So the other night, the transaxle on my 212 took a crap on me. It sounded like it just kind of exploded on itself. It started running really shaky and before I could get it back up to the barn something popped and it wouldn't move...sounded like a shaking can full of bolts. JD quoted me $900 for a rebuild, so I looked around and found a guy that's got a 212 and a 214 that he is selling together for an attractive price and they come with a front snowblower attachment. They both run but he said the 214 has a rod knocking. I'm going to pick them up in the morning and basically part them out so I have a stash of replacement parts for my 212. I hope to swap the transaxle out in a matter of a couple hours, but I was wondering if there is anything I should look out for. I've yet to have this specific model torn apart but it looks pretty simple and straight forward at a glance.
Also, I'm reading where a lot of guys are putting 80w140 in them, saying it quiets them down and helps them run smoother. Would you all agree with that or should I use JD's recommended stuff?
