Lightweight 46mm socket for rear axle.

[champ87]

In the thread for the Motomfg Bike Lift group buy DEcosse mentioned a lightweight socket from the same supplier. I bought one of these 2 years ago and posted details in the Sprint forum. I'm posting details here because there may be one or two who want this useful addition to the toolkit that haven't read through the group buy thread.

When I first got my Sprint I bought a 46mm socket from Northern Tool. Unfortunately it was only available in ¾” drive so it’s a weighty item. Not a problem in the workshop but definitely noticeable when added to the toolkit for a long road trip when I also to carry an adapter, figuring that in a roadside emergency I could find someone with a ½” breaker bar. I had the socket machined down to reduce size/weight but the slimmed-down version is still a bulky piece. I was so glad when I found these lightweight sockets that Motomfg were selling on eBay.

The hard anodized billet aluminum socket is smaller and weighs only 156g (5.5 oz) compared to 470g (16.6 oz) for the steel socket without the adapter. That might not seem much when you consider the total weight of a Sprint loaded for a two week road trip but it slips into the tool kit easier and is less likely to rattle around. Definitely a useful addition to the tool kit that hopefully I’ll never need to use outside the workshop.

^^^ that is a really good idea to have reversible socket 2 sizes in one for the Ducs
Both sides same size on Triumph though

I bought one of these. Not lightweight, but easily carried on the bike, and fits 1/2" breaker bar. Made for VW axle, available on eBay or from various vintage VW tool sites. EMPI is (one of) the manufacturer. Search for 46mm vw axle and you'll easily locate. Works fine.

Now what I want is billet aluminum, shallow 46mm 6point on one side, shallow oil filter socket on the other in 3/8 drive..

I'll take one as well. Get to work, chop, chop.

Since you said it works fine, did you forget to include a caveat that an extension (crows foot) torque formula calculation is needed? Otherwise one would be over-torquing the nut.

Didn't forget, just didn't think it was relevant since the question was about carrying the tool on the bike. No calculation needed for using a crows foot with a torque wrench if you turn the crows foot 90 degrees to the handle of the wrench.

Maybe....maybe not. Recommended standard practice is under 2.0 inch at 90 degrees, use the factory torque. Anything longer than 2.0 inches at 90 degrees requires calculation to be done correctly. Remember, torque is a vector product.

Don't know if this is the case, but the 90 degree extension torque rule is often confused with a 90 degree offset. The extension does not require a calculation, but an offset may. The two terms are not one and the same.

Looking at the pic, it seems that the Empi crowfoot dimension would be more than 51 Mm, but admittedly by not very much.

And maybe it is just me, but it seems that not over-torquing that nut is relevant, wherever you may be.

regardless its heavy, and tough. they don't call it a slap socket for nothing. I have one for my FV. Put it on the axle nut, then bash it 2-3 times with my mini-sledge, done.
