2008 Vector Stator Replacement

[steiner]

Replaced the stator in a buddy's 2008 Vector. Thot I would share how I did it without pulling the motor.
Removed the oil tank and steering linkage.
Tank and seat were next to remove the bolts for the exhaust including the flex pipes.

Battery and battery holder were removed
Removed secondary to get the long motor mount rear bolt out and the 2 front motor mount bolts were removed.

Coolant line running up to the stat was disconnected and clamped off.
Lightly suspended the motor with strap to the winch in the ceiling.
This made it easier to wiggle the motor back and forth a bit as some of the cover bolts are hiding behind the bulkhead.
Once all the the cover bolts were remove the cover will come off the flywheel if pulled straight back.
It takes a bit of finesse moving the motor around but there is enough room to pull the cover out.
The bolt circled here is where a little black clip gets attached to hold the wiring harness from the stator.

You can see the the burnt coils.
The shaft and the starter engagement gear will fall off as you pull the cover off. Not to worry as you can easily put them back in before you put the cover back on.

Nice write up! The more I learn/read about the differences in the amount of work/effort needed between the 3 cylinder and 4 cylinder motors (case in point, the starter location), it just amazes me.

As a side note. I just replaced my stator on my 06 Vector. Same routine. I ordered an after market stator, but the wire harness was shorter/different that the oem part. Didn't want to risk installing the aftermarket stator, so ordered a Yamaha stator I found on EBay. Was the same as the original. Also on mine, I had to remove the two guide pins for the stator cover to get it back on properly. It's definitely a big job, not for those who are mechanically challenged. Unfortunately, my stator still looked good, but I had to replace my seized starter motor anyhow, many of the same steps.

How many miles on the 2008? Mine has 14k miles on it and I noticed the peak rpm was dropping by 700 rpm at times with a noticeable loss in power. This was the first symptom of a bad stator on one of my older sleds. It also wants to stall out on a cold start which is unusual for this sled.

 

[steiner]

Not sure. Not my sled and the owner stated that it was rolled over and had to replace the cluster last season.

Why did you have to remove the flex pipes? I must be missing something.

 

[RobX-1]

If needing to wiggle the motor back and forth is needed, then removing the flex pipes would also be needed as they could possibly get in the way and/or prevent you from positioning the motor; especially if needing to tilt the motor forward/backward.

You have to move the motor back, forth, up and down to get all the cover bolts off and to remove the cover thru the opening. Was also an excellent time to install new exhaust donuts as they were toast.

Steiner is absolutely correct. It's a little tricky to get at all the stator cover bolts. The more wiggle room the better.

Even with the fuel injected 10 up it has to be done? seems like a commone problem with yamaha's. I'm keeping these 3 vectors we have until we can't ride anymore so I'm curious about this common problem. Although I never had one with the past machines that made it to near 10k before selling
off.

I’ve got 8 Vecs in our “family” fleet now ranging from 2010-2015, 10k-25k, I’ve never had a stator go bad…….knock on wood.

makes one wonder why ? type of use? battery quality? high amp draw led lights ?
