When fixing my fuel pump last night I noticed my fanbelt a little loose. There appears to be a bit more than the normal expected play at the pulley
end of the generator, that is to say I can lift the pulley towards the top of the engine bay and take up the slack in the belt. Pulley is tight on
thje shaft so I'm attributing it to the bearing at the end of the genny.
Is there an option to replace a bearing or simply replace the generator?
What about going to an alternator? Pros and cons? I don't really need an alternator or extra power but it seems to be an upgrade a lot of folk do.
Engine is a 1600 type 1.
A bearing is $10 an alternator is $200
The only reason you would replace the gen would be if the bearing housing was damaged, otherwise the bearing replacement and even reco while you're
there would be the most simple.
If you want an alternator, you'll need a kit with stand and backing plates and mods to the wiring are required, all doable but all take time and $$,
and get a good one, many copies are rubbish.

Thanks Matt.
Obviously my preference is to fix what I've got, don't really have a need to go to an alternator, the genny seems to do just fine.
Is it a case of going to a bearing supplier and taking the old one in or is there a specific part I can order up front? Any idea of the part
number/brand?
Can the bearing be changed in the car or does the genny have to come out?
You probably will find that the OD of the bearing has been spinning in the housing causing wear, i have loctited bearings in before to fix this issue, you will need to pull it apart to confirm that is the issue. if it is worn to far you could sorce a end cover in better condition.
The alternators I use are from Vintage Vee Dub. Boris gets a Chinese brand specially made with better bearings. A good price and over the last few
years I've had 100% reliability with the few I've sold/fitted.
I agree with Shayne, pull it apart, checK whats required first. With your description of the amount of play, the housing may be a problem so it would
pay to check first.
By memory the bearings are 6209 but please check. They are common and easily sourced at an auto electrician or bearing shop
You might consider removing the gen (which you definately need to do) and taking the lot to an auto electrician, there are some difficult operations
involved like pulling the bearings and undoing the fan nut depending on what tools you have. Even getting the gennie out can prove to be challenging
for some.
New Bosch alternators still available instaed of Chinese junk.....

I think the bearings are 6203 very common and cheap get the ZZ ones as they are greased and sealed
If that's not the number when you pull the generator apart the number is on end of bearing too easy
Cool thanks for that Mat. I'll give them a buzz to get a price.. Hoopers or CBC are good for bearings and seals too. Even if the bearing has no numbers on them (sometimes the etching wears off) they can match them up for size.
Does anyone sell reco generators? I have limited time to do the job and would prefer a weekend friendly solution. By the time I have it out and ready
to look at, a lot of places would be closed.
Or any ideas on costs to have one reconditioned?
I know there's plenty of Chinese junk gennys out there too.
