Hi All,

I got my Lathe, the Excel Pinnacle 1340G, works splendid, no issues with anything. bit noisy in reverse at high speed from the main bearing but fine the other way. have painted up the top half of it and it looks a lot better

Couple of questions for you if you will.

1, I took the lid off the gearbox and the oil looks reasonably new but may be an idea to change it, what type of oil would you suggest goes in there.

2, The carriage seems to be empty of oil, maybe it leaks or maybe not, but again what type of oil should be in there?

3, What type of oil do you suggest for the bed and other parts for general oiling?

Thanks in advance

Robert

A version of the common 1340 Taiwanese built lathe I think. The Grizzly Tools manual probably applies so may be worth picking up the PDF from their website.

Generally ISO 32 hydraulic oil with anti wear additives for the headstock, ISO 68 way and bearing oil for the bed, feed-screws and sides. Most seem to suggest ISO 68 for the gearbox and apron but ISO 32 for the apron is not unknown. Possibly related to whether or not it has a pump feed from the apron to the bed, ISO 68 may be a little too heavy for the pump.

I use Castrol Hyspin AWS 32 and Magna BD68 bearing / slideway oil on my machines following advice from Castrol technical many years ago and have no reason to dispute the advice. Don't use ISO 68 slideway only oil in the gearbox or apron as it will be excessively sticky. Dual rated, like Magna, is probably best but for our use an ordinary ISO 68 oil should look after the bed and slides just fine. Inspector Meticulous would say oil them before starting work, Ordinary Machinist says don't let things get dry.

Is there a manual with/for it? Maybe one for a different supplier’s ‘clone’ might be available, if not?

There is several 1340 lathe manuals available online (The Grizzly is the first):

Even if the manual isn't for the Excel Pinnacle, they are all much the same.

Thanks for all the info Clive, much appreciated.

When you say apron i guess you mean what i called the carriage?

I will get one of those manuals downloaded tomorrow.
