Sears Auger Gearcase Needed/Brazing Alunimum?
Original Message Feb 8, 2005 1:44 am |

I have exhaustively searched for a left side auger gearcase half for my Sears/Murray model 536.918200 snowblower but have come up empty. The Murray p/n is 50217. The national Murray parts distributor has none & shows part as NLA. The reason I need one is that I accidently BROKE it in two when removing one of the auger rakes. I am considering brazing the broken 2 pieces back together - any tips to make a successful repair? Thanks! Marty

All you guys are AWESOME - I can't thank you enough for the help! Rob - thank you LOADS for the welding offer but it looks like I have a solution thanks to JDavidson! JDavidson - YOU ARE THE MAN!! I never thought of wildcard (*) searching on the website. I cannot thank you enough for posting all your hard earned findings, results AND the part numbers to help me out! The only question I have is which input shaft washers/thrust collar OR needle bearing is used - my old case part numbers or the ones for the new case? Otherwise, I noticed the bushings & oil seals are identical to both style cases. I received prices close to $100 to weld this up which was out of the question. Thanks to "JD" I have a much less expensive alternative which kept this old Sears from either being scrapped or becoming a parts machine! I actually tried to MIG weld this with steel wire (mistake #1). I couldn't see at all, so I didn't use my welding helmet (BIG mistake #2) & virtually had no eyesight over the weekend. USE EYE PROTECTION WHEN WELDING GUYS & GALS!!! REGARDS & THANK YOU! Marty

I was able to reuse all of my original parts when reassembling except for the gasket and gearcase halves. Everything fit perfectly. Only strange thing is one of the halves has a smooth unthreaded hole for adding gearcase lube which you'll have to close off. I was in my local home improvement store recently that has murray snowblowers and they all had the same gearcase design that I just put on my 25+ year old one! I was not sure the parts would work, but was willing to take a chance for $26 plus shipping, I could have always returned them to sears.

Nav - I couldn't believe my ears when I got those prices to make a 4" weld on such a small piece. I ordered everything Wed night (about $70). Once that frozen auger is freed, then all I have to do is reassemble everything. I'll probably paint the auger rakes as they look horrible from all the beating & heating. Then, 4 head bolt threads on the engine need to be helicoiled (they're stripped out), a few machine/engine adjustments, then this guy will truely be like NEW. A word to the wise - if you're reassembling a machine, highly consider using ANTISEIZE on ALL the shafts. This way if you ever have to remove any rakes, pulleys or impellers, they should come off easilly. Marty

not sure what kind of never seize you have available to you but there is a great lube available from your friendly local mercury mercruiser marine dealer. its called mp101 and it will keep stuff in good shape in saltwater which never seize wont do. check it out should be reasonably priced in U.S. later chris

Yipee! All my parts arrived Monday - Sears was very prompt in sending me everything I ordered! Here's the old & new auger gearcase halves: Note that the new case part has 7 bolts to secure the case halves as opposed to the old part's 4 bolts. The new case also offers reinforcing bosses to help strengthen the piece's integrity. I messed up the old case half so badly that I just tossed it... JDavidson - THANK YOU AGAIN for mentioning this to me & for offering your findings & assistance! Snowshoveller - You're not kidding about antiseize getting EVERYWHERE! Even when you think you have it all wiped off, it magically resurfaces... Marty
