View Full Version : my broken transfer case
06-21-2003, 12:26 AM
since i know we all like to see pics of carnage and destruction,i thot id put up a quick pic of my broken spicer 18 transfer case
as you can see,the teeth are completely missing on about 1/3 of the lower slider(low range gear). the intermediate gear is actually in not terrible shape,with only a couple of teeth being chunked up. the angle cut(high range) gears,including the input gear are fine. compared to number 1 and number 3,this one is actually in pretty good shape smile.gif pretty much every gear in those cases was missing all the teeth,with number 3 locking up completely while pulling me back to camp. :eek:
notice the 10 spline output shaft is fine ;)

redface.gif ouch!!!!! well at least you have a few backups.

kewl cause i was wondering about the output on a d20 which is the same 10 spline :/
need some new gears in there huh?

im tired of breaking them,so this time im installing a d20 in its place. i am curious to see if i continue to break gears,or if i start twisting off d20 tailsahfts,wich i understand to be a common occurence on d20s that are pushed hard with big tires ;)
the case pictured was assembled with 2.03 d20 gears,wich insinuates( to me at least) that the prollem is moreso due to size/weight of vehicle and tires,rather than the gears themselves,wich was a previous theory.id thot maybe i was breaking 2.46 gears since all of them that you find are 30+ years old.
ive also got quite a few d20 parts,so i can twist off a few output shafts before i have to put in a 205. im hoping to make the d20s last long enuff to get my 435/203/205 ready :cool:

YUK!!!! At least you got backups.... thats the best part... no money involved.... just time...
06-21-2003, 02:47 AM
yup no $$ involved,cept for some carb cleaner,a couple shift shaft seals,and a can of purple paint. ive been accumulating d20 stuff for awhile,and last year i got 3 spicer 18s at a scout swap meet at prices ranging from $30 to $50. i still have 2 coomplete scout cases,but theres no sense in breaking them...
ive got a complete d20,2 tailshaft housings,and at least 1 good tailsahft not in a housing,among other asorted parts tongue.gif

Hey...I thought the little tiny 258 couldnt break stuff like that :razz: So much for "No replacement for displacment....I like the 258, its a beast! :D

Ouch! Remember when I shattered my main output gear? It was last year. We all thought it was pretty strange then that the output shaft didn't break first. I have faith in the D20. I too have collected many parts for spares ;) .

mtn goat there was a time when i thot the 6 cyl was helping me keep parts breakage to a minimum,but the 258 breaks stuff just fine smile.gif
ya i remember that PC,it was strange that the input gear let go first.just goes to show how you cant always predict what will break...

An 80's 258 makes more low end grunt then an 80's 360 at low rpm's. So I say if anything it hurts you more :D Although in higher rpm's a 360 makes more HP and torque.
Seems like another reason for me to be hanging on to spare dana20 parts too smile.gif

Did you break that towing my old trailer?
06-23-2003, 12:47 AM
LOL,nope,broke it by bringing the revs up and dumping the clutch in 2nd gear in the middle of a hill to try and pop myself over a root at the top.
i have used the p*ss out of your trailer,tho,ive added it to the top of the "most useful things ive ever purched" list :D
i hauled over 300#s of weeds to the incinerator with it,used it to haul off a bunch of old skids at work,and even picked up a ton of gravel to spread around my ex-flower beds :cool:

scotty be glad you got extra shafts cuz you'll need them. i believe if you wanted the 32 spline output, that'll run you about $400-$500. it almost seems better to have an extra case like Rockwagon has in the back. a large PITA but you'll be mobile. ;)

yeah,the tailsahft housing is a fairly easy swap on the trail. when we go further away,i allready carry a spare transer case in the tow rig. ill prolly carry a tailshaft in a housing,and a complete spare case
at any rate,theres no way id spend $400-$500 to beef up a 20. ill stick 465/205 in there before id do something like that...
06-23-2003, 09:06 AM
that's a smart move. i'm hoping to go with a 205 later on as well.
i was woundering if a d300 was a good t-case
06-24-2003, 11:56 PM
its prolly stronger than the 20,but still not in the same league as the 205.they make a beefy tailsahft upgrade for it as well ;)
