I'm trying to find the internal hub from a 30 spline Aisin free hub. I suspect I'll need two. Anyone got a set around?

I started replacing my inner axle seals on the HJ60 and have found more damage than i expected. not sure yet what has caused it, but when I took the left hub apart I found a circlip from the feehub floating around. It came free, evidently, due to the inside edge of the internal hub being ground to a pulp.

I'm in Saanich. 778 430 5860.

is your c clip still on your birf.... u cant take off the housing of the asian hub off without removing the c clip.... is this what your talking about... ?? did the aisin free hub slide right off when you unbolted it ???
 
you can buy chromo internal hub gears for about 120 online... or just visit the guys at west shore spring ... they can get them in next day for the prices on the trailgear site no shipping...

I had a similar problem when I was an idiot putting mine together... so now I have a asin and a selectro.... I really need to pull the hubs off the axle I have sitting in courtenay. Did you blow 1 or both?
 
well, the good news is only the left side is damaged. the bad news may be the why.

last time i had the axle apart there were no circlips on the end of the birfield. so i bought two but when i reassembled the axle, the free hub would not fit over the birf with the circlip on. so i removed it and surmised that maybe there had been one of those tack welding jobs done to keep the axles inboard.

nope.

this time, took everything apart and cleaned them left side birf popped off the inner axle, as the little spring clip is missing. somehow the birf moved outboard or the inside of the free hub came in contact with something nasty. the damaged part of the free hub is a the piece that has 30 splines and the birf fits into it. sorry, no photos.

good news is Ken has a spare, maybe. i'll rebuild everything and then try to figure out why i can't seat the axles inboard far enough to fit my freehubs on with all the right circlips in place.

annoying and embarrasing to note that when I bought the truck the PO indicated it had longfields. well, i can't find Long marked anywhere on these things. bummer.

thanks for the input.

i may have spare spares, jjamison on island 4x4 keeps has some they are normally about 20 to 50 used, call rcu and sooke auto wreckers they are the same as the ones on all early toy p/u solid axles only difference are the colour of the piece you turn. cruisers are gold and mini truck is red. i will look tomorrow if i get a chance.

strange...you are putting the circlip on after the hub body part of the lockout right? (had to ask...:grinpimp:)

also, there's some birfs out there from some sorta transition year, that are slightly longer than usual.

there were hub bodies that were slightly longer to accomodate, and when I had some I had to make some 1/4 aluminum spacers to go between the hub body and lockout...because I couldn't find any of the transition hub bodies.

Don't think I could even get the lockout on there tho until I made the spacer?

Some had a special washer and a bolt in the end rather than the circlip. Still have the bolts and washers, I used to like them better because I still find those circlips to be a pain in the ass to get out.

none of this may be your problem, just random thoughts as the coffee kicks in.

cheers,

well, after a little more work tonight, i'm still perplexed. Ryan, thanks for the suggestions, I have wondered the same ref birf and axle length. and yes, i did have the free hub apart so i could fit the circlip on the end of the birfield. just when i went to bolt on the outer part of the free hub, the bit with the dial, i couldn't push the axle in far enough as the circlip was jamming against the inside of the dial body.

i finally realized tonight the axles were martacked 1 9/16 from inner end. that was with the 5.29 gears and the carrier they were on. I now have 4.56 gears and possibly a different carrier, which may effect spacing.

i decided to try to put the birf on with the stock circlip, but failed. tried zip ties, jubilee clips and screwdrivers. still can't.
figured if i put the birf back on in the stock form with the clips, tried it and it didn't work, the next step would be to grind off the martack weld, try it again.

but as the hour grows late with my frustration level, i'll leave it for tonight and see what others have come up against with the same thing.

i dont think that the gear ratio on the diff would change your spacing... the spider gears will still be in the same spot no matter gear ratio ...

i just put in a 4.56 that replaced the 4.11..different carriers.. .. no problems with the previous martack that i welded to the shaft...

now when i did my martack i tried what others had wrote on the forum ... most will say that its 1 1/2 inches.... tried that and didnt work... i ended up with just over
1 5/8 inch for the martacks on both axle shafts..

sounds like the martacks are off a bit... i sent you a pm about some spare shafts i have for a 60 series... if your interested...
 
Dont know if it the same problem or not but when i broke my selectro hub i went to the wrecker on Dunford ave and picked up some aisin hubs. When i went to install them the end of the axle hit the dial part and i couldnt tighten them up. I went back and went through their pile of hubs and found a set a little bit longer and they bolted right up.
 
were they hubs from a mini truck or a cruiser... could be in the FAQ section but didnt stub shafts on the birfs vary in lengths on certain years.. could be wrong...

bingo

just looked that one up. 178 mm should be the length. mine are 188mm.

hmmm

Oi, don't be givin' him the bingo, cast your eyes up at post #7..:flipoff2:



Pretty sure birfs from 40's 60's 70's and Mini trucks are all the same length, except for, a couple years in the 70's , 76-78 I believe, when the cruiser birfs were longer, and thus a total pain in the ass if you don't have the longer hub bodies....

The longer hub bodies are kinda rare, wish I hadn't got rid of mine, because both types fit in there...
 
guess the FAQ section on birfs is wrong then.... ..its @ the top of the page...

i think they were different lengths do to the knuckle housing??
no...yes... maybe.... worked for me when i put marfields into my axle with those six shooter knuckles.. and those marfields are for a mini....


Chris... forgot to ask what does the brass bushing on the end of the spindle look like... birf slides through the spindle...

No it's right, 76-80 cruiser birfs were 188mm, all after were 178mm. TLC FAQ - 9.2 Birfield Sizes.:beer:

I'd thought it was only a couple years, but I guess if it's 4 years, it could be called early disc brake rather than transition, but still. pretty much everything after 80 should have the same birfs in it

inner axle lengths are all over the place tho.

I've had mini truck birfs in my cruiser before...I think the shortside inner axle is even the same length, tho I'm not sure of that

( and sucks to hear chris, which I was remiss in not saying earlier....)
 
Gents,

Thanks for the suggestions, it arrives faster than I can get time to go outside, measure things, and try to reference it on the net.

I think I'll just get this pair of axles and birfs from Ken tomorrow and compare. spent an hour tonight waggling the steering around and trying to understand how much the axles slide back and forth etc as you steer. even considered just grind a new flat groove for the circlip to fit into 10mm inboard from the current one. but i know i'd fudge it, and the splines only go so far inboard on the birf, so i'll wait till tomorrow.

Adam, I'll have another look at the spindle, but I didn't note any damage yet. I was curious if the threaded end of the spindle had somehow pressed into the free hub and done the damage, but can't see how they would have connected.

Dan, I remember your comments about hubs, but I bet I was thinking about free wheel locking hubs, not the wheel hub proper, and misunderstood.

We'll see what tomorrow brings.
