Steering gear bolts torque - different values, why??? (1 Viewer)

[Lukasz]

Hi, While checking the torque for mounting the steering gear to the frame in my rig I realized that there are different torques in Haynes (122 Nm) and RM184E (142 Nm).
Do you know why, and which of these two is correct? The RM184E is from Jan 1980 but in the supplement from 1992 (RM315E) there is nothing about this. For comparison printscreens from both books.

Your first picture shows leaf springs. I don't think that is the right vehicle. My manual for a 1996 LX450 shows 142 Nm.

Haynes manual is for the LC 60, 70, and 80. In front of each section there is a list of torques and sometimes they are different for different models but sometimes there is a single value, so I thought that this meant that it is identical for all three. Based on your information this is incorrect. So I will tighten my bolts to 142 Nm.

Might I also ask you to check the torque of the banjo hose of the front brake (I found 23 or 30 Nm but maybe this depends on the version with or without ABS / my is without),

and bolts of intake pipe (this with the "TOYOTA" word) of the manifold (I have 20 Nm but it looks to me too delicate for the size of bolts).

I find the (freely available) factory service manual to be a better reference for torque values than the Haynes, etc.

Do you mean this particular RM184E?

It would help to know what model/year your truck is when asking for information. That should be added to your signature.
I would never trust Hanes/Chilton/whatever for accurate information. They very often confuse models/years.
As stated earlier, download the correct Toyota manual for your vehicle from the resources section.
FYI, both the 1991 FSM and the 1996 FSM call for 105ft/lbs (142 N/M) for the 4 mounting bolts/nuts and 130 ft/lbs (177 N/M) for the pitman arm nut.

I had a Haynes manual for the 80 series. It had errors and contradictions all through it. I junked it ASAP when I found a genuine FSM.

they are a decent practical guide, but far from perfect

You are right, I should have presented my truck after joining the forum. My LC80 is from 1993 and has an HDT engine and LUB (some photos below).
I am really surprised that Haynes is not that good but it makes sense that the general manual is simply too... general. So, is the RM184E the proper one for my car, and RM172E for the engine?

FYI, the Haynes manual and the Gregory’s manual are exact copies of each other. As others have said, One Haynes manual is for the 60/70/80. There is another Haynes manual that has Diesel in parentheses. I use them as “fill in info” for the FSM (pictures, some step by step, etc…)

 

[Lukasz]

And which FSM do you use for your 1990 truck? RM184E, and RM172E for the engine? Or something other?

 

[CharlieS]

OP's signature says 1993: LC 80 1993 HD-T LUB

Here is a link to one (of several) sources for FSM that covers the 1993 80 series. The engine may be different, but for something like a bolt torque on a frame mounted component, I think you could feel pretty good about using it as a reference.

FSM - 1993-1994 FZJ-80 Updated and Combined FSM

IF YOU ARE HAPPY WITH THIS FSM PLEASE RATE THIS RESOURCE 5 STARS! Revision 05 has been uploaded, check out the update I posted detailing the new features added. The previous version of the 93-94 FSM had confusing file names, ridiculously...

Thank you for the suggestions. I already downloaded the pdf (and some others from this thread). Yeah, they are much more specific than Haynes and certainly will be a reliable source of information for my forthcoming repairs.
