I had to scrap a Yanmar tiller because the oil case was cracked. I saved some of the tines, but also the cover on the gear housing oil fill and the dipstick that goes in it. I heard they were hard to come by. If anybody needs it, I will let it go for a few bucks and actual shipping costs. The tines can also be purchased, but because they were hard to take off, I will need a few dollars for each one, plus shipping. They are well used, but will last quite a bit longer. If I can figure out how to do a Classified Ad, I will post them, but last time I tried, I could see no clue. Here is a picture of the cover and dipstick. The cover is about 2" x 5".
