Is bleeding the oil and coolant the same on my 96xt as with how-to's that are all over the site here? I'm close to putting it back together if I can get the cylinders honed. I still have to do alot of cleaning on it but it's finally coming along. I should take some more photos.

But anyhow, do I have the two bleeder screws (one at t-stat and one at rear cross-over tube)? And if I pre-mix my oil and I check to see that I am using oil on that first tank am I ok with being assured the oil is bled?
 
Q1: Don't know if you have one at your t-stat but do believe there is one at the back. Look around. Easiest is to take a look at the crossover pipe. There is a bung welded to it pointing up that is your bleeder. You may need to remove the seat but as I said I don't know. See http://www.totallyamaha.com/snowmobiles/aaTECH/BleedingCoolant/ViperCoolantBleeding.htm for the viper technique. Most of it will be the same as your sled.

Q2: It is best to follow the lenghty oil pump bleeding proceedure. Bigger question is why do you think it needs bleeding?

See http://www.totallyamaha.com/snowmobiles/aaTECH/TechIndex/MISC_TECH.html selected sections of the service manuals is online the link is near the bottom of the page.

Finally not mentioned but what I advise and follow. Don't run premix unless you are not injecting. If you are running a 50:1 premix and also have the injector pump injecting at its normal rates you are effectivly leaning out your motor. The actual amount of gas could be as low as a 30:1 mix. Ya I add a little just for insurance but not a full mix.

As a side note most sleds run great with broken or non functioning oil pumps for about 7 miles. Quite a few sledders I know have had this issue. One even lost due to it catching on fire a "firecat" on it's first outing. Though I did a Vmax that ran without using oil for 3 weekends. The first resulted in a melted piston which was fixed then ran for 2 more weekends before it was noticed that it was not using much oil. I digress. What I am saying it the importance of a functioning pump cannot be overlooked.

Good luck.

Since he had his motor torn down I assume he disconnected his oil lines to the motor.

Correct you are.... The oil lines are still in the sled in my garage and the motor is in my basement....

And there is a bolt on top of my t-stat.
 
Then yes on the coolant proceedure. It really is not that hard. As long as you get the rear end up high enough.

And certainlly follow the bleed proceedure to the letter. Air in the line is a big problem.
 
Oh ya. Get a can of engine degreaser to help with cleanup. I use the "Orange" stuff to cut the grease/oil around the motor. Since yours is out I would suspect you have the bay spotless but if you don't it is a great time to clean it before you reinstall the motor and bleed the oil. The precleaning makes it easier to wipe up the bled oil residue. Also plan on using a bunch of shop towels. The only good thing it is is not gasoline.
 
I cleaned the bay. Spotless, that up to the one looking. It sure looks better than it did. I used some orange spray stuff to cut the grease this weekend in there.
