1988 R100RT Winter Teardown

Hello fellow inmates,

Well, I've gone and done it. I've ridden this thing since 1995 and never quite gone this far. Motor/Trans is staying in-I'm just trying to clean it up and get some electrical gremlins out. Haha. Omega, anyone?

Wish me luck!

Someone here said, "I spend 40% of my time taking it apart and the other 75% figuring out how to put it back together".

This is where I'm at:

Remove Bits.
Buy cleaner.
Surf Web.
Read more forums.
Procrastinate. ( Heck, I have all winter!)

So, now I have my first question for you good folks....

Does anyone /have/know who has/ an Alternator Puller and lives around 50-100KM near Guelph Ontario? Toronto BMW wants $25 for it and the guy in Minnesota wont take paypal right now. I'd rather not wait 6 weeks to get a tool I need to use once.

If anyone knows, I'd love to hear from you!

Oh, and thanks for checking, You won't learn anything on this post, but you might possibly be entertained.

Stew

To remove the rotor, take a 5 mm allankey and grind off a length of 50 mm.

Remove the bolt holding the rotor and insert the cut-off piece of the allan key.
Put the bolt back in and fasten, the rotor should pop right of.

If not, some tension on the bolt and a smack with a hammer will do.

Paul.

HA! It's a sickness, isn't it ?
I'm saving the engine and transmission until I know I can put it all back together!
Then I can take apart again with confidence!

* whines* My rotor won't stay still !

Seriously,
It's Sunday, my brain is taking a holiday. The 88 R100RT is stripped and dry...

Buuuut....

I'm trying to remove the rotor to get the timing case off-
I think I have everything I need--except a rotor that won't sit still. It just keeps rolling the pistons.

Do I need it it gear? How do I do that with no oils?

stern looks? twobyfour? Find a gear?

EduMaCate me! As God as my witness, I thought turkeys could fly!

Thanks in advance....or TDC

Do NOT, under any circumstance....use anything cut off, to fit the difference......and then use the standard BMW rotor bolt.....UNLESS IT HAPPENS TO BE HARDENED STEEL.
Otherwise, you will have a DAMAGED CAMSHAFT END PIECE....or QUILL.
Do NOT damage this.
Heed my words....or just look it up on the internet.
Get one off ebay in a week or so......What is the big deal?

Put a hex bit on a socket wrench and use a rubber mallet on the wrench end. If you strike it sharply, inertia should do the trick.

Have you tried Motobins for the rotor remover
I would put it in gear and use an air impact wrench to spin off the bolt holding the rotor on
I dont think you will be able to use the original bolt to remove it after you put the hex in it.
The original bolt screws into the cam not the rotor. you will need a larger Diameter bolt for that

I assume you have a tool to remove the rotor, or have fabricated something to put in there. I recently installed an Omega alternator and it came with a removal bolt. If you are really hard up, I'll mail mine to you. You just have to promise to send it back.

I think the real problem he's having is that the motor spins when he tries to turn the bolt. As I said, I've always been able to get the thing off by using the quasi-impact method of a wrench and a mallet. If you try to turn it slowly, definitely it will just rotate the engine.

There you go!

Thanks To All for your speedy and helpful replies.

Especially the link to the site in Kitchener.

Once I have the back tire and the brakes reinstalled, I will have had the rotor removal tool delivered.

Thank you for the kind offer of the loaner tool, as well!

I love you guys!

....and I appreciate your patience with the slower kids in the camp!
