EDW 68D – Leyland Atlantean
We gave this bus its annual check over last week and a number of jobs were found needing attention. A lot of small electrical faults were rectified along with some body defects. Also mechanical jobs such as the radiator mountings had worked loose and the engine stop was faulty, we also cleaned the fuel trap and renewed the fuel filters.
Vehicle passed mot but on return from Porth started to develop a water leak. On return to depot we put back on pit and investigated where leak was coming from. It was found an electrical loom had chafed through a heater feed pipe. We removed pipe and put a new piece of hose over hole repositioned loom and refilled system. We then found the coolant level light would not go out so more investigation we found the probe in the header tank feed cable had a broken wire so we made good a repair and the light now works properly. As engineers we like to see warning lights and gauges working properly on our buses as it can stop potential disasters we can ill afford.
After replacing the overhauled fuel system parts we retimed engine bleed system and eventually started bus without using easy start for the first time. Hopefully with more use it should get better, the bus is now with stagecoach at blackwood having attention to its bodywork.

We then finished work on PAX 466f so it will be fit for the running season. Also 792 our Volvo b10m and 41 the Scania open topper are now ready for mot.

The new years jobs started with trying to get tkg 518j our leopard tow bus started. We found that the fuel system was badly contaminated a legacy of not being run for about 5 years, We removed fuel pump and injectors for overhaul. These have now been put back on bus but we still could not get enough fuel pressure up so the lift pump was over hauled as well. The fuel tank has been bypassed so we were feeding clean fuel in via a temporary tank. We now have a problem with the starter motor as it will not turn engine over fast enough to get fuel pressure into fuel pump so that needs to be checked next.
We have now fitted the new bushes into the rear suspension torsion bar and replaced back on Pax 466f.

The last job on this bus was to check over for mot and reposition the wiper arms which that was not as simple as it seemed but success was achieved in the end and they now stop in the correct place.
This weekend we removed damaged rear mudflaps and fitted new ones these will help keep rear of bus clean. Then we fitted rubber packing to tank straps and refitted the fuel tanks back on the bus. We refilled with fuel and restarted bus and checked for leaks all OK. We will now check her over for mot in the new year.
After finishing the front suspension we tasked our self with the renewal of the fuel tank straps. This bus has two separate tanks which both needed removal as the supporting brackets were rusted through as well as the straps. After removal it was decided to renew the outer tank brackets but we managed to salvage the inner tank ones but renew all straps. On inspection we need to renew the outer tank as it to far gone to repair this is on order. Photos are part of the renewal process.
R792 DHB Volvo b10m Both front suspension air bags perished. We had to jack bus body up, deflate bags, remove air filter ducting, pull bags out. We renewed the bags, pistons and top plates as badly corroded, to refit we had to remove front wheels, shock absorber top mounting bolts to get axle down lower enough to squeeze in newly built up air bags and piston. When in position re inflate and check for leaks all OK. Next we had to renew a corroded air tank strap. Our next project is to renew both fuel tank straps which involves removing both tanks, we might have to renew the outer tank as it looks quite badly corroded.
The rear suspension torsion bar metalastic bushes were worn. We removed the torsion bar from the bus and cut out the old bushes. We are now trying to source new ones.
