When I first got the H-10, I stupidly removed the old spindle gear (the short one) without the right tools, so I could put on the extended gear for the 5c collet closer attachment. I used only a screwdriver and hammer. I did not have a puller. Damage resulted to the spindle and key. See pictures.

I want to fix that (stone it down?) and properly install the extended spindle gear for the closer.

Those of you who have the H-10, PLEASE tell me how I do this PROPERLY. I have PVC and threaded rod to make a press. Please tell me HOW to do that, and how to line it up and whether the way it is shown in the picture is the correct orientation.

I need to PUSH MYSELF to fix this to begin getting the restoration done.

THANKS!!!

I have done the same thing in the past....
Try and remove a part without the correct tools and have always damaged something.
Now i always buy the right tools for the job, gets expensive but at least you know it is done correctly.

I would stone or scrape it down carefully.
If you are good with a dremel and have some softish rubber wheels they also work wonders.
That is what i use to correct small issues like you have pictured.
Scraping also works really well!
Lock the back gear so that the spindle does not move and carefully scrape away the affected areas.
Polish with a soft rubber point in a dremel and you will be back in business!!!

Let us know hoe you make out!

Replace the key, or stone it and leave it?

How do I press the gear on properly?

I would lightly stone the top of the key.
You will not get the whole ding out of it and it is not vital too either.

Just stone the top and the sides so that the burs are removed.

If you can remove and replace that would be ideal otherwise just remove the burs so that it fits smoothly into the keyway.

The new shaft and gear should slide smoothly onto the existing shaft.
If not a little go over with 0000 steel wool should help.
Also a little lube never hurts.

If you find you have to resort to Mr. Hammer i would remove it again and check for burs or any raised areas.
Ensure it goes on 100% straight and parallel otherwise you will run into problems.

I use a wooden block and a hard rubber mallet to tap stuff like that into place.
You should not need a lot of force.

How do I press the gear on properly? Tap with a plastic mallet, build a press from PVC and threaded rod?

IMHO clean up the nicks (edges), replace the key, check the bore of the gear, clean it as needed, a super light lube on the male, set it up to push together making sure all is squared up and like said by the others make sure there are NO burs...It should slide on with little force...But I own a Logan so I can only guess from age and experience...A rubber or plastic mallet or a hammer and piece of wood....Jack

As the key does not appear to be damaged on the flanks, only just a slight screwdriver divot on the top side, file or stone it down to make sure there are no high spots.

Next file or stone down any high spots on the spindle of the lathe, do not worry about a few small hollows, all you need to do is make sure there aren't any high spots.

As for the gear, either use a dead blow mallet or make up a puller with a couple of heavy washers, a length of all thread and few nuts and by tightening the nuts you will draw the gear onto the shaft, watch your alignement on the key so that as it pulls on, it will line up.

Now is there a retainer for that gear to hold it on, or is it just a press fit? It may even be a tight slip fit in which case it should not need much force to seat it.

all thumbs
when there's a nick in a car crankshaft
you remove anything sticking UP.
i have a 3 sided scraper for
cutting off 'shaving'?
then in the gouge whatever surface area you lose
on a crank journal you still got plenty left.
you just don't want anything sticking UP.
getting keys out is always a pain.
use 3 in 1 oil and shock it with small hammer.
use a pair of dykes and put an allen wrench under it
or something hard for leverage and pry it up.

Have A Nice Day!
 
Ok, I'm going to take a shot at smoothing it out...then I will try to get the gear on.

Wish me luck guys! :thumbzup:

Ok guys, I used a fine india stone I had here for clock work. Then polished with some scotchbrite, first mild abrasive then white non abrasive, you can compare these to the originals:

Here is the extended spindle gear temporarily in place. The key has a huge dent, and I would like to get a new one. It doesn't show in the photo, but someone scribed two parallel lines from the outside of the key to the end of the spindle, providing a guide to line things up.

Looks like once I get a new key, I can tap the new gear in place. :biggrin:
