New here. CVT issues with an 05.

Sounds excellent Ken.

Ken,
Congrats on a tough job well done.
How did you end up torquing the secondary shaft nut?

I wish you had not asked that question as I am sure I will be chastised for the way I did it. But you did ask so I will answer. Per the book, I used blue thread locker and I went into the back of one of my tool cabinets and dug out an old air impact that on a good day will deliver 175 lbs torque at 120 PSI. I set the air regulator at 115 PSI to slightly decrease the torque the impact could give. I held the adapter with a strap wrench and let the impact do the rest. I really don't know the exact torque I put on the nut although I am probably close enough for govt work. Let the flames begin but I'd bet I am very close to spec. I did use a torque wrench to torque the new bolt at 65-70 lbs. That bolt also got a dose of blue thread locker.

Ken, its to GERMAN spec's, Gutentight.

excellent job Ken, nicely done and thanks for the follow-ups and pics...

[MJR]

I think it's more likely a dealer mechanic would just use an impact rather than a torque wrench anyway.

Help!!!?/

I dont know what bolt Ken is talking about. There are none on the secondary and my manual and Le Dude say the primary shaft bolt is torqued to 46.5 lb-ft. What is torqued to 70 lb-ft? I am about to torque my primary shaft bolt (on the port side of Suzie) and now I am worried. My manual had the bolt in the wrong place, does it have the torque spec wrong too?

46.5 ft-lb is correct for your 07 650. The higher value is for the 03 and 04 models.

dangit got that backwards . 46.5 is for the 03 and 04 models. My manual says 67.5 for the 05 and later models.

Yup 46.5 lb-ft for '03-'04 and 67.5 lb-ft for '05-'12.

Craig, you scared me for a minute that I may have torqued the wrong value on the 06. I did get it torqued correctly at 65-70 lbs. As a follow-up, my friends bike is doing great and has 700+ miles on it and no issues. We haven't done very much riding for the past few weeks as heavy rains doesn't seem to want to stop.

Realized it as soon as I posted but it took me a minute to double check the manual and post the correction.

Ken you guys have been getting a bit of rain for the last few days .

I just discovered a posting that the guidance from Suzuki is to replace the primary pulley shaft bolt each time you take it out. After researching "single-use fasteners" on the web it seems to me this bolt does not qualify. Generally you throw away a bolt after one use if it has a special coating (corrosion prevention or threadlock) or it is a TTY (torque to yield) which generally means the instructions are torque it to spec and then add some degrees of turn. One example given was almost humorous:


Here is an example of what occurs when replacing the cylinder head bolts on one vehicle maker’s engine. The steps must be done in a specific sequence and if the sequence is not followed, the bolt can break, causing damage and difficult removal.

The six steps are as follows:
1. Tighten to 40 N•m (30 ft-lb). 2. Tighten an additional 90°. 3. Loosen 360°. 4. Tighten to 40 N•m (30 ft-lb). 5. Tighten an additional 90°.
6. Tighten an additional 90°.
These fasteners become misshapen and cannot be reused because of the excess amount of stress that was forced on them during installation

There are definitely two torque values for this bolt, page 14-45 in the supplemental section for the 05 model has the new torque value for the 05+ models

03/04 models ----> Primary Pulley Shaft Bolt: 64 N-m (6.4 kgf, 46.5 lb-ft)

05+ models -------> Primary Pulley Shaft Bolt: 93 N-m (9.3 kgf, 67.5 lb-ft) ) 05+ models
