delrin washer in secondary

Two. One under the spring cup, one under the spring. Carl's typical setup. Couple thousand on this setup, and the delrins are still good with no issues.
 
delrins

I've ran 1,2, & 3, and like running 3 the best. LIke said above, 1 under the spring cup, & 1 on each side of the spring. That roller bearing looks cool too.
 
I've wondered about using a thrust bearing like that for years, but never sourced one. Do they recommend any kind of lube for it? Graphite maybe?
 
There's a new roller bearing used by carls now, no more delrin washers being used.

I thought the same thing AK.... looked like the best thing since sliced bread, I've used them before...

Actually Paul Hurley at Fire N Ice was the first to use them back in 2007... But he discontinued them .

For me.... They did not hold up to moisture or any dust/dirt.

They are actually transmission thrust bearings.

made for constant oil bath use.

IMO....As far as the delrin washers for the Secondary TSS clutches....

Both ends of the spring do not need to actually "rotate".... just needs to keep the spring from binding on the 10° [MAX] or so of back/forth twist needed.

Keeping that back/forth minor twist SMOOTH is the goal here.

One end can remain firmly "dug in" so long as the other is free to twist. (it does not need to "rotate"...only twist smoothly)

The purpose of the delrin washers is to allow one end of the spring to slightly rotate, smoothly, as the springs cycles through its compression stroke.

The stock cup does not allow this as the end of the spring digs into the cup and the friction on the steel cup to the sheave keeps it in place.



If you place the delrin washer between the cup and spring, the spring will dig into the soft delrin washer ... not enough to ruin it... but it will have a pressure point on at the spring end.... I know that many have used them IN the cup for years and are happy with it... I was not.

SO... I run two UNDER the spring cup... it does not matter if the spring stays fixed in the cup... because now, the cup will turn.. and you have slick plastic on plastic that allows for ultra easy "twist" of the spring. The 10° of twist will never generate enough heat to fuse them together... and, if you have a clutch that gets so hot you are melting the delrin washers together... You have MUCH MUCH bigger problems that you should address before you are worrying about melting these.


Thats my two cents.

Instructions call for a light coat of wd40, there is a steel washer that goes down first then the bearing and the spring cup on top.

I think there was a aftermarket bearing like this used in the diamond drive? Called shift assist?

Agreed.


Good idea but not the correct part for the application.
 
I am running the Carl's bearing with zero issues and it definitely works better. It is an inexpensive piece. I don't mind if I have to replace it periodically because it is an improvement over the washers.

I agree, big improvement. I now am selling them too in Calgary along with Carl's clutching and even the machined and balanced new clutch. It's just that good.

My thoughts, and how I set mine up, exactly.
