Is there spec for Toro auger shaft bearing play/slop?

I am repairing and repainting a 1980 Toro 421. I got it cheap, hadn't run in years. Had to do the usual fuel system purge and clean. Has surface rust that I will repaint. Everything else runs ok. I have the auger housing and assembly off. I have not worked on snowblower bearings and gear cases much, so I don't have a reference for normal play. There is around 1/8" of back and forth play (side to side) of the auger shaft in the gear case. The whole shaft moves side to side, there isn't much if any lateral play. See pics for visual of the issue, you can see the oil seal movement. I don't want to spend money to rebuild and replace all of the auger system bearings if not needed. (I will replace the main impeller spherical bearing). Also, if I do need to open up the gear case, are there any tips to know?

Thanks for looking.

correction: this unit is my spare 421, not the one I got running. I have no idea how well the motor or the auger works. I decided to take it apart, since the metal was in better shape than the other 421.

Yeah that is the right amount of end play. those seals are are gone with the Schwinn. if you plan on keeping it for any length of time. I would go in and replace all seals, gasket, and clean the whole BLOODY thing up. that auger bearing is more than likely a sealed roller bearing. not that egg crate job thing. if it is dripping from the gasket that keeps the end plates together. if you don't replace it, you are fighting a losing battle.

thanks PS93. Do you mean the impeller bearing? It is the spherical bushing, it may have been replaced, but the parts drawing calls it a bearing, but shows the bushing. (the unit is a 1980 model 38010). Do you know the approximate cost of the seals and gaskets for this. This is my 2nd backup unit, so not sure if I will keep or sell. Also, what holds the 2 auger shaft oil seals in place?

Thanks again.

Paul

Yeah that is what I meant instead of the auger bearing. I REALLY NEED TO GET SOME SLEEP. then they used that egg crate bushing as I call it. the whole gasket shebang should not be more than 25-30 bucks. I just got a spare set 4 "SR" at Johnson hardware the other day. before they slammed those doors shut for good now. the seals seat in the case itself. you will have to pry the old 1's oot with a pick or something. then take a socket that is the same as the outer DIA of the seal itself and tap them back in there. TRUST ME it is not hard to do. any other questions you have PM me. or just call me oot here.

Well, thinking whether to take it apart lasted about 2 minutes. Its apart, and, woo hoo, a quick parts count shows everything is there (sometimes little parts fly away during disassembly). Now off to cleaning. I cant find a service manual for this model (38010, year 1980), only a parts diagram. Are the directions the same from the 1995 724 (I have that manual).

Thanks again PS93.

Is this the same manual you have?

Experience is something you don't get until just after you need it.

1 more question. I assume the bushing in the case on the right is sitting a bit low (in the pic). The 2 stage directions say to bring the bushing to flush with the inside of the case. Do I need to remove and re-seat these bushings, or just press that one bushing into place.?

Just take a socket and a hammer and tap it back in. if it goes oot the other side then you just might need a new 1.
