R792 DHB Volvo B10m 16/12/17 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…

After finishing the front suspension we tasked our self with the renewal of the fuel tank straps.

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…

While awaiting new parts for 25′ s compressor we made a new strap for the exhaust silencer heat shield which had been remade a while ago but not secured to bus.

A job that has been put off for a while was eventually tackled this weekend. Ex Cardiff Lynx (258) has had a compressor head gasket air leak which results in it taking awhile for the vehicle to build up air pressure. This is not a very pleasant job as access to the compressor is not…
