A quick pic:
Greg - Man that deck looks great. I had a bit of time today to pull the deck. Theres a slight wobble on 2 out of three. These blades have seen better days for sure. Believe it or not, they all spin just fine, there's a definitely a slight grind and groan to all three. What to order? Bearings? The speed up pulley I've seen. Not a bad idea.Hi Ed
I have a 316 with the 50" deck. What exactly do you mean by just one blade "bogging"? Is the spindle stiffer to turn than the others? If that is the case,I'm thinking the spindle bearings are pretty much on their last leg. Normal hour life is roughly 500 on the spindle bearings,give or take. There is no tensioner adjustment. Just the spring that keeps eveything stretched. If you are planning to use your 318 for grass cutting,I would suggest getting what JD calls the "speed up" pulley to replace your main center one. It will give your blades a bit more speed. Every little bit helps on these older machines. Any other questions I'm glad to help. What T-Mo suggests (JD Parts) is a good idea also. Very nice of him to offer the pdf's too. You may also find a chute or a cover on eBay or Craigslist.
Greg thanks for the info. I saved everything to a my GreenParts Store wish list. I'm just slowly going to tackle it one section at a time. If I'm rebuilding the mandrels why not powder coat and replace the worn out parts nowHi Ed
Thanks for the compliment. It's not quite that clean now after cutting for 2 summers,but it,and the tractor definitely needed some TLC back then.
I would definitely replace those bearings,they are JD #9296 sealed bearings which are a popular size for alot of decks. At the time,they were around 7.00 apiece. You can find them on eBay a bit cheaper,but they will be China made. The ones from JD were (at the time when I bought them in 2010) made in Japan.I'll take those any day over the other ones.
The speed up pulley is #AM116141 ( current price 72.00). It's a good thing I decided to get it,because I destroyed the stock one removing it. The two end pulleys came off no problem,but that middle one was a bear. I also replaced the center spindle hub #M45273 ( current price 50.00) because the bearings came out just a little too easy which concerned me. It takes the most punishment. I was able to use a press,but I've read where a decent vise and the proper diameter "tooling" will do the job just as good. I also replaced all the snap rings #J2376M (current price 3.36 ea.). I gave the part numbers and prices in case you need them.
Glad to help
