hey guys, first post
i have a 1951 sidevalve saloon.
recently the generator armature has given up, so i am in need of a new generator.

is it all possible to swap the pulleys from the sidevalve to a 1000 generator?
how much difference is there in the mounting of the two? I assume i would at least need to shim out the generator a bit to line up the pullys.

You should be able to just swap the pulleys over. Other than the pulleys, the generators are essentially the same.

If you aren't driving in city traffic or at night, the generator isn't needed as long as the battery is already in good nick.
The performance difference is quite surprising too.
(This is assuming your sidevalve doesn't have a water pump)

no, mostly open road till i get back to uni, and even then i shouldnt be sitting in traffic.
tho there is quite a large hill i have to get up, tips for getting up a big hill?
no no water pump, is there much chance il overheat it? it was fairly hot i noticed when the generator gave out (tho i think the idle has been turned up, il give it a tune before i leave)

If it is hilly & you think you'll be travelling slowly under load for a while, then the fan will be needed.

If you're unsure of the motor, then play it safe & fit the other generator so you can run a fan.

i may end up taking an alternative route (albeit alot further, but the hills are alot less serious)

the fan on the generator does seem fairly pathetic, can i get that onto the other generator? (the original dosnt charge at all)

would it be recomended to fit an electric fan?

The fan bolts to the pulley which you'll need to change over anyway due to the SV having a thicker belt.

An electric fan is an option.
For the Tassie trip in 1998, I removed the original fan & fitted 2 thermo fans in front of the radiator.

well everything worked out, after ironing out a few bugs - e.g broken accelerator cable

yes the pulley is just a straight swap, and the mounts are infact the same Very Happy

Excuse the newbish question, but the only thing in a non-water-pump-sidevalve drawing electricity is the coil/sparkplugs, right?

That's why it's okay to not have a generator so long as the battery is in good nick?

Of course I imagine it would pay to charge it up when you got home Yellow Sedan

Also, how does city traffic make a difference?

What a wonderful line. "It's a sidevalve, it's always at full throttle !!" would make an awesome bumper sticker! Yellow Sedan

id imagine that with a good battery at full charge, you could probably get a fair distance. even further with a crank start

City traffic = stop/start = little or no airflow from moving.

If the fan belt is off, the fan on the generator isn't pulling air through the radiator.

Days, weeks even if no lights are used.

expecially so with the sidevalve "fan", yet it seems to hold up to the traffic here, not that i make a point of going out when its heavy
