Question Gear Box add oil or not??

As shown in the pic, the gear box on my Craftsman (model 247.88830) has a blue plastic plug on the top of it. Should I remove it & put oil in there?

Thanks but there is nothing in the manual about it. Those "sheets of paper" are far too basic to have any info about something this "technical".

Those MTD gearboxes use a type of grease, not oil. I would go with a 00 grease, but MTD probably used MTD Part 737-0300A.

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

Gearbox lube

I have several older Murray built Craftsmans. The manuals on those list using 30 weight oil in the auger gearbox.

Any definitive answer to this? And is the plug designed to be re-usable or is it a "throwaway" type?

When hosing off the salt just now, I noticed some oil on the bottom of the gearbox, so I wonder if its leaking a little. Or maybe my spray had driven some oil from the shaft and it just dripped down the gearbox.

I'd be inclined to think it may be seeping a little. Dry the whole thing off and let it sit for a cojlle days. Heck, if it's not hitting the floor I wouldn't worry about it for a couple years.

NextYearInFlorida: Not to necessarily buy from, but to source the right fluid for any Craftsman, you may want to click on this searspartsdirect.com link below:

b-0247 Parts | Model | Sears PartsDirect&

and then pick "Model Number" in the left drop down menu, then paste your model no. 247.888301 in the right menu. (I inserted Chuck2's model number from OP from last year.)

Then hit "Enter."

Then click on the "Click to Chat" link on the bottom left corner. Then after you have said "Yes" to wanting to buy a part today question, paste something like this in the chat session:

"What type of oil or grease should I put in the gear box?"

This is what the chat rep told me:

Transmission Sae 80w90 Gear Oil | Part Number 730229B | GUARANTEED FIT from Sears PartsDirect

Make sure you fill out the survey questionnaire and thank them.
