5C H/V Indexing Unit

I need to dismantle my unit, after 'finding' it in the shed yesterday whilst searching for something else., as is the norm.

The centre indexing section appears to have siezed up, as I cannot rotate it.

Ive removed all the easy to do bits naturally, and now come to a halt as I have not a clue how to continue.

Help anyone please?

The indexing wheel has Allen socket grub screws in the holes, with four level with the disk at 90°. Any idea what they are all for?

Album added, but photo below of the indexing wheel.

Geoff - It's good to 'find' something you know you have, but not where

Come on guys/gals!

Cannot believe I've stumped the collective wisdom.

Geoff - Well there is always a first.

You need to unscrew the thingy from the watsit

Once again JS doesn't disappoint.

The word . .

'SMART@RSE' . .

springs quickly to mind

I had such hopes on seeing that you posted a response, ah well.

Geoff - Office filing instead of roasting coffee beans Bah.

At the risk of joining JS in the smartarse corner... no experience of that particular unit but:

- tried removing those allen head grub screws then twisting the index ring? Might just screw off...

- There's what looks like some sort of lock nut with spanner grooves (at about 4 and 10 o clock) within the indexing ring and outside the spindle itself. Make up a tool and try rotating this...

- Also be worth poking something down the keyway visible at 3 o clock on the spindle to see where it is engaged with something...hard to see on the pic but I assume the lock nut as above is NOT fixed to it...

- Also poke/shine a light into the hole at 12 o clock - check for another grub screw?

- Bit unlikely given the index hole spacing but you could look for (and feel with your fingers for in non visible section) any holes running radially inwards from the edge of the index wheel - might be more grubscrews...

Sorry Geoff but the truth is I have had no experience of these units or I would have tried to help you

It was just a bump up the list

This is a spin-indexer right?

This re-machining involved a strip-down which might have helped, Geoff, but it seems that Bogs has moved the pictures. Perhaps he will see this and take pity on you.

Failing that, if you PM me with an email address, I think I have a print-to-pdf of the original that I could send you.

There's a pic of the whole unit in his album which may or may not appear below. Not what I understand as a typical spindex.

Hi, I can't help with the dismantling, but the Grub screws are there to prevent the indexing plunger locating in an unwanted index position, you unscrew them from the indexing holes that you want to use (or maybe screw them in, depending on the unit).

Having modified mine (spindexer) per your post (for which thank you very much), you'd have thought that I would realise that too .... but I didn't

There is a small locking tab visible at 11:55 on the picture at the top of this post, You have the small screw already out and need to pry the tab out, then the round nut that has spanner slots in it will turn.You should see the grooves are holding the spanner slotted ring from turning. You can splurge and buy a spanner wrench or use a punch and hammer to loosen it up,

i've just had a quick rummage around the net and it looks similar to the Hardinge HV-4N. This might help:- **LINK**

If it's a genuine Hardinge, take care of it, the current list price is (are you all sitting down?) £4,550.00 !!!!!!!!!!!!

Ah, 'gentle' prodding has had the desired result!

Thanks for all the help.

That tab popped out easily enough, and would have fallen out had I tipped the unit.

Wasn't feeling too bright when I started to take parts off so failed to recognise it for what it was.

Those grub screws will make it easy to index, IF I remember/bother to set them

Will post more photos as I progress.

Geoff - %^*# gardening and Probate yesterday, ditto today.

Cannot believe how long things take to do nowadays

It's now working as designed, having just assembler it.

That ring 'nut' was loosened using the tried and trusted method of blunt screwdriver given a couple of hefty biffs with a hammer.

Once off it revealed the key and keyway, so I gave every moving part a judicious spray of Duck Oil and left it overnight to work some magic if possible. I also pumped slide way oil into the housing through the spring oiler.

Well that overnight turned into a few days, but when I gave the spindle a twist it actually moved!

After a few revs the spindle started to spin quite freely, so I gave up on the idea of trying to remove said item.

That was two days ago, and today I put everything back, and it's now working as it should.

Two more photos added to Album.

Thanks for all the help.

Geoff - Happy bunny am I. Now where the 'bleep' are all the collets?
