Need help on how to open bottom bracket

I am overhauling a almost new early 80's Takara 12-speed. I took off the crankarm, and now want to disassemble the bb to clean and lube. (see picture below) #3 is the spindle, but is #2 the lockring and #1 the adjusting cup? Do I need a special tool like a Park Pin Spanner SPA-1 or does someone have a homegrown solution? Thanks for any advice!

Go to http://www.parktool.com/tool_indexes...aring.shtml#bb
You need a lock ring spanner and a pin spanner.

Yes, agreed. Don't homebrew these things.

You can remove the steel lockring quite easily with a drift from the steel adjustable cup. People, including many shops, did it that way for decades without any lasting damage. The adjustable cup can also be removed without any special tooling. It is somewhat more problematic to properly adjust the cup without a pin tool upon reinstallation. A more appropriate question is: Why would you want to do it without the right tools as they are readily available and cheap. I would suggest that you build up a good relationship with your local bike shop and have them show you how to use the tools you buy from them or have them do the work for you.

I appreciate the advice about getting the right tools to do the job, but sometimes it good to know how to do something on the fly, if you need to. I found the correct tools on the Park website (see below) and will be getting them shortly. As far as the LBS, they are friendly and seem to do good work, but I'm starting to get the feeling they always want to make a repair or maintenance job more complicated than it needs to be. For example, I have been cleaning and lubing my rear bearings since the 70's, and never found it necessary to remove the freewheel. But when I was at the LBS, the mechanic seems to think you *had* to remove the wheelfree to relube the bearings. I know it might make it easier, but it not necessary.

As the OP said, there are other ways to do it. I 've got the tools,and have also used alot of Bubba tricks without buggering anything. The trick is to understand what you are dealing with. Putting it back together and adjusted correctly is a bit sketchier without the right tools,but dooable.

follow these 2 steps:
#1 get a big hammer and chisel and bang the **** out of it, make sure you take huge swipes at it with the hammer.

#2 disregaurd every thing in step #1 and follow Dave Moultons advice, 'cause he's 'da man!

Don't forget ear plugs. After swinging that hammer like it was meant, not like it's a purse .... makes quite the noise.

I've done it with an old wood handled screwdriver and a hammer (to remove the lockring). I just stick the flat blad of the screwdriver in one of the notches and tap it lightly until it's loose enough to do by hand. The reverse can be used to retighten the lockring. Don't hit too hard or you'll probably take a chunk of paint off the BB shell.

It worked fine for me but was kind of annoying and slow.
