Lescha Hobby 125 S electric mixer requires new drum main bearing

Posted by on

  • Ian Whitehead Oct 28, 2011

    Is your problem still unresolved and is this the mixer with the drum supported by an arched bracket with central spindle and toothed ring-gear around the drum's "waist"?
    If so, you'll probably need an inner and outer bearing. Mine has gone too but I should be checking for new bearings tomorrow and can let you know if you still require them.

I had a similar problem on a Lescha Hobby Mix 120 SF. (Sounds similar to yours) The failure seems to have been caused by corrosion of the ball bearings. If you get water into the rear bearing housing when it is operating, and then store the mixer with the opening in the drum downwards, the water collects around one of the bearings. The bearings are a standard size ball bearing with a 62mm outside dia, 30mm bore and 16mm wide. I bought the sealed version from a local bearing supplier (or look one up on the Internet). The original ones fitted are unsealed, which is part of the problem. I also bought two new bearing retaining external circlips for a 30mm shaft. I had a paint round inside the housing with hammerite, and drilled some 10mm dia drain holes around the outside of the housing near the bolting flange. I also store the mixer with the drum horizontal now.

    how did you fit the bearings in

  • Ian Whitehead Sep 24, 2013

    Hi Terry, if you're still there? Just got back to this long-shelved job! I like your drainage solution/advices and will make those mods when I eventually get the bearing back into the drum housing, which is proving difficult. Did you have to heat the housing up prior to fitting the bearing? I've cleaned out all the old corrosion but I can't get the bearing to enter the housing - it doesn't even want to start squarely yet the shaft bearing fitted OK. Any advice?

  • Terry Apr 13, 2014

    Ian, this was so long ago. I did not remember to check for any responses until I got an email from Fixya yesterday.In case you are still struggling, once the corrosion was cleared out I just found a piece of tube that fitted against the outer race and taped it in with a hammer, I did not have to heat the housing. All was of no avail in the end as after a few minutes use with the new bearings the drive pinion started to jump out of engagement with the outer toothed ring on the drum. the pinion was badly worn, and I could not find a new spare. I even tried contacting the manufacturer in Germany, but no response. I gave up in the end and bought a second hand belle mixer. Anyone want the old one as spares, New bearings and the motor works OK!

    I found you post when looking for parts for the Lescha Hobby-Mix 100S. I think Leonhard (the original manufacturer) is now part of the Altrad Group (at least in Europe)but as far as I can find out, the brand is nolonger support. I am on the second set of replacement bearings, partly due to use, party due to storage as described above. Just got them fitted and the drive pinion is also jumping out of engagement. That is theis weekends job, if its dry.

Maytag electric washer model # lat 9406aae is leaking water from its base, had noticed odd sound during spin cycle as well


Odd sound...? Would this be a nasty grinding sound like a worn out bearing. Nasty sounds and water leaks are usually associated with the main drum bearing breaking up and consequentlly the water seal being breached and water leaking from the back of the drum.

Sorry to say that if this is the case, the cost of repair vs the cost of a new machine are going to have to be considered. If you can get to look under tha machine and see where the water is coming from, you will probably see it is originating from the centre of the drive wheel for the drum. If this is the case then the main bearing is shot. You MAY get a local repairer to come out and replace the bearing (But they will probably need to take the machine away to replace the machine pressed bearing). Or they may offer a refurbished drum and take yours away so they can refurb that later.

Whatever the method, if it is the main bearing, the cost is not going to put a smile on your face and you should seriously consider the alternative of investing in a new machine.

DRYER IS SQUEEKING WHEN IN USE


Main bearing or drum guides are shot - it must be opened up to inspect further.
Grab the drum - and try to move it laterally.
If it moves - your bearing is shot and at almost 2/3 the cost of a new one - repair is questionable.

Transmission question and more


You want the shift drum in to be in neutral. Rotate the shift drum to the point where the sprocket shaft is not turning when the main shaft turns. You are now in neutral. From there you can shift through all the gears by rotating the main shaft as you turn the shift drum to change gears.

Suzuki 125rm manual


Find a manual by Googling " Motorcycle service manuals "
or go to www.repairmanuals.com

Installing new crank bearings is not a simple task. you will need a 3/8" impact driver, flywheel puller, case splitter and torque wrench. The top end comes off then the side cases, flywheel, flywheel electrics, clutch, shifter shaft, Crank drive gear and output shaft sprocket.

Split the case leaving the gears on the shafts and the shift drum and forks in place but out of the gearbox. Remove the crank and then remove the bearings from the crank or from the center casings depending on where they decide to stay when the case splits. Remove the crank seals from each center case half. Install new seals then install new bearings into the center casings.

Now just put everything back together.
By the way, now would be a good time to stick in a new output shaft (sprocket) bearing and seal. Be sure the OHC is timed correctly when installing the cam chain. Bad timing = bent valves.

Kenmore dryer making excessive noise


Likely the main drum bearing in the back. I have seen these go bad, and loud squeaky noise tells you. You can get a new main bearing and replace. It is in the center of the back of the drum, accessee through back panel of dryer usually.
