Bolt specs

Merked98

Hey all, I have done some searching, even called the local honda dealer and I cannot get the specs of the torsion bar adjustment bolt for an '84-'87 wago. If anyone can find the specs that would be great! Thanks in advance!

90111-sb2-003 is the bolt part no.

If you don't get this info. 3 ways: read the number on the bolt head(e.g. 10).measure the bolt length ,thread pitch(e.g. 1.25,1.5,1.75 )& diameter.Some one here can probably cross-reference the torque .It'll be close enough.Most shops probably just tighten them by feel.
Another way is to check on the web for a metric bolt torque table.

That bolt won't have a torque spec per se, as it's used to adjust the ride height of the car. If you go to a particular torque spec, you might not end up at the required ride height. If however you are looking for the actual dimensions of the bolt, sorry can't help.

I thought that bolt only held the the torque tube in place.Isn't height adj. done byspline shifting?

There is a large nut that is used to adjust the ride height of the car. It's a minor adjustment, but it still raises/lowers the car about 1 1/2" or so. If you want more, then it's as you say, re-spline the torsion bar, but that's a rather coarse adjustment.

there is a keyway on the splines so it only goes in one way. i dont want torque specs. you loosen the nut on the small little bolt to lower the front and you tighten it to raise it. its a 2 min adjustment. it has a nyloc nut on. im getting a longer bolt and its my daily driver so its hard to take out the bolt and go to a store. but ill get a thread pitch reader and a micrometer and do it myslef. thanks for the input though

You need to grind down the wide knotch/spline on the torsion bar so it'll go in in a different position. Been there done that. I started out with the 3rd gen cars back in 1986, and raced those for a while before graduating to the 4th gens in 1993. There was also a special kit from a company called A-T Engineering that relocated the attachment point of the lower control arm onto the knuckle to lower the car about 1 1/2" and then you could fine tune the ride height from there using the torsion bar adjustment. This was an alternative to the keyway grinding thing on the bar itself.

awsome! well i knew about the knotch but i guess i didnt think of grinding it. thanks. but a longer bolt could also do the trick and less work.
