Your Takeuchi's fuel cap is missing, broken, or the lock cylinder is jammed with mud. On a construction site, an unlocked fuel tank is an invitation for theft, contamination, and water intrusion. Diesel contaminated with water or dirt will destroy injectors, score fuel pump components, and create expensive downtime. The Takeuchi dealer wants $97 to $109 for the OEM green replacement cap. That's over a hundred dollars for a plastic fuel cap.
We sell the direct replacement for $49.00 — saving you over $50 vs the dealer. This cap features the same 2-tab bayonet locking mechanism, the same flip-up key cover that keeps mud and ice out of the lock cylinder, and the same scalloped grip edge for easy opening with heavy work gloves. Includes 2 keys. Replaces Takeuchi part numbers 1552101700 and 15521-00500.
The only difference between this cap and the $100+ dealer cap is the color. The dealer cap is Takeuchi Green. This cap is Black. The locking mechanism, the bayonet tabs, the flip-up key cover, the scalloped grip, the seal — all identical. It fits and locks exactly the same way. If you want your fuel cap to match the Takeuchi Green color scheme, the dealer will happily charge you $100 for a paint job on plastic. If you want a fuel cap that locks your fuel tank, this is it.
Takeuchi track loaders use two different fuel cap styles depending on model and production year:
How to check: Look at the bottom of your existing fuel cap. If you see two metal tabs sticking out, this is the correct bayonet-style cap. If the bottom has threads (like a screw cap), you need a different cap.
The 1552101700 locking fuel cap fits the following Takeuchi compact track loaders:
⚠️ Verify your cap style (bayonet 2-tab vs threaded) before ordering. Contact us with your machine model and serial number if you're unsure which style your machine uses.
Why is this cap black instead of green?
The Takeuchi dealer sells the green version for $97–$109 as a dealer exclusive. This replacement cap is identical in function — same 2-tab bayonet, same flip-up cover, same scalloped grip, same lock — but it is made in black plastic instead of Takeuchi green. The $50+ savings is because you're not paying for the color. It fits, locks, and seals exactly the same.
Will both keys work?
Yes. Both keys are identical — they are duplicates for the same lock cylinder. Keep one on your keyring and one as a spare. We recommend storing the spare key in the machine's toolbox or with your fleet records.
Is the seal/gasket included?
Yes. The cap comes with an integrated seal that sits against the filler neck to prevent water and debris from entering the tank.
Can I order this cap keyed alike for a fleet?
This cap comes with its own unique key set. For fleet keying (all machines using the same fuel cap key), contact us — we may be able to source keyed-alike caps in quantity.
