1957 Sunbeam Twin-Blade electric lawn mower shaft bushing

I have a late 50's series Sunbeam twin-blade electric lawn mower that I use regularly. The shaft bushing(s) on the left blade has worn out, and there's too much play for me to run it w/o ruining the machine.
It appears that the belt-run cog inside the housing is the part that is supposed to come off of the shaft to get to the bushings, but instead of a cotter pin or other fastener holding the cog in place, it looks like a rolled metal pin that may have been pressed in place.
How do I replace the shaft bushings so I can keep using this great vintage appliance!? I found a website that supplies parts for this model year, but no schematics or user manuals.
Thanks!

Mower Man,

Have you fixed your problem yet? I recently acquired the twin blade/twin chute mower with the same problem. You have to tap the roll pin out with a hammer & punch. A bit of a problem since you have to remove the motor first. Very easy to work on though, only 4 screws to take out for that. If you have any other questions/problems you can contact me via email @ dthomp3416@hotmail.com

Good luck,

Doug

    I aquired one of these mowers as a wedding gift back in the early "60s. Since then I aquired several units in poor or non working condition and fixed one and used the others for my parts supply. I have replaced many belts, bushings, switches and a couple of motors. The motors were my own fault. I loaned the machine and forgot to tell the borrowers how to (or not to) use this mower in tall or wet grass. The bushings need to be oiled at every use. The biggest flaw with this mower is the bushing design. It is flimsy. I looked at replacing the bushings with bearings, but the amount of metal forming the bushing holders just doesn't allow for an easy modification.

    This is a great light and plenty powerful (as long as we keep the blades sharp) which I still use today. I searched to see if there were any machines still out there for sale. I was surprised (shouldn't have been) to see that they have become loveable collectables. So much for more free or cheap parts. That's allright. I have enough to keep it going for another fifty years.

    In the meantime, I made an angle punch to remove the pins so that the belts can be changed if needed and or the bushings can be replaced. That is the only difficult step in the repair procedures. Sunbeam used to carry the parts. I haven't checked for many years, to see if they still are. The bushings can easily be made on a lathe.

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. This website is for vacuums and you would need to contact a local lawn mower shop in the yellow pages, they are amazing about the way they can fix old lawnmowers.

So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
Thanks, Don the Vac Man
Go Ahead. Use Us.

Motor stops and won't restart until a cool down


Bushings or bearings in the motor are no longer good, heat up as the motor turns and seize up.
They are probably replaceable but if the shafts are worn or there is other damage to the bearing/bushing holders then you'll have to replace that too and you might consider getting a whole new vacuum for the cost.
Of course, unplug it before attempting to take it apart.

The main belt on my hoover model u6634-900 windtunnel keeps comming off the motor shaft


  • A list of things to check (unplug vacuum FIRST):
    1. All contact surfaces for belt are clean of build up, that can push belt in one direction
    2. Brush roller is not flip end for end (the pulley on the motor shaft should line up straight with the worn area of the brush roller).
    3. The guard on the bottom (covering the belt and brush sides) is clean and free of build up.
    4. The ends of the brush roller are free of build up and the bushings that slide in the end are inserted in the correct direction, this can cause the brush roller to set at an angle and cause the belt to slide in one direction.
    5. You have the correct replacement belt, I have found the wrong belt placed in the packaging for my vacuum at the factory once before (check manufacturers website).
    6. If the brush roller is extremely worn, it could be time to replace but this is very unlikely.
    7. Rotate the motor shaft by hand and see if there is any wobble, the pulley could be on crooked or bearing has failed causing slop in the motor shaft.

Need to replace main drive belt for sickle bar


Instructions

Put on your work gloves. Check the frame size for your mower. It will either be a 56-inch frame mower or a 76-inch frame mower. When you have determined the frame size, adjust the tractor's rear wheels to the mower's frame size. For 56-inch frames, adjust the rear tractor wheels to 56-inch centers or less. The same rule applies for 76-inch frames.

Back the tractor into a position where you can align its left lower link to the mower's lift link pin. Attach these two parts together and secure the connection with the tractor linchpin.

