Wheres my Birfields

[cali-cruiser]

am I just retarded or does any one make Birfields for 76 and before. All the companys start at 76 and I've got a 75. I'm wondering if 75s are strong enough so no one makes them or I just don't wheel very hard. Any info apreciated


thanks

I had weaker '75 coarse spline birfields and already swapped them out for later mini-truck/fj60 longfields, I beleive the reason you don't see aftermarket for '75 and older birfields because there is small market for them, people can easily swap these weaker birfield for the stronger mini-truck/fj60 birfields.

Still have a '75 birfield on my desk in the office.

I have 4 coarse birfs sitting in my dad's shop in Turlock if you are looking for some. PM me if interested. I believe peesalot just sent some to Bobby Long to get treated also. They are just smaller and weaker. If you switch to a disk front end it is easy to do the mini swap and get the stronger birfs and better hubs in the process.

so there are companys out there that will treat them. How much will this tipically run. thanks

By the way any relation to james silvia

 

[bsilva132]

no relation. I would just call Bobby and find out how much. When I did my mini birfs it was $55/each but that was a special he was running at the time. Here is the web site:

Cali-Cruiser... Do you have a drum (E-9/75') or a disc (9/75 +) front axle?

If you have drum brake axle, don't waste your time with the birfs, do a disc brake conversion, or swap a disc brake axle.

If you have the disc brake axle, the birfs are the same as the 76'

Hope that helps...

I've got the Man-a-Fre disc kit on my 5/75 axle. So what do you think would be the best option?

hey cali you can get a set of stock aisins hubs from a mini or later cruiser and then you'll be ready for fine spline birfs. the only difference i know about is that running the cruiser (MAF) parts the mini style birf wont be long enough to put the circlip on, but there is a threaded hole in the birf and you can use a bolt/washer in place. the only way i know of to get around this is to swap to a mini/later cruiser disc set-up.

I don't think that will work as his drum spindles and hubs are too short, LOL. By the time he's got the spindles and birfs out, he might as well as put on minitruck knuckle housings and the rest.

Agree, the only option of using the minitruck or later 40 birfs (and any of the aftermarket birfs) is to do a complete conversion.

MAF Disc Conversion.... Ho do they sleep at night after selling that??? Knowing that a true (FINE SPLINE) conversion can be done for the same price (or cheaper)... WTF?

Anyways... your stuck... Longfield "might" heat treat them for you, if not there are other options.... Best one IMHO is to can it and go OEM disc (be it Minitruck or Cruiser)

I got sucked into the MAF conversion. It has performed flawlessly since installed. I'm very happy with it.

I do see the problem with the early birfs though. I may send the extra pair I have to Bobby for treating one day... Maybe. I might just stockpile a bunch of them and be the fastest birf swapper on the planet

I may change my tune completely once I get the front locker installed... We'll see. I intend to use the 2-lo mod on my xfer case to save birfs too.

I just got back from Moab ran 6 difficult trails including LPG with my cruiser on 35 SSRs and a front locker and didn't break one of my coarse spline birfs! I could freaking believe it. I was hammering the crap out of my truck this weekend too! Don't let this miracle sway you, the coarse spline birfs suck! I have broken many of them just turning in 4 wheel drive at idle. I just drive in 2 wheel drive till i actually need the front; I still have the vacuum shifter which is great if you ask me. As long as your hubs are locked you can hit the switch while moving and it will shift in and out of 4 wheel. Poor mans selectable locker

I have a set of longs and I am just waiting to get my FJ 60 axles ready to go before I actually get to use them.

I'm surprised at how long mine have lasted too. I 've grenaded a hub and twisted a drivline and stil no birfield break.

Now it will happen tomorrow when i'm in two wheel drive and running on the highway.

 

[peesalot]

yup , sent birf's to bobby , have not heard back but soon . PM me if you are interested cali ---- I am also practicing to be the fastest birf swaper in the west. And cali , as a tip , martac the inners while it is apart so you can change birfs really fast.

I've got my time down to about 15 mins. Cool thing about drums is that you can get to the 8 spindle bolts right after you take the drum off. So you just have to take the wheel off, undo those spindle bolts throw that broken crap out and toss in a new one.

That's a fast draw!!! Just wonder how many birfields you have to blow to get you there?

You got me thinking... we should have a "Birf" swap contest at a TLCA event (for sure at the 05' Cruiser Outfitters Pig Run)...

My UROC partner and I swapped one in nearly 10 minutes... And last season, Tracy Evans (Modified Class) and I swapped a entire front 3rd in ~30 minutes... Didn't take brake down time on any swaps...

Feels like a Nascar pit crew when your going so fast...
