FAQ r1.6

Oil Container

 

1. Is there an ideal position for the container?

 

Yes!

 

          Vertical, or up to 45deg from the vertical

          Cap pointing upwards

          The breather intake must be at the top of the container (look for the breather's intake hole through the container wall)

          The breather is best routed along the length axis of the bike, with its outlet at least 5cm above the highest point you can foresee the for breather intake (for example, when the bike is on its side-stand). A sufficient length of tubing is supplied to allow the breather outlet to be placed in a good position.

          Bear in mind the usable capacity of the container will be reduced if you do not place the container vertically.

 

 

2. What is the maximum oil level in the container?

 

The container should not be overfilled. This means:

 

          When the bike is vertical or on the side-stand, the oil level should be min. 10mm below the breather intake.

          The more vertical the container is positioned, the greater the quantity of oil that can go in.

          As a guide, the 170ml container actually takes 125ml only (75%). The 170ml figure is the capacity filled to the neck.

          In addition, the more vertical the container, the lower the oil level can be allowed to get before needing a refill.

Why?

          The oil will slosh about in the container with acceleration and braking

          When the container is fairly full it's not so critical

          But when the container is only 20% full, then the scavenge can draw air instead of oil if the pump stroke happens when all the oil is at the other end of the container due to these forces. In the worst case scenario, this could lead to the chain drying out if too many pump strokes draw air

 

Rules of thumb

          maximum 75% full

          the harder you ride, the higher the minimum oil level you need

          the more vertical, the better

 

Note: in a competition environment, it could be useful to use a tall, thin container. Please contact PRO-OILER for solutions.

 

3. Can the container be mounted with the cap pointing downwards?

 

Never!

 

Under NO circumstances may the container be mounted with the cap pointing downwards!

This is a serious safety issue.

If the cap comes off, then all the oil will pour out instantly - and if it all hits the back wheel this could easily lead to an accident

 

There would also be a serious problem with the scavenge for the main feed to the pump, as well as the breather.

 

4. Can I locate the container on its side?

 

Yes, however

          The end of the breather tube must be pointing upwards into the corner of the container nearest the cap.

          Bear in mind the usable capacity of the container will be significantly reduced - you need to keep the container more topped up, and the maximum fill is reduced (see point 2 "What is the maximum oil level in the container")

 

If the cap comes off, then all the oil will pour out instantly - and if it all hits the back wheel this could easily lead to an accident

 

 

5. What's the best way to refill the container?

 

          Pull the brass tube out from the silicone tube connecting it to the feed line to the pump (make sure the outlet of the tube from the pump is higher than the pump itself - otherwise, the tube can drain)

          If necessary, remove the container from the bike

          With a small flat-head screwdriver, turn the screw out in the top 1/2 a turn at a time, pulling/twisting the plug with steady force until it starts to move. Repeat until it does move before wiggling it out of the neck.

          The reason for doing it one-step-at-a-time is that the nut on the inside can (and will) drop off into the oil if you turn the screw too far!

          Fill the bottle, though no more than about 75% 

Tip: use a classic old-fashioned pumped oil can!

          Line up the marks on the bottle and top, push/wiggle the top back in and re-tighten the screw

 

Trying to fill the bottle through the breather is messy.

It can be done, but cyanide kills you quicker!
