Ford Transit Chassis Cab Extra LWB for MOT Welding.
This Ford Transit extra LWB (Long Wheel Base) had been specially adapted for the customer many years ago to enable it to carry extra long loads. It came in to us for its annual MOT, whilst carrying out the MOT it became apparent that the extension section of the chassis which makes this van an ‘Extra LWB’ was made from a lower quality steel than the original chassis and was in very poor condition.
After removing the body from the chassis we could see what we had to deal with and realised we would have to completely replace the cross member as well as repairing the chassis legs.
The structural integrity of the the chassis legs was still very good and it was just the thin outer skin that was holed and corroded so we decided to sleeve the complete chassis leg to increase the strength of the existing legs.
“MOT Welding on Transit Van”
Once both chassis leg sleeves and tops had been welded into place it was time to align and fit the new cross member, the cross member also supports the prop shaft so needs to be perfectly in line as to not cause any vibrations.
Next job was to weld the top onto the cross member and seem seal and paint the chassis to help keep it protected.
After completing this section there were a few plates to be made for the rear section of the chassis then the welding would be complete and we could refit the body.
Our customer gave us a call as there 2015 Peugeot Expert 2.0 HDI oil light, stop light and engine light had illuminated on his dashboard and the engine sounded really noisy.
We started the van and immediately it was apparent that there was a major oil pressure issue. As we service the van we knew the correct oil and filter had been used so we did a oil pressure test to measure the pressure of the oil that was circulating the engine.
The oil pressure was only 1 bar when it was supposed to be 4.2 bar so we knew there was a problem with the oil pump, after speaking with the customer it was decided to strip the engine to gain access to the oil pump.
Oil pump failure Peugeot 2.0 HDI.
We removed the sump pan and lower engine sandwich plate to gain access to the oil pump and removed it so a visual inspection could take place.
Oil pump vain failure Peugeot 2.0 HDI.
Once the oil pump was stripped it was found that the main vain in the pump had shattered and only half of it remained which caused the low oil pressure.
Oil pump shaft damage Peugeot 2.0 HDI.
We cleaned out the oil ways and replaced the oil pump then performed 2 oil and filter changes 200 miles apart to make sure no remnants of the oil pump metal remained in the engine.
Always remember if your oil light comes on pull over and stop your engine immediately as damaged will be caused if you do not.
This little Citroen C2 came in for MOT but unfortunately failed on corrosion around both rear sills. Once we had removed the side skirts we could see that the corrosion had been there for quite a while but had been hidden by the skirts.
Find good metal to weld to!
When welding for an MOT we need to find good metal to weld to, this might sound obvious but it means that what looks like a small hole of say a couple of centimeters might end up being a 30cm plate due to the metal around the hole being corroded and thin and not suitable for welding.
In the case of this VTS we had to make plates for the inner and outer sill to bring it back to its original strength. After all the welding was completed it was just a matter of under sealing the welds and metal work then refit the side skirts and carry out an MOT retest.
Then hand the car back to its happy customer to enjoy another twelve months motoring.
