IH B414 Information Needed

Good Evening All
I am working on a 1964 IH B414 with a BC144 gas engine. This tractor is mainly used for loader duties around the farm yard and for firewood in the fall. The gas engine is getting very tired and is low on oil pressure and compression so a rebuild is in the future. With the price of fuel and the availability of parts for the gas models it seems like swapping for a diesel would be the route to go.

Can anyone tell me if the block for the BC144 gas and BD144 diesel will bolt up to the 8 speed transmission without the use of an adapter plate. Also curious if the BD154 will bolt up as I have heard it would be a small upgrade to the 144 in terms of cold starts.

Also if possible can someone explain out the difference between the 144's and 154.

Thanks!

ah welcome back to YT! Seems no one wants to step up to
the plate and give your request a go. Well here goes, first
off I really know nothing specific about a B414. All the info I
am giving you was gleaned from the web. I a making a
guess that you are somewhere closer to the manufacturing
point of your tractor in England then I am here in the US. If
that is true there are a lot of things I am not aware of like
the exact difference between the cost of gasoline and
diesel, I do not even know what you call the two of them
there. First I see plenty of parts available for you gas
engine and I do not see that they are really that expensive,
now that is here. From what I see here unless you have a
low hour Diesel engine found to put in your tractor it will be
far more expensive to acquire the used diesel you have to
rebuild, then I am sure before you are set a done you will
likely have $500 or more in parts you will need to complete
the swap over to diesel. Fuel delivery for one. I for one
would just make up your mind to renew what you have.
That may not be what you want to hear but that is all your
two cents will get you thus far.

Thanks for the reply. I can definitely source a running diesel engine from a local tractor salvage for a fair price with the fuel system and hydraulic/PS pump.

I'm just trying to figure out what all interchanges so I can price a rebuild/swap kit to convert to diesel for my engine if its even possible vs a junkyard engine and roll the dice on what it may need.

There are lots of parts available in the US and England however not very much relatively local, all the salvage yards have diesel B series units. For example a reman carb and aftermarket distributor that fit costs roughly $1000 after shipping, duty and tax. An intake/exhaust manifold combo is very hard to find used and have had 0 luck finding new.

To answer your fuel question the price difference is 2 dollars a gallon cheaper for off-road diesel in my area, which is 3-4 hrs north east of the Maine boarder.

We will see what happens.
Cheers

nless you find somebody that has done the same (or reverse) conversion, the only way you may find that answer is to sit down with the parts catalogs and study it out. If you don't have the catalogs, which I can't imagine you not having when considering such a swap, they are online at the CaseIH site.

I downloaded the parts catalog from case IH site. Thanks I never knew that resource existed for these older tractors. I have a service manual in .pdf forum but no parts catalog.

After an evening of crossing part numbers I just thought id post what I found incase this ever crosses someone else's mind. The Bd144 and Bd154 share the same block but the BC144 gas block is different.
