Recommissioning the 1909 Rover 15

One of the oldest vehicles in the Museum collection, the 1909 Rover 15, has been in the workshop for some serious attention over the past couple of months.  Whilst this beautiful vehicle is much admired by visitors to the Museum, and even occasionally goes out to shows such as the Festival of Motoring and the NEC Classic Motor Show, it has been hiding some dark secrets.



The Rover was acquired by the Museum in 2004, having undergone an expensive restoration by its previous owner, but hasn’t been run since its arrival.  Earlier this year, the decision was made to recommission the vehicle to running condition, and in July, Museum Technician Chris Strawbridge set to work.

The first job of course was to change all the fluids, and here’s where Chris discovered the first problem – at some point one of the seals had shrunk, meaning that all of the radiator cooling water had ended up in the oil in the bottom of the engine – and since the oil had been emulsified by the water, it looked likely that this had happened when the engine last ran.

As you can imagine, this water had caused severe engine damage, the worst of which was corrosion on the oil pump drive gears, to the point where there were barely any teeth remaining – Chris is currently having new gears made at a local engineering firm to completely replace the ruined parts.



Next up, when Chris took the sump off, he discovered more play in the big end bearings than you would expect of an engine that has been rebuilt, and his initial suspicion was that this was another casualty of the water leak.  On closer inspection however, he found that the engine had not been assembled properly when it was rebuilt before arriving at the Museum – in particular, parts of the big end bearings had been left with metal burrs attached, meaning that Chris had to strip the lot to get the big ends functioning correctly.

Chris is currently awaiting the arrival of the new gears to replace the corroded ones, and is none-committal about how long the rest of the work will take once these parts arrive, since he can’t be sure what other secrets may be lurking as the work continues.  

Whilst Chris has many years’ experience of working on all kinds of different vehicles, it is the first time he has worked on a vehicle of this age and he is learning a huge amount about it as he progresses with the work.  Chris feels that it’s vitally important to carry out this kind of work and try to keep older vehicles running – otherwise how else will skills and understanding about how they were built and how to look after them be passed on for the future?



If Chris succeeds in getting the Rover running there will be another interesting challenge to overcome in order to put it on the road – the car carries acetylene lamps, and if it is to pass an MOT the lamps must be in working order.   

Calcium carbide powder will have to be placed inside the lamps, onto which water is dripped, producing acetylene gas though a jet, which is then lit to form a sort of candlelight to light up the headlamps.

If and when the lamp-lighting day arrives it will be wonderful to see, and will be a testament to a lot of hard work and patience by a skilled technician – we will keep you informed of Chris’s progress with the Rover over the coming weeks and months.
