  • rebuild kit
  • I am looking at a in frame engine rebuild kit part number A1K 140. It is for a Ford Jubilee. The sleeve is for a 3.500 bore. The seller indicates this may be too large for what he thought he would need. Wants to sell as got rid of tractor. What would be the standard size bore, if such a thing as standard? I have a Jube and the price is right at 250 which includes gaskets, sleeves, pistons, rings and bearings. I am new in old tractors and am ordering all manuals and parts books but want to buy to have if need later but not sure about size. Any help I would appreciate. Thanks

  • Re: rebuild kit
  • The only thing in that kit that is usually a universal fit will be the gaskets, and most engine rebuild kits will have lower quality gaskets than you can buy separately. Everything else in that kit is almost guaranteed to be the wrong size or not needed. There is no good way to avoid the process of disassembly, cleaning, inspection, and careful measuring to determine exactly what parts are needed. Waiting for the right parts to be ordered is normal and the only way to do it right. If you have the internal work done by an engine shop, they can get a better deal on just the parts that are needed.

  • If I read you right then never buy a universal kit? Where would you suggest I buy the parts when and if needed to be sure I get what I need and if wrong I can exchange without a hassle? Thanks

  • Re: rebuild kit
  • The only thing in that kit that is likely to be the wrong size is the bearings. You won't know what size bearings are needed until you inspect the crankshaft to see if it has been reground in a previous rebuild or is so badly worn it needs to be the ground in your rebuild.

    The pistons, rings, and sleeves are a "matched set" that are meant to work as a plug and play replacement for the OEM parts.

  • Re: rebuild kit
  • There is a good chance a standard sleeve, piston, ring kit will work in most of these vintage Ford tractor engines, but why assume anything and risk buying any parts that are not needed or will not work? The engine has to be disassembled to determine condition and sizes of crank journals. The crank may need to be reground or replaced. Before buying anything other than gaskets, try to decide how much work you want to do yourself. It may be best to let an engine shop recommend and find the correct parts especially if the engine needs custom sleeves. The bores need to be checked. If the sleeves need to be replaced, pull the old sleeves and confirm that the bores are standard size and if a standard set of sleeves will work. Make a list of all parts/sizes needed, then shopping for the correct parts is easy.

  • Re: rebuild kit
  • There is no doubt that doing a quality engine overhaul requires careful inspection and measurement of worn parts and the reconditioning and fitment of properly sized replacements. But the chances of standard replacement sleeves not fitting properly in a 134 block is miniscule. The vast majority of DIY'ers (and probably a lot of professional shops) simply buy standard replacement sleeves and pistons without measuring and +99.999% of the time they fit fine. That was after all the design intent of using replaceable liners in the block.

    That said the kit being offered to the PO is not an especially good deal. You can buy an in-frame Super Power sleeve kit from YT (no bearings) for $305. IMO at $250 it is not worth purchasing the PO's kit as an on the shelf spare for an engine that doesn't currently need an overhaul. In fact I don't consider the 5-6 cubic engines of added displacement worth the $50 premium YT wants for the Super Power kits.

  • Re: rebuild kit
  • 3.500 is .062/.063 over stock (3.4375) and would be fine in an NAA. Probably what the 140 in the part number indicates - e.g. nominally 140 CID (actually 138.5) - an increase of 5.1 cubic inches from the nominal 134 stock displacement (actually 133.6)

  • Re: rebuild kit
  • Is the tractor running now?
    What is the oil pressure?
    Give it a compression test.
    Check for leaks oil and water.

  • Re: rebuild kit
  • The logical thing to do is get the block tore down and MEASURE what is in it now. Don't go by what someone else said. Why would you buy parts that may not work? Goes for any rebuild. Take block to a reputable shop where it can be boiled and Magna-Fluxed for cracks before buying parts and doing any rebuilding.The shop will be able to dial bore the cylinders and precision mic the crank and tell you exactly what to get, even better can most likely get the engine kit themselves.

  • Re: rebuild kit
  • Tim, thanks but I don't even know if need it for my Jube but considered buying as might need in the future and the price seems right and could possibly get for less. I just wasn't sure about the bore size. When manuals come in I should be able to tell what is standard.

  • Re: rebuild kit
  • In the "manual" section of this website there is a copy of the NAA manual. There is also the I&T FO-19 service manual. It list the piston size as 3.44" diameter x 3.60" stroke. Total of 134 in³. The block bore size for the sleeve is 3.65" I hope this helps.
