The HL1 link lowers
the rear approx. 1" and the HL2 link lowers the rear approx. 1.5" on most
fit 08-up models except the SM/TE610/630. Also will not fit
610's. These two links replace stock link assembly PN: 8000 A 4428.
HL2 Link Shown Above
Lowers Rear 1.5" On Most Models.
The HL2 link will not work on at least the 07 TE450, 05-07 TE510,
& 06-up TE610/SM610 unless the swingarm tunnel and/or the bottom of
the spring is ground approx, 1/4" for clearance. The HL1 link may
also require some filing for clearance as it is only 3 mm's shorter than
the HL2 link. The HL1 link lowers the rear only 1".
Thanks to Stefan Appelgren
over at R&D Husqvarna/Australia,
we have a link to a detailed installation of the HL2 link on the 2006-up
Husqvarna TE610: http://www.offroadexplorer.com/ORE_Garage/Technical/KoubaLink.html
The first picture below
shows the spring to swingarm clearance with the stock links on some of
the Husky models, if your bike has only the clearance shown below with
the swingarm fully extended then the spring and/or swingarm tunnel will
have to be filed. When using the HL1 link, approx 1/8 inch more clearance
is required. When using the HL2 link, 1/4 inch more clearance is
required. *Sometimes the shock spring and spring retainer can
be rotated a few degress to get maximum clearance. If your bike has
1/2 inch plus more clearance than shown below then filing the swingarm
or spring should not be required.
Thanks Mark Compton
for the picture above of his 05 TE510 with stock links.
The picture below is an
06 TE250 with the HL2 link installed showing the shock clevis hitting the
rocker and not allowing the bottom shock mount eyes to align when the swingarm
is fully extended. A reply from a customer is below this picture
with a description of what has to be done to gain the clearance requirements.
I finally installed the HL-2
lowering link, and as you mentioned, there was a need to machine the tunnel.
Easily accomplished with a dremel and coarse sanding barrels. Also, there
was a need to machine the rocker at the lower shock clevis impact point.
I have not had a chance to ride the bike yet but I remain confident that
I can maintain the right geometry with the front end. Fortunately,
this era of Huskys responds well to the front end being pushed out slightly
to increase stability. I will keep you posted on my impressions.
1. Raise the motorcycle
with the center stand or milk crate, etc., so the rear wheel is slightly
off the ground. Remove the kickstand mount, lower chain roller, and
the 12 or 14 mm headed bolt (head size depends on year model) from the
lower shock mount. Then remove the 17 mm nut and washer from the right
side of the front link mounting bolt and also the 17 mm nut and washer
from the left side of the rear link mounting bolt. Push the bolt
out the right side. You may have to lift up on the rear wheel slightly
to allow the bolt to slide out freely.
2. Next remove both
link mounting bolts, pushing the front one out the left side and the rear
one out the right side. (*You will have to drop the rocker down slightly
to allow the rear link mounting bolt head to clear the bottom of the swing
arm.) After removing both link mounting bolts the stock link should drop
out the bottom and you are ready to install the longer KoubaLink.
Before installing the new link be sure and grease all of the bearings including
the ones in the KoubaLink.
3. Now that the
stock link is removed, install the KoubaLink in the reverse order, bearing
end to the front with the grease fitting pointing down. Move the
rear of the link up until the mounting holes line up with the hole in the
rocker. Push the rear link mounting bolt in from the right side and
install the washer and 17mm nut. Push the rocker back up inside the
swing arm and push the rocker mounting bolt in from the right side and
install the 17mm nut. Rotate the front of the link up and push the front
mounting bolt in from the left side. Install the washer and 17mm
nut. (You will have to raise the rear wheel until the front mounting holes
line up.) Torque all three 17mm nuts to approx. 35 ft lbs. You may
want to check the sag and if the full 1 1/2 inches of rear lowering is
desired, sag should be set at 100 mm/3.90 inches.
4. We recommend
sliding the front fork tubes up (approx. ½ inch) until they almost
touch the bottom of the handlebars. If quicker steering is required
we would recommend lessening the rear sag, which will subtract from the
1 or 1 1/2 inches of rear lowering. These links are as long as possible
for the maximum rear lowering, on some models the bottom of the shock spring
may rub the swing arm tunnel when fully extended. Grinding the tunnel
or spring slightly would produce the required clearance.
