Font Axle Rebuild - Final Step - Axle Snap Ring Space Issue (1 Viewer)

[pb4ugo]

I took the dial off my Warn lockout and measured the in and out play with the C clip installed on the birf and came up with about .063".

The Birf has a fixed length between the base of the stub shaft at the bell to the snap ring groove. The spindle, the hub and lockout needs to fit within those parameters. In your case you need to figure out how to alter/shorten the combined length of those components so the snap ring can be installed if you use those lockouts. As i mentioned previously, folks have eliminated the gasket and glued the lockout to the hub or tried a thinner gasket.. A more aggressive idea is maybe thin the mounting flange of the lockout, or take material off the brass bushing on the backside of spindle. Or find a pair of original long body Aisin or Warn lockouts. I believe Aisin 's were only offered on FJ55'S, so they're bit rare.

Ok, what is the purpose of the movement of the birfield in/out by 1/4 inch to 1/2”? I’ve not taken apart the differential to see. With the end of birfield pulled outbound, and the C clip installed snug up against the inside of the locking hub, therefore restricting movement inbound or outbound; will this interfere with the proper function of the locking hubs?

Like the slip yoke in a driveshaft, but for steering.

Not really the same thing. The inner axles is free floating inside the diff. Driveshaft it's anchored solid at both ends with a slip joint in between. Birfield it suppose to be anchored at the end of the spindle. If a C clip wasn't suppose to be used why would it have a groove in the outer spline?

Would be interested in the zirk in the end. I know on my 68 with ball and claw versus Birfield the threaded hole is used to insert a bolt and pull the axle out to install the C clip.

Too bad Toyota didn't put the two threaded holes in the end of the brake drum until 8/80. Those are not for installation but removing the drum.

For reference here is the late seventies starting 9/75 part number for the C Clip. 90520-31001. Same part number for same date drum brakes.

90520-28038 is the earlier C clip up to 9/75.

RCV axles are riffle drilled and the zerk is to grease the birfs .

The CityRacer long body hubs fit my birfields. The issue I had was simply not pulling axel all the way out to fit c clip. I also was expecting more movement but according to this thread, the play is adequate 1/8th - 1/4” and not tight.
