Myford Super 7 fiber tumbler gears

[Daniel PlaceParticipant @danielplace92871]

Would anyone know where I could find a pair of the two fiber tumbler gears for a Myford Super 7 ?

Any help would be greatly appreciated.

Thank you,

Daniel

Have a look on Ebay. Just type in Myford Gears and select from what is available. One seller "marypoppinbag" did sell them as a set for about £30 but that dealer is no longer advertising others may provide the same gears.

Ray,

Thank you.

I appreciate it. I had been searching all evening and was beginning to think they were totally obsolete.

I was searching Myford part and Myford gears and plenty of other gears but not the Tufnol fuse tumblers gears.

Then I finally by chance searched Myford Tumbler Gears and I have a used set coming.

There were even new ones still in the package but the seller says he doesn't ship to the U.S.

Still not positive how you get them off the arm. It appears the posts they are on must just press in.

It looks like a shaft in a sleeve kinda from the backside. Don't want to mess it up banging them out if there is a proper way.

Anyone know the best way to swap the tumbler gears on their shafts?

Thanks again,

Daniel

Myford.co.uk (ie NEW Myford) sell them at £30.38 + vat the pair and of course they are new.

To fit, take the lever of the headstock and push out the "gear pins" from behind, then reinstall. The push fit is not that hard to do. NO banging required.

Kwil,

Thank you sir. Lol NO banging !!

 

Used the vice and pressed them boogers right out.

 

At first I wasn't sure if just the center pushed out or the whole peg. I used a small 3/16 tool first and the center pushed in but the peg nor the outer head on the peg wasn't moving.

I then tried the whole piece and it pushed it right out.

My only question now is why do they have a pin in the peg. I actually pushed one of those center pins in about 1/8". Will that center piece being pushed in make any difference.

I think I see now that it is capping off the pocket for the grease. The grease hole is still clear in side of shaft so I didn't push it in beyond that hole so hoping it will be fine.

 

Thanks again,

Daniel

NOT grease, always oil, nothing on a MYford uses grease for lubrication. Common mistake because some look like grease nipples. What you pressed inside was such an oil nipple.

When you replave the arm to the headstock, tighten the "Tumbler Reverse Locating Screw" just enough to hold the assembly close to the headstock, any overtightening will make it too stiff to use and also can force the "Tumbler Reverse Stud" out of the Lever itself.

Hi Daniel

Go to Myfords web site and look at the parts for the ML and order from them i have just replaced mine on a Super7.

I was pushing the pins out, from the backside. What I pushed in was the plug capping off the hole they drilled in center of gear post. There is a 3/16" plug in the center. It went in 1/8" but not past the cross drilled hole so it can still get oil from the fitting. The oiler fittings are on the front side face of the gears. I didn't punch those in.

Appears it will be fine. Had I pushed the center plug any further it would have blocked the cross drilled hole feeding the gears bore.

 

Thanks for every ones help. I do appreciate it greatly.

 

I will remember to only tighten the pin holding the assembly in to just take the free play out.

You certainly needed new gears!!

[Daniel PlaceParticipant @danielplace92871]

You are not kidding. Lol.

 

I still don't really know what locked it up.

 

Was threading and carriage was engaged but not bound up in any way.

 

I disengaged the clutch and reversed the travel and when I dropped the clutch back in. BAM!!! Opened the door and saw it tore 1/4 of the teeth off both tumbler gears.
