MTD help

Hello All!
This past winter, I picked up a Montgomery Wards blower made by MTD(thread https://www.snowblowerforum.com/forum...ds-blower.html). I mentioned that the auger stays engaged after I let the lever go. Also, the gear shifter will stick in spots, resulting in not being able to use all the gears. I was wondering if any of you had any ideas on how to fix either of those.
Also, what can I use to lubricate the drive chain and stuff in the gearbox? I am looking to do a tune up before the snow flies(hopefully not for a couple months)!
Thanks,
Colsanders

The auger staying engaged can be a few things.

1. The belt is too short.
2. The tension on either the control cable or the idler pulley is set too tight.
3. The engine pulley for the auger is rusted bad enough to keep catching.
4. A return spring is broken.

Here are some videos on fixing that:



The gear selector sticking means it just needs cleaned and greased.


Please direct all snow blower questions to the forums and not to me with PMs.

Alright, I cleaned the shifter shaft and greased it. Just like the video showed. I fired it up, and all gears work but first! Any ideas on why first gear might not work?

Sounds like a problem with the friction drive...either worn rubber "tire" on the friction disk or oil/grease on the drive disk. Tip her on her bucket end, remove the access panel and have a look-see. Clean, lubricate and adjust. Make sure the hex shaft that the shifter travel on is clean and lightly greased to promote smooth shifting up on the handle bars.

Could be the shifter is adjusted wrong and 1st gear is so close to the middle it is actually neutral. You can play with the adjustment usually and get faster reverse speeds at the cost of getting slower forward speeds. Sometimes that works out good because the reverse speeds are too slow and the forward speeds are too fast.

If you noticed how it works when you had it apart you will see that there are really no gears inside of there and the friction disc just slides back and forth by the wheel. The further to the outside it is the faster it goes. If you pull it in past the center then it spins backwards for reverse gears.

Could also be you just need to tighten the adjustment gap between the friction disc and plate more so it doesn't slip.

First gear had worked before it was having the problem shifting. Maybe ramming it between gears last winter threw it out of adjustment.

Yea, probably bent the rod some. You can try straightening it out or just adjusting it a bit.

Is there anyplace online that you can think of that sells the rod is connected to the friction disc? I have looked and cant seem to find it. I started the blower up today, and it seems to still stick sometimes from reverse to forward gears.

Thats the pitfall with those older built MTD's. Sadly, there is very little support for chassis parts. You can match some parts with common parts stock, but you have to do the legwork.

On the flip side, these machines are really forgiving, and if you have a deft touch with a small ball peen and an anvil like flat surface, you can work things back into place.

Of course, you could always not worry about first gear, and just throttle it down. Just a suggestion.

Honda HS622 TA-B - acquired at an auction- nice machine for it's size.
Toro S-140- Picked it up on trash day... it runs, sort of.

Did you apply a small amount of lithium grease on the shaft the drive disc slides on? If it's dirty, rusted or dry it wont shift at all smoothly.
