Im about to put my new short block back into my 09 Assault and I have a few questions.

1. What is the torque and torque pattern for the cylinder head bolts?

2. How would I go about bleeding the oil pump with the engine installed in the chassis? Looks like there is no room to get at anything when the engine is installed.

3. Whats the torque for the motor mounts?

4. Primary bolt torque?

5. Will I need to prime the fuel system and if so, how?

Thanks in advance for any input.

Im about to put my new short block back into my 09 Assault and I have a few questions.

1. What is the torque and torque pattern for the cylinder head bolts?
25 ft lbs & see diag below.


2. How would I go about bleeding the oil pump with the engine installed in the chassis? Looks like there is no room to get at anything when the engine is installed.
With the throttle body off... you have fair access to the oil pump bleed screw...OR ... You can pre bleed it if you want, on the bench... as long as there is oil in the line with no bubbles as you install... when hooking up to the oil filter (which is where I assume you disconnected the line)... after install of the motor... put a "bib" under the lines where you are joining them and allow oil to flow from the filter and fill the line... push them together and reclamp after any bubble is gone at the junction.

I'd still like to see you crack the bleed screw open at the pump after all this is done.

YOU SHOULD RUN PREMIX IN THE FIRST TANK OF GAS AS WELL.
From the Polaris Manual... [the older manual went into more detail]

BLEEDING DURING ENGINE ASSEMBLY
During the engine rebuilding procedure, the oil in the oil lines may be depleted of oil fluid. It is important to have these lines full
of oil at the time of assembly. For this process you will need to have oil in a small squeeze bottle to fill the oil lines. It is also
important to have no air bubbles in the lines.
1. Attach the oil lines to the crankcase, and apply the line clips to the fittings.
2. Fill each line with 2--stroke engine oil.
3. After the engine is assembled and in the bulk head you will need to bleed the main line.
4. Fill the oil bottle so the oil level is over the hose insertion level.
5. At themain line, clamp and disconnect the line that goes into the in--line filter. Oil should be present in the line from this filter
to the engine.
6. Air that is in the line that you disconnected can be purged by raising the line higher than the filter and releasing the clamp so
that the air can escape.
7. Repeat this until all air is gone from the line.
8. Place line onto the filter and apply the hose clamp to the barb of the filter and the oil line.
If air is in the oil line at the in--line filter and the engine has not been removed, start at step 5.

3. Whats the torque for the motor mounts?
See pic below

4. Primary bolt torque?
80 ft lbs... re-torque after first 2 minutes of running on the snow... then again after the first day. IMPORTANT!!

5. Will I need to prime the fuel system and if so, how?
There is a complete thread on this with photos...do a search for the keyword "prime" in the advance search feature.

Thanks in advance for any input.

Thanks for the info MH.
