Oil Change For Triumph 675
Triumph recommended material has already been discussed in the 675 forum.
Manual recommends running the bike for a while and warming the engine thoroughly before the oil change. Manual aslo recommends waiting atleast 10 mintues after the engine has been shut off to allow sufficient cooling.
Remove the left side fairing. Instructions to remove the fairing is also discussed in the 675 forum here.
Once the fairing is off identify the oil drain bolt and the oil filter.
Unlike some other sportbikes, the oil filter is easily accessible and has enough room to apply some elbow grease.
Remove the drain bolt. Make sure you keep your hands away from the oil that pours out because it’s hot from the hot engine. Let the oil drain into the drain pan.
Remove the oil filter after a while. Some oil will pour out of the filter so be careful because it’s hot as well.
Once the oil has drained take the new oil filter and line the seal with some of the oil itself that was drained or with the fresh oil.
Fit the oil filter and tighten to 7.3 lbf ft (10Nm)
Replace the crush seal if it’s crushed or damaged with a new one and place the bolt back.
I used this oil wrech to remove the oil filter. Sometime some people over tighthen them too much so they can be pretty touch to remove because this particular filter wrench can slip quite easily. We’re going to replace the filter anyway so be imaginative if needed to remove it.
I decided to go with this Repsol Oil.
Notice the specifications that the manual says is highly recommended.
Once the oil drain bolt and the oil filter have been properly fitted, open the filler cap on the right side of the bike and use a funnel to put oil in.
Make sure your bike has enough oil but do not over fill. The following image was taken from the link http://www.triumph675.net/phpBB2/viewtopic.php?t=12301
Replace the fairings and start your engine and let it idle for a while.
