Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I just used my 1350 for the first time (bought used about a month ago, but only a year old)... 944.527394 (well the model doesn't show up, but that's the right number - it's a 27 inch OHV B&S 1350 series 305 cc machine) It snowed about 5 inches of snow a couple of days ago and of course I had to deal with the snowplow "droppings" at the end of the driveway. It went through it all pretty good. Good shooting of the snow and no problems with things when I was blowing the snow. I come out to the garage the next morning and I thought 5 or 6 dogs took a leak on my garage door from the pool of yellow liquid I saw. I open up the garage door and see this pool of yellow liquid under the front of the blower and going out and under the garage door. Question, would this be the auger gear oil? It says it takes Ronex ED #1 (Extra Duty) and I think it is yellow in colour, but wow that just baffles me as to how much was there. After that there seemed to be some light green liquid there too. Maybe the other guy coated it with something, but I'm afraid to start the blower for fear of destroying the auger casing. No gas smell and the oil level is perfect at the fill level... Before I start taking things apart, I'd appreciate some input as to what this likely is and what I need to do (new auger gearcase maybe, new auger gasket,) Also good place to get parts in Canada? I see that these are Husky machines, but not sure if Craftsman parts are cheaper than Husky or not. good info in these threads so hoping borat or snowmachine can chime in http://www.abbysguide.com/ope/discussions/32378-A-1.html http://www.abbysguide.com/ope/discussions/33989-0-1.html Cheers

The first thing to do is to confirm where the oil is leaking from. Do that and get back to us. My neighbour thought that he had "blown" his snow thrower motor last season and sent it in for repairs. Problem was that the engine had been over filled and oil was being forced out through the crank case ventilation valve. You may be experiencing the same situation. Trace the source of the oil before you start taking things apart.

thanks borat... will do... I'll take a closer look at things tomorrow. quick glance it seemed there was an oily film around the auger gasket, but it could have been from something else. I'll check the vent valve as that seems to be common. As it was used the former owner could have overfilled it, but I thought I checked that when I bought it and thought it wasn't overfilled at the time. time to do some digging :) Cheers

I have found shopping parts as Husky versus Craftsman seem to be cheaper. You can then pick them up from the various online part sites. You might want to download the equivalent Husky manual to compare parts schematics. My machine is similar to yours but uses the 1450 series B&S.

Thanks borat and snowmachine, Well I literally took the whole thing apart tonight (from the carb to cracking the front end open) and the leak can only be coming from the gearbox assy as everything else is pretty dry... I spoke to someone at sears and they said to just use low temp gear grease as that would act as a gasket. Said it should get me through the winter unless I had already run the gearbox when the oil was drained. I didn't so should be good. Other thing I noticed is that there is some play in the auger shaft at the gearbox assy. I can move it up and down about 1/4 - 1/2"... I was at Sears today and there was no play in the new ones. Could it be that they just "loosen" up when used or is this a symptom of what caused the leak and I should just take the gear assy apart. Seeing as it leaked all of the floor I should likely do some work on it anyway right? (I'll look up the Husky parts too :) ) by belts are 408007 and 407908 I think the equiv Husky ones are TRACTION BELT: Part Number 179092 Cog-V-Belt AUGER BELT: Part Number 183533 I will double check with Husky dealer

That much play in the auger shaft is way beyond normal. It almost sound like the bushings might be missing or completely worn. That's probably why your gear case is leaking. You don't want to operate the machine if it's in that condition. I strongly suggest you fix the gear case immediately. If not, you might be in for some serious damage. How about taking a few pics of the gear box and posting them?

