Additional Information

Did you know the OK258 major engine overhaul kit only fits Massey Ferguson TO30 tractors? TractorJoe does, which is why we strive to verify our parts, ensuring they fit your Massey Ferguson properly.

It can be pricey to replace a major engine overhaul kit on the Massey Ferguson TO30. Thats why we sell new high quality major engine overhaul kits direct at often lower prices than even a used Massey Ferguson major engine overhaul kit!

Price is just one part of the equation though- quality matters too. We don't want you replacing your major engine overhaul kit more than you need to, which is why we back our parts with an industry leading warranty. Even if your TO30 is not your main piece of equipment, TractorJoe knows that having it up and running is always important.

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.
