We have received some feedback from some of our customers that their crank shaft is broken when they start the Toyan FS-L400 engine. our team is very sorry again for the crankshaft crack failure you have been suffering from. Please note that Toyan has now fully upgraded FS-L400 to avoid the previous problem by changing the inner struction of the cylindeer and adding a bearing on the crankshaft. Basically, only orders shipped before May, 2021 may have this problem. If you have ever seen such YouTube videos of it , then it is obvious that their engine was received at that time. Customers who ship after May will hardly encounter such problems. For those who have received your engine before before May, 2021, you can contact us to get a free new cylinder or crankshaft for replacement if you suffer from crank shaft failure. to avoid fs-l400 crankshaft break problems, Toyan adds a bearing inside the cylinder. it does help solve this problem after testing. as for those who suffer from these problems, please contact stirlingkit team to replace a cylinder, a liner, and a crankshaft for you for free.
Now, we give 4 solutions:
1. If your FS-L400 faces this problem, we suggest you send it back to me to repair, because unfortunately, replacing the crankshaft will not fundamentally solve this problem. Toyan will repalce it with a new cylinder and crankshaft and a liner. The good new is that most of the repaired engines are running well after testing.
2. If you choose to keep it yourself, then we recommend that you contact stirlingkit team to replace a cylinder, a liner, and a crankshaft for you for free. and then please run it at a speed limit within 6k revolution instead of running the engine at a high speed, which help to avoid crankshaft break. Or you can try to add a distributor to convert it into a gasoline version. Of course, you can also make a support on the crankshaft yourself and make an intermediate bearing.
3.The Part #52 is an M3 machine screw. The user needs to drill a hole by himself to tap the M3 teeth, and screw the M3 to the bearing. In this case, it can prevent the crankshaft from shifting along the X axis. That's to say, the crankshaft won't be broke or be suddenly jammed caused by high-speed operation.
Please note that Toyan teams have updated the placed referred above for the orders after the middle of May, 2021. As for the order before May, I recommend you try the instruction as I said before you start this engine.
Any Other problems, please email firstname.lastname@example.org
4. Contact us directly to replace a new cylinder with liner and a crankshaft. please note that the new engine doesn't change the crankshaft at all. the key point is that they add a bearing inside the cylinder, which will help avoid crankshaft failure. this Youtube Video shows where to add a bearing. and our customers who have received the upgraded engine scarcely suffer from these problems.
Some Plans Suggesstion from our Customer Chris Barnes
Chris makes a bush centre bearing to stop it from happening. He believes that he has fixed the problem and was able to run more than 10 tanks of fuel through it without a problem.
