This old Lucas service/information sheet describes the workings of the Lucas SW4 windscreen wiper motor. Although un-dated it dates to the 1930s/1940s era, and originally belonged to a garage that has featured a number of times on Old Classic Car - namely Welland's Garage, and is in fact the garage shown at the top of this page, with its proprietor.

Information presented in this section is provided as an aid to classic and vintage car owners only. It shouldn't necessarily be taken as gospel, more of a useful series of pointers. It may be that since these period instructions were created, better ways have since evolved to tackle work on the components being considered. Tips and advice may be given in these period articles, but inclusion doesn't necessarily suggest that anyone involved with OCC endorses the methods portrayed. A certain level of mechanical know-how will be required in undertaking work as described in these pages, and anyone unsure of their own abilities is advised to seek further assistance. Delve into your car's inner workings only if you feel confident in your own abilities, after all - a little knowledge can be dangerous, as the old saying goes.
No-one at OCC can be held responsible for breakages and injuries that might occur, while working on a vehicle following a read of pages hosted on the site. Dabble at your own risk. Where possible, the source(s) for the data shown will be given. If the accreditations are incorrect, or contravene your copyright, please let me know.
