Overdrive ID
Posted: Thu Jun 22, 2023 4:31 pm
Hi all,
Anyone with a 1973-1975 parts book? My 1978 one does not show part number 313241.
The part is a GKN Laycock overdrive. The cardboard it is wrapped in has Dolomite Sprint written on it with felt marker. Inside, tied to the o/d is a luggage label with 313241 2.5pi written on it. The GKN metal ID plate says J-Type with a serial number.
Can anyone provide a definite? I always thought that o/d's were all one type and were the same whether fitted to Jaguar, TR or Dolomite (no knowledge about Rootes Group fittings/types). But as usual I've been disabused of that notion. An A-Type for a Jag might have slight differences to one fitted to an early TR (guess flange wise but other?) and the same with J-Type. My teacher warned me Sherpa van J-Types have pipe differences.
Guess most of you know all that but I'm new to the party. Only have had one issue with a J (blocked filter) and thus never had to expand my knowledge with regard o/d types
