Longfield Install

[daves80]

Hi
I have just purchased and installed a set of longfield birfs and axles to my 94 model part time cruiser. before purchasing I asked about getting a short set to suit aisin free wheel hubs but was told that they are all one size and that they will fit but when I got them they are to suit the longer late model drive plate.s With the free wheel hubs if I pull the birf into its correct position using a spacer I can't bolt the hub up because of the length. I don't want to run late model drive plates because of the part time T/case I intend on keeping the aisin F/wheel hubs but am worried the stub will punch the dial out. What other options do I have? I could possibly machine a new grove and shorten the stub, I could make a spacer to fit between the F/wheel hub and the hub on the disk.
I am just getting ideas atm for the simplest fix, and want to find out other peoples experiancees.

some folks run one extra snap ring as the spacer (it's not as much of a spacer as you need, but if you spaced them out to what you do need...then you can't get the aisan hub on.

if you machine a new groove in the longfield does it void his warranty?

I thought Slee carried hubs that work, not 100% sure though.

Yeah,

I think the AVM hubs fit the longer axles.

Good to know... Guess that's the hub I'll be running!

Since I already have the Aisin hubs (running for 4 or 5 years now)....I'm curious to see how the birfs held up with one extra c-clip and amsoil oil. I know alia176 showed a lot of birf wear and oil leakage....i don't show near the amount he does...very little at all.

either way, i'm probably going to fab up a spacer for the aisin hubs...between using the extra c-clip and hub spacer, I should be right where I need to be. I would take out the extra c-clip and make the spacer thicker, but I want more "teeth" on the hub mating surface

later,

Insteresting thread since I have 2 part time 80 series .. why not simply machining the bierfield ?

Are that stronger I thought here in Panamá or in Australia the waranty ( counting on shipping cost ) not gonna be an issue ..

[daves80]

I ended up machining the birfield, was just a hassle pulling it all apart again. I can't remember exactly how much I took off but It was approx 8mm. Putting a spacer between the C clip and gear won't work with aisin hubs as the splines are too long. Even with shortening the birfield the splines still had full contact in the gear.

Did you take a picture of the final product .. . ?

How much contact . this may cause heat problems in the hub cap ? ( for friction )

[daves80]

Sorry, but I didn't take any pics. But it looked the same just shorter. I took the measurements from the birfield that I removed.

I must have miss understood your question about gear contact, I ment that the splines hadfull contact on the internal splines of the gear inside the hub, there is no rubbling contact that I can see. If it isn't shortened or the whole hub space out, when the axle and birfield floats out it will push the dial out of the hub I would guess, because when I assembled it originally and pulled the birfield out to its correct position I couldn't fit the hub.

Hope this helps

The question I have is: What does every other 80 series in the world with manual hubs use? Are the aisin hub bodies longer on the newer 80s that have the longer birfs? Or do they all use the short birfs? I thought these were not available anymore, thus the new drive plates.

I am thinking about spacing out the hub body with a 1/4" (7mm) spacer, but the dowel pins are right at the end of the hub body. I tried heating the wheel hub to get them out , but they are in there and did not budge. Any ideas?

I think somebody said something about machining the inside of the turn dial to clearance the longer portion of the birf. Any news on that?

Anybody have any different ideas to run lockout hubs on an 80 with longs?

thanks

Easy .. the 80 on the rest of the world that are part time with hubs, have no ABS, it means have a shorter birf without the ABS ring .. I thught the easy way to get it workin on a part time 80 it's machining the end of the birf ..

[trd55]

That makes sense. Thanks

I guess I need to ask Bobby about his warranty for those of us that live here in the states and might want a warranty. I do prefer to stay with the Aisin hub though.

Thanks

Me too and actually I have 'em in both of my 80 series ..

[therealratfink]

seems like you could just buy 91-92 longs...no? I had no trouble at all.

[trd55]

I thought they did not have the short size available. When did you buy?

edit: After more searching, the Longs are only the later, longer style type. I want to use the Aisin hubs (which most do not work because they are too short, but the old '75-'80 long body Aisin should work) The long body Aisins are uber rare and probably very expensive if you can find someone to sell them. I have a call into Aisin USA to see if any other vehicle lines share the long body hub like the old cruisers did.

[therealratfink]

I went through 5-10 salvage yards until I found hubs from an 85 pickup.

[trd55]

Fink,

Could you post up the measurement of the actual hub body minus the cap please?

After swapping email with a gentleman from Aisin yesterday, he said that they have two sizes of hub bodies that were produced. See below.

I found the CAD Files for our Free Wheel Hubs (FWH) and did some research.

There are basically only 2 different heights for the FWH that AISIN manufactures for the Toyota Line up.

The difference is only by 4mm.

The 62.5mm height hubs are the following part numbers for the RN series:

FHT-005 43530-35012

FHT-006 43530-35020

The rest of the Toyota Hubs that we offer were 58.5mm.

If the '85 hubs that you have are the longer ones and they work with out any modifications we could be on to something...

[therealratfink]

So you want a measuremnt of the spacer section of the hub between the spendle and the hub face? I just thought the 91-92 80s didn't need longer hubs.

[mwdubs]

sounds like a interresting job

[trd55]

After further examination, I have figured that the longer birfs and longfields can be used with free wheel hubs if you get a second grove machined further down the shaft so that it would align with the original shorter birf.

I have had all my componnets apart the past few weeks and have figured that the reason the lockout cap does not fit is because the tapered portion that holds the locking gear hits the circlip on the end of the birf.

If this circlip is at the back next to the gear the birf slides through, then it is fine. I did not have any rubbing on the end of the longer birf with any portion of the lock out cap. The birf actually fits inside the recessed portion fo the cap a good ways.

Now I just need to take it all apart and take my longs to a machine shop to groov another notch for the circlip.

My limited researched has never found a birf fail at the shaft, so I am taking this into my own hands, but I do not feel that the added clip groove will be any different than the other one located further out. I do believe in the Aisin hubs more that having a drive plate or a warn hub.

Again. If you do find the ultra rare long body Aisin hubs, this will work with the longer birfs without any modifications.

Good luck. I will report back with my findings and hopefully pics next week after I get it apart, machined and reinstalled.

Darius .. can you take plenty of pics of your mod .. ?

and without the c-clip .. !
