Thruxton 900 Carb Model Air Filter

[sikatri]

I thought this would be simple. I found that the air filter in place will not come straight out. Made me question if something is wrong or if the filter is not a Triumph replacement filter. I’m wondering if there is something else that needs to be loosened to remove? The manual only indicated 3 bolts and pull filter out. Filter will not come out because a structural member is in the way. Refer to attached pics. Really puzzling.

I’m guessing I’ll have to somehow loosen the air box.

That's very odd.
I don't know anything about the Bobber model, but loosening the air box may be the only solution.
You have to gain some clearance one way or another.

Yes. I’m thinking the box has been off before and there may be slotted holes. I’ll have to see if I can tell how it’s attached.

I’m hoping this won’t mean having to take off the rear tire or disassembling half the bike. This is supposed to be a routine maintenance item. As y’all can see it’s my first time. LoL.

 

[Rocky]

I don't think you have to go to that extreme! This should be fairly routine.
Good luck.

It appears there are four bolts holding the air box / battery housing in place. If there are no other ones restricting movement then this is still okay, but not as simple as I had hoped.

So you have to remove the battery. I didn't expect that, but you are dealing with limited space.

 

[Rocky]

I agree with Greyfell. I didn't expect it to be that hard.

I'll see if removing the four bolts can be done without taking the battery out. All I need is for it to move just a bit. If the air filter was not so rigid with metal ends and metal outer it would not be an issue. It's a matter of a 1/4" or less (5mm or less).

With the four bolts mentioned above the housing will move enough to allow the filter to be wiggled out. Protect the adjacent metal work with a rag or tape. It’s still tight coming out.

I can certainly see the attraction of getting rid of the air box and going for one of those upgrade setups with new jets and a new battery box. For a simple task, I think it could be a bit more simple. I’m going to see if I can position it better and tighten the bolts to give more clearance.

 

[sikatri]

What are the numbers on the bottom? A date?

 

[Rocky]

It was quite a wiggle, but you got it out

Yes, it was. LoL. No idea how old the filter is, but I’ll air blow it this time.

Question. I’ve blown air through the filter as the shop manuals instruct and it doesn’t look dirty. It didn’t look dirty to begin with but I did see some crud come out. My question is earlier this past summer I had some gas drip through the air passage and filter. The filter still smells a bit like gas. Is this a problem?

 

[Rocky]

If it's only a smell of gas I wouldn't worry about it.

 

[sikatri]

If it's only a smell of gas I wouldn't worry about it.

Ok. Thanks. Only a faint gas smell.

My ultimate solution was to delete the airbox.
