Motor mount bolts torque specs? AT, back "dog bone"

[seatech30]

I'm planning to swap out all my motor mounts. I'm missing torque specs for two bolt types on the bottom/back mounts. See image in red. Part numbers are 90119-14139 and 90105-10301 if that helps. Thanks!

Side question, from my understanding of the documentation, it seems to be best to replace mounts in the following order, remove pass side, remove transmission side, replace transmission side, replace pass side, remove back/bottom, replace back/bottom. Is this about right?

90105-10301 - 29 ft-lbs

Can't seem to find torque spec for 90119-14139, sorry.

Thanks for the spec! One more down, so no worries. I may have to go by feel based on the size of the bolt once I get it out. I'll report back if I find any way to get a good estimate.

I may have that page of the repair manual at home (buried in the garage). I'll see what I can find...

100 Nm, 74 ft-lb. Same for AT and MT.

:O I need to get me one of those! Thanks a bunch!

I don't have a full book, just excerpts from when I had a TechInfo subscription. I'm not sure if that's even a thing for the Yaris...

[NYC-SE]

There was a post somewhere on here that had a link to a pdf Yaris manual. That's how I got mine. I'll see if I can find the link again.

Found it:

I was able to download the first link. The second link would let me view online but not download. FYI even though this is a manual for a second generation car most info is applicable to 3rd gen as well.

are you getting Ori mounts or OEM mounts?

Thanks for the link, I actually have these manuals from a while back, unfortunately they don't show all the torques for every aspect of car jobs, in my case replacing all the mounts. I went through all engine related ones and couldn't find the two torques needed.

However, I did find a spec sheet that shows you how to determine the torque for all bolts based on their size and pitch, so I'll be using that in the future for any other mystery bolts.

Edit:
are you getting Ori mounts or OEM mounts?
I went with the following parts DEA A4254, Westar EM-5930, DEA A4237, and 12364-21020 from Toyotapartsdeal which I believe is supposed to be OEM. I just wasn't ready to drop OEM money for something that many not be a sure fix. Had this issue with my old yaris and did all mounts twice with OEM from tpd and it never was resolved. If I see a difference, I'll fork the money when these go out. I haven't heard or seen Ori. I'll check them out, thanks!



Edit2: while putting my back seats frame bar back on, I realized the bolts used had a torque spec of 125Nm on the doc I mentioned, after some testing, I determined that those bolts were actually 42Nm (same as the seat belt bolts.) Just thought I'd mention it in case someone else makes the same assumption I did.

CrankyOldMan, just realized what techinfo is. I thought it was something for mechanics. I got the 2 day subscription, waiting for it to let me in. I think it wont take effect till midnight, though. [Scratch that, I got in, had to change password for some reason] Thanks!

I took off the engine RH side mount because it arrived first, but it didn't come with the bracket. I took it off the old one, it was on there good. But the repair manuals don't show the torque for this bolt (dead center under the mount cylinder.)

[I can't seem to find the section that you showed in your pick. Most of what I'm seeing is like what I already have.]

Edit2: Went with 50ft-lbf. Tried to go for 74ft-lbf, but felt like too much, didn't get there.
I did a trial on removing the ENGINE MOVING CONTROL ROD BRACKET and it seems the bottom of the top two bolts is going to give me a hard time. I'm guessing I can jack the transmission up? Will loosening be necessary on the other mounts or is there anything else I should watch for?

[CrankyOldMan]

I'd have to see a picture to know for sure which one you need, but that would probably have your answer in it. =)

[seatech30]

This is the one. I think I saw somewhere that mounts only last about 30-50k miles lol hmm.

Edit: I emailed the manufacturer, and they told me "30Nm ( 22 ft.lb )" somehow I don't think that's enough. I'll leave them at 50ft-lbf for now.

The stud that's poking out from the one on the right? I don't recognize that mount, but I don't think that the AT and MT have different parts. It's been a hot minute since I've looked at the 1.5 L mounts. What size bolt/thread is it?

I highly doubt that the Toyota spec for mounts is 50k miles. That's pretty crappy even by US domestic manufacturer standards.

No, I have the spec, 38ft-lbf, for the nut that goes on that stud. I'm talking about the bolt in the center. The mount is upside down, so that's probably why it looks off. Notice the bracket missing from the other mount. I just swapped that over to the new one. Went with 50 ft-lbf. Thought about doing 74ft-lbf but felt a bit too much while trying to get it there. Thanks for the help anyways.

The bolt in the center shouldn't ever be removed, as far as I know. That's the one through the damper/rubber part, right?

It connects the brack to the body. The mount came without the bracket, so I had no choice but to remove it to move it over to the new mount.

I already swapped the mounts. It went pretty well. Unfortunately the transmission mount from westar was not the exact same and was not able to install that one. I ordered some 3M polyurethane and gonna give filling the old mount a sho

Vibration didn't change much, even changed the exhaust holder rubber things, oh well.

Hey, did you ever get that hard to reach bolt out?
I just tried to change this lower engine moving control rod and bracket, but I couldn't get to that one hard to reach bolt.
