Loco restoration news

Recent work has seen the overhauled engine governor fitted, the exhaust bellows to No 1 engine, air tanks under the battery boxes and air filters in No 1 nose end.  The clutch on No 2 roof section has been set up and the clutch drum fitted.  No 2 roof section was then fitted to the loco.  No 1 roof section was then brought in from outside and placed in the workshop ready for the overhaul to start on it.

Quite a list since the last update on this loco: The top end overhaul of 37175’s power unit has turned into a major overhaul, with the replacement of all the main bearings. All the pistons and cylinder heads have been liquid penetrant inspected and heads are now being reassembled. The connecting rods have had the small end bearings replaced and are currently being bolt stretched and reassembled with new big end shells, gudgeon pins & overhauled pistons. Turbochargers and intercoolers have been stripped down for a deep clean and assessment. One of the turbos requires new bearings, the other having had a new set more recently. The timing chain tension has now been set; all cam followers removed, stripped & cleaned; oil filters have been renewed and the strainer cleaned; the roof sections are currently being stripped & repainted.

Last month 37175 underwent ultrasonic axle testing (UAT) as it is over 3 years since this was last carried out. Prior to running again the loco will also require a full air tank inspection & recertification. It is now all hands on deck in an effort to get 37175 ready for its appearance at the Bo’ness & Kinneil Railway’s Scottish Class 37 Golden Jubilee event on 2nd January 2011.
