I want to swap tach flywheel on a worn motor to a non tach new spare motor.

The base is to thick to get under the fly wheel. I have a wheel puller from NWSL that's thin enough to get under the fly wheel, but I had to file a grove I it so it would slide over the tab for the wires. I'll get pictures posted tomorrow. I'm sure other guys will have suggestions.

NWSL won't work. Flywheel won't fit under the frame. I even tried thinning the aluminum frame to fit and it bent the framebox and didn't budge the flywheel.
Could you post a picture of the old motor and flywheel, along with the dimensions of both the motor diameter and the flywheel diameter. The clearance between the flywheel and motor would also be needed.
Thanks.

Do it right and get the puller Frank Timko sells. This puller is great for flywheels, wheels, and gears. I use it often. This puller is recomended by Mike Reagan from Lionel Customer Service. Using a puller must be done correctly or you can cause regretable damage. When buying a puller, do not cheap out.

I have heard that flywheels and worm gears have a form of CA glue reinforcing the friction fit. It might be useful to apply some heat before attempting to pull them.
I was up at 0130 this morning (couldn't sleep) and was looking at gear/wheel pullers. The one Marty F. shows seemed like the strongest of the lot to me. I saw a number of pullers meant for slot car gears/wheels but not sure if they're strong enough.
You could also do this:

I might give this a try just for giggles.
While I made my own, the one Marty recommends will do the job. One thing I would add is a bolt with full thread all the way to the end. Most of the time the motor shaft sits proud of the flywheel. Use the full thread bolt first to push it flush with the flywheel. If you try using the necked down bolt first and it isn't perfectly centered it can slip off the end of the shaft and get bent. No doubt Frank uses common SAE hardened bolts and you should be able to find one at any hardware store.

Good thinking Pete
I have never had a problem pulling a flywheel with my puller and I have never had to put heat to any. Many pullers are designed for different jobs. I had a NWSL puller and it is only good for an axle off the locomotive. On Lionel locomotives to replace the odyssey board under the flywheel the Timko is the only one I have found that will get the job done. Fooling around with the wrong tool can cost you money in the long run.
Again, the right tool to do the job is the best idea. I do a lot of these and the Timko tool is not a lot of money.
I want to second Marty's suggestion, He told me to buy this one and I did works like he said.
Thank you Marty

Willy, it's a lot easier & cheaper to just buy a tach tape if the new motor has a flywheel. If not, unless you expect to have much need in the future, it might be cheaper to get an entire motor with flywheel. I should note that over the years I have often bought tools to do just a single job, and they've been hanging on the pegboard ever since.
Marty, I don't see any mention of it on Frank's web site.
But I will get one like Marty posted.

Whos sells tach tapes and do they have self adhesive? The one i need has a black 24 count and fits a MTH GP35 premier.
Willy,
MTH sells as sheet with a set of adhesive-backed tach tapes. You can also most likely get a sheet from most any MTH repair shop.
This sheet also comes in the PS2 (and PS3) upgrade kits.
You can also print a tach tape, I've done a number of them using gummed shipping label stock. Attached is a 1:1 scan of the MTH tach tape strip, if you print this at actual size from Adobe Acrobat, it will be the right size. Use the LABEL setting of the printer for better quality on the gummed label stock.

Ralph, I purchased the Timko took because the NWSL will not do everything the Timko will. If I remember, it was about $42.00. Yes you can get the NWSL under an MTH flywheel if the flywheel is set high enough. Not many are set that high. Ihe ID of the NWSL frame is 1.25 inches with very thin screw shafts that come with the unit. I used it on a few times and set it aside. It is a good tool for HO guys.
Ralph, if you get the Timko you will be very happy. I have seen some Lionel flywheels that are very tight. It will do the job. I was not aware of the tool until Mike Reagan told me that is what his people use.
