The 4 bolts you loosen on rear swingarm to allow for chain tension adjustment... A couple were really tight. I managed to get one out with impact gun. The bolt was really stripped.

So should I be able to tap out the old hole? And if so, anyone know the size/pitch of that hole? ( I don't think my tap will be long enough either).

Should I remove all 4 and put some never-seize on them?

What should they be torqued at?

 

On the bolt's 2 of the 4 are shorter. The 2 shoter one's that came out of the break side the manual say's 53ft-lb the longer ones which came out of the sprocket side manual say's 72.5ft-lb...

If I remmber right I think those bolts just screw into nuts that are welded on the bottom of the swingarm If you dont have a rear skid plate those nuts see alot of crap under there ya might want to put something on them....

If you tip the Z on it's rear grab bar you should beable to get @ those nuts..

 

thanks zbutcher. maybe I can just replace the nut end on the swingarm, if worse comes to worse.

 

NP, let us know how it turn's out. GL

 

the nuts are not welded on the swingarm.

they are on removeable plates. so if u stripped one u can just replace the plate.

 

do I have to get the plate from Suzuki ?

 

the 4 main bolts are torqued at 72.5 ft lbs. if you messed up the bottom plate suzuki will be the place to get a new one unless you have a used bike parts store around you. amd the bolts are 12mm I think not sure what pitch the threads are or how long

 

The 2 bolts on the sprocket side are 12mm break side are 10mm so say the manual & a plate hey opps my bad it's been a while that I have had to take that apart & it's a bit hard to see w/ a skid plate in the way...

 

I looked at Babbits on-line diagram, and it doesn't look too bad.
thanks for the heads-up! this isn't as bad as i thought.

 

i have a 2003 z400 and one of the 2 bolt on the lower swing arm has broke and it wont let me pull the sprocket side of the axle back havent looked at it yet but i was wondering if u hade a idea how to fix it
