I have an 82 maxima with the ld28. Pulled the alternator today and the yet to be identified piece that bolts onto the rear shaft (impeller with black rectangular inserts). Well the inserts that fit in the slots fell on the ground and 2 of them fragile puppies broke .I was wondering if anyone knows what im refering to?
They seem to be very very light. The part once again is cylindrical and fits on the back of the alternator shaft.
Knowing how difficult some of the parts are I was feeling doomed when 2 black rectangular wafers just kinda shattered.
What are they and where can i get info to replace them. Certainly Nissan hasn't sold those in ions.
Thanks,
Chris
That thing attached to the alternator's rear shaft!

The vacuum pump rarely fails on its own; most people have problems only when they do what you did. You don't normally take the three screws off that retain the vanes in the housing, but it happens.

I used to have several spares. I might still, but they're three hours and $40 of ferry fare away from where I live now, so you'd have to want one real bad to get it from me

Be aware that the various Nissan diesel alternators have used different length rotors in their associated vacuum pumps, so you can't just swap vac pumps from a Sentra diesel to a Maxima diesel. Click below for more info on that.

okay,sorry it took so long to reply.As it turns out what I really need is the phenolic slats that fit into the pump (barrel,drum or whatever you call it.)A couple of then were a bit broken and the sealing effect is diminished.The car is an auto trans and it downshifts a little more violently when coming to a stop.Also the cruise control works but the constant speed varies by about 5 mph,rolling up and down between 60 and 65 mph when set at 65 mph.
Nissan dealers dont have a listing for the slats and no pumps are available in the dealer network...I guess ordering a sheet of black phenolic and cutting to size will be my only recourse.Only problem is the thicknesses available are not what i need.These slats are very brittle and when i changed out the alternator,two of them dropped to the ground an partially broke.I reinstalled them but am missing a bit of vaccuum.Its not real bad but it should be exactly correct.
