Chain case oil removal???? - Snowmobile Forum: Your #1 Snowmobile Forum

RMK4Fun · 01-21-2013, 08:55 PM

Howdy,
Need some advice on what tool would be best to remove chain case oil from my '90 Polaris 500? I have read a few articles about just draining the oil into the lower body of the snowmobile, but I wonder if there a siphon small enough to go into the fill hole and pull the oil out? Or is the old to thick and I should just pull the cover off?

Any advice would be greatly appreciated.
Thanks
Bob

I put a small bucket under the exaust hole and pull the cover and let it run to the hole. If you wanna make less mess you could always do something fsncy like lay tin foil down and cut out a hole for the exaust hole. Dont try to siphon it, wont get it all out anyway. Also check the tension on the chain. Loosen the lock nut and it should be as tight as you can get it by HAND and then out 1/4 turn.

Turkey baster with about a 8 inch long clear water line over the end from any hardware store will do the the job. It will fit right in the plug hole. Cheap, and works great!

Don't let your wife catch you using it, though

what kind of oil is supposed to be used in these chain cases'? 80-90? that might be a bit heavy... i ordered a manual for my XLT but hasnt arrived yet. proly would be a good idea to open mine up have a look at what gearing i have and change the oil, since there are a few threads with people asking Q's about chaincases on these mid 90's polaris sleds

Chaincase oil is specified. The synthetic stuff is a bit spendy, but a quart does 3 sleds. Some guys use motor oil, some use ATF. Some guys also use gear oil, but a lighter oil penetrates into the chain much better. Heavier oils also cause greater drag and some loss of power, especially when the oil is cold.

On my machines that don't have a drain plug, I tip them up on their left side, remove chain case cover and use a suction gun followed up by a shop rag. I use the Polaris chain case lube (non-synthetic) on my older machines (bought a gallon 20 years ago and it's now just about gone).

I bought 12oz amsoil full synthetic for 6.50ish. My sled only took like 4oz, but i understand most take around 8?

Most polaris sleds take about 8-9 oz, 11 with reverse chaincase

I used a suction pump. Sucked out 96% of it. No mess at all

RMK4Fun · 01-25-2013, 12:05 PM

What kind of suction pump do you use? I have a pump for removing motor oil from lawn machines, but the hose is to thick to feed down the little hole! I am going to try the turkey baster, but it's hard to believe gear oil will come out the little tube! I do like the foil trick and the exhaust hole.....

Just thought it would be easy to suck it out, then remove the cover. Just need the right tool!
Thanks for all the input.

Or do like steepndeep suggested. Remove the exhaust, put the sled on it's side (on a piece of cardboard or carpet), remove the chaincase cover. Use the turkey baster or suction gun. No mess, and allows you to examine the inside of the chaincase for potential problems, too!

Thanks for all the input.

you can get these suction pumps anywhere.
come with diferent size tubes for different jobs

RMK4Fun · 01-27-2013, 12:20 AM

Cool,
Got the pump, and took off the cover. Then went and did my Polaris Indy 400 too. Adjusted the chain tensioner, and checked the gear sprocket bolts. Cleaned it up the best that I could, and inspected the chain.

Got it all back together, but now I am not sure about how much oil to put in. In my searches, I see it's either 8 oz. or 12oz. The cover has a rubber plug in the middle, and the a bolt with rubber sleeve down lower. Is that the fill level? Or do you fill it up until it comes out the hole where the rubber plug is. Will the 1989 Indy 400 take a different amount than the 1990 Indy 500?

Any advice is greatly appreciated, and I will double check my manual, but I did not notice the lower rubber hole with the smaller bolt in it.
The other quick question, I assume it's ok to use Polaris synthetic chain oil in these older sleds?

Thanks
Bob

steepndeep · 01-27-2013, 11:27 AM

The small bolt with the rubber sleeve down low is the fill level. Fill through the large rubber plug until it comes out the lower hole.

Josh Kidner · 01-27-2013, 08:27 PM

You could use any chaincase oil made for sleds. I have amsoil full synthetic, only because its the only kind i could find without having to order it online.

RMK4Fun · 01-27-2013, 09:13 PM

Cool,
Thanks for your help.
Both sleds went for a 65mile spin in 5"of fresh!

Ran well, but I still need to replace the fuel line going into the tank.
Guess that's my next search!
If anyone has a link on changing fuel lines in the tank on 1989/1990 Polaris Indy sled, feel free to send it over!

They are going out next weekend again!
Pray for more snow.....

Thanks again for all the advice,,,,,

Josh Kidner · 01-27-2013, 09:18 PM

There should be a metal fitting where the line goes into the tank. Take it off and the line in the tank (if it hasnt completly fallen off) will be connected to it. Replace the line and put it back

RMK4Fun · 01-28-2013, 12:05 AM

Josh,
Thanks so much for the response.

How do I get to the fitting? Do I need to remove the air box or Oil tank?

Thanks so much, looking forward to getting this done. I assume I can use the strainer at the end of the fuel line, with a bit of cleaning?

Enjoy,
Bob

**BC_Dan** · 01-28-2013, 12:14 AM

On my 90, I was able to remove the fitting without removing anything. The hose is clamped on with a clamp that isn't reusable. I tried spring clamps and screw clamps and could not find anything that was small enough to go back in the tank. I ended up getting some fuel hose from a chainsaw shop that grips TIGHT. I pushed it on and then really pulled to try to get it off; nope. It stayed.

The weighted filter on the end is usually not very dirty. If it is, a quick bath in carb cleaner or brake cleaner should get it back to serviceable .
