Nozzle Alignment

Correct nozzle alignment is key to a successful installation of your oiler, get this wrong and no amount of adjustment of the flow or inspired installation of the oiler unit will result in an efficiently oiled chain.

The nozzle needs to be in a position where the oil can keep your chain and sprockets clean and well oiled, long experience has found that applying oil to the side(s) of the sprocket is the most effective way of doing this with the minimum amount of wasted oil.

Many people have set the nozzle up so that it drips straight down onto the lower run of the chain, whilst this may seem the simplest approach it often results in excessive amounts of fling and is very good at spraying a fine mist of oil over the whole of the rear of the bike, you are after all, dropping oil onto a rapidly moving component, drops of oil that are more than likely going to be deflected away from the chain by the passage of air at even moderate road speeds.

Please use the following examples to correctly install the nozzle.

Quick Tip!..if your rear tyre has been recently changed make doubly sure that the nozzle has been correctly re-aligned! Tyre fitters may not be aware that the nozzle is even there or know what to do with it. 

The single feed nozzle 

The single feed nozzle should be inserted into the hose adjacent to the internal positioning wire by the barbed end ( indicated by the black band) to ensure a firm, leak free, fitting.

Placing the smooth end of the nozzle into the hose will result in the nozzle being lost.


There are two ways to ensure the nozzle is aligned correctly

1. If your motorcycle does not have a factory fitted Toe/Chain guard then you should use the Shark Fin Nozzle anchor as illustrated below.

The Shark Fin is included in the TUTORO Auto Trek kit.

2. If your motorcycle is fitted with a Toe/Chain guard adjacent to the rear sprocket then you should utilise it as a nozzle anchor as illustrated in the TUTORO Workshop Manual pages 41-43. 

Its important that the Nozzle anchoring cable ties hold the hose to the Toe/Chain Guard in the section containing the internal positioning wire which will prevent the hose from being crushed flat (and cutting off the flow of oil).  Care should also be taken with cable ties holding the hose where there is no wire inside there is no need to pull them so tight that they restrict the flow of oil.

Please note we no longer manufacture the Twin Feed nozzle

Long term extensive testing has revealed that there is no appreciable benefit of the Twin Feed over the Single feed nozzle.

However we have provided the following information to support our customers who already have the twin feed nozzle and wish to continue using it.


The Twin Feed Nozzle

Ideally the twin nozzle is installed so that the tips are touching the sprocket at the 7 O'clock position on the sprocket (assuming a left hand side chain) and that the nozzle tips are lower than the nozzles junction with the oil delivery hose.


This should only be used in conjunction with the Nozzle Anchor kit or the Helix.

A secure rigid mounting is critical for success.

Twin Feed nozzles are not recommend for bikes where the sprocket mounting bolts are very close to the teeth of the sprocket however a ridge such as seen in the 2nd image above, is not a problem, the tips of the Twin Feed nozzle can be located on the inside edge of this ridge.

The Twin Feed Nozzle must be mounted so that the tips of the nozzle are level with each other as illustrated by the diagram below, if the nozzle is twisted and one side is higher than the other oil will only emit from the lower nozzle. It may seem obvious but its also important to note that the rear of the nozzle where it enters the hose should be  higher than the tips of the nozzle where they touch the sprocket.

This is best achieved by using the Nozzle Anchor kit which is designed to allow lateral adjustment by virtue of the threaded rod and vertical adjustment by virtue of angling the "P" clip where it attaches to the threaded rod.

IMPORTANT - When installing the twin feed nozzle it must be aligned so that the sprocket is central to the nozzle i.e. both nozzle tips must touch the sprocket at the same time. If it is not properly aligned then there will be an unequal pressure on one nozzle leading to premature wear and eventually you will find that one tip will miss the sprocket entirely. See Fig 1 and Fig 2 below.

Fig 1.  Nozzle centralised over sprocket. The nozzle tips are resting on both sides of the sprocket face, both tips are exerting the same pressure against the sprocket face resulting in very little wear even over long term use. 

Fig 2. The nozzle was not centralised over the sprocket. Incorrectly aligned at installation, one nozzle tip has worn away and due to the unequal pressure exerted against the sprocket face the unworn nozzle (right hand side n this case) has "moved" away from the sprocket so that its not touching at all.

 The Nozzle Anchor Kit

Note that the back of the nozzle where the hose connects is higher than the tips which touch the sprocket and that BOTH tips touch the sprocket

- A common error is to install the nozzle so that only the outside tip is touching the sprocket, this opens up the "pincer" of the twin feed and leaves a gap so that oil does not get to the inside face of the sprocket.

Also of note is the "p" clip that grips the nozzle on the Nozzle Anchor kit - this goes on the hose at the point where the nozzle is inserted into it, not on the hose an inch or two behind it - This is correctly illustrated in the instructions which come with the kit.




The same care and attention regarding the use of cable ties and the hose detailed in the section above about Single feed nozzles applies to the twin feed nozzle.
