Haha, I think it was! update: I received the new union bolt and installed it. Everything is good as new!

This is exactly what I needed. Thank you so much!

Good to know about the option of running different filters with that. Thanks I got the union bolt off. Took a 27mm socket and a breaker bar to remove. I’m estimating it took about 45 ft lbs of force to remove. It is standard lefty - loosey threaded. The threads are damaged on both side of the bolt (see picture). No threadlocker seen on threads. I could probably use a tiny file and clean the threads up okay enough to work, but I’d feel better with a new one.

I didn’t realize it was a bolt either until I started trying to figure out how I was going to replace it. When I looked at a parts diagram, it listed it as a union bolt. I was surprised too. It made sense to me though, union bolts typically being hollowed out bolts that allow fluid to pass through (typically on master cyclinders, calipers, pumps, etc. My mind was at ease when I realized it was a cheap replaceable part.

Thanks a bunch! I found a place last night that has the part and I should have it by Wednesday. I’ll double check the threads of the new bolt to make sure it’s standard “lefty loosy - righty tighty” threads. I’m also going to check the old bolt for threadlocker, seems like it would come with some on there. Yeah, I’m going to be contacting Yamaha for sure. I’m not sure if the dealer is responsible for the oil filter situation, although it’s likely (The filter spun freely after I got some big pliers on it and then about two full turns later it started binding up - damaged threads. I’ve drilled and tapped for many bolts and I know when you get resistance to take it easy and work it back and forth until you get it out/off) It’s no surprise along with my laregely under inflated tires, handlebars situated noticeably to one side, zero play in the clutch lever, rubber band tight chain, front wheel situation, etc. I enjoy doing my own work but this is ridiculous.

So I decided to take my new FJ for a spin. Missing front wheel sensor and all. I took it easy in B mode and got a nice short ride in. I decided to go ahead and do an oil change while I’m waiting for my wheel sensor to come in. The filter was almost impossible to get off. It took about 4 different tools to finally coax it off with some resistance toward the end. I didn’t have to use the screwdriver method but did put some small dents in it. When screwing the new filter back on, I started to feel resistance before the o ring made contact. I backed it off and the threads on the union bolt are chewed up and not true. So I’ll be ordering that too now. Does anyone know if the union bolt that the filter attaches to unscrews clockwise or counter-clockwise? I’ll be searching for torque specification for it too. Thanks!
