When the Reverse lever is pushed on the Janome SD-2014 sewing machine the spring does not pull the cog along the main shaft to engage reverse. The machine is 20 years old. If it is pushed manually it works. The instruction book says the machine needs no oil. It appears that the grease has hardened on the main shaft and needs appropriate lubrication.
The grease has hardened and that is what makes it not work. You need to remove the spring and clean all the old grease off it. You can put new grease on if you want but it isn't necessary. The machine should be lubricated with a good quality sewing machine oil(not 3 in 1). You need to oil any place that moves and rubs, This includes the ends of each shaft, the needle bar and the cinnecting links that drive the needle bar. Nothing is permanently lubricated.. you'll find this machine will run much smoother and quieter with fresh lubrication.As a matter of fact, if you use the machine a lot, it should be lubricated once a year and never less thanonce every 5 years.
One more thing. If it is on the main shaft that it has hardened you can spray it with a mixture of fantastic, water and some ammonia. Free it up and give it a light shot of oil.

There is no reason to go through all the work of removing the shaft.Pull the mechanism to the right, spray the shaft with the mixture to dissolve the sticky grease that keeps it from moving freely. While it is wet,move the part back and forth a number of times. Spray it with compressed air if you have some and do it again until this part moves freely.
You really need to start with where the spring is held on with a clip, not the main shaft.

Fantastic is DEGREASING Household CLEANING COMPOUND. You can substitute 409 or any other spray on cleanser. You won't need a lot of it so don't make a whole bottle. about 1/2 ounce of ammonia, 1 ounce of 409 and 3 ounces of water in a spray bottle should do it.Spray it on, work the slide back and forth, spray it with air and repeat until it slides easily. Be sure and clean the spring assembly first as this is where the worst problem usually is.

Can I remove the main shaft easily to give it a good clean before re-lubrcating? I notice there are a number of components held in place with grub screws and the location along the smooth shaft appears critical.
I would like to replace the grease. What grade should I use?
One more thing. Can you provide more details on the cleaning mixture? I am in Australia and I don't know what fantastic is. Do you mean cloudy ammonia?
For machinery you generally strip down, wash grease off in petrol then re-lubricate. Petrol can deteriorate plastic and rubber parts. Other alternative is www.wd40.com.au/wd40/index.php.

I pulled the clip of the shaft and cleaned the dried grease. This was the main problem. I oiled the shaft and the main shaft. When I reassembled it I didn't put the lever holding the cam back in the incorrect place and it stayed in neutral. I adjusted it and it worked ok.
Unfortunately the reverse should be like an automatic but now is more like a manual. You have to depress the reverse lever and hold it down then turn the clutch before pressing the foot control. You should not need to turn the clutch on this model. Wife is happy anyway.
