Yeah, they don't have the 2489. I did pick up 8 of the 6589 tho. Any reason a 1" screw won't work in place of the 7/8"? Will they bottom out?

Oops. Didn't see this. Hmmm. I can't even find them listed at J&P or Dennis Kirk. I hate ordering from the dealer. They take forever to get anything in. Like a week at least compared to a day or 2 delivered to my door.

Well I don't think too much of McGrath HD in Dubuque and they never have anything in stock.

I think George meant 2486 on the screws. Those are 1" and according to the dealer, nothing special about them. Hardware store ones should work just fine. We'll see I guess.

Neither of the parts are special. Nearly all HD hardware is standard stuff you can get at a good hardware store or bolt depot.

The washers+screw combo (where they won't come off) is called SEMS fasteners. They're one piece because the washer is not slip fit. It has a smaller ID than the threads.

The new, improved washer is a sealing washer. Those can be ordered anywhere and are usually a combination washer and some sort of rubber or nylon insert that seals on the threads. I use 1/2" sealing washers on my breather bolts that I get by the 10 pack from McMaster.

You can use any setup that fits. I've had great luck with the oid style socket head cap screw, washer, and a copper or fabric sealing washer. The copper tends to work better.

Don't go over length on the screw because they're blind holes and you can blow them out. Make sure they're clean of oil too (for the same reason).

I'll add that some bolts are a special length (non standard).
I've bought stainless or grade 8 from Lowes the next size up and cut them to length with a Dremil with no problems.

The stock screws for the covers are 7/8" with captive washers(don't come off). Used with the felt seals. But the updated screws, 2486(used with the 6589 bonded sealing washer) apparently are 1" which is what I got at the hardware store since they don't have 7/8". I'm a little concerned about the extra 1/8". The hole appears deep enough but I'm not so sure about the threads. I could either tap the threads a little deeper or like you said, cut the screws down an 1/8". I think I'll do the latter just to be safe. Snapping one off cuz I ran out of thread would be an inconvenience for sure.

Not sure why a dealer would stock the 6589 and not the 2486 that goes with them. No one else seems to have them either. J&P directed me to the colony set I listed above. Those would look nice but I don't want deal with leaks after the fact either.

Hypothetical question...are these 6589 bonded sealing washers reusable? Say you have a leak and pull the cover. Can you reuse the washers? I would've bought more but they only had 2 more left. Can't hurt to have spares.
Also, I bought a James gasket kit but the stock rubber ones between the rocker boxes and covers are in great shape. I'm going to reuse them and just hang on to the kit in case of a leak. I assume reusing these aren't a problem? Obviously the lower metal gaskets will be replaced.
