Truck and Track Summer 2026 www.truckandtrack.com 4 BUSINESS NEWS In the Spring edition of Truck and Track we featured an article on the VBG “Mechmatic” accessory which cleans and lubricates the coupling automatically. In this edition we will look at another option which VBG has recently added to their range of coupling care products. “Keep it Safe “Kit (Pt No 49-002400) A new accessory from VBG is the “Keep it Safe “kit. Supplied in a handy drawstring bag containing two aerosol cans, plastic wear gauge and instructions. This product is aimed at drivers who have a positive interest in their truck and encourages them to carry out some very basic service and inspection functions that will in the long run keep the coupling safe and functioning correctly. The kit isn’t intended as a replacement for timed workshop servicing and inspections. One of the aerosol cans is filled with VBG “Mech oil” this is the recommended lubricant for all VBG couplings. This lubricant has a special formula and after application leaves behind an oily film on the surfaces it contacts, unlike some aerosol lubricants which can free off seized components but then dry out lose their ability to retain any lubrication properties. It is recommended that the Mech oil is injected periodically through the holes in the couplings metal lid which are covered by the two rubber bungs. Applied in this way the lubricant covers the internal workings of the mechanism and then works its way down over the coupling pin onto the lower jaw bushing. Grease is NOT a substitute and should be avoided at all costs! Grease will not reach and lubricate the internal moving parts within, it simply attracts grit and other road debris turning this into a form of grinding paste causing premature wear of the coupling pin and trailer eye components. The other aerosol can is VBG “electro oil” and as the name suggests is formulated for application to the electric service connections between the truck and trailer. The application of “Electro oil” will help repel water ingress and eliminate corrosion of the contacts. The plastic gauge is a simple coupling pin and trailer eye wear check device. If the gauge slides easily over the ball part of the pin this indicates the coupling pin has reached its wear limit and it is time to fit a new mechanism kit. The mechanism kit is a complete overhaul kit which includes the top portion of the coupling, upper and lower jaw bushings and a pair of wear plates. When the coupling pin has reached its wear limit contact your VBG service provider. They will order and fit the kit of parts to restore the coupling to its “as new” condition. Checking the trailer eye wear ring or bushing is just as easy, using the other end of the wear gauge. If that part of the gauge slides easily through the wear ring or bushing it is worn to the recommended change limit. It should be noted that most of the wear on this component will occur in a North /South direction. In the case of the wear ring this is a shrink fit item. Under no circumstances should it be driven out with a large hammer and drift! Refer to the VBG website for the correct removal and fitting instructions. Inspection, servicing and recording Returning to the inspection and care of the VBG coupling equipment. Many operators have closed their own workshops and replaced them with (R&M) Repair and Maintenance contracts offered by the truck manufacturers and their dealer network. However, in some cases, these contracts do not include ancillary items, such as the coupling equipment! This then begs the question who is taking responsibility for the inspection, servicing and record keeping of this Safety Critical item? It is certain that in the event of a trailer detachment, due to a defective coupling, the Vehicle Operations and Safety Authority (VOSA) will require answers to these questions and will delve into records to find the answer! If the coupling equipment is covered by a R&M contract, make certain that the provider is properly trained and understands the VBG products. The inspection or repair should be recorded. VBG can offer workshop training and support for all its products. In addition, a great deal of helpful information is readily available direct from the VBG website or alternatively a call to the Warrington office will get you the support needed. www.vbg.eu Keeping Your VBG Coupling Healthy Visit us on Stand Y12
