Evening All.
Here is an update with work ongoing on 345.
Firstly Colchester fuel injection reported that all 16 fuel pumps from 345's engine were worn out and required mainly new pump elements to be installed and 3 new delivery valves.
It was a relief that they found these issues with the pumps which is likely cause of the low horsepower issue we have experienced during recent load bank trials.
We expect the pumps and injectors will be returned to us within next week or so, however the cost of overhauling the pumps and testing the injectors is in the region of £5000 that we need to find. So if you can spare a few quid please donate it to our loco fund as it would help us out greatly and would be very much appreciated.
Our preservation officer James Bottomley found a fractured bedplate drain pipe which was causing leakage of oil and fuel onto the bogies, this pipe has been re-welded and now free of leaks. Thanks James for sorting this out.
GSMR
The GSMR system has now been fully approved by the ORR (Office of Rail Regulator) which means the loco once full re-certification is granted to run on Network Rail the loco is free to operate in GSMR and non GSMR area's.
A new software update has also been installed to the system in last few days.
The next step.....
Once the pumps and injectors arrive back we shall arrange a working party to re-fit them, run loco up and check for any fuel leaks, check each cylinder is firing etc;
We will then book a further load bank trial with HNRC to check the engine output and re-check engine is cooling correctly. We also need to check traction motor overloads and power earth fault circuits are working as per specification to ensure 345's major electrical equipment is protected.
I suspect when the loco is first load banked its likely that it will be producing too much power and will need to be adjusted down to 1780 HP at the rail as per specification in BR workshop overhaul manual.
Once we are happy with the results we will conclude final exam items and then book for the mainline registration exam to be undertaken and any subsequent corrective actions are completed.
More news soon.....

This blog is to keep all people that are interested in the engineering activities within the Class 40 Preservation Society who look after and maintain our two locomotives D335 (40135) and 345 (40145) for current and future generations to enjoy. Both our locomotives are proudly based at the East Lancashire Railway in Bury, Lancashire. The Society has just spent a great deal of money getting 40145 (345) back into working order. We still need YOUR help!!

D335 Update.
Hello again.
Sorry for lack of reports for last couple of weeks its been a hectic couple of weeks for me.
Today
I and Seton have carried out some work on D335 ready for the weekend. I began
some of the work and Saturday and got it finished off today.
1) Wheel
slip indicator light fault, after some tracing through we found the fault to be
No.1 end multiple working jumper cable wire 21 within the cable
of socket end is life expired or dirty soldered contacts are causing tracking
across the socket. For now the wire has been disconnected from the cab gate and
taped up.
2) No.1
end bogie proportional valve slow release, fault traced to blocked up ports
within relay valve manifold, these have been cleared for now but the manifold
needs to be removed and cleaned out as there’s still rust inside which will
probably cause issues in the future. This will need to be dealt with before
loco moves on national network to the wheel lathe, hopefully in October.
3) No.1
end bogie straight air brake proportional valve, this valve again gave trouble
during 1T57 gala, after stripping again it was found that signal ports where
obstructed with rust as per item 2 and will require the same treatment.
4) No.1
end driver’s door which kept jamming shut has been dealt with today now opens
and closes easily thanks to Seton’s efforts.
5) Loco
has been serviced ready for Saturday.
Andy
Hardman’s Saturday gang are on with painting No.2 cab at present and doing a
sterling job to, already looks cleaner and brighter.
Huge thanks to Seton Spencer for travelling down from Edinburgh to assist me with the work.
If your not aware D335 is booked to work this weekend in lieu of 345 which was penciled in originally for its return to service. The tyre profiles have been checked again and I have given the green light on the loco's use providing that use is restricted and a re-check of the profiles is made regularly.
Further to this D335 will be working our second diesel hauled dining training on 27th September 2013 use link details below for further details on this special working.
