How to mechanic headset bearing service continued.
Next, grease up the upper cups and insert the bearings correctly using the pic you took for reference. Connect the cups and screw the cup onto the threaded tube. Put the keyed washer on and the lock ring also. Hand tighten.

Take the expansion bolt out of your stem and clean it. Clean the stem also. Put some grease on the threads of the expansion bolt and reinstall.



Cinelli stem, sweet! Is that OEM?

Reinsert the stem/handlebar assembly into the headset/tube. Hand tighten the top bearing cup until it snugs up and you feel resistance. Check that the fork is not loose, but moves freely. Similar to the BB bearings you want the magic point with some bearing load. Not loose, but moving freely. When you find it, tighten the lock ring down while holding the upper cup steady. This is tricky because the tool for the cup has to be thin. I am using a big pair of vice grip needle nose pliers with thin fingers.

After getting the lock ring tightened, align/adjust your bars and tighten your expansion bolt. You are done!



We still have to do the hub bearing service and some other minor services. I'll do the hub bearings in a day or two.
Questions or comments? As usual, get them posted.

Nice write up Pat!

I would also add that you cover the stem with grease where it will be inside the fork steer tube. this will help prevent the dreaded "Stuck Stem" syndrome.

Good job Seypat, where were you 30 years ago?
BTW, cenelli stem is not OEM to the '86 Ironman, the Nitto stem is.

Just keeping the flame burning. Giving people something to do during the lockdown, and the info to do it. Heck, if I can do it anyone can.
Cinelli stem, Nitto bars. Stock looking bike. Doubtful the PO changed it. Someone did in the past. My gain.

Was this question answered? The BB spindle lengths for the 2 models according to Velobase are:
BB-6207 600 series. 116mm
BB-1050 105 series. 113mm
You will need the Shimano cartridge BB that replaces those.

Well, I had to service the hubs on the Miyata, so I decided to do the ones on the project loaner IM. Good news and bad news. The bad news first. One of the hub cones is pitted. It will need to be replaced as well as the bearings.


The good news a cone is pitted. The cones and bearings need to be replaced. We get to go through the process of finding the replacement parts and learn from it. When I get the parts in I will finish and post the procedure.

Can I swap my 6-speed MF 6208 (13-21) for a 7 speed freewheel? Maybe something with a bit more low end?

Would the width be the same, or close? Will my 600 shifters have enough clicks? (Front is a 53/42 Biopace.)

You can get a 7 speed freewheel, but wait until someone answers your question about indexed shifters. All I run are friction shifters. I don't know about the indexed mode. Let me summon one of the experts. rccardr
Hopefully, I did that correctly.

If you use a 7 speed freewheel you'll have to use the friction mode as your 6 speed will Not click 7 speed.
Also if you use a vintage shimano 7 speed freewheel you'll have no problems, however, if you use a new shimano 7 speed freewheel with the rivets on the back of the Low sprocket you will likely need a spacer in order for the small sprocket to clear the frame.
Lastly if you decide to go 7 speed SiS click shifting, you can go 105, 600, or Dura Ace 7 speed shifters and it will work just fine with that 105 rear derailleur.

Well I rode my '88 Carbon Ironman today but Only 18 miles. Last week I rode my Miami Vice 17 fun filled miles. Maybe my next ride I'll finally make 20 miles.
The ride was good even with the narrow width 20 hard as rock tires. I think the sexy flexy forks and carbon frame softened the Ride to the point where it was like riding steel. I stated my MV has a 7 speed 13-28 freewheel but it's actually a 13-26. Now, the '88 Carbon Ironman Does have a 12-28 8 speed cassette. I think I prefer the 26 for my type of riding.
Although I enjoyed the ride today it was a little cool with temp 70 and a bit cloudy. Wouldn't you know it, i was 5 miles from home when the sun came out and I felt pretty good as my ride ended.

'88 Carbon (Midnight Rider) Ironman. OEM HS, Stem, aero seatpost, Brakeset, Saddle. Dura Ace Crankset, FD, RD. Ultegra Hubs. Scott DH aerobars. Gripshift 8 speed. It's a 8 speed because it's a 1988.

Good to see The Carbonman again. Forgot how good it looks. Looks like Spring has arrived in Central Texas.
Was able to get Old Ironbutt out for 36 enjoyable miles today.
Ironbutt gives a wave and howdy to Carbonman ...

Not much Ironman content but wanted to share


Retirement day gifts
My retirement party at Lockheed was canceled due to the virus but I was told to come in to pick up my stuff turn in my badges and process out. The powers to be said NO PARTY! When I got there everyone gathered up in a socially acceptable group to say good bye. They had some things they had gone together and bought for me. I mentioned a while back that the stores were sold out of Spam due to the hoarding. Well they took care of that.

Ironman content...I'm going to wear that Spam jersey when I ride my Ironman tomorrow. We aren't allowed to take pictures in the plant so I spread my goodies out on my hood and took one at home.

You commuted between Bowie and Lockheed? Yikes. That wasn't bad up until about 10-15 years ago when 287 turned into a giant parking lot. Remember when you could drive 287 and see maybe one car every 15 minutes? Now it's 15 cars in a space for 5.

Enjoy your retirement. Bet you won't miss that commute.

Yep I had over 20 years in and often worked 6 and sometimes 7 days a week. 140 mile round trip from my house. I worked on the F-16 F-22 & F-35. It was a good job but now its time to do some things with my family. All those trips and I was in one wreck. It wasn't serious and no one was hurt.

Love the airplane model. Nice! Also like the 56 Chevy in the background

Congrats on the retirement.
