I spent a good bit of yesterday working on my truck after the Metberry run, got a whole bunch of things done but also came up with some new things that I have questions about. I took pictures of most everything.

1. If after I turn the engine off I hear a hissing coming from the brake booster, I'm assuming that means it's leaking and I need a new one. Confirm? EDIT: I don't think so, I think I'm just paranoid :D

2. I'm getting a dead steady 14.5 in. Hg vacuum at idle. Assuming that's good given the brake booster is a source of lost vacuum. That should be pretty dang good for this altitude, brake booster is fine you paranoid sucker

3. Pic 1 - on the intake manifold, what mounts to these two threaded holes? EDIT: MEH

4. Pic 2 - on the driver's side fender, forward of the vacuum valves, what is mounted on these two threaded holes? EDIT: smog pump expansion/separation chamber (post 3).

5. Pic 3 - on the carb, what is this sensor/wire below the sightglass? Mines' not hooked up to anything. This might be a feature of the 9/77 - 12/78 Federal carb, but I don't know what it is. EDIT: Yes it is a feature of this era carb - it's a manifold temperature sensor that feeds back to the EGR system for those years. Not applicable here.

6. Pic 4 - I have a fully electronic ignition on a system that originally was not fully electronic. These two green plugs by my igniter are not hooked to anything, and I'm wondering if they are supposed to be hooked to each other? The plugs aren't exactly a matched pair. EDIT: I think so (post 4).

7. Pic 5 - What mounts to these three threaded holes on the passenger side fender? EDIT: a thread on MUD and here does not yield any 100% definitive answers - my truck is different from others with regard to the horn relay, washer bottle, etc. It may be to mount a washer bottle on a non-USA Cruiser, and Toyota may have used the same bolt hole pattern on bother fenders for interchangeability.

8. On my starter (sorry picture kinda fuzzy), the wire on the starter that's not hooked to anything, in the FSM says it's supposed to go to the coil. Is it supposed to connect to the wire on the lower left coming out of the wiring harness? EDIT: Yes and I did and it didn't appear to change anything, but I'm running with it :D

Sorry, I know it's kinda vague, but if someone with more or less original stuff on their truck (anytime around a 10/76) could check out a few of these things for me that would be great. Or maybe I could come look at somebody's truck sometime? Thanks guys and gals!

#5: evidently I'm missing the other half of this wire somewhere...but maybe 10/76 didn't have a provision for whatever this is?

http://forum.ih8mud.com/attachment.php?attachmentid=57733&stc=1&d=1140030415

maybe it's a cooling fan sensor?

The booster has a check valve between the booster chamber and the intake manifold. Either the check valve is leaking or more likely the rubber grommet that mounts the check valve in the booster.

Try plugging the booster hose and see if the manifold goes up much. I doubt it.

The two holes on the intake manifold had part of the EGR setup mounted on it on my 60 - I think, or maybe it was a PCV tube?

The sensor under the carb looks like it might be a vacuum switch - part of the smog system that reduces back fire on decel.

7. Pic 5 - What mounts to these three threaded holes on the passenger side fender?

Oooh...Oooh...Oooh :D

Not positive mind you but the front left bolt (furthest up on the fender, closest to the apron) is where my horn relay is mounted...

See here --> Horn relay thread (http://www.risingsun4x4club.org/forum2/showthread.php?t=4478)

You're always welcome to come by and compare 40s as well, although not sure a 12/74 is close enough in age and mine is missing a lot of stuff :hill:

#3 - I looked at Reuben's Cruiser and there is a little bracket that attaches to the intake there - Bruce is probably right is has something to do with EGR/smog, probably one of the brackets that I removed when I took my smog pump out.

I guess this is a fitting place for a new question, but first I don't want you all to laugh at me for my duct tape "fix". I was just trying to keep cold air from coming unhindered into the cab of the 40 temporarily until I could find a better solution. So there are a couple holes where the heater hoses go through; what are the other two holes under the duct tape for? I know you can't see them, but they're about the same size as the heater hose holes, only they're oriented vertically and have a very small separation between them (about 1/8"). Does anybody have the same thing or is it just me? :confused:

Nope, no power steering on my '77 (originally). I'm thinking it held a bracket or something for the smog pump/emissions stuff...

