Odometer Adjustment

I recently did the same thing when I swapped instrument clusters on my 89 
4runner.  I VERY GENTLY pried the speedo needle off from the front. I can't 
remember EXACTLY what it looks like in there, but you might be able to take 
the odometer assembly off without removing the needle.  But, either way, the 
needle does come off pretty easily.

Once you get the odo assembly off, on one end off the spindle that the 
mileage wheels turn on, there is a SMALL circlip.  If you take that off, it 
takes the pressure off of the wheels and you can separate them and turn them 
individually.  (AND YES, I DID TURN THE MILEAGE (KILOMETER-AGE) AHEAD ).

This knowledge also came in handy when I added 31x10.5 tires.  I measured 
the rolling circumference, then working backward from the tires for a given 
speed, I could calculate the RPM.  Then while driving at the proper RPM, I 
took the speedo needle off and repositioned it at the correct speed.
GOOD LUCK

When I swapped mine, I asked the guys at the junk yard to fix it for me.
They looked around real nervously, and took it in back to do it, but
they did it. When I looked closely at it, I saw marks on the plastic
that holds the transparent cover on the front, and scratches on the 
number dials. I think they popped the cover off, then rotated the dials
with a sharp pointed instrument (like a knife blade or scribe.) I was
afraid they might have broken it, but here we are, a year and 25,000
miles later, and it is still working fine. I think you will have to
remove the gauges again to pop it open.

PS - I'm proud of the fact my Toy has over 225,000 on it, and I saw
no reason to pretend it had less.

Well, the guys at the yard I bought it at had no clue - they just tried to 
find one close to the mileage, and that's the highest mileage on they had.

Well, I pried a bit, but it didn't come off real easy, so I didn't want ot 
break it before I tested it out and made sure it worked (I did spin the 
speedometer to make sure it worked before I started messing with it, just to 
make sure I'm starting with a working unit)  I guess I'll have to pry a bit 
harder.  I'm thinking of using a pair of wire strippers, and place the 
needle's shaft in the hole so I can pry evenly up on the needle.

Yeah, I knew how to do it once I got the thing apart, I just didn't want to 
break it if toyota glued the things down or something like that.

Interesting - but your odo would still be xx% off for every mile driven, but 
it might be a way to make slight compensations for age/wear on the speedo 
(i.e. gets older - registers a bit lower?)

THANKS a lot for the response I knew someone would have done the same thing 
I'm wanting to do.

I had my speedo checked at the speedo shop and they said that they do   
read slower with age.  The speedo is run on a magnetic drive.  Basically,   
the cable is attached to a rotating magnet and the needle base is a steel   
wheel in close proximity.  The needle base becomes magnetized over time   
and it reads slower.  The odo is all gears tho and does not degrade.

As far as wanting to register actual miles, I agree.  I get a giggle when   
I look at the 165K on mine!  I wouldn't want to replace it with a younger   
model.  Of course, I use the same line with my wife!  She's 41 but   
doesn't look a day over 40!  :)

Well, it's real easy on mine - it's exactly 51,003 miles off. (I simply add 
51K miles to get the mileage, but right now as I drive I've got one of those 
oil change stickers staring at me saying change your oil at 211k (they give 
the stickers out for the do-it-yourselfer's with the purchase of the oil at 
Western auto.)  I guess, I'll make a note of it, and just adjust, or if I'm 
real bored, hook up the drill and let 'er rip off 51k.

>from the "Idiot light" sender to the "Guage Sending unit"

Already got the unit in, but the cheapest place around here was $21 for the 
pressure guage sending unit.  Most places wanted around $40 ! and believe me 
I looked around when I heard $40!

Well, the concensus is that the needle does come off with a bit of prying, 
and the higher mileage is a tribute to the fact that toys are a real tough, 
long-lasting truck.  Oh yeah - and the high mileage is a giggle to look at 
when you figure how far they have travelled.
