It's a while since we touched on this subject.

Has anyone tried this new "performance" layshaft yet?



This was the posted that prompted my question.

Remember that hte file-test that was executed previously mentioned on this site was worthless. The shafts are only hardened on the bearing journals, not in the middle.

selective hardening, that must be an interesting process and rather expensive as well!

i done the test with miniwilliams

even on the quality standard one (used)

the file bit into non running surface but didnt touch the running surface.

i think regular layshaft bearing changes eg yearly for hp over 150 and millers cvt oil will do the trick oh and try and use a good oem one if possible.

always looking for them bigger bunches of bannanas

shocked to say the least by that :o

Question: how would you harden only a couple of areas of a component in a production enviroment?

I've seen the future and tbh its Pie

Well, I've bought one of these new ones. Should be with me tomorrow.

I'll take some photos and post them.

There is a process called induction hardening. Basically the area to be hardended is inserted into an induction coil. The coil then effectively heats just the area in the coil effectively heat treating that area only.

There are variations for tempering / softening which is often used on threads on hardened items (obviously hard threads can break up).

It all depends on the correct type of material being used of course.

In some applications flame hardening can be used although most of the steels that I know which can be flame harden aren't going to be great for be layshafts.

There are also some selective hardening processes which use an electrically based plasma too catalyse the process.

I am sure that a transmission specialist (TurboDave) could shed a lot more light on the materials used in transmissions.

Every day is a school day ...........

How fast and how expensive ...... the same question...

Im getting a new T56 built, and having the gears cryo treated, which is supposed to increase strength.

Another process, although more wear related, is Mikronite treatment.

I wonder would either of these benefit Mini gears/shafts etc ??

Picture of new Minispares "performance" Layshaft.



Looks like the whole thing has been hardened and then ground at the journals.

It looks and feels right but only time will tell.

i think one of the big killers is some of the after market ones has holes which are slightly smaller than the standard ones.

also keep your oil at max as at max the oil is just above holes which feed the layshaft.

Look at a brand new ring gear on a flywheel. Only the teeth are hardened, also the same on a handbrake ratchet and the throw out stop (on the bearing end, the thread is still soft).
