yeah - wot they said ^^^^^

Yep, did so.
Thank you for looking after my Trixie

changed my oil filter a month or so back (fitted a champion one) and it was a struggle to fit. Must have been too long .

Where is the best place to get a correct sized one?

Thanks

I bought 3 filters on ebay really cheap, it was one original yamaha and 2 hi-flo.
One thing to think of is to get it up in level and then really see to it that you tourque the bolts really even....criss cross...

Hiflo ones from e-bay have always worked. If anyone else is concerned, simply buy a few from your Yamaha dealer. The price difference isn't that bad if it allays fear.

Also for the benefit of neophytes, (i) don't lose the brass insert in the oil filter housing cover into your drain pan and wonder why it's leaking (been there etc.) (ii) your aftermarket filter won't come with the small o-ring that goes with the brass fitting, so you might want to get one from Yam every 3 or 4 oil changes, (iii) when refitting the cover, insert all the bolts by hand and tighten finger-tight by hand, then tighten the rest of the way with a t-handle or L-type allen key. A bit of locktite will avoid any chance of them coming out. IMO, you shouldn't use a torque wrench unless you have a very good small-value wrench with a good allen head socket - those bolts are very easy to over-torque. Don't ask me how I know (I was young and mechanically ignorant, m'lud).

I agree,torqueing up small(M6)hex or cap heads on the oil filter housing is completely unnecessary,there`s O rings for sealing and as long as they are in good condition(still supple and not compressed out of form)bolt tightness really isn`t an issue.
As idl1975 says,a little thread lock(the type you can disassemble)or even a little wipe of silicon on the thread(works in a similar way)will be all you need to be sure of them remaining secure.
I also agree that to tighten by hand/fingers,evenly to start with is very important as you`ll find there is around 3 to 5 mm to compress the filter sealing washer by even when it`s installed correctly.The spigot on the filter fits into the bottom of the small casing that you will have taken off,the spring loaded `valve` face of the filter with the sealing rubber/foam ring faces the underside of the motor.
Some resistance is correct but you`ll notice it`ll be very easily taken up as you tighten(IN CROSS FASHION)the M6 and the larger drain hex headed bolt(the one with a sealing washer under the head).
I buy my oil filters in bulk as pattern parts and because my MuZ Skorpion uses the same filter as the TRX and many other Yamaha`s including my SR 500 it`s normally cheaper too.I`ve NEVER come across any that didn`t fit through being too long and I`ve tried many different types,including `real` Yamaha types,Champion,Emgo,And those sold by Hein Gerrick which I`m currently using.

never had a problem with champion filters from halfords £3.50

Also make sure the rubber seal from old filter is'nt stuck up inside, as it did once for me. That made the filter seem to long, but was just a case of 2 seals together, which would make up about the extra 3mm that you had.

Thanks for that Guys,

Just a couple more questions, I think the filter will only go one way, but just to check, which way up does it go, there is a spring loaded steel button on the filter does that go to the top or bottom?

Also how much oil should come out of the oil gallery bolt? I loosened mine and only a dribble come out, is this right - getting paranoid

Regards

Simon

See my last post on this thread SDN,the filter valve face goes up towards the bottom of the motor the spigot then faces down into the filter housing.
As long as you get a `flow` of oil from the block oil gallery screw you`re fine.

I dont recall ever seeing a spacer in mine ever in any oil change since ive had it maybe the prior owner lost it ? where do i get one ?

Yamaha or make one up on a lathe, 10 minute job for anyone who can operate a lathe.

If i had a lathe or access i would guess ill have to yamaha it does it have a specfic name or just oil filter spacer ?

The part number is: 90387-106W6, & you'll need the O-ring too, prt #93210-12790.
