Washers under head bolts????

[motonoggin]

If I remember right, Polaris recommended that anytime you had the cyl bolts out to install the washers.

I'm sure you've seen this in the tips.... but just in case.

Team Tip S-05-09-02 Reminder: 2005 900 Cleanfire Engine Cylinder Bolt Washer Addition
The possibility exists where the bores drilled for the cylinder bolts in the upper crankcase may not have been
drilled deep enough or metal shavings may be at the bottom of the bore(s). When this occurs, the cylinder bolt
clamp force is reduced even while the desired cylinder bolt torque has been reached.
The primary symptom is a white-carbon build-up on one spark plug metal casing wall.
If this symptom occurs, Polaris recommends the following action:
1. Drain the engine coolant.
2. Remove the cylinder head. Discard the o-rings.
3. Loosen and remove the cylinder bolts. Install a washer, PN 7556234, on each bolt. Re-install the cylinder
bolts and torque to 34 lb.ft. (46 Nm) following the torque sequence in the service manual.
4. Re-install the cylinder using new o-rings and fasteners. Follow the recommended torque specifications and
torque sequences in the service manual.
5. Re-fill the cooling system. Bleed the air out of the system and test.
Polaris recommends the washers, PN 7556234, be added to the cylinder bolts WHENEVER the engine is
removed or re-built for any reason.

So, I'm still confused. Was this also an issue for 2006 or not? The team tip jsledder posted says this is for 2005 900.

I would follow this guideline.

can i get these from a hardware store? 10mm by 2?? is what my dealer told me..but what are these measurements...the thickness and the diameter?

ahh i see sorry my mistake, then what is the benefit to this if you arent having any problems...

Even if you're not having problems the addition of the washers will help in better torqueing of the cylinder bolts as the the bolt tends to stick when being tightened against the aluminum. The steel washer will give it a slicker surface to tighten down on.

Thanks for the clarification guys!

 

[paramuir]