Roll the tractor and adjust the leveling crank until the tractor's right lower link can be attached to the right link pin on the mower. Use the tractor linch pin to secure the connection.

Attach the upper link from the mower to the lower hole in the tractor rocker arm by using the link pin.

Start the tractor. Using the hydraulic control lever, lift the mower frame assembly slightly and move the mower to the left to allow attachment of the left stabilizer. Place the stabilizer guide under the tractor's left lift link. Position the clamp over the link and tighten the nut firmly

Depending on the tractor type, install the clamp plate or push rod anchor assembly onto the left lower link. Install the push rod on either the clamp plate or anchor assembly.

Shift the mower assembly to the right to attach the right stabilizer. Place the stabilizer guide under the tractor's right lift link. Position the clamp over the link and tighten the nut firmly.

Raise the mower using the hydraulic control, then attach the mower lift spring to the spring links with the pins that have been provided. Lower the mower assembly and turn off the engine.

Remove the tractor power takeoff (PTO) cap and connect the splined end of the mower's drive shaft to the PTO shaft. Secure the connection with the snap coupler found on the yoke.

Rotate the leveling crank to lower the frame, ensuring that it is parallel to the ground. Use the leveling crank lock to secure the crank lever.

How do I find the model number on my sunbeam mixer? I need new mixing blades


Some Sunbeam Mixers don't have a model number stamped on them. However, the service number located on the mixer functions basically as a model number when it comes to replacing parts. Hope this helps.

If the armature shaft is worn there might be a problem, but that would be about the only one, Bushes/bearings can be replaced as can brushes. If the armature shaft is worn, a fix can be formulated but it will require some engineering work. Come back to me if you require any more information on this repair,

Using my unit (owned about 6 years - great service so far) it suddenly quit ... no wind down or 'prelude' like whine - growl - etc. -- it just quit running ... suggestions? clear filters?...


I agree with you having great service because mine only lasted two years. It sounds like the motor just worn out. If you don't smell any burnt electrical then replace the bushing for the motor. Good Luck

Your belt is either stretched or the wrong size or the brush bushings are worn and allowing the brush to wobble or the motor is loose in its housing. You need to check all.
Rotate the brush and try to wobble it from the pulley end.
Flip the belt inside out, it if appears cupped, cracked or shiney and slips easily on and off the brush it is stretched. Generally this unit needs anew belt evrey 6 months, broken or not, they get hot and stretch. Do not buy a new belt by matching size, a worn belt can be 20-30% oversized and not broken but totally useless.
The motor shaft should be cleaned with W/D 600 grit sand paper. Motor should have no wobble in the shaft

Eureka model 4870 belt replacement


- NO WAY AROUND THE END OF THE DRIVE SHAFT TO REMOVE DAMAGED BELT.
  • Following the belt replacement instructions in the manual, I removed the three screws, took off the base plate and removed the brush roll, slipping it out of the belt.
  • Up and somewhat inside the plastic housing I could see the other end of belt going around the drive shaft.
  • But the shaft had no gap around its end to allow removal or replacement of belts. It extended from the motor completely across the space and against the plastic housing.
  • Yikes.
  • I dismantled the housing until the end of the shaft was accessible and found that the problem wasn't the shaft moving out of position.
  • The problem was that the bushing mounted on the end of the shaft for the belt to ride on had slipped over.
  • Ah HAH.
  • I applied some LokTite green threadlocking adhesive (though neither the shaft nor the bushing are threaded) to the shaft, slipped the bushing all the way onto it and put it all aside to set up.
  • Finally I reassembled the machine with a new belt in place, plugged it in, crossed my fingers and hit the power switch.
  • It worked like new! FIXT! And I had only one screw left over. It was a small one too, so I doubt if it was important...heh.
Does your machine have a slipped bushing? You may be able to fix it without taking it apart any more than for a normal belt replacement. Try using a rubber or plastic-tipped forceps or pliers move the bushing back into position. Be careful not to mar the metal as it will chew any new belt to bits in seconds. If you are able to move it, put on a few drops of LokTite, epoxy or some other adhesive to keep it in place. You may be able to avoid sending your vac to the shop for costly repairs.
