I built our housing, i didnt set the snouts in the tubes right, and instead of a 60" centered, i got a 61" centered.

Anyway all is fine there, i can still use it. Now i am trying to measure the axles to get the proper ones.

I got a long 37" axle to use to measure for a new one. My question is, whats the procedure for measuring axles?

I got 28 splines and a mini spool if that helps.

How far do you put the axle in when you measure it? I installed it, and pushed it all the way in till it wouldnt go anymore, then measure 3 1/2" sticking out. So that should leave me with 33 1/2" axle. How much slop should i account for, 1/2" so i should order a 33" axle?

D&M's catalog says a 61" centered should use a 33" and 29" so i'm abit confused, not to hard to do LOL !!

Thanks, Krom.

Install a gear in the housing, put a couple nuts on it, then take a good sturdy tape and measure each side out to the very edge of the drive hub and you 'll have exact measurements, just go right off the pin in the mini spool. Get the drift Kromolous??? It's easy and probably the best way to do it.

Ok, i got it thanks Xtreme12x.

I've just never done it before, my brother usually deals with the floater / rear end parts and i was unsure if you have to account for any play or do you want them tight (between the mini spool to drive flange cover).

I'll retake my measurements and hopefully get the right ones now.

Thanks again, Krom.

standard centered 60" is 32.5" right and 28.25" left just add an half to each side if you have a mini spool with a pin in the center if a it's a full spool you can use a longer axle you pick the side

That works if you have a mini spool as tehre is a pin in the middle to stop the tape or whatever you are measuring with. If you have a full spoool it is open all the way through and you need to make sure you have good spline engagement in the center, in other words you dont want one axle or the other in or out too far.

With our full spools we set stop bolts on the insede end of the axles and adjust them so that when one cap is in place and you push the axles tight to theat cap there is 1/8" of less between the other axle and the cap surface. That way the axle is nt trying to slide back and forth and wear on the splines.

Kromolous said that he was running a mini spool... and on any car that you are unsure on axle lengths the best thing you can do is slap in a borrowed gear with a mini spool and measure for new axles... then you just add your bolts to the end of the axles to get your spacing for a full spool. They also make nifty adjusters for the job but the regular old fine threaded bolt does the job on solid axles.
