Where is the filler plug for the rear axle found on a Spridget and what is the lube capacity?
 
2.1 pints of GL4 is what I have written down. Filler plug is on the rear, somewhat near the top.
 
Agreed, 2.1 US pints. If you have an early diff there is also a plug on the side of the housing, on the right I believe. Attached is a pic of the rear plug.

That pic rings a bell -- haven't been under the Tunebug in a while. That's what I've got on mine.
 
The next thing is to have the proper tool to to take the plugs out, what I did was buy a really cheap 1/2" drive extention and then with a little careful grinding made it the perfect fit for the plugs, then you have the right tool for life that will fit on your 1/2" drive rachet. Hope this helps.
 
My 3/8 ratchet seems to work just fine??????? Always has.

Yep - second that!
 
Chris--

It was there as on the drawing big as life. My question was prompted because the present 4.5 diff on the Elva has a filler/level plug on the front carrier whereas there is none on either the 3.9 and 4.2 sets that I just purchased.

Thanks for the good information.
 
Trust those Brits to build something that requires a special tool to do routine maintenance...

What percentage of owners has a 3/8" square drive in his (or her) toolbox?
 
Michael, filling a diff ofr racing, since I know you race an Elva with a Spridget rear housing is a little different than a street housing, you should not fill it till it come out the check hole. If you ask a ton of long time spridget racers where it be myself or others like Randy Canfield, Harold Flescher etc, you almost always get the same answer, fill the diff with it leveled until you can take your pinky and bend it at the first joint and jsut get diff oil on your pinky, overfilling the rear diff, just seems to flood the hub area and caase axle leaks and hub seal failures on race cars. I would also recommend a set of Winners Circle double bearing hubs and Winners Circle racng axles. Also this set up does not have the great greatest hub retention devive known to man, so much car should be taken. I highly recommend cleaning the hub nut and threads on the housing with solvent, brake clean etc., and air blowing dry, then use red lock tie and torque to factory specs of 140 ft. pounds. Many of a racing with a Spridget rear housing has caused great damage by not following these instructions. I can't tell you how many hub nuts I saw with chisel marks on them, where people just hammered them on, very bad idea.
