345 update as of 21.07.13

Evening everyone......

Today I have carried out borescope examination on 345's engine and I am pleased to report no issues were found other than general wear and tear.

I noted that some of the piston crowns have distinct signs of poor combustion due to poor injection which usually indicates injectors and pumps are worn out.

Colchester fuel injection who are currently overhauling 345's fuel pumps and testing the injectors reported on Thursday that out of the 4 pumps they have stripped down they have found they are very worn and their operating efficiency was far down from specified output from the pumps.

This was also good news as this confirms that the pumps are the likely cause to the low horsepower issues we experienced when the loco was load bank tested in June,

I am now awaiting an indicative price for the fuel pump overhaul which is likely to be around the £4000 pound mark. The overhaul is likely to take a further week or two to complete.

I was hoping to be able to show you some footage from the borescope checks but unfortunately the LED light on the borescope malfunctioned.

We ended up driving to Mansfield to pick up a replacement unit from Maplins to complete the checks.

A big thanks to John Stephens for his assistance, transport to and from Barrowhill and sorting out the replacement unit

A reminder that D335 will be running at the ELR next weekend taking part in the 45th Anniversary to end of steam (1T57 Gala) Featuring : D9009, D1501, D335 - Steam locomotives - 49395 (Super D) , 80080 (Standard 4 tank), 45407 (Black 5), 44871 (Black 5) & 70013 (Oliver Cromwell).
