Plastic cog for tps

Recommended Posts

Anyone have the little orange plastic cog thing for the TPS that mates to the throttle shaft or know where to get it?

Mine is broken.

I was debating printing one, but I don't think petg will stand up to the temps there.

I'm on my phone so here's a link to a picture.  It's missing the little arm to interface with the Tps.

Mitsubishi refers to it as a joint lol. Part # MD608978.

Amayama in Japan still shows they have them in stock, but kind of pricey.

Buy Genuine Mitsubishi MD608978 Joint,injection Mixer Inr;joint,throttle Body Inr. Prices, fast shipping, photos, weight - Amayama

That sure is pricey. That part could be casted using some type of heat resistant poly.

How much would it cost you to cast it?  How about we model the existing part then 3d print it?

All options welcomed!!. Casting would best for the average person without a 3d printer that's looking to repop a few parts for themselves.

I think it's too hot there for petg (most my printer will do)

 

Nylon maybe, but my printer's hot end can't do it.

I can do Nylon and ABS. Probably couldn't get to it till next week though. How soon do you need it?  I never actually messed with printing Nylon but I have several spools.

How hot do you think it gets in the TB? Nylon is good to 420 and ABS 212 from what I'm seeing online.

Just make sure we're all on the same page ... it's this guy we're talking about, right?

I'm gonna try and draw one up now and give a prototype print tomorrow if I have a moment.

I don't need one right away.  I'd be good with either a heat resistant print or delrin.

@techboyI'd think nylon would be best.  I'm not sure how hot it gets there TBH.  It's enough for it to burn a bare hand.

@ssblast20 if @GTRbilletwants to make a few out of delrin in case others would need them as well, I'd rather you send to him, if it would help the community, maybe can be a source for Dad to sell with rebuild kits. Else I'll take it directly @ssblast20.

I just whipped up a drawing.  I'll try and print one out of Nylon or something tomorrow.  If it fits properly, I can always send the file to GTRbillet if he wants to make them from Derlin.  I can save it a bunch of different ways, so hopefully a format he can use.

Excellent.  I use solidworks.  Typically a parasolid or iges file would work.  Looking forward to see what you come up with.

The 2 green ones I made out of ABS yesterday just to test fit them, but I couldn't get them to print right, I keep getting melty inner layer of plastic in the inside for some reason.  I'm not sure why, it's set to solid and high quality.  This morning I made the black one out of Nylon.  I'll test fit it tonight and see how it fits and adjust the file as necessary.  The Nylon is currently set to medium quality.

Sorry it's been so long since I got back to this - busy at work. 

So, the one I made out of Nylon fits on, but I had to really force it.  It's a tad tight, I couldn't even push it all the way down.  I gotta lossen up the tolerances a bit and reprint.  I think it'll be good on the 2nd try.  If so, I'll send GTRBillet the file and hopefully we can get these made out of derlin.
