Gearbox swop?

Post by: **rgh0** » Sat Nov 20, 2010 11:57 am

The normal needle rollers I use have a nylon ring at one end inside the outer case, this acts as a seal (of sorts). Position this seal to the clutch side and it helps prevent water, dirt and dust getting into the pilot bearing. As other have said its a blind hole so only need the seal at one end

cheers

Sorry. I would forget my head if it was not welded on....

This little sketch is courtesy of Andrew. It shows the dimensions etc of the bearing holder for the 5 speed gearbox input shaft pilot (spigot) bearing. The bearing number is the INA number written on the pdf also. Hope this is helpfull to you.. I am about to start making one. The bearing is easy to obtain from bearing suppliers. I had one in my car stock. Much to my amazement.

Many thanks Andrew..

You really ought to use thicker blue string than that.

The braking strain of the 10mm dia Polyprop' rope I used? Well no doubt you will be surprised to learn that it is 1425 KG Bill. Check it out! :shock:

My daughter does that as well, but I gather they get over it when they're about 25.

Is the "Lotus" cover over the front of the car magnetic too? I find that they don't stay in place too well. :roll:

Re.the sketch of the carrier,shouldn't the internal diameter be 0.824?

The bearing is metric at 21.00 O/D x 15 long.

The one I have in my hand is INA (F-331262) and the O/D measures an average of 0.828".
So allowing 2 thou for interferance, and in this case, 0.826" is what I would use, John.

BTW the INA bearing has a nitrile seal at one end.

Sorry Brian,I thought it would be Imperial at 0.825"

John :oops:

Does this mean you don't need a gasket?

What's the matter? Don't you trust me anymore? :cry:

EErrr ..I measured it. Andrew sketched it!

I am just making the internal bore a good but not too tight int' fit to the bearing. Just a light pressure to fit. Not started yet but I will get to it soon...

The release bearing is smaller I/d for the 4 than the 5. To fit the 5 onto the 4 'holder' it need a little sleeve turning up. Which I think means that the std 4 speed lever arm will fit without any mods? Is this correct?

Sue M has also told me that the speedo cables are the same. She only stocks 1 type. ''Fits all Elans''.

Gearbox build is underway. Clutch bits will be with me mid December. Gearbox will be out of the car and on the 'bench' by this weekend.
