Alignment tool

Hi,

since last summer Ive been facing the belt chirp issue, mainly on every first kilometers.
So I want to purchase the tool for tension measurement and the alignment tool for the rear wheel.
They sell it here on the German ebay for a reasonable prize (not OE), but Im wondering why they say its only for models as of 2014...?
https://rover.ebay.com/rover/0/0/0?m...2F401743586445
Is that correct, were the any changes in 2014 or is the alignment tool also to be used for my 2012 Bird (model year 2013)?

BR
Michael

Save yourself a lot of time and money and just get a laser alignment tool that clamps onto the pulley. This is the one I use: https://thomasperformanceparts.com/inc/sdetail/194/201

Basically, you set the belt tension first; again, no special tools required. Just measure the deflection in the lower belt guard window, 0.5 to 0.75 inches of deflection. Most who do their own service generally agree that the Service Manual specification for belt tension is too tight. With deflection set, lock down right hand side then clamp on the laser to the pulley and sight along the edge of the belt, adjusting the left side until the laser tracks the edge of the belt in a perfectly straight line. Lock down the left hand side and you're done.

Search the forums and you'll find more details.

I had to find the belt guard window behind the exhaust first ... but I didn't get it yet. You mean to measure the deflection just by loose hanging or what? Actually, acc. to the small manual with the bike, the belt is to deflected by the defined side load with the tool (10 lbs)? I'm puzzled...

The laser tool is a good hint, thank you!
However I'd like to jump a bit further and try to get a tool for other tasks as well? My son owns a YZF-R125 with chain drive... a magnetic fixture could help there as well as it holds to the sprocket as well? I'm just not sure how to fix that one to the T-Bird's pulley...

Maybe purchase a simple laser tool and machine my one universal fixture? Actually this shouldn't be a big deal, the only thing you have to do properly is the exact alignment of the laser beam with a defined plain on the fixture...?
Any recommendations on that..?

You could use a belt deflection gauge to push on the belt with exactly 10 lbs of force. Or, you could just push up on the belt with your finger until it stops (before your finger hurts) and measure the difference with a ruler. That's what I do; it's not super critical.

Take a look at the tool in the link I attached to the post. The laser clamps to the belt pulley and is adjustable. There are others that are magnetic.

Really should not be necessary.


Outside of belt adjustments following tire changes, I've only ever had to make a mid-season adjustment once in 6 years using the above method.
