360 3D Printed Crankshaft Locking Tool (AV 3207)

Awesome, great work

 

Awesome!

 

Honestly, this is probably a much better solution that the HE or Ferrari version because it may allow you to lock the crank at or near TDC. You are doing the Lord's work here, John.

My only concern is strength, will it bend or buckle under the stress of loosening the crank pulley bolt since they apparently need to be tightened at 200 million ft lbs?

 

John is very astute with his engineering.

I would be he has taken into consideration the strength factors knowing the application.

I would bet that the file could be converted so the part could also be CNC'd in metal

 

"The reason why I selected the toothed gear over the clutch housing like the factory tool is that the toothed gear offered multiple points where stress would occur, and also the stress would be in multiple directions"

My exact point

This makes far more sense to me than the OEM or HE tools for the reason of the attaching point

Well done, John.

 

Well done.!
I don't have a 360 but the tool should still work for the 430 unless I am mistaken..could come in handy if you want to secure the engine while removing or torquing the PP plate or flywheel.

I see a group buy for F chatters in the future...hoping anyway..
Thanks.

 

Wow john... u da man !! thank you so much.

 

Thanks
Tho I'm not a 360 owner at the moment, I see it in my future.

 

Hi,
Great post here. I am new to 3D printing. I bought an AnkerMake M5C printer and some black AnkerMake PLA+ filament. When I try to remove the bolt the teeth snapped off. I tried printing it a couple more times with the same outcome. I am using 80% infile, 0.2mm thickness, 0.4mm nozzle. The part fits well (first one was warped) but I guess someone over-torqued the bolt. Anyone have a suggestion on a different filament or anything I can try?

 

- Check if the height of your nozzle (relative ro the printers bed is set correctly)

- Changing the orientation of the print might work, but not sure if that is really worth it.

- Adapting the design: wider teeth and radii (i.e. fillets) at the tooth roots

 

Quick Update:
I increased the temperature so that all layers were 230C from 230C for the first layers and then 200C for the remainder. I was able to get the bolt loose after reprinting. Can't wait to get the belts finished tonight and to get the car running again. Thank you EastMemphis for the suggestions and help!

 

@EastMemphis - just want to say thank you for sharing your IP and all here for sharing your best printing practices. For all those who don't have a printer, there are services like Xometry (and many others) that do 3rd party 3D printing - I think if East Memphis is okay with it. But they need guidelines and material specs for printing. I don't plan on purchasing a 3d printer but understand the value.

I am a complete noob at all of this - I am learning on the free Fusion 360 Personal to specifically help on a 360 engine trans swap project which i will shortly announce in the 360/430 forum and one other fchat model specific forum. I am going to be doing some cool stuff and contributing ideas and designs for the greater good, like you guys. So I am sorry if my kindergarten level suggestions here are not helpful.

WAIT.... Ferrari 360 - Fusion 360 !?! I think we have something here!

Since you are discussing printing techniques and such - I recently have been following this guy on youtube. This is all about printing from the car hobbyist perspective. Part of this is a non-commercial for the printer he is using and getting good results. At 12:48 he discusses best filaments for test vs. final working parts and tools. Again, sorry if this is Wheel of Fortune to your Jeopardy conversation. At very least, I feel this guy is one of us and is not cheesy and my kind of humor. He built an off road Viper and is building a land speed car.



Cheers,
Spencer

 

Just tried this today. My 3D printed tool shattered in a three pieces lol
I guess the guy that printed it for me did it differently. Looking at the broken pieces, the part almost looks like a honeycomb on the inside. I expected it to be solid All the way through.
Guess I will be donating an organ to get a proper tool. Lol

 

lol - there is a lot to know about printing! Getting things done, they assume you only care about the outside appearance and they fill the interior with less dense less expensive filler. There is no way a filled one would have enough strength! If you tried hard enough, you could probably crush it between your fingers.

 

The honeycomb inside is typical for 3d printed parts (It significantly reduces weight while keeping reasonable mechanical properties.)

Perhaps it

Yeah, parameters matter. I have the HE tool, if not, I'd print with the settings specified by @EastMemphis (i.e. 80% infill).

 

FYI - I bought the Hill tool from an Fchatter. Mine is not perfect! The screw holes do not line up exactly! Mine needs to be modified to increase the slot widths to be able to use their shoulder bolts.

 

Agreed. I didn't try, but I'm pretty sure I can snap in half with my hands. Sure does look cool, though! Lol


I'm bummed. He printed it for free, so my plan was to use it and then give it away to the next guy who needed one. Trying to save somebody a few hundred dollars.
For the price of a 3D printed part, I can buy my own printer and do it the right way, then hand those out for enough to cover the cost of filament.

 

I used John's crankshaft locking tool when doing a timing belt service and it worked perfectly. Its a really great design and easy to print. I also used his cam locks and crankshaft socket adapter. Both worked flawlessly. Made the job so much easier. I can't thank John enough for providing these to the community.

All were printed with Elegoo PLA on my Bambu X1c.

Just want to say thanks to @EastMemphis for making these tools available. I'm sure others have done this 1000x, however just need to continue to state they're extremely helpful and designed well and great for the community.

 

How are people getting their driver side belt cover off without removing the cooling pipe? I don't recall that being possible...

When I got my car, inspecting the belts was one of my highest priorities and I couldn't get the cover(s) off.
