Part Numbers - 1985 312-8

[jdleach 525]

Lookin' fer parts. My old PC, with all my links for parts sources, died an ignominious death several weeks ago, and now that I am trying to get the 312 ready for a new season, I am having some difficulty in finding the correct part numbers for my tractor. Found Toro's parts site, but their catalog doesn't go back to my model number anymore. Therefore, I am unsure as to whether the parts numbers listed there are correct. Had a local source for parts, but the owners sold out, and the new owners jacked the prices up significantly, so I figure I will just procure my supplies from online.

 

Here is what I am needing (good source, and correct part #):

1. Mule drive pulleys, inner one (V-style).

2. PTO Thrust bearing.

3. PTO needle bearing seal.

4. 42" deck belt idler pulley. Deck is a Toro, model 78345.

 

If there is a place that has an online catalog for these older Horse parts, I would welcome the link too. Therefore I wouldn't have to bug you fine folks with such queries. At some point, I am intending to get back to work on my 1981 black hood C-175 Hydro, so I will need good sources for those parts as well. 

 

For those of you you who like photos (and who doesn't) here are some pics. I took of the dismantled 312-8 just a few minutes ago.

 

Thanks heaps guys!

We do not have an original parts list so have to rely on the on-line lists. Just remember the 312-8 manual is shared with other models so each item may have more than one part number. ie. 4 item 13's with 4 different part numbers often without a description of what fits what. If in doubt post a question.

The mower deck parts list includes the mule drive. Your deck is newer than the tractor.

You can often save quite a bit by using aftermarket pulleys. Here is a partial list of replacements

The pto parts you need will be the same for each model

The parts that are priced are still available from Toro.

Just got through ordering all the parts I need to get the tractor and mower deck up to snuff. Been burned on the quality of some after market parts in the past, so I went with genuine Toro/Wheelhorse parts. Pricey, yes, but I probably will not have to ever replace these particular items again. Went ahead and got both mule drive pulleys, new spacers (apparently the PO had lost one, and cut a piece of conduit as a replacement), the PTO pulley end bearing, and the mower deck idler. None of the idlers/bearings were significantly bad, just rough feeling and somewhat stiff. I figure that the deck should be quieter with the new belts and pulleys though.
