what shows.
Thanks

One other thought in regards to Red Armor and it's weird ability to provide for lots of residual oil. I think it might be an illusion. I've been dying Maxima K2 red using off road diesel fuel dye. When doing this it looks like it has a ton of residual even at 40 or 50:1.
I cant say definitively that the red dye makes it look like there is lots of residual oil, but this sure looks like it to me.

The clutch eats uo roller bearings. Isoflex bearings were a good idea with poor execution.

Why? End or side load?

Could one put a different set of drivers on it so one could use a common size track?

Yep if there's a will there's a way. It depends on which model sled. Going from 2.52 pitch drivers to 2.86 drivers, gotta pay a shop to use a hydraulic press and different length pipes to press on new ones. Thats if the track driver shaft isn't some odd ball size.
Then the bill turns triple the cost of a direct swap/used track.

Other instances, u can go to 15"x156 tracks and trim the lugs until you've got tunnel clearance on an older sled.

Sometimes the rear suspension skid can be modified to a shorter or longer track.

Ski doo did this odd ball track thing as well:
139" track on the tundra r and an even more odd ball 1.97" pitch.

Polaris had the occasional odd ball: 20" x 141" on the widetrak gt.

When the clutch moves in and out with changes in rpm it sideloads the bearings. This constant axial load just kills roller bearings.
