I'm to the point in my mini truck disc swap that it's time to install the axles and birfs. After separating one birf from the axle shaft and thinking about what a PIA it's gonna be to reinstall the inner clip, I got to thinking that maybe I should just go with the mar-tack method and never have to mess with it again. Only problem is I have no welder...Anyone feel confident enough with the process to hook a brother up?

Thanks

I've done it, but I'm a good ways away from you. I've also used a hose clamp to compress the hog ring to get it in the splines. That worked well for me.
 
Ha! I just did this today on Stacey's 40 that I'm working on. I did it because I destroyed the inner clips when I was separating the birfs from the inners and I don't have any spare clips.

Like Mark said, you can use a hose clamp or zip tie to compress the clip to get it inside the birf.

If you still want to do the martack, I can take care of it for you.
 
Josh I destroyed my clips too. I don't think there's any way to avoid that. If you don't mind, I'd like to do it. Mainly for future repairs so I don't have to mess with that damn clip. Shoot me a text and let me know when you're available and I'll bring them by. Thanks
 
After going through the front axle on my 80-series where a PO did the Martack method, I will not go back to the Martack. I run clips in the birfs and at the locking hub. Before putting on the inner circlip, I squeeze it tight so that it's snug in the groove on the inner shaft when installed. I have never destroyed an inner circlip getting one out with the "slamming pipe" method. I've also used the "slam on an open vise" method with great success.

Georg - orangefj45 (???) - carries all the clips you need. I will never run without the clips. It's peace of mind for me, and I'm pretty sure running without caused premature wear of my birf, which required a $100 rebuild from RCV. Now, you will probably have better luck than I did because the PO didn't run a snap ring at the locking hub (dumb...).

Just my two cents.
 
Did that 80 axle have locking hubs or a part time kit? Did it see a lot of road miles? I'm just curious because most of us won't even break 500 miles a year on the front axle internals whereas a stock 80 series does thousands of miles. I could see where an 80 axle that was poorly assembled would wreck some birfs. That outer snap ring was probably your biggest cause.
 
I have it done on mine... I have blowed up the inside cage and ball bearings inside of a birf before.... Never really thought about it being the MT..... Hmmmmm
 
If done properly I don't see how MT could cause damage. Acts the same as clips. Enlighten me if I'm missing something.
 
I believe your right.... From what I remember when we did mine it was not far from where the splines started from the inside if that makes sense...

The 80 did not have hubs or a part time kit. The chassis has 256k miles on it, and I have no clue how many of those miles were with the Longfields.

Yes, totally different on a Cruiser or mini-truck that has part-time / 2WD capability. I have no doubt that the lack of outer clips played a large role in the demise of the Birfs. However, I don't see enough of a benefit to mess with the Martack. Peace of mind and faith in Toyota's design far outweighs being able to pull axles quicker or easier separation on the trail. If I break, I'll pull the shaft on the trail or pull the driveshaft and unlock the hubs.

To each their own. I'm probably the only one who's become soured by a poor experience with a improper Martack.
