Chrome oil cap problem

[Freebird]

Have any of you replaced the oil filler cap with the Yamaha accessories chrome cap number STR-4NK27-14-01? I ordered one from a seller off Ebay. It was new and still in the sealed Yamaha package. Though it looked right and if you butted the threaded end up to the threaded end of the stock cap, the size and thread pitch appears to be identical, it should not screw in. It would just start and then bind. The old cap easily spins down. I even wrapped a rag around it and tried gently with a pair of channel locks but it wouldn't budge. Almost seems like the chrome plating on the threads is too thick or something.

The seller authorized a return but did not have another one so I've ordered one from a different seller.

 

Just wondered if any of you have tried this cap and had similar problems. Here is the part that I'm talking about.

From what you're discribing you're probably right. Chrome is too thick?? A conundrum....

I don't remember the part number but I did have a similar issue several years ago. I bought the chrome oil cap off the shelf at my local dealer, got it home and it wouldn't screw in. I returned to the dealer, they verified the part number was correct, so they ordered another one of the same part number and that one fit just fine. Go figure...

A die to clean the threads?? Of course I would just ask for replacement but cleam the threads and they are hidden. Rust??

I had one on my Venture, fit properly the first time, as you suspect, probably a close tolerance fir on the threads and just a bit to long in he plating bath and you have an interference issue, best not to force it, try another one.

I have that cap on the trike and have no problem with it.

I have one from Yamaha on my Red Baron. No problems - screwed it in with my hand and tightened it.

To thick Chrome plating is my guess !

I have one of those, it fits but it is very tight, not easy to spin on/off. As everyone has mentioned think there are different thicknesses in the chrome. It has held up well tho, chrome still looks great!

I think the "I" version fits better and has less whine.....

Well I've returned the first one and ordered another. If this one is the same, I will just forget about it. Show Chrome also makes one that is made like the OEM original cap except chromed. I like the one from Yamaha but if this one has the same problem, will likely just try the Show Chrome version. I'm not going to keep ordering them until I finally get one that is right.

I have the Show Chrome one and it fits properly and looks good after a couple years on the bike.

 

Maybe the Yamaha cap isn't too big....maybe the filler hole is too small ?

I have the Show Chrome cap on mine ,no problem with it.

Just a quick update. I received the second chrome cap and it works perfectly. Screws in easily just like the stock one did. No doubt the first one was plated too thickly.

I am so glad you replaced that oil cap. Now I can sleep! Thanks Boss
