Additional Information

Did you know the OK451 major engine overhaul kit fits industrial/construction machines, and telescopic handlers? TractorJoe does, which is why we strive to verify our parts, ensuring they fit your JCB properly. This major engine overhaul kit is not only made for the JCB 4CX industrial/construction machine, but fits the JCB 520S, and JCB 415 telescopic handler as well.

Whether you have the 4CX, the 520S, or something else, JCB major engine overhaul kits are expensive and thats why we sell major engine overhaul kits direct at significantly lower prices than your JCB dealer. You can save up to 70% with TractorJoe.

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 4CX, 520S, 415, or 410M is not your main piece of equipment, TractorJoe knows that having it up and running is always important.

It doesn't matter if you're installing our major engine overhaul kit in your JCB 4CX, JCB 520S, or something else, we'll be here for you. Our staff knows a lot about JCB equipment, 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.
