Hunting around the forum as always, trying to pick up on new tips n stuff. I've come accross people mentioning paste for their gears for a new car. Today is the first time i'd seen anyone mentioning paste for gearing.

Ok, so what is it? What kind of paste? What does it do? Where do i get it? What kind of gears would you put it on? etc etc

Cheers folks!

Paste eh. I use toothpaste on my gears. I use it when the mesh is rough or noisy or both. What I do is remove any grease off the gears first. Then put some toothpaste on the gears. I then sit the car up on a 9volt battery for 15mins or so & leave it to work its magic. Some cars need more, some need less. If you sit there & listen to it you really notice a difference to the sound of the gears as it smooths out. After Im happy I clean off all the paste, very well, leave no paste behind. Then reapply the grease of your choice. I only ever use this method on plastic gears.

Anyway thats what I do, hope that helps. I dont know weather Im right or wrong in what I do but it works for me.

Works well on brass gears as well.

The reason you use paste is to speed up the wearing in process and to take of the high spots etc on the face of the gear teeth and polishes them up to help get a smoother mesh between the pinion and the crown wheel/ spur gear.
Your best using the cheaper chalky toothpaste rather than the more modern green stripey stuff. I've got an old tube of Ipana floating around the shed somewhere just for this purpose.
you could use valve lapping paste too, though I have never used that so can't say how it would go, maybe too abrasive ?? .

Smoker's toothpaste has previously been recommended. Jiff seemed to work ok 'though I've only used it in a plastic on plastic gear mesh.

mmmmmm paaasste...

It shouldnt really be necessary with todays tight tolerance technology but unfortunately there are times when it seems worthwhile...

I usually reach for jif but can proudly gloat that I haven't used paste for some time.

Remember, if it doesn't feel right,sound right or look right....it's not right.

Car cut and polish works very well. I use Chromosol (Chrome polish) but have used car cutting compound to good effect.I have found the fine valve lapping paste to be too severe and detrimental to the plastic type gears although it is good for the brass ones (Brass to Brass)

Don't let them kid you Tim, they're making fun of your misspelling.. they actually use pasta. The starch forms a film over the gears that lets them run more freely, kinda like coating things with graphite.

Then, of course, if you use a pasta with a nice red meat sauce you can pretend you ran over a 1/32nd scale cat..

Tamiya make an Excellent product called Ceramic Grease that comes in a White tube, similar to their Switch lubricant.

I have used the Product over 20 or more years and was simply THE Best stuff to get a Perfect and Silent Mesh with FAAS gears.

Works Very well on Plastic as well. After they have Worn In,..I have been using Avany Slot Oil on my gears, as it is a Nice sticky oil that does not 'Spin Off' but also does not seem to Gum Up etc.

Ah, cheers guys.

I'd just never heard of paste being used on cars, then came across it twice in one day so i was quite curious.

Now to go cook up some pasta and find a small cat...
