Grizzly 700 Clutch installation

We decided to go with 4 Kodiak weights and 4 660 Grizzly weights. The parts numbers are 5GH-17632-00-00 and 5KM-17632-00-00 respectively. Overall impression is nice low returned back to you if you have switched to over sized or heavier tires. We recommend you to refer to the service manual before trying this install.

(1) Remove (6) (4mm) Allen screws and (4) (10mm) bolts to disconnect and remove right side floorboard from the Grizzly.

(a) Remove the side panel for better access.

(2) Remove (12) (10mm) bolts all the way around your Drive belt cover and remove.

(3) Remove (4) (10mm) bolts from the metal Bearing housing and remove the bearing housing.
* The two longer bolts are located on the front and rear corners of the bearing housing. (Don’t lose the two dowel pins in this section of the take down).

(4) Take the two long bolts from the previous step and insert them in the two holes on the rear pulley / secondary sheave. Tighten and leave them in. This will loosen the CVT belt and allow the primary sheave assembly to slide of easily.

(5) Loosen and remove the 22mm primary sheave nut from the primary clutch shaft.
NOTEYou can use an impact driver for this but we recommend using Yamaha part number 90890-01701 YS-01880-A Sheave holder Primary clutch holder. It is your motor!
NOTE this nut is a standard right-hand thread so turn it Counterclockwise to remove it
NOTE the primary sheave nut has 100 foot pound of torque on it.

(6) Remove the primary pulley sheave assembly.

1.Remove eight small screws and washers from the primary sheave assembly. And remove the primary sheave assembly cap. Take special care at this point as there is an O-ring on the assembly.

2.If you are careful and keep the grease clean you should not need to regrease anything.

(7) Swap the weights out i.e. (Kodiak weight 660 weight) all the way around the assembly.
NOTE: a small amount of grease on each weight will help hold the weights in place.


1. Install the primary sheave back onto the main clutch shaft taking special care that the splines align on the primary clutch shaft completely. An extra set of hands are very handy at this point to hold the primary sheave in place.

2. Install the 22mm nut and washer and just snug down.

3 Install the primary sheave assembly cap and the 8 phillips head screws and tighten to 2.2 ft. lbs.

4. Hold the primary sheave in place and tighten the 22mm nut to 100 ft. lbs. (Again you can use an impact wrench but we do not recommend this.) NOTE: MAKE SURE THE SHAFT SPLINES ARE COMPLETELY ALIGNED WITH THE PRIMARY CLUTCH SHAFT.

5. Verify the 2 dowels pins are still in place and re-install the bearing housing and tighten the 4 bearing housing bolts to 7.2 ft. lbs.

6. Place bike in park and start the engine. Rev it up several times noting the phasing of the primary sheave and belt.

7. Once satisfied of the proper clutch operation re-install the drive belt cover and tighten the 12 drive belt cover bolts to 7.2 ft. lbs of torque.

8. Re-install the floor board and any additional plastic you may have removed.

Installation Complete!

Awesome step by step install. How much were the new kodiak and 660 weights? Basically, total project cost?
Total for the 8 weights was 32.00. I did have to go to the hardware store and purchase a deep well 22mm socket for 4.99 also.

How long did it take ya to do the whole install?
Overall time is hard to judge as we were taking pictures and notes. I would estimate 1.5 hours total.
My quad will still run 62 MPH. Didn't see much from the bottom end. Huge notice when you run along at 5 MPH and smack the throttle. She takes off like a rocket there.
Only use the Yamaha Ultramatic grease. I am not sure what 4 bolts you are referring to.
It isn't normal. Captjack is going through the same thing you are right now I believe. Hopefully he reads this and can chime in.
Quite possibly it is the one way bearing in the housing. My manual is missing at the moment so I cannot look it up for you.
Can you be more specific on the whining noise?
You can really do it either was mexhusky357. I felt it was easier to remove the sheave and cover in case I needed to clean the grease and add fresh grease. I have since done it both ways and still find it easier the to remove the sheave.
The other grease may work. You will need to check it after you run it though to make sure it sticks to the roller weights adequately though.
wow totally lost now.. thought lighter weight was supposed to give you more low end. crawlability but lose top end speed, now you are saying the heavier weights gave you better low end???
Don't worry, I am in the same line as you. I thought the same thing.
Wow, you have me as to what the problems is. I am not a clutch expert but hopefully someone has had a similar issue and will chime in.