What about steering for a RHD Cruiser?

subzali
12-03-2009, 09:11 AM
no, there are no captured nuts on the firewall for the base of the steering column. Since RHD and LHD tubs are different (depressions for fuel tank, different holes in firewall for brake and clutch masters etc.) I wouldn't suspect this to be an option.

referring to post #3 that thingie (IIRC) is called the ABV (anti-backfire valve) it hooks from the air pump to the ABV then to the air rail. they are quite rare.

Above and to the right of the accelerator pedal – just left of the defrost hose. There’s a bolt and some kind of hose it’s holding – what do you think that is? 1976 FJ40.

Who needs ARB's? :confused:

I replaced mine on one side when I rebuilt my heater (old hose disintegrated). I used some of that generic clear tubing you can get at Home Depot.

Ahhhhh......the cowl vent. I knew the rear heater hoses are usually on the right side but these late model 40's are so technologically advanced that I made a suisumption.....didn't even think of the uber modern cowl vent....

subzali
05-24-2011, 01:30 PM
I'm having trouble finding if a '77 is supposed to have the vents/drain tubes as well, or if it stopped in '76 (which would explain why Jacket has one and the pictured '76 has one). Anyone know?

wesintl
05-24-2011, 02:11 PM
anything with the cowl vent should have them. so basically all late models...

I am going to state the obvious that Wes alluded to. If you don't have a cowl vent, you won't have cowl vent tubes. 1965-9/77 had cowl vents.

Couldn't find a recent pic:

So...if you don't have the drain tubes in place the water just dribbles down wherever it wants to? I don't recall ever seeing these on either my '76 nor my '74 40...Now I have to go look :)

10/76 FJ40 - no cowl vent, no hole in the driver's side floor/firewall for a hose to pass through, but there is a hose on the passenger side :confused:

My 1978 FJ45 (12/77 build) does not have the vent. My 1976 FJ40 (4/76 build) does, and it has drain tubes, but the vent does not open. My 1971 FJ40 (3/71 build) does, and it has drain tubes, and the vent opens. Of the 3 versions, I like the early one the best. It gives loads of fresh cool air, but doesn't blow right on your face like the later heater boxes do.

More questions to follow-up with the most recent progress:
I got some time to check out my FJ40 the other day.

Does anyone know what this bellhousing "boot" - part no. 35 is? It's rubber, popped out of the bellhousing when I poked it, and is deformed and won't go back in now. It acts as if it's too long for the hole it's supposed to go in, and buckles when I try to press it back in:
http://www.sor.com/sor/cat018b.tam

Also, I noticed differences in my brake calipers that I never noticed before. One of my "anti-rattle" or "anti-rust" springs was mangled (like on my Tundra, which I discovered a week ago). When I dug in more, I discovered that the caliper on my passenger side uses individual hairpin cotter pins to secure the brake pad pins, whereas the driver's side uses a long wire to secure the brake pad pins on that side. The passenger side caliper has no provision for the long wire, like the driver's side. So I have two different calipers at some point :confused: The casting numbers are the same, however.

nuclearlemon
08-30-2011, 04:46 PM
the boot is just to block off the other side of the bellhousing. there's openings in both sides because the bellhousing is universal for forks on both left and right sides. like the fork boot, it tends to soak the grease up and get useless. you can run without it, but it's good for keeping crap out.

the caliper indicates late 75/early 76 production. they used cotter pins for that period before going to the one piece pin. i've run them before with no issues. may have come off the pig that "dad" parted out. don't remember tho.

subzali
08-30-2011, 04:49 PM
Cool, thanks Ige! I think the calipers have date stamps on them, correct? If I read them correctly, the casting dates are pretty close. I'll check and post them up here. I wasn't worried about them not working properly, just was curious that they were different. Looks like my driver's side pads are going to need to be replaced before too long as well...

subzali
08-30-2011, 08:46 PM
Casting numbers on both calipers is S128.

On the driver's side...
Outer: 6 53
Inner: 6 59

On the passenger's side...
Outer: 6 52
Inner: 6 5R ??

Mean anything to anybody?

Ige, do you know if my 40 ever had air conditioning? There are two extra holes in the firewall that I've never been able to figure out, but looking at aking's '82 I think they might be in the right spot for someone to have put air conditioning in, or at least thought about it.
