  • Cylinder sleeves
  • Short of tearing the engine apart is there a way to tell if you have the 0.040" or the 0.090" sleeves? By the serial number?

  • Re: Cylinder sleeves
  • It's also possible the sleeves have been eliminated for more hp.

  • As stated, Ford originally marked engine blocks with a STAR (*) or a DIAMOND (◊) prefix and suffix. The Star was to designate steel cylinder liners/sleeves, later, in mid 8N production, they switched to cast iron and then used the diamond symbol. This was the SOP for ALL FORD vehicles, not just tractors. Now, if you are asking because you plan on rebuilding your engine and want to buy parts, DON'T. Until you have engine stripped down and cylinders measured, no sense buying any new parts til then. Those STARS and DIAMONDS mean nothing today. Engines were possibly rebuilt before and not always done to OEM specs. Cast iron sleeves are the only ones sold today, I'm 99% sure, so kind of a moot point. Steel liners were not very effective. I've often wondered why FORD marked the blocks anyway. They must have had some inclination that they'd be changing at some point, otherwise why the need to I the blocks? So, my advice is wait til engine is naked and on the way to get boiled and checked before buying parts. Your shop will also be able to tell you if they found any cracks as well.

  • Actually I can find rebuild kits with steel or cast iron sleeves readily on Amazon.
    I really wanted to order the parts before tearing it down because I can't go long without my tractor. I'm almost ready to find another 8N so I can have two, One being rebuilt and one being used.

  • Really? Can you provide a link to a verified supplier of steel sleeves? It's real easy to list something as "steel" - another matter to actually know what you are selling.

  • Re: Cylinder sleeves
  • Here you go sir. My understanding is the 0.040" sleeves are the steel ones correct?

  • You could also have custom made sleeves. I have seen it. No way to know.

  • The star or diamond will tell you what it had in it 65+ years ago when it came from the factory. What are the odds that it's still the way Henry built it?

    And there is also the chance that it someone just removed the sleeves and put Mercury pistons in it.
