The noise coming from my lathe had gotten louder over the past 6 months. From checking various sites and posts I know that reeves drive lathes are not known for being as quite as a step pulley machine. But mine was so much louder now than when I had gotten it several years ago. Then the other day I chucked up a 11.5” by 5” piece of walnut to rough out. The noise got much worse until it just stopped turning. I immediately shut the motor off and tried to turn it back and forth by hand. It was locked up and wouldn’t turn anymore.
I knew this day was coming but I had not been able to find what I needed as far as a good set of instructions as to what is required to replace the bearings. So I decided to document what I did and post it here, so that the next person will know how easy or hard it is to replace the bearing and get their lathe back in working order.

General Disclaimer. I am by no means a formally trained repair technician, mechanic, or general know-it-all. I am posting the information on what I did and I accept no responsibility on how you repair your lathe.

Because I did not know exactly how to remove each piece and in what order to do it in, it took much longer than it should have. Now having done it once and now knowing how to do it, I can disassemble everything down to the spindle in about 15 minutes or less. I know because I’ve taken it apart 4 times trying to fix something else which I will explain later.

Go to the internet and search " Jet 1236 parts ", you should then be able to find several sites that has a parts manual and diagram that you can view and download.
Remove the 4 screws that holds the cover plate over the reeves drive pulley. 1 top, 2 along the side, and 1 bottom back of plate.
I immediately saw why my lathe locked up. Underneath the Reeves pulleys there is a small geared rod that is connected to the speed selector assemble. The locking bolt had come undone and the rod had moved forward and was now hitting along the edge of the pulley. This is why it locked up but not why it was noisy. I already had it in my mind that I was going to replace the bears so I went ahead with disassembling the lathe.

Turn the lathe on and dial the speed down to its lowest setting. Now shut it off and unplug it. This will squeeze the spindle pulley closer together and you will be able to slip the belt off over the edge this way. Slide the belt to the outside edge of the pulley. Slowly rotate it until it rolls off the pulley. It will be tight between the edge of the pulley and the casting but with a little pulling and turning the pulley it will slip past this pinch point. Set the pulley aside.

Using a pair of c-clip pliers, remove the clip from the end of the spindle shaft. Don’t worry about the other c-clips on the spindle, you will have easy access to them once the Reeves drive pulleys have been removed.


Loosen or remove the 2 set screws that are on the outside pulley. Use a magic-marker or measure the distance from the end of the spindle to the edge of the pulley, so you can put it back in the same location.

Now go back to the front of the lathe and remove the 2 screws that holds the speed reducer handle assembly to the front of the lathe. Pull out the whole rod and cover disk.
If you’re lucky the entire reeves drive pulley assembly should now slide off the end of the spindle. I wasn’t that lucky. I popped off the other two c-clips and tried tapping the pulley and spindle from both ends for an hour and never got any were near being able to move the pulley assembly more than 1/8”. Do Not, Do Not, Do Not, take a hammer or screw driver and hit on the edge of the pulley. It is made of light weight cast aluminum and will easily crack or break off.


Here is what I did to get the assembly the slid off.
Use some fine sand paper to just clean up the end of the spindle. You’re not trying to remove any metal just clean up any residue and grit. Now for the secret, trick or whatever you want to call it. Put the speed control lever back in place but with the handle at the highest setting. Now rotate it to the lowest setting. This will push the assembly off the spindle. You may have to pull the speed lever out and rotate it to the highest speed setting again, but I was amazed at how easily it slide off.

You now have easy access to the other c-clip on the spindle next to the bearing. Once this is off, use a wooden dowel rod and dead blow hammer, to drive the spindle towards the tail stock. My bearings stayed in place in the head stock housing. Insert a longer dowel rod through the center of one of the bearings and tap the opposite bearing out. You may have to angle the dowel rod up, down, right, left, to get the bearing to slide out. Once you have one of the bearings out tap out the other one.

I replaced all three bearings in my lathe. If you are going to do the same then you will also need to remove the c-clip from the Shifting Lever bracket and tap that bearing out also. This bearing was more worn out on my lathe then the two spindle bearings. NOTE: It wasn't until after I had reinstalled everything that I found out that this was the cause for the increased noise in my lathe. The central pulley shaft had worn out and increased in diameter. This allowed it to wobble on the shaft as it turned. On the lowest speed setting it wasn't too bad , but when I increased the speed one or two notches the sound got worse. I went ahead and ordered a new set of pulleys from one of the many distributors online. Though the parts diagrams lists each side of the pulley separately, they are now sold as a set. Online you will see that the left side is no long available and is indicated with instructions to call.

I took the bearings to a local gear/bearing supply shop. They were much cheaper than buying them online and I had them immediately. They matched it up to the identification number stamped on the bearing.

Set the Shifting Lever bracket bearing to the side. It is a different diameter and thickness than the two spindle bearings. I sprayed the spindle with WD40 and then used some extra fine sandpaper or nylon woven cloth to just clean up the spindle. Wipe everything off so it is clean and dry. Then lightly apply or spray some white lithium grease on to the spindle. Take one of the spindle bearings and slip it over the long shaft of the spindle. I then set it bearing side down between the ways of the lathe and used a dowel rod and hammer to tap it down onto the spindle.

Then apply or spray white lithium grease to both areas in the head stock were the bearings will go. Take the second spindle bearing and insert it in the rear head stock cavity. Use a larger wooden cylinder to tap it into place.
