30mm Swingarm Removal Tool - New Design!

[cccpastorjack]

A while back I posted a picture of a new design prototype tool to be used in the removal/installation of the 30mm Swingarm Pivots on a K1200LT for the Clutch Slave Weep Hole procedure. I showed my "cutout socket" version to a guy at church and he came back with a better design that lets you access the allen head through the CENTER of the socket instead of the SIDE cutout.

I went back to him with a few of the suggestions made by DShealey and others on this site and below is his final product. It looks fabulous and is VERY well made....very high quality tool. Here are the changes:

1. He now includes a typical "L" shaped allen wrench, but it is handmade from 12mm stock, with an extra deep head and extra long handle for increased stability instead of a "T" handle. (thanks DShealy for the idea).

2. The end of the socket that fits over the 30mm nut has been turned to a flat (90 deg) angle to give increased "bite" on the nut.

3. A broached brass bushing has been added where the allen wrench goes through the socket ensuring better stability during tightening. (really nice ;) )

He says that he can make as many as needed and offered them to members of this site for $97.50 + shipping. For this price, let him know that you are a member of BMWLT.

I stand to make NOTHING from any sales...and have no interest in any gain on his part, but just thought I would post this as a service to you guys since people continue to request the 30mm socket to perform the Slave Weep Hole Procedure, etc. This is another alternative for all of us.

If you are interested you may contact him directly at edgroup07@yahoo.com for more information.

Hope this helps out for some who still need this tool.

Very nice looking tool! As a newbie, what will I need this for, and, how much does BMW charge for their version?

This tool is used to re-torque the swing arm pivots after removal for a variety of prodecures. Do a search for "Clutch Slave Weep Hole" and you will see plenty.

BMW's tool is much higher in cost. Some have used a cut out socket, but it seems hard to get hold of. Just another option.

A very nice looking tool mfg. The addition of the bushng is a nice touch, just don't store it with the bushing in it...dissimilar metals and all. Don't let BMW see this tool or they may want to buy the design from him.

How much will you have to change the Torque settings when using this tool?
Or since the torque is so high to start with does it not matter.

Most on this site say that if the torque wrench is kept at a 90 deg angle, there should be no or very little change in torque settings. Don had an engineer do the math and he said it should reduce to 108 ft lbs to equalize the added 1.375" offset. It comes with this information on an instruction sheet.

I was always told that as long you stayed 90* off the extension tq. was close enough.

Twin Cam/Evo rocker boxes come to mind, as I have done it a bunch of times.

Someone can set us strait if not correct :confused:

EDIT: It is a very nice looking tool. If I did not have one, I would be on that in a heart beat.

Damn, beat to the post and never knew it, fast, and then the dead around here :D

The 90 degree approach is best, only a relatively small error that way. The same method is used with Crow's Foot wrenches used to torque fasteners.

David is correct...and especially at these high torque values it is relatively insignificant. The real challenge in doing this procedure is to tighten the outer nut that much while being able to hold the inner allen head still at a much lower torque setting. The problem is solved with this tool.

Several folks have PM'd me wanting to order them, but I do not make, have or sell them. You can order them directly fom Don at edgroup07@yahoo.com and he will send you all the information you need. He's a really great guy and a genius in a machine shop.

Very nice, having helped to do this once before I can agree that this will make it much easier, thanks Jack getting your friend involved!

[rattler50]

I made my tool for $15. It's not as pretty but I'm a southern engineer............. :D

[cccpastorjack]

I understand. The guy who makes this one is a tool and die maker/machinist/inventor of strong German descent. Just can't seem to do anything halfway! Beautiful tool!

[cccpastorjack]

Hey...I've even got him working on a couple more tools now. I'll be sure and post them when he gets them to me. ;)
