Repair old Osceola Electra 203 auger

I've got 2 of these old augers, one I've been running a 6" Lazer hand auger, and the other a 8" Jiffy chipper. The one that's been running the Jiffy chipper was running fine up until last weekend when it started acting like it was slipping a clutch. I finally got around to tearing it open today, and noticed that the primary drive gear on the motor is completely stripped. Funny thing is, the other gears are all in perfectly good shape. Go figure.

I'm trying to find a replacement gear, but I'm having trouble figuring out what I'm looking for. I've checked McMasterCarr, but can't find anything on their site that fits the bill. I can't get an accurate measurement on the gear pitch to determine if I'm looking for a 14-1/2 or 20 degree pressure angle.

Here's what I've got so far:

Outside diameter = .438"

Bore = .313"

Length = .750"

Tooth count = 12

Would strike master be able to point you in the right direction ? I think they bought ope out

Quote: We didn't manufacture that particular unit and cannot provide replacement parts for it.

Can't say I blame them, though.

If you can't find another one. Could you clean it up with a file and flip it over and use the other end? confused It may run for a little longer anyway?

I'm looking in to that option, I would just switch this power head to the 6" auger. I've got a machinist buddy looking in to mirror-ing the spring pin hole to the other side.

I'm also trying to find an interested party willing to trade their lazer/shaver style drill for my chipper drill. It's a Jiffy with the counter-clockwise (left hand) rotation. Will even throw in the Jiffy 3hp power head (non-running currently).

The other thing you need to look at is the shaft on the gear that this one drives. It may have grooved this drive gear that much because of the wear-play in the shaft. Usually things will not wear like that unless there is some play somewhere! frown

Good thought, I'll have to dig out the caliper and pull some measurements when I get home. I think if there's more than .010" slop I'll see about having the casing rebushed.

I am nothing more than a DIY'er but I wonder about what caused the gear to wear out. Whatever is downstream might have something kaflooey to bind things up and result in this worn gear?

Indeed it did! Turns out that the secondary drive gear bushings are worn out, so under power the gears are only barely engaging. I'm going to have to pull out the old bushings and get some that are undersized to have reamed out. But, I'm going to be doing it AFTER I find a replacement gear. In the meantime, it's a parts unit. frown

      Problems with Yetti

      got this tackled today took about 3 hours to get both sides done. Didnt even get to use a torch....   Thought I was golden with just jacking it up and I could get to everything but no luck. Had to remove the entire axle hub and brake assembly to get to what I needed. Was a pain but still better then taking off the entire pivot arm.    Axle bearings were already greased and in great shape thankfully. Got both leaf springs installed and its ready for the road again.   Probably going to have my electric brakes checked, I am not touching anything with the brake drums. Based on what I saw it doesn't look like my electric brakes have been working anyway. Brakes are nice to have if its slippery out

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
