Clutch Adjuster Nylon Screw Split...RT2 #41

UHMP is very good for making bearings out of, but without a lathe with the triple lead with a 10mm pitch facility I guess it's back to the drawing board :).
As mentioned I could have got these made when I worked for GKN without any problem but sadly they shut the factory in 2006.


Same here, just before I retired the company bought a really nice Hass cnc lathe and I got to spend some time playing with it. It's an awesome machine! I think how easy it would be to make these little pieces with that lathe. Unfortunately the company closed that facility soon after I retired.

Call me cynical but looking at the ebay pictures you can actually see the split, very poor seller if they try and sell a part knowingly its defective. I appreciate they say they are not experts but come on, a 3 year old could tell you the part is duff. Hopefully a full refund will be issued.

.

I have a good one of these NOS 256-16340-00 pushers that seem to work well on the DT1/2/3 and RT1/2/3 models, if anyone is interested.

Not as expensive as the one shown in post #6 of this thread, but would still like to get 79.95 for it . . . + Free shipping.
PM me if interested . . . it's going on eBay soon if not needed here.

:)

Has anyone made progress in regards to making the replacement screw section at reasonable cost?

If I were to get a quote on making just the screw sections, what would be tne preferred material?

Return to Nylon and make the bore size so that the screw could press on as original?

Or machine the screw from brass, allowing a light press fit onto the splines with Loctite or similar, and if desired the owner could drill and install set screws.

I would go brass or UHMP which is a great material for making bearings out of it has great wear properties we used to make bearing surfaces out of this stuff it's pretty tough and easy to machine as long as your cutters are sharp. But brass would be as good as you say a nice press fit bore onto the stock splined shaft....job done. Of course you would need to press it on in the right position.

Holding off on getting material machined. Bored as I get over this cold, I did some internet reading and bought some parts off EBay. Should work well as I plan to semi mimic DEETs method.
