mints53 Posted September 29, 2017 Report Share Posted September 29, 2017 Hi All I have recently arrived home after a couple of thousand mile trip in my 4a. All went well but a couple of improvements were revealed as desirable. The dynamo output is only marginal. It struggled when I was stuck in traffic in the rain at night and then the kenlow cut in. I would like to convert to an alternator; any tips and words of advice in doing this? I suffer with a whining diff which on short trips with the top down is not a problem. It becomes somewhat tiring after a couple of hrs cruising at 70mph. Does anyone have any suggestions as to where to go to get it rebuilt or replaced with an exchange unit. I am based in the UK (Bucks) Thanks Andy Quote Link to post Share on other sites
RobH Posted September 29, 2017 Report Share Posted September 29, 2017 (edited) Andy- if you do a search you will find loads of info on alternators on the forum. There was a discussion only a couple of months back. The main theme which always ensues is whether to stick with the wide fanbelt or to change to a narrow one. Your choice- either will work. http://www.tr-register.co.uk/forums/index.php?/topic/62977-alternator-fail/ http://www.tr-register.co.uk/forums/index.php?/topic/42443-ammeters-and-alternator-upgrades/ http://www.tr-register.co.uk/forums/index.php?/topic/40296-dynamo-alternator/ http://www.tr-register.co.uk/forums/index.php?/topic/50320-dynamator-alternator-conversion/ Edited September 29, 2017 by RobH Quote Link to post Share on other sites

badhuis Posted September 29, 2017 Report Share Posted September 29, 2017 I had the same issue - dynamo not up for it for the elec fan in combination with lights on. Because I was not happy with the old (front mounted) electric fan I opted to go for a Revotec fan which is mounted at the rear of the radiator (using their brackets) and made it possible to remove the mechanical fan. I had a NOS Lucas alternator and bought small pullies for the water pump and crankshaft. Very happy with the result. Quote Link to post Share on other sites

brenda Posted September 29, 2017 Report Share Posted September 29, 2017 Hi mints53 looks like he is a member, we had to change to a alternate and narrow belt as we do a lot of night driving so helped to keep the battery charged up for the following morning start up.

Malbaby Posted September 29, 2017 Report Share Posted September 29, 2017 I did an alternator/water pump/harmonic balancer conversion similar to this. www.tr-register.com.au/Files/technical/narrowbelt.htm Quote Link to post Share on other sites
Horse Posted October 1, 2017 Report Share Posted October 1, 2017 You asked where to go to get your diff overhauled. I can recommend without reservation Hardy Engineering Transmissions Ltd, 262 Kingston Road, Leatherhead, KT22 7QA, telephone 01372 378927, email: enquiry@hardyengineering.co.uk. I had mine stripped, new bearings, seals and shims fitted for £480 at the beginning of August. Since then I have done about 1000 miles, including 600 in northern Spain and it made not a sound. You can either take the diff in or the whole car and they will remove and refit the diff. I took my diff in and the turnround was one week. One word of warning - if you decide to change the mounting insulators, do not buy rubber ones from Rimmers, as they are too soft. When the car is 2 up, loaded with luggage and full of fuel, they can allow the diff to move so that the prop shaft U/J touches the transmission tunnel if driven vigourously. I am about to go elsewhere to get replacements. Geoff Quote Link to post Share on other sites
