Which belt for Myford lathe?

[gareth689Participant @gareth689]

Hi all, just picked up what I think is a Myford ML7.  Never used a lathe before but it was £200 so just had to.

it does however need a belt to go on this part?  I don’t even know what to search to find it, as I’m clueless.

Could anyone tell me what belt I need for this?

Thank you ☺️

Not a Myford owner but probably an “A” section belt.  Wrap a piece of string around 2 opposing pulleys cut at the overlap and measure the result. That should give you the belt length

It’s an A23, as discussed towards the bottom of this recent thread

– do read Hopper’s comments about shims etc. which will be encountered when removing and replacing the spindle!

If you are not used ot working on this type of machine I strongly suggest you do not disturb the spindle but use a link belt instead of a conventional type. Example from “new” Myford:

Other suppliers out there.
You can fit this with just hand tools and no disassembly.

You got a bargin for £200 enjoy!

+1 for the linkbelt, I’ve been using a similar one on my Myford S 7 for about 10 years now.

It’s an ML7, not an S7.

Take the bearing caps off.
Lift the mandrel out.
Move the counte rshaft over to one side after loosening the thrust collar and pulley.
Then fit an new A23 belt.

Far better than the link belts (which don’t fit between the pulley and the counter shaft bracket on early ML7’s).

On a ML7 the belt is an A23 and a link belt has NO benefit. I would not use link belt, it is for lazy ——-s may well slip and cause vibration. Just do the job properly ! Noel.

👍 I’m not a huge fan of link belt either..

Gareth, what region of the country do you reside in?

[John HaineParticipant @johnhaine32865]

Link belts are fine if you use the right one and fit it the right way round.  They do need quite a lot of tension.  At one point RDG sold a belt with moulded rubbery plastic links, but they were useless and did nothing but slip.  I bought a proper one that looks like the current “New Myford” item from RS who stock a range of them:

I’ve used one on my S7 for years and also on my VMB to connect the 3ph motor to the spindle (having eliminated the central pulley which was just a PITA).
