Cast Iron Cylinder Sleeves
Original Message Feb 18, 2005 2:23 pm |

What is the purpose of sleeving the bore of a new engine with cast iron? The ohv Snow King Tecumsehs still have the sleeve while according to my dealer the Briggs Snow Intek does not. I am aware of sleeving being used to keep in service engines that have been bored to the point that the cylinder walls are too thin. Again,why on a new engine? Marc

Hi Pete, I do know enough about cast iron cylinder sleeves Vs. aluminum to say that the answer can get complicated or even become a heated argument. Keeping it simple, and using snowblowers as an example, what actually are the benefits of both? When I look at cast iron, it's usually designed for I/C applications. This enables rebuilding where aluminum blocks may not be worth the expense or not recommended. All things being equal, and an engine is never run low on oil, how many snowblower engines actually wear out and require rebuilding if they are not iron sleeve equipped? As for longevity, is it really worth the expense, if any? If the cast iron sleeve came on a snowblower that had certain features that were very important to me, I wouldn't have a problem getting it, obviosly I wouldn't have a choice anyway. I'm not sure I myself would put that feature as a must have simply as a homeowner. Also, due to the severe weather conditions a snowblower is used, do these cast iron cylinder sleeves rust at all sitting for most of the year as opposed to aluminum. Is it necessary to fog the cylinder at the end of the season? As for aluminum, it's a porous metal and because of that, it does tarnish therefore it can corrode to some degree too. Aside from simply the rebuild factor, which I believe would rarely be the case for a homeowner, I'm not seeing "must have" benefits getting the iron. I'd have to say that if either of these type of engines blew after say, 10-12 years, It wouldn't be unreasonable for the homeowner to just say, "well, time for a new blower" Sorry for all the questions. Richie... What's your point, I said the sleeve is a nice feature, not a deal buster. (for a snowblower) What you mention about the sleeve rusting in the off season is an intersting question. I suspect that the typical lubricationalong with the chrome content would keep things oK for a spell. Many all iron blocks were built for many years. As for your last point I feel sorry for the folks who bout a snowblower they are prepared to scrap at the 1 decade mark for the sake of an engine. Pete

What you mention about the sleeve rusting in the off season is an intersting question. I know you restore many classic snowblowers. Since you get them, perhaps not running condition, I was curious if you have ever come across corroded or rusted cylinders for either of the type of engines being discussed. My point was more curiosity, whether you could elaborate beyond "not a deal buster." Have you seen cylinders with this type of damage whether I/C or aluminum. Certainly was not trying to get under your skin.

okay so i emailed briggs about this and got the answer... it is type number sensitive.. 12D300 cast iron liner 20D300 cast iron liner 20F400 cast iron liner 20A400 aluminum bore. i also called technical services while i was on my lunch break,(the stuff i do for my friends). tech i spoke with said all the intek engines are cast iron liners...i fired him on the spot. he said only the mowers and tillers had the aluminum bores. still not impressed i advised him to get a bit better information. he called me back after he called the "factory"and then told me it depends on the type numbers. i mentioned that it is to hard for a consumer to get this info and that they have to change it in a hurry. thats all for now. later chris

Richie, I think OPE should have a high content of Titanium and Nitinol (memory metal = Titanium and Nickel alloy). It would be light weight and extremely strong. If you did wreck it, you could heat the Nitinol and it would reshape itself! (Great stuff). No more bent augers. We already know about Titanium and it's weight/strength. I would also include a Uranium 235 full cell for Nuclear power. With all of the snow you could cool the blower, supply the water for steam and / or melt the snow with the Uranium; as well as blow in your boxers because it would be very warm. 1 pellet from a Nuclear Power plant is equivalent to 1 ton of fossil fuel, hence clean as anything! Greenpeace, eat your heart out. ( 1 cell could last quite some time). I would also make the power system swap with all my other OPE products. Because of the light weight it would be easy to transfer from mower to blower etc. I wouldn't need a headlight either Green illumination included!!! "Where's your thread " Walt |

Walt,
I love it! Yes, the memory metal is very cool, I've seen it demonstrated. I got a kick out of the "green illumination lighting." When I start the thread, I'll be sure to move this post over to it.