Testing to see if I can post the pics... do you just drag and drop or how do you post pics here? I found that there was some play in the right front auger bearing (looking at it from the front)... I think that's where my play is coming from. Will replace both since the other is likely messed up. Won't touch impeller bearing unless really necessary... Won't use blower until bearing replaced or will likely destroy gearbox even if I do lube the thing up again. why is it so hard to post a picture on this forum? I don't have the insert picture, but I will just cut and paste the link and hope it works. (having same issue as guy on Sept 1st in the how to insert picture thread... http://www.abbysguide.com/ope/discussions/25867-A-1.html http://i787.photobucket.com/albums/yy160/thorntcl/gearbox_zoom.jpg http://i787.photobucket.com/albums/yy160/thorntcl/auger_zoom.jpg http://i787.photobucket.com/albums/yy160/thorntcl/auger_all.jpg Gearbox has two plugs (yellow circles on left of gearbox zoom assy) Cheers 4th edit and I think I got it, but geesh... also why can't I format my threads? Everything gets ignored and just runs all together? Stole the code from another thread where there were pics... perhaps this will post pics now

ahhh ok, now I have the extended text editing capabilities... thanks to whomever adjusted that for me.

Update:  I have taken off the bolts to the gearbox assy and no fluid came out which means the fluid on the ground must have been from the gearbox assy.

I then found that the right bearing (looking at it from the front) seems to have some play so that is likely why the fluid came out as play in the bearing caused the gearbox assy to be forced open.  I will replace the front two bearings.  Tried to take the whole auger assy out, but can't get it to come out.  I believe I have to take the impeller pulley off to allow it to take the impeller and auger assy off...  I don't want to drill out the roll pin like others have mentioned as that would be way too hard to get at with normal tools...

Will try that tonight.

Cheers

Ok, so for an update: I finally was able to get all of the parts and the time to tear the whole blower apart. I replaced all bearings (auger and impeller), but there is still play in the gear box assembly moving up and down 1/2" or so) Had to use a bearing puller and some liquid wrench to get the old impeller bearing off. Also had to use jig-a-loo to get the new impeller bearing on. I topped up the assy with low temp gear oil instead of using gear oil. It seems that perhaps the gasket itself must be bad as there is still a very small leak of gear oil when it was fully topped up, but it just squeezed out a bit and then stopped. I will keep an eye on the gear oil to see if it leaks out, but it ran well and threw the snow pretty far...I'll just have to keep a supply of gear assy plugs so I can keep topping things up. At some point I'll have to change the gasket I suppose, but that seems pretty impossible to get the gear box assy apart. What do you do? Do you take the shear bolts off the auger assy on both sides? Installed new plastic sliders and a new impeller belt (old one had a nick in it)... Thanks for the help...

   If you have replaced the back impeller drive shaft support bearing (on the back of the intake housing barrel) and the two auger shaft bearings (each end of the auger support shaft attached to each side of the intake housing) then I don’t see how you could have a half inch of play at the gearbox.

 

Is the gray gearbox moving up and down ˝ inch?   Is the auger shaft moving ˝ inch?  What exactly is moving ˝ inch?  For the whole assembly, gearbox and rakes to move that much the bearings must have that much slop but you just replaced them. 

 

If the pivot point of the movement is on the left facing side at the left bearing then moving the whole assembly enough to get ˝ inch at the gearbox would be over an inch on the right side end.   That does not seem possible. 

 

If the flanes in the gearbox were that worn then whole auger axle would flop around so you could not throw snow. 

 

It is hard to see how you could have ˝ in inch movement in the gray auger gearbox after replacing the side bearings.

 

For this part:

At some point I'll have to change the gasket I suppose, but that seems pretty impossible to get the gear box assy apart. What do you do? Do you take the shear bolts off the auger assy on both sides?

 

The time to have gotten the auger gearbox gasket was when you took the assembly out to get the back support bearing and the side bearings.  With that assembly loose you pull it out, take out the rake shear pins and slip off the rakes.  You can then unloosen the several screws in the gearbox and pull each half off the rake shaft.  It would have been good to get a look in there and replacing the parts not so expensive. 

 

I could not find an exploded view of the model number 944.527394 so not positive about the gearbox internals.  You can replace most parts with the rakes off and the gearbox opened up.  If the back augerbox seal is worn then you have to slip it on from the back i.e put on over the impeller drive shaft.  That requires taking off the impeller to get the seal in.  That’s assuming you have a single piece auger impeller shaft with a worm on the end.

 

With ˝ inch movement in the auger gearbox I would not use the machine until that’s resolved.

Who the heck filed down those augers?
