ring gear

[healeyboz]

Ordered a new ring gear for the 1275. Does the machine shop have to grind and weld the new one on?

 

[jlaird]

No no, no grinding or welding. It is heat shrunk on like all ring gears, cheep job. Let the machine shop to the job.

The old one will be cut off.

Ring in heater, flywheel in Ice box flops on with maybe a tap or two.

I'm assuming you're talking about the flywheel ring gear? If so, they're a shrink fit on the flywheel. No grinding or welding required.

Thanks Jack,

I will take it in. The machine shop that is close to home are kind of, humm, (pick and ajective). I wish I could find one like the one we used in high school. Dad had them as students and in turn they were great. They would figure out anything that we needed done. THese new guys do a lot of work for the race teams here in Indy and don't seem to have time for the "little" guys.

P.S. They have messed up a two motors that I have taken to them!!! I have to inspect everything that goes through them and recheck. Pretty fun to take things back after you dind a problem.

This is not much of a job. Just make sure that they have it on the correct direction. Starter engages from the rear remember and so the rounded ends of the ring gear need to face that way.

Now while it is in there you could have it lightened and balanced............

 

[healeyboz]

I was told that it couldn't be lightend and balanced. This isn't true?

Then for crying out loud, why are you still going there? There are tons of good shops in your area to choose from.
From the sound of it, and seeing what they did to your head, I wouldn't let them sharpen a lawnmower blade!

True Jeff.
Everyone else that I know of have had good experiences with them. And have had to take things back to them that have been wrong. There is another shop a little further away. Looks like I will have to give them a chance.

P.S. they didn't build the head.

It can be lightened, but not below about 12 lbs. The back gets shaved out and a champered (sp) is placed on the outside face between the disc surface and the ring gear.

Do not let any shop that you are uncomfortable with do this service. Bring it to someone with LBC machine work experience!

how to change a ring gear

here ya go....have fun /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

 

[healeyboz]

Thanks Zimmy.

With the weather as cold as it is it worked perfectly!! I set the flywheel outside in a trash bag for a few hours and put the ring gear in the oven on Broil. Laid the flywheel flat in the garage and the ring gear went on like a charm. I just used a hammer to line it up at tapped around. NO pressure what so ever. It is cool now and looks perfect!!

Thanks again.

 

[jlaird]

Boz,
Congrats! It's always a good feeling when things go well.
Somewhat makes up for the times when they don't. (Not that I would know about that LOL!)

 

[healeyboz]

Yeah, I love how the tasks on this car seem to happen at least 2 or 10 times!!! LOL

Learned this as a 19-year-old in western PA: Me Ol' Fella laughed at me whining about having to take the new ring gear and old flywheel to a machine shop... proceeded to cut the old gear off and toss the 'wheel out onna concrete back porch (t'was dead o' winter--temps inna teens). He then suggested I say nothing to Mum about use of her oven for the proceedure to follow... /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

 

[healeyboz]

Yeah, I had to keep the fact that I had car parts in the oven a secret as well. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif
