Bowsers are made up of many components and unfortunately, we cannot get a complete breakdown of each bowser as they have different parts and may vary between customer to customer to suit their specifications.

Coupling Breakdowns:

Trailer Engineering uses Knott Avonride running gear on the bowsers, please find exploded diagrams of the couplings and please see operating instructions for the service manual and spare parts list for the avonride axles and couplings.

Frost Precautions:

When the colder weather comes its important to protect your Bowsers from the Frost, especially the pumps which are open the colder weather. In the below we have a frost precaution in place to avoid pumps from freezing when the colder weather comes.

It is very important to look after your Bowsers when the frost hits to avoid damage of Frozen pumps. Sometimes the water inside the pumps will freeze which could affect them as it makes them expand and crack resulting them not to work.
Please find document with Frost Precautions to help avoid this happening.

Leaking Tanks:

Trailer Engineering has never had a Diesel inner tank leak, this is due to there are no seams for any fuel to leak from. If you have excess fuel in the outer bund of a Diesel Bowser this could be from a number of things, everything from leaving the trigger nozzle open, not venting the tank or filling the Bowser up to much which makes the fuel overflow into the outer bund.

Trailer Engineering now offer a 3 year guarantee on the inner fuel tanks as we are confident that our Inner Tanks do not leak. *see terms and conditions*.
Please find how to identify a “leaking tank” document.
