Hi,

I'm rebuilding a U151E from my 2006 Toyota Sienna and I can not find the torque specification for the bolts that have cover plates for both the upper and lower valve body halves.

You may see an example of the cover plate in the first image of the link above. The bolts I am asking about have the smaller bolt heads.

The Sonnax Zip Kit Instructions do not mention removing these plates, but I can not get all the spool valves out and I am concerned the paper gaskets will be damaged during cleaning. Furthermore, I have new gaskets.

Also, the Toyota Manual does not describe the tear down of the valve body except for solenoid replacement, so the torque setting is not listed.

There's a couple guys on You Tube that do these and I think they tell the specs for VB. Just search and do a little watching.

YouTube was a great suggestion since I needed to know whether the install the valve body with ATF or dry. The videos indicated dry.

I was able to deduce that the torque is90 in-lbs. This bolt is identified as an 8T-5, but the torque value is not in the chart. However, 90 in-lbs is used for anther bolt in the valve body from the instructions provided by Sonnax. Furthermore, there are only 3 different torque values such as 25, 48 and 90 so I feel these a settings for classes of fasteners.

I used the torque wrench and set to 85 in-lbs and tightened the already tight bolts (since I had not removed them yet) and the wrench indicated they were tighter than 85. Setting the wrench up to 90 in-lbs and tightening provided a small tightening but I figure this is the error in the wrench so within +- 5 in-lbs.

Therefore, I am relatively confident 90 in-lbs is the preferred value.

Thanks so much for the comments.
