Dynamo to Alternator Bedford RL

[Bedfordrl]

After putting up with the dynamo struggling on long wet runs home at night and now after replacing the dynamo with one from an autojumble that is u/s, i want to change to an alternator.

Has anyone else done this and if so how did you get over the problem with the belt size in the alternator pulley and as the dynamo is longer what did you do to make it fit as well as the wiring changes?.

Thanks

Hi Glen,

 

I am having to cast my mind back a long time here, but we used to rebuild 300 petrol engines in REME wksps in 70/80 period and had numerous variations depending on the vehicle it was to be built for. I seem to think those destined for the later coaches (SB3 chassis model) might have had alternators. The 330 diesel engine as in TK etc. could offer up parts such as crank and w/pump pulleys. Hope this is of help.

The Bosch alternator fitted to the Mk4 Escort has a split pulley, you can use a spacer to get the correct width for the belt. I did this on my GMC and it worked perfectly. Get one from the scrappy, this alternator is very durable, should last for years.

My dad converted his champ to an alternator, used a bus alternator if I remember rightly.

He got a local car electrition to wire it up for him.

Go to your local car electrical installer and they will advise you of the best way to do it.

I'll have LIGHTS. :yay:

Get one of the machine-sensed Lucas ACR series, 15, 16 and 17ACR, all will do the basics with no hassle and mostly will fit easily in place of a standard Lucas or CAV dynamo without too much mechanical work.

 

You'll have to rewire the warning light connection to the WL or W terminal on the alternator, it would have been on the RB310 regulator. make sure it is fitted as the light willnae work otherwise....

 

There's a selection of CAV stuff on our websites, and specifically there is a good bit on alternator systems down on the bottom right of the menu.

I've got the ACR data sheets here, not had time to scan them (along with a huge amount of other stuff!)

 

The original conversion was the 11AC, with three separate external relays, the ACR does it all in the one machine.

Glen,

 

Be aware that the RL is +Positive Earth, if I recollect.
