Removing the 24V generator from a FFR. Alternator out first?

[spudboy]

I have pulled all the 24v stuff out of my FFR 1990 Perentie, but I can't work out how to get the 24V generator out from the engine bay. I've got the idler/tensioner wheel and the two belts off.

The only thought I have is to take off the 12V alternator and see if it squeezes out that way (i.e. pulling out in an upwards/vertical direction).

There is a whole vacuum assembly on the back of the 12V alternator though - I want to remove that from the back of the alternator so I don't have to "un-plumb" so many things. If I unscrew the 3 bolts holding onto the alternator, is it easy to get it back on again?

Anyone already done this and can offer some guidance?

Thanks

G'day David,

take a look at this tute -

24v generator (http://remlr.com/forum/index.php'topic=1587.0)

Also the EMEIs indicate that the vacuum lines and the oil feed to the 12v alternator should be disconnected and plugged and that the B terminal wire (nut & washer) and the field plug should be disconnected prior to removal of the 12v alternator.

Thanks for that link.

Don't like the sign off line - "Its a pig of a job that took about 4 hours".... :(

Any thoughts about disconnecting the vacuum pump from the back of the 12V alternator?

re the 12v alternator vacuum pump - take a look at my last para above...




anyhow I hope you can enlarge these enough to read them :)

note the remarks about the pre-oil of the oil fees line on replacement

With these instructions and the tutorial it surely couldn't take 4 hours - but let us know how you get on & how your back is when you're done. :)

Note those remarks about supporting the 28v gen as you undo the support brackets.

Might be a good idea to have some help/assistance when lifting it out

Whether to disconnect the vacuum pump itself ? The instruction is to disconnect the "plumbing".

Disconnecting the vacuum pump itself instead could still leave it in the way.

You can get it out without removing the 12V alternator - you will need to loosen the 12V alternator and push it toward the engine as far as it will go, then remove the oil feed at the back of the alternator. The just undo the straps and the two big bolts holding the 24v assembly in and Jenga it out - took about 20 mins. Don't forget to retension and reconnect the 12V unit!

Thanks for that Dingsy - I was wondering if there were any tricks to getting the vacuum pump off, but it sounds not.

I'll give it a go later today and report back on my success or failure!

Edit : I've just re-read your answer, and you seem to be saying to take the oil feed off, not the whole vacuum pump....

Hey Spudboy, I wouldn't remove the vac pump if I were you. they are a pain to get back together without leaking as they have an o ring under the flat plate which is a pain to get back in place unless the alternator is sitting nose down on the pulley. Just undo the 3 hoses and remove the whole alternator and it's out of the way completely then. Don't get rid of the 28V alternator bracket and adjuster jockey setup - the a/c compressor will fit straight on there if you want to add it later.

mine generator took a "leisurely hour" to remove

[spudboy]

I would agree with the 1 hour observation. Not sure how the guy from an earlier post spent 4 hours pulling it out!
