Memory Prompt ? FJ60 Steering Gear.

I know this is buried in the shop manual or its buried in my mind somewhere... As i recall does the steering gear have a neutral center postion where you have (for example) three full turns to stop point left,then back to center and then three full turns to the right. I was sure that you were suppose to center the steering gear when you took one off and got ready to put in back on.

I seem to have good bit shorter turning radius (either left or right) I don't recall as i write this, but it seems I have far more "turns" of the steering wheel either left or right as opposed to the other direction, which is limiting my turning for no other apparent reason. I don't think its hitting the stops...I think its in the steering gear. basically its seems as if I'm running out of turns in the steering gear.

I had the gear rebuilt one time and swapped way back when and since I did not do the rebuild I'm not sure if the steering gear is at its proper neutral or center position (wither steering set straight ahead).

Does this make sense? I recall reading in teh past in a gm shop or other manual about importance of getting the gear to the neutral position before re-installing...of course we just bolted the thing back in and that may be my problem I'm describing.

IIRC...

If you look on the bottom of the sector shaft on the gearbox, there is a centering line that should line up with a line on the pitman arm when pointing straight ahead. This should be "zero".

That said, I don't think mine has exactly the same turning radius in both directions and mine is centered.

Yea...I'm lined up on the mark...but think about this...that mark is only relative for one 360degree rotation.... so what if you are two or three rounds to the left....the mark will still line up. I may be wrong and confusing some some history...but I seem to recall that the gear itself on has so many cycles it can turn to the left or right from the center position. Maybe I'm full of it or something or my mind is merging unrelated facts...I'll have to force myself to go back through some tech references.

see step 3 page 5 of what I just came across on web search.... Good article I don't recall seeing before

Need help!

Finally got TH carb

The good: starts when I crank it.
The bad: idle races all over the place, tries to stall & won't idle smoothly. Eventually dies.

Things I've done:
-new fuel filter
-new plugs
-checked dizzy cap & rotor button ok
-pulled valve cover & checked valve clearance (intake .20mm exh .35mm) ok
-removed double intake man gasket, now single)

I'm almost ready to sell this damn thing or blow it up

 

[radioridge]

vacuum leak?

 

[sk8salomon]

vacuum leak?

Thx for the call. Notice the bolt above. I've changed the washer by cutting down so it makes contact w the intake first. Flange on the new 6-1 header is thicker so that may be what's going on.

 

[FJ60Cam]

Is it just at idle? If you give it gas does it run ok?

Nope, rpm all over the place. I maybe have 25% control, the rest is the 2F butt goblins

You have a vacuum leak and I would be checking the intake to head . I use brake cleaner to find vacuum leaks but be careful with it . I had a problem with the header and intake mating on my sons 40 when I put a header on his . Finally took them down to the machine shop and had them resurface to match . Got them back and problem was fixed . Just one of many ideas . If I lived a little closer I would come and help you , I know how frustrating it gets . Good luck buddy .

 

[Elbert]

you can use carb cleaner and various other things too...to help find vacuum leak. You spray it in short burst around where you think there might be a leak...and if the idle changes based on that spary point....you have found a leak in that area. Then look to figure out why the leak.

Don't turn into the human flame thrower though.. Don't have your body or face right in the area where you spray (for obvious reasons).

Well after 2 different manifold gaskets, bolts & shims we finally found the problem.

Blown head gasket!

 

[FJ60Cam]

Well, poop. Have you pulled the head yet? Where did it fail? Any loss of or mixing of oil/coolant?

 

[jynx]

Dang, well that sucks.

dang.....well, clearly the fix now is a V8 Swap!

No but I saw water bubbling out between head & block passenger side. Have not done comp test yet

 

[FJ60Cam]

I got lucky and mine failed between two cylinders. It only required a new gasket. No machine work or anything.

I did get the dizzy recurved for a desmog after that though.

I'll keep my fingers crossed for you.

 

[sk8salomon]

Thanks, I'll post up pics soon. Not sure I can get all this done before Gsmtr

 

[Elbert]

head gasket failure bites..... if you have coolant in the oil...drain the oil and make sure you don't run the engine. Change the oil and filter more than once when you get things back together. Coolant in the oil kills bearings.

Really crappy for the timing on the failure....right about when you had it fixed...my luck too, I had something similar happen one time on a pickup I owned...I nearly put a few bullets through the engine to make myself feel better.

I'm glad I spent the $$$ years ago for the FSMs!!!
