Noisy headstock on 15 inch variable speed lathe

When running the lathe the headstock makes a lot of noise as if a gearbox was out of oil. It's so noisy that I have to wear ear defenders when using the lathe. Is this normal?

    It is an 11 year old Sears Model 351.21717 manufactured by Palmgren Tools. It doesn't have oil cups or glass gages. I found a phone number for the company on their web site and called their service department. They said the particular model as a gear box that did have a substantial gear box whine but to check the brushes just in case. I checked the motor brushes and they were about half worn so I switched sides and re-installed them. It helped some but it's still noisy.

    I have the same lathe. The gearbox chatters and repacking it with fresh grease only helped for a few hours. I am afraid it is time for a new one since parts for this one are not available.

Usually not. Is lathe leveled, and base secured, check for soft feet. This can set up vibration and load bearings.If motor is belt drive check belt condition, pulley alignment, belt tension.

How do i open the motor to a black&decker 71&2 inch band saw ? my saw has started to make a lot more noise when runing

There are many reasons why band saw make noise. Here's are some "few checks" to do
1. Run the band saw without blade.
2. Run with a different blade.
3. Run the motor alone.
4. Check the bearings.
Another thing; incorrect speeds and feeds can cause noise and vibration.
Regarding about opening the motor, I can't help you with that. Try to check any other band saw motor manual reference.

Ammco 4000 longtravel g/box adjustment not working properly,variable speed adjustment works slowly,then when increased starts to work backwards

What you are referring to is called an "Infimatic" gearbox, or drum-feed gearbox.

The problem lays inside most likely with the clutches.
They are worn out, and possibly other components are worn and broken. Feeding backwards means something has gone terribly wrong--and it needs to be fixed immediately for the machine to operate properly.

These gearboxes are not easy to fix properly--they are literally like a puzzle inside. Our shop employs a infimatic gearbox specialist and we are one of the few shops who can rebuild them to factory spec.

A brand new Infimatic gearbox will run you over $1,300.00 plus tax and shipping from an Ammco depot.

You can ship a broken Infimatic gearbox to our shop for a complete rebuild to factory spec.

I would fusee one of the springs inside the compresser housing has broke and that is why it is noisy especially if your temps remain good. Nothing you can do about that as they cannot be replaced. Good luck

2005 BMW 320D E90 MANUAL TRANSMISSION Hi a noise on my clutch when pushing it down and releasing it just after the free play travel the clutch seems to be 100% still pulls well not slipping or shuddering...

most likely its the thrust bearing noisy but it could also be the layshaft bearings in the gearbox as well ,check the gearbox oil level and check its ok if ok then its a thrust bearing ,these modern motors with a nylon bearing holder are not very good to say the least ,now if oil level is low in gearbox then before you top level up use a grease gun and remove the nipple thing on the end and then pump a good grease gun full of LM grease into gearbox and then top up with EP90 as this will help seal any leaks and stop a lot of the noise ,you cannot hurt anything by putting the grease in the gearbox i do it lot to stop a leaky gearbox from leaking as the grease gets hot and sinks to the bottom and solidifies stopping a lot of the leaks from gear linkages and around the drive shafts although this is a rear wheel drive vehicle so that is less of a problem

How do I change the belt on my ammco 4000 lathe?

I am a brake lathe technician.

To change the drive belt on an Ammco 4000, you must first remove the 90 degree angle PTO (power take off) gear assembly which is driven off the back of the big pulley. Two small allen head screws hold it tight.

Pull the PTO gear assembly out of the disc-feed gearbox. If there are colored shims between the gearbox and the PTO assembly, you must make sure not to loose. If they drop off, be sure to replace them with a dab of grease.

Rotate the red knob at the back of the machine and the motor assembly will unlock and rotate upwards. Replace the drive belt.

To adjust the drive belt tension properly--loosen the 3/4 inch nut on the back of the machine, and the motor will drop down. Tighten the 3/4 inch nut and then rotate the red knob back until the belt is taught.

Replace the PTO gear assembly--making the rotating part with the protruding pin is centered on the big pulley. Tighten the allen head cap screws.

Turn on the machine. If the PTO is making noise--you have not correctly is correctly. Repeat the centering process until the machine runs without rattling or vibration.
