The alternator was already fitted when I purchased the van and it was sensible to retain what is considered to be the best form of generation in any vehicle,why take a retrograde step and revert back to a dynamo? Most of our DAFs are used for small journeys and rarely as daily transport.My 33 Pick-up has had an alternator fitted for 12years and even when it was not used for over a year it started easily and the battery fully charged very quickly, this wouldn't have been so if it had still got a dynamo.

I havent forgotten the circuit diagram, just got to get the old scanner working again!! I could not find your LRA743 anywhere. Only LRA100 or similar. Pictures of yours would be helpful! Now it is my turn to find someone who can handle Daf 3 hole, no centre hole wheels! One has a very slow leak somewhere around the rim.

Quite interesting,when the wheels and new tyres were dropped off yesterday evening I asked if the wheels still needed the amount of balance weights that they had on them,the reply was that they balanced easily with the new tyres and only one small weight on each.They had not been balanced properly in the past.There were 6 wheels with the van one of which had a brand new tyre but at least 7 weights in one area of the wheel.I used that wheel to stand the van on while the other 5 were re-shod,when I jacked that corner up the weights were at the top,as soon as the wheel lifted off the ramp bed the weighted area swung at speed to the bottom. If that wheel had been on the front and driven the van would have been un-drivable. I think that proved how important it is to find a fitting shop with the ability to balance DAF wheels with no centre hole. Has anyone thought of publishing a list of DAF friendly garages/businesses in the UK? The BSA Bantam Ownwers Club publish a Good Blokes Guide.Perhaps if folks sent into Richard, companies who give good "DAF" service, they could be listed in the Mag? Just a thought.

The alternator my motor factor supplied was too bulky,so I finished up ordering the one on ebay which is smaller and produces less power.It's a Lucas pattern and to remind anyone purchasing an alternator make sure you order one for fitment on the left hand side of the engine. Be prepared for a lot of time being spent in making a bracket to fit the alternator,there is a limit to where it can be placed,especially to avoid the drive belt rubbing on the oil cooler pipe. I have spent a lot of time making up brackets,to get it in the correct position. The Pick-up had an alternator fitted when I bought it, so having to fabricate a bracket is being a pain, but I am almost there. I will need a different drive belt once it is fitted.Unfortunately the Pick -up is some distance from home so I couldn't copy the bracket on it.

The alternator ordered off ebay is fitted and working fine.It took quite a while and many alterations to the bracket to mount it in the correct place as there is only a very small place to bracket and fit. Can I thank everyone for their comments and advice; you all certainly gave me food for thought and without the help I would have spent even longer getting it up and running.

Your explanation suggests one of two explanations: The belt might not have been tight enough, causing it to partially slip and in doing so become hot and then melt, although given your experience with cars, and Dafs in particular, I think this unlikely. Another explanation might be a failure in the alternator bearings. To check things out check if the alternator pulley turns easily and smoothly and doesn't feel "rough". Something else to consider is that Daf 33s were not supplied with alternators as original equipment, so any alternator fitted has to line up exactly as the dynamo would. The pulleys need to be precisely in line, so check this. In addition, most alternators are shorter than dynamos, so the bolts securing it to the engine block must prevent the alternator "twisting" on its mountings and thus mis-aligning the pulleys that appear lined up to the naked eye. The use of a decent engineer's straight edge is useful here. I KNOW this will sound stupid, but you have removed the regulator from the circuitry, haven't you....? More advice once if you need it! As a rule, the breakage of the generator belt occurs due to its deterioration. While working.If you find at least one of these signs, then do not pull with a replacement, the consequences will not be long in coming. The fact that not everything is in order with the drive can be signaled by a characteristic whistle. This usually occurs in wet weather. It happens that he disappears during movement, but sometimes it doesn’t. This is due to loosened belt tension. Sometimes it is enough with the help of tensioning mechanisms to tighten the belt stronger, but, as a rule, its replacement is required.
