H55f on 2F help!

[Casey E]

Yep, crawler under and take a picture. Most likely stock splitcase. Great transfer case.

Something is weirdly wrong. Because you are way to high even if the gears have been replaced with 5.29s.

You sure you're in high range? Really sure? I'm going to guess you are in low range and have the stock 3.70 gears.

There are not other transfer cases with different ratios that magically fit. And even if the gearing was changed, the high range gear changes only about 10%-ie not enough to explain your problem.

Don't spin a 2F much over 3K for long if you want it to live.

I would go back to the basics.

Take pictures from underneath of your set up and take a picture of your shifters inside.

 

[Casey E]

Crawl under and grab the front drive shaft and see if you can spin it by hand before you drive home.

Anybody have a shift pattern for the transfer case? I'm going off what the knob says and now I don't believe it after playing around with it.

 

[Casey E]

That's the correct one. Take picture under neath and make sure front driveline spins.

 

[Cruiserdrew]

THe pattern on the knob is correct but look underneath and see if the shifter is shifting anything. It really sounds like you are in low range and don't know it.

It's possible the linkage is disconnected, but you're going to have to get under there and have a good look.

 

[Casey E]

Cruiserdrew is right. The math shows you are most likely in 2low. A 5speed in 2low with stock gears and 31" tires is about 3,800 rpm at 55 ish.

 

[Cruiserdrew]

That's the correct one. Take picture under neath and make sure front driveline spins.

And whether the front drive line spins may not tell him much if the shift linkage is wonky. Meaning, if the shifter gate plate was removed, you could be in low and not in 4 wheel drive.

 

[Tylerh84]

That's the correct one. Take picture under neath and make sure front driveline spins.

The front driveshaft is free.

So after playing around with it I can move it to the right then forward a bit more. I'm going to try that after work and see if that changes anything. But I have been in 4 LO and it was definitely a lower ratio than when I am in "2HI"

 

[Casey E]

Sweet, now we need pics of your ride and welcome to the cruiser community. Don't be afraid to ask questions.

 

[Cruiserdrew]

Tyler-It really sounds like the PO removed the shift gate plate. With the gate functional, That's OK and done to allow you to use 2Low. That can be useful on boat ramps and stuff if you need to maneuver but need the grunt of low range. It is also possible that the shifter or the lver arm it pushes on on the transfer case have come off.

I have also seen problems when people try and re-use an early shifter pre-85 to shift with an H55 present by welding to the linkage but it's a hack and never really works well.

Post pics of what you find underneath. You will need to remove the skid plate.

 

[Casey E]

I would say easier to sit in cab and pull the shift boot off and have a look if someone moded it.

FJ60 2lo with stock transfer case EASY mod

This thread explains what most likely is going on.

 

[Tylerh84]

I still gotta take the boot off and look at the gate but there is definitely something up with gearing.

So here is both in 5th at 2500rpm
First pic is 2HI
Second pic is 4LO

 

[Tylerh84]

Shift gate has not been modified. (See pic2)
And here is the back of the transfer case. (See pic1)

 

[Casey E]

Wow, 5.29 gears at 55 with 31" tires is about 2300 rpm in 5th. I'm not a gear guy so not sure if you can even get 5.29's in a 60 rear.

 

[g-man]

circled in red is where the rear wheel to 4 wheel shift shaft is located on the pass side of the tcase. When you move the shifter forward the shift shaft moves back and into 2 wheel (rear drive shaft engaged only) . the blue circle is the high/low shift shaft. this is engaged when you move your shifter side to side. High is to the left and low to the right. The green circle is where the shift gate is mounted on the side of the transmission. You're shifter should catch and sit in the gate when it 2h at the top right position. If you put your head near the starter motor you should be able to see the shift gate.

 

[Tylerh84]

I am definitely in my 2HI. I have a considerable difference between 2HI and 4LO. (see pics above)

Here are pics of the lever position for each.
1st is N
2nd is 4HI
3rd is 4LO
4th is 2HI

 

[Tylerh84]

Wow, 5.29 gears at 55 with 31" tires is about 2300 rpm in 5th. I'm not a gear guy so not sure if you can even get 5.29's in a 60 rear.

Remember this is the speed of the tach which picks up on the back side of the transfer so the diff gearing doesn't matter .

 

[Casey E]

Well, I'm guess diff gears at this point. Time to jack up the rear axles and count tire revolution's against pinion revolution's. This will give gear ratio.
