Idle solenoid appears cut? (1 Viewer)

[Dclowd9901]

Hopped in my 60 last night to go to a movie. It was running fine all day, but this time I go to start it, it idles low and dies. Can’t keep it running, look on here and suspect the idle solenoid. Pretty familiar story.

Weird thing is, I pull the solenoid out (it’s not clicking with power, but definitely taking power), and it looks like someone took a dremel to the needle or something. Why would it look like this? Is it possible at all for it to have sheared inside the carb? Is there any practical reason for the PO to have done this?

First photo is of the solenoid itself, second is a snake cam pic of its cavity in the carb.

Looks like the end broke off. Pretty sure from memory that there’s more to the end of it than stopping at threads. It probably has sheared. You’ll need to pull the air horn (top section) off the carb.

 

[Dclowd9901]

Oh yeah, there’s definitely supposed to be more. From pictures I’ve seen, the normal, unpowered position is a piston head extended. But looking inside the port with the snake cam, I’m not seeing anything that looks like the part that broke off (which would at least have a rod still on it, I would think, given how this valve is “broken” off

What it’s supposed to look like, minus missing the o-ring. From the pic, it looks like the rest may be stuck in there, but it also appears it was cut off. I dunno!

I’m thinking it was cut off because since I’ve had the truck it’s sporadically diesel’d on shut off, and I’ve heard some people do this when their cut off solenoid goes haywire.

I just did a vacuum test and it showed I had no vacuum whatsoever. On doing a fog leak test, I saw a lot of fog coming out of the top of the air filter housing (between the cover and lower housing) and between the air filter housing and carb. I did notice a gasket between the top of the air cleaner and base but I never noticed any gaskets or anything between the air cleaner and the carb. Is there supposed to be something there to help seal it up?

Yes, there’s supposed to be a seal there.

I had a carb I bought to rebuild a few years back snap off just like yours. Took me a bit to remember. I’m betting the end is in the carb housing.
Where’d you get the new solenoid from? You don’t want the cheap one from cruisercorp, it’s well known that it’s junk, China made. Matt’s is probably better quality.

Not having the proper connector is the pet peeve for me

i have never seen one except a OEM TOYOTA now DISC. come with a crush ring either and or the Correct Connector ?

not having a New crush ring can cause a Vacuum leak or not having one at all worse ...........

 

[Dclowd9901]

For the time being, I sealed the air cleaner and air horn with some adhesive weatherstripping I had lying around. Also threw some sea foam in the gas tank. That seemed to do the trick. It’s idling at 1000 rpms like it used to but I still think it’s leaky as hell all over that system and I need to get some new tubing.

Well damn, thanks for the heads up. Gonna cancel it now and get Matt’s. Thanks!

I would Not Run the Engine With A Fuel Cut Solenoid un-installed ?

in addition to a huge Vacuum leak Possible thing

Possibly having Foreign Matter Sucked into your carburetor in any way shape or form would be a unacceptable risk

for me

its simply not worth the risk ..............

I would Find a Rubber plug and cork it ,

or

new clean bolt same thread pitch & Diameter as fuel Cut and GENTILITY hand thread it only finger tight ...

till the proper FSM Based Repairs can be made

IMO ......

No worries; having assumed all those things you described to be true, I reinstalled the solenoid for the time being.

I suspect, however, that replacing the solenoid won’t be the end of it. I’ve seen parts sheer and snap before, the pattern on the solenoid denotes a rotational instrument that left barbs on the edges. My guess is this solenoid was cut because it was operating opposite of how it is supposed to, or it was operating ok, but they cut it because trying to meet Cali emissions requirements, and still getting the vehicle to start was too much of a challenge.

i just spec'd the Fuel Cut threads ,

There a very ODD size Not used anywhere else on a land cruiser or TOYOTA Vehical im aware of ?

8mm Dia. x 1.0 pitch

so running in a bolt is not possible ?

 

[ToyotaMatt]

i have never heard or seen a altered or Modified Fuel Cut ?

here's what TOYOTA says ..............

 

[ToyotaMatt]

 

[NeverGiveUpYota]

@mwebfj60 Marc had done some studying on running it w/o and a bolt installed if memory serves correct.

@mwebfj60 Marc had done some studying on running it w/o and a bolt installed if memory serves correct.

if so he either made the bolt or plug , or special ordered one from a place like mcmaster ?

i thought more on the topic later & checked my Extensive TAP & DIE set , iv put together

i dont have either a tap or die in that size , where as iv added many for special use applications like TOYOTA SEAT belt Thread pitch and dia. and the Choke cable retaining nuts i hand make too in my drill press


My Theory now is :

the Solenoid Failed , or stayed closed during attempted engine operation as if NO B+ was flowing through it

so the PO , removed it , chopped off the end to allow FULL FUEL flow at Running Time , But did not know

the consequences of those actions ?

u have to remember , back then only a few years ago , the Dealer was the only place to source a Fuel Cut ,


Not like today where " some " quality ones are being made outside JAPAN in South East ASIA out of Necessity

since toyota DISC. both Single Wire and Dual Wire OEM Versions


i am pretty certain a OEM one ran close to $175-$200 back in the day

so the Logic of Why now makes pretty good sense .........


i have a NOS OEM Single Wire Fuel Cut 21062-61010 , but neither that or the later 2 Wire are on the Toyota Global Price Tapes any longer ?

I purchased the NOS OEM Single wire back in High ScHool in the early 1990's

now it resides in NOS Retirement in my NOS Parts Reference Collection Mini-Museum .........
