kasey54 305 #1 Posted October 22, 2019 Good morning all. Recently purchased 417 a and I have read that the 85 model does not have a louvered hood, the 86 does. Mine is the 86 and I'm wondering the pro and con, and why the change. All comments welcome. Pictures later, maybe even today. Share this post Link to post Share on other sites
19richie66 17,532 #2 Posted October 22, 2019 Only thing I didn’t like was rain would get down in the louvers and sit on top of the air cleaner. Not a problem if you have somewhere to store it. I didn’t. Other than that, no other issues. 417-A is a beast. Share this post Link to post Share on other sites
kasey54 305 #3 Posted October 22, 2019 (edited) I suppose any cover would keep the rain out. I was wondering if the engine needed more cooling. Seems to me they had trouble of some sort or they wouldn't have changed it. Edited October 22, 2019 by kasey54 let stuff out Share this post Link to post Share on other sites
The Gman 476 #4 Posted October 22, 2019 Pretty sure that given its an opposed twin..... like the 520 and 418 air flow would be harder to get in the sides then up over the engine to the carb. Straight down is the easiest path. Probably why the changed. Share this post Link to post Share on other sites
19richie66 17,532 #5 Posted October 22, 2019 The 418-A and 8 I believe both had louvers. The 418-C did not. Same engine, but the C was a bare bones no frills work horse. Maybe they just used what they had on hand for certain models. Some had them, some didn’t 1 Share this post Link to post Share on other sites
Cee245 819 #6 Posted October 22, 2019 I have a 417-A that I was told on here that is a 1985. I have the louved hood. Share this post Link to post Share on other sites
JCM 9,636 #7 Posted October 22, 2019 @Cee245 If your ID tag is 31-17KE01 It should be a 1985, if the tag is 31-17KE02 it should be a 1986 unless hoods have been changed ? Share this post Link to post Share on other sites
kasey54 305 #8 Posted October 23, 2019 I'll check that tomorrow. I assumed it was original and a 1986. 1 Share this post Link to post Share on other sites
lynnmor 7,388 #9 Posted October 23, 2019 In my opinion, the louvers are there for appearance only and the lack of weather protection doesn't make practical sense. Share this post Link to post Share on other sites
JCM 9,636 #10 Posted October 23, 2019 I have a louvered hood on my 1991 520-H and use it in the winter with a 44'' 2 stage blower and cab and when I back it into the garage when done I open the hood and wipe the chrome air cleaner cover dry so it won't rust along with the front chrome hubcaps, they sure look nice but another thing to do when putting it away. It may help to keep that big twin cool ? Share this post Link to post Share on other sites
kasey54 305 #11 Posted October 23, 2019 That's possible, I think the smooth hood looks better. 1 Share this post Link to post Share on other sites

BESTDOGEVER 218 #13 Posted October 23, 2019 The Kohlers are physically smaller than the onan engine, if you look at them side by side the rear cylinder on the Kohlers has plenty of clearance and much better air flow and they weren't prone to the damage that the onan was but more air is better 1 Share this post Link to post Share on other sites

Cee245 819 #15 Posted October 24, 2019 (edited) I have the louved hood and if you look REALLY close, it appears that I do have a 1986. I think I see a 2 at the end of the Model number. I can make out a couple numbers of the serial number... Very hard to read. What do you guys think? Cory Edited October 24, 2019 by Cee245 1 Share this post Link to post Share on other sites
kasey54 305 #16 Posted October 24, 2019 I checked mine, and can't read it at all. I feel sure enough its an 86 Share this post Link to post Share on other sites
richmondred01 2,270 #17 Posted October 26, 2019 (edited) To me louvered hoods are much better looking. In the winter during snow a simple metal cover, with a gasket material to protect the paint, is used. It is attached by using a wing nut. I’ve got a few if anyone in interested.
