I can send You pictures of the uninstalled set that I have for the DS4, You could get the gears printed out and supply those people that would like to make that purchase.Frankly, batch orders of 200 are ridiculous. In this day and age, you can send off the drawings electrically to a variety of different shops and they can do anything from 1-offs to custom sized batches.
The place I use for all of my water/laser jetting just started doing 5-axis CNC milling jobs in custom batch sizes.
So it can not be reproduced in any manner unless there is some sort of significant changes in the design ?My understanding is he paid a pretty penny to DSG for the right to produce it since they hold the patent.
I’m not for certain on this but I think it is a company in India that is cutting and treating the gears.Well if a guy makes a copy himself, it is unlikely DSG or Leroy would care.
If a guy started making and selling them, thats the hang up.
I’m not speaking for DSG or Leroy- just my opinion on it. I can’t see it would be worth pursuing legal action for someone making a knock off.
And it could be if Leroy was to get set up with someplace like send cut send, then it could be worth doing smaller runs. As it is, I think he it buying full sheets of steel and having the gears, dogbone, axles all cut from the sheet, as well as the bronze bushings.
I don’t know that I would experiment with untreated sheet steel being cut into the gears without the machine work of finishing teeth, but it’s been many a year since ai spent time in a pro shop to know what the equipment is capable of without having surfacing done.
Patents have an expiration date. Design patents typically have an expiration date ~15 years.My understanding is he paid a pretty penny to DSG for the right to produce it since they hold the patent.
I have a set here, in the box just as it came from Leroy Diesel.I took a picture of mine before I had them installed. Unfortunately it doesn't provide any dimensional information. You can count the teeth on it but thats about it.

Nope. That one turned out to be a bad install. Several people (me included) layed the timing chain on top of the time keeper and they are built right. One engine was assembled, pulled chain and installed gears without any rotation and it fit properly.Seems I read where the timing marks may be off ever so slightly.
My plan, when it comes time to install the set, align the marks then rotate the crank slightly back so that the marks on the sprockets hold their positions in perfect alignment.
Pull the chain and sprockets then slide the gear set over the cam and crankshaft and it all should be in perfect alignment.
Thats about all I know about that.![]()
This is good information.Nope. That one turned out to be a bad install. Several people (me included) layed the timing chain on top of the time keeper and they are built right. One engine was assembled, pulled chain and installed gears without any rotation and it fit properly.
There was also the discussion about a 4° advance in the cam but N8in8or disproved that in his optimizer build when he degreed his cam and had to buy the offset key for his advancement.
@ufoDziner maybe you can post on TTS and other sites incase others have one on the shelf they are willing to part with? Remember, a ds4 set will work for you too.
