18RG info and specs need 2tg and 3tg

[scootaphill]

when im not feeling soooo lazy and the novelty of a supercharged V8 has worn off(this may never happen by the way) i will have a look and post my 18R-GEU AFM TPS ECU part numbers for referance also

[3t-RA40]

Bring back an oldie, I've done the search and I couldn't come up with what I wanted.
Is the firing order for a 3tgte 1-3-4-2
Cheers,
Neil.

[Celica RA45]

most 4 cyl motors are 1342 in the firing except your local ford kent motor i think

this is information for the T series engine posted by the ever legendary river
it also confirms 1-3-4-2

Yep, just as I thought I'm as blind as a fruit bat. I just gave myself a good talking to and won't do it again.

Very early 2R Corona motors were 1243.

just digging this thread up for clarification on camshaft bearing torque specs....

... reading the green book as im assembling mine now, it indicates (in a pisspoor fashion) that the no.2,3,4,5 camshaft bearing caps be tightened to 74-86ish ft-lbs, and the no.1 camshaft bearing cap be tightened to 10-16 ft-lbs!!!

WTF????!?!!???!!1

JUST LOOK AT THE PICS:

the front cap isnt load bearing i beleive

[The Witzl]

but.... 80ft-lbs?????

[barned01]

just grabbed my book thinking...."wow golly gosh never noticed that before"
however on mine it says

fig 5-68 tighten each cap nut a little at a time to the specified torque in the sequence shown in the figure: (figure shows front cap first, then back cap, second cap, fouth cap, third cap)
tightening torques 1.6-2.2Kg-m (12-15ft-lb)

fig 5-69 then, install number 1 bearing cap (hold on they told me to tighten that down in fig5-68...what's going on there)

fig 5-70 tighten cap nuts to specified torque
tightening torques: 1..6-2.2kg-m (12-15ft-lb)

my edition is the 10th issue i think dec 8 1982 publication number 98196E


It is interesting to note that fig 5-68 say tighten in this order and it includes the first cap, then fig 5-69 say to install the 1st cap, then fig 5-70 kind of repeats 5-68 and says to tighten cap nuts to specified torque again.

another place in the book specifically mentions to tighten caps 2 to 5 then go back to 1
fig 3-60 (3) install the number 2 to number 5 camshaft caps. face the arrows towards the front
(4) gradually tighten the bearing caps in 3 to 4 stages in the sequence as shown (and to help there is NO numbering system on the picture but we assume 2-5-3-4)
torque 1.6-2.2 kg-m (12-15 ft-lb)
(5) then tighten number 1 bearing cap to 1.6-2.2 kg-m (12-15 ft-lb)


so somewhere along the lines they kind of got a bit confused for 5-68 to 5-70 i would say in both our books.
I used 3-60 in my book (ie caps 2-5 to 15ft-lb and then cap 1 to 15ft-lb)

[Steve M]

The second edition book states (fig. 3-60) that the 2nd-5th caps are to be tightened in 3-4 stages to 12.3-16.6 ft.lb.
After those are tightened, the no,1 cap is to be tightened to 8.7-13.0 ft.lb.

In figure 5-68 it has caps 2-5 being tightened in 3-4 stages to 12.3-16.6 ft.lb and no.1 bearing cap being installed after (no tightening torque listed in this figure).

Basically, I think your thoughts were correct Witzl, perhaps there was a typo in there for the tightening torques.
Who ever wrote your version got the figures mixed up with the 16R/18R cylinder head tightening torque as they are listed at 10.0-12.0kg/m.

Has anyone else noticed that the figures 5-35 and 5-36 (checking 18R-G valve grind) are not actually photos of an 18R-G head, the water ports are wrong and the spark plug position is not correct either.

Steve,

thank you again my friend for confirming that i am not insane and was right in thinking these torque settings were just a little erroneous.

I ended up tightening as per what your book says steve.

I would like to get my hands on the efi book too, but also the emmission control manual and the emission control computer.

I only know one of the specs for the EFI kit, that's the details of the TPS/throttlebody and how it compares to a 5ME or 22RE (late???) version.

The 18RGEU TPS I have (89452-14010) has its first stage at 1-5 degrees open (same as 5ME early) and its second stage at 20 degrees open (5ME early has second stage set to 60degrees open).
The 18RGEU TPS has 18.5 written on the rotor, the 5ME TPS (89452-14020) has 58.5 written on the rotor.
I reckon if you could find a "big square type" TPS with 20 degrees written on the cover plate, you would have a direct replacement.
Anyone able to read their 2TGEU/3TGTEU TPS numbers?
Both 18RGEU and 5ME models looked at were three pin type.

18RGEU throttle body size (p/n 22210-34070) = 60mm (5ME early p/n 22210-43270 is also 60mm and has same bolt pattern. Linkages on wrong side though).
22RE throttle body (35130-5J16) is 55mm and uses four pin TPS 89452-28030. Bolt pattern is same, TPS not compatible with 18RGEU loom. Linkages on correct side though.

Time to resurect this thread. The 82/83 Supra 5MGEU TB's (P/N is 22210-43101) share the bolt pattern, size and the linkage is on the proper side. A spacer need to be used or the plenum/throttle linkage need to be ground, since they hit (I'll post a pic when I get one). Linkage/cable setup is going to be a little creative, but I'll figure it out.

(P/N is 22210-43101)



Oh, and is this the kind of diagrams you were looking for?




Steve, with your permission, I'd like to copy this post (with your quote) to the 18RGTE thread.
