Additional Information

Did you know the OK149 major engine overhaul kit fits more than one tractor? TractorJoe does, which is why we strive to verify our parts, ensuring they fit your Allis-Chalmers properly. This major engine overhaul kit is not only made for the Allis-Chalmers D12 tractor, but fits the Allis-Chalmers D14, and Allis-Chalmers D15 tractors as well.

It can be pricey to replace a major engine overhaul kit on the Allis-Chalmers D12, D14, D15, or really any tractor. That's why we sell new high quality major engine overhaul kits direct at often lower prices than even a used Allis-Chalmers major engine overhaul kit!

We back our parts with an industry leading warranty. Whether you have the D12, D14, or D15, it's important to keep your major engine overhaul kit running smoothly. So when something breaks in your Allis-Chalmers, TractorJoe can help.

It doesn't matter if you're installing our major engine overhaul kit in your Allis-Chalmers D12, Allis-Chalmers D14, or something else, we'll be here for you. Our staff knows a lot about Allis-Chalmers tractors, and our Q and A community is there for any other questions you may have.

Frequently Asked Questions
When will I get my items?
Once your items have shipped it takes around 2 to 4 days to arrive at your location. You can track the shipment to find the expected delivery date or if there are any issues that have caused a shipping delay. Destinations outside the continental US will take additional time for delivery.
What if I will not be available to receive my shipment?
We've got you covered! Delivery carriers will generally let you leave a signed note on your door with instructions. UPS will generally leave a ground shipment at the door in rural and suburban locations without a note. You can also instruct the UPS driver to take it back to the customer service center for pickup if you do not want it left. For detailed information please contact the delivery carrier.
Can you ship to an APO/FPO address?
We unfortunately are no longer able to ship to AFO/FPO addresses.
How much is shipping?
Shipping costs vary based on product weights and where you're sending it to. You can calculate shipping costs in the shopping cart or checkout page.
