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?

Hi Mints!

Thanks for the info! The dealer didn't know that. I was looking at the ten horse Simplicity. Not clear on the Briggs web site either. The Simplicity catalog doesen't  make that distinction either.Still would like to know what is the advantage of the cast Iron bore liner.

CAST IRON SLEEVE WEARS MUCH BETTER AND WILL KEEP THE ENGINE FROM NEEDING TO BE BORED OUT.

hey folks...

i just so happen to be a master tech for briggs so i emailed them about the snow inteks and will have an answer ...around the turn of the centuary (sp) i couldnt find the answer on the dealer website   wouldnt you guys love to know what is on that site .

the cast iron liners wear much longer and are more resistant to overheating than aluminum liners.

there is also a different piston  and the rings are different.

.

will post the answer asap.

Hi Chris!

I called Briggs after reading Mints' reply. The tech I spoke to said that he needed the spec # off the engine in order to answer. Since I am only shopping and have not as yet bought a machine -no spec #. He suggested I call Simplicity. Might as well try to get Bush to answer your call at the White House!

I was able to see an Intek carb at the dealer and it does have a plastic float. It was not off a Snow engine so no one was sure if the bowl had a drain . The carb as you know is completely enclosed in a plastic shroud so you can't tell without taking it off .

Any information you can find out would be greatly appreciated,

Marc

I think the ones called Powerbilt (or something) are the aluminium engines. Below 10 HP the Intek and powerbilt are pretty much the same. But over 10 HP the inteks have a cast iron bore.

Its my understanding that the same thing happens in other areas such as compressors and for essentially the same reasons:

1. Alumunum is lighter
2. Aluminum is easier to cast and machine;
3. Aluminum disapates heat faster (? I think, not sure)
4. Iron/Steel wears less in a high friction environment.
5. Iron/Steel resists heat deformation better ( less warping)

Therefore most of the housing is aluminum while the heavy wear items such as the cylinders are inserts of the tougher wearing material. Essentially the engineers are trying to optimize the design based on the specific needs of the part. The term "optomize" includes cost to manufacture and material cost as well as performance. That why you don't normally have tungsten liners in retail OPE. Its a balancing act.

Good morning guys!

Last night I went to the "Small Engine Warehouse" web site and checked their stock of horizontal shaft Briggs. They had two Snow Intek Engines with cast iron bores(spec#20D414007&#20D4140019). This information is confirmed by the conversation I had with a Tech at Briggs yesterday . He's the guy who told me that the engines come both aluminum and cast iron bores. He gave me as an example the# 20D4140017 as an example of a cast Iron bore engine. I am going back to the Simplicity dealer this morning to look at the #s on the engine.

This issue of dealers not knowing what is powering the equiptment and what's available is not new to me. Last spring I bought a commercial Toro lawn mower and I had the same issues over the Kawasaki power and what options were available with it and if you could get it in New York etc. The dealers would like to make a sale but the manufacturers don't make the info. available to them. For example I have the new Simplicity catalog and nowhere does it mention word one about cylinder bore construction.Go to their web site and not only is there no phone # to call but in order to send them an Email inquiry you have to give your address and phone # etc.I don' want to give all that info. to ask a question.

Before someone accuses me of being unreasonable in wanting to know about cylinder construction take a look at all of the competitions advertisements. If someone is manufacturing a cast Iron bore engine you don't have to be a detective to find out. 

I called Briggs and they can't tell you what engines are being used on equiptment being manufactured by a company they own!

 .No disrespect intended to "Mints" earlier posts concerning this issue. But when a Briggs factory tech.tells you that the engine comes both aluminum and cast iron you kind of want to nail it down. I think "Mints" is right . Can't imagine Simplicity would use the aluminum cylinder model .

Please excuse my rant but it shouldn't be this hard to buy a Snow Blower,

Marc

your absolutley right...

it really tics me off when im selling more of these snow inteks than any other shop in Nova Scotia and i dont even know about the liner or lack there of.

and whats worse im a master teck for them and that is supposed to mean somthing ,and i still dont have a readily available answer.

but i can assure you when i get to the update school ,the factory rep is gonna hear about this web site and what it means to people here.and i can assure you im not happy about the lack of information that is really available to people that are interested in making informed purchasing decisions.

im sorry i didnt know the engines bore construction,i guess i took it for granted it was castiron lined.but you know if it dosent say that, then it probably isnt.

i will keep you all updated,thanks for the patience.

Marc,
It is my understanding that both are aluminium engines if less than 9 HP like would be in the 860, that Simplicity would have an aluminium bore.

If however you are looking at a 1060 and it said Intek Snow it should have a cast iron bore. The 960, I have no idea.

I am not positve about any of this, it was what I have been told.
