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.
497 Daimler fleet line has now been moved to pit 2 ready for brake overhaul.

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.
258 left pit today after a lot of mechanical work had been completed, a service and pre MOT check was also carried out. Some seat cushions now need to be re trimmed and a thorough clean of the bus before a mot test.
More progress on 258. The front doors were not opening properly so the fault was traced to the operating valve in the destination box which was leaking air. We had to modify a Dennis dart valve of which we had a good one in stock by altering the pipework to fit. This done we then found that one of the door ram seals was also leaking air again from stock was renewed. We checked and adjusted the air pressure and the doors are working correctly now. Also the 2 x engine oil filters were renewed along with the fuel filter and the water filter.
Having got the right parts, Bob and Mike set about reassembling the compressor and fitting it back into 258. Below is a photo of all the parts on the table prior to being put back into the vehicle. The pink gasket near the camera was the gasket we had trouble sourcing.
Below is a photo of the area of the engine that the compressor was put back in. As you can see there really not much space to get to it. At part during the refitting Bob was inside and Mike was behind the vehicle trying to get the best access to it.
