No I didn't, but they were a standard size, sorry can't remember exactly what they were.

Thanks for catching that. Fixed it. It is the Viton one.

Guarded success!! It doesn't leak now. Truck never got warm enough to engage it, so I don't know if that parts works yet. Again it's 12x3mm O ring from McMAster-Carr 9263K126

UPS just delivered the O-Rings. The 3x12mm one looks very promising and fits very well. I'll try it tomorrow. Too cold and dark to mess with it tonight!

Still waiting. Haven't gotten the Metric O-Rings yet to try. Evans and Comfort Air are still researching it. I did just bite the bullet and buy a replacement actuator through Oshcosh Equipment...ouch. Figure I'll still try to fix the old one for a spare.

So I just ordered some 3mm x 12mm and 3mm x 13mm O-rings from Mcmaster-Carr. Of course you have to order 10 each minimum. What the heck, I'll just throw another $20 at it. By the time I figure it out (if I do) I could have just bought a new actuator for $245.:roll:

Using a micrometer on the worn one, I come up with 2.56mm thick and 12.99mm inside diameter. I found a listing for a metric one 3mm x 13mm. I'm trying to get my hands on one to test it. The original is also not a true O-ring. It's kind of squared off. I think it's also a harder, almost...

Fail! Arrrgh, finally got the parts from Evan's. They weren't sure what O-ring to send so they send me one of each they showed for the actuator. So I ended up with 4 different O-Rings ($5 ea) and none of them are the one I need!:x:x:x:x:x Back to the drawing board. And I still have a...

So, I finally heard back from Evans. They forwarded my email to a parts distributor, I CAN get the seal o-ring from them. They are $20.95 each (plus shipping), which is much better than $245 for a whole new actuator! I wasn't able to call today, but will call tomorrow and order one. I will...

Thanks, that's what I'm finding it's in-between everything. Hopefully I'll hear something back from Evans. I'll try a hydraulic shop next week.

Anyone have any luck replacing the large O-Ring? I don't think it's a standard size. I'm having trouble matching it up. I've emailed the manufacturer, Evans Tempcon, to see if I can get that seal/o-ring.

Looking at the pics from the other thread I see my valve is slightly different. My needle valve in the end cap is just plastic (the white pointy cone). In the others it is brass. I would be seriously ticked-off if I had to pay $250 for a new valve because that little $.05 piece failed. Since...

Had a few extra minutes and decided to pull the guts out leaving the front part in the truck. I found the obvious problem. The big O-ring was very hard and flattened on the outside surface. It wasn't broken, I did that removing it. The 2 smaller ones look fine, but I'll replace them too just to...

Thanks all, I'll do it right and pull it, replace all O-rings. Hopefully that takes care of it.

OMG! I just looked up what a new one costs. You've got to be kidding me!! Are they gold plated?! :shock:

OK I found a good thread with the same issue I am having. http://www.steelsoldiers.com/showthread.php?83932-Actuator-Air-Fan-Clutch-for-M923a1/page5 So now a related question: Could I pull the end off and take the guts out without loosing any coolant? Is the sensor end sealed off from the...

So I started the truck up today to go over some things. Reset the CTIS and I'm still getting the 4 light error (leaking tire somewhere?). The truck aired up, but I noticed the secondary was having a rough time and coming up slowly. Then I noticed a strong hiss and traced it to the...
