Thread: 3200 Air Compressor

  1. #1
    Evening all!

    So on going to get my air con regassed today it seems my compressors seals have gone and was advised I would need to replace. I was given a price for a replacement (from an Alfa 166 - code 14-1121). I also had a quick online search and found reference made to a Sanden SD1 V16 as suitable replacement:

    http://www.maseratiforum.co.uk/3200G...m_23172/tm.htm

    This also mentions a company in Birmingham who supplies replacements/refurbishes them. Anyone on here used them or others?

    As to fitting the manual suggests it is quite straightforward (wish I had done it when changing the timing belt earlier this year!) but anyone got any pointers on it? How much do I have to remove to get to it? Possible from below?

    As always, any help gratefully received before I start poking around!

    This one will fit, but you'll need to open up the rear mounting hole to fit the spacer. Cheapest I found. It comes out from below and is very tight for space. You'll need to strip off hoses to the intercooler and remove brake duct. The top bolt is accessible from above and the bottom one is a nut and bolt.

    Forgot to add - drain the oil from the compressor and refill with PAG (preferably with a dye in it) and lube all of the O rings with PAG oil when refitting.

    Thanks! Had another closer look last night and looks doable as you suggest - just the top bolt being the pain. Just to clarify before I start fiddling:

    "you'll need to open up the rear mounting hole to fit the spacer" - can you explain this a little more or is it obvious when you take it off?

    Regards

    There's a top hat shaped spacer that fits in the rear bolt hole. Said hole is too small and needs to be drilled out. Blowed if I can remember what size though, sort. It's pretty self explanatory when you have int on the bench in front of you. Think of it as a sliding spacer.

    The top bolt is easy once you get the induction pipes off if you're using an hex socket with a short extension (or long hex socket). Hook a ring spanner over the nut on the rear of the bottom bolt and it's easy enough, if a little fiddly. The biggest issue you'll have is getting the single allen bolt on undone on the pipe connection on the pump. The head is very shallow and will round off quite easily with a poor fitting hex socket/allen key. Best to get a new bolt beforehand and be prepared to struggle a bit with the old one. You can split one of the pipes from just above the pump and the other disconnects from the dryer/filter (same as Alfa 155, just so you know) which will also need to be replaced. That's a pain in the backside to get to, as it's headlamp unit out/ indicator lamp unit out/offside air filter assembly out to get to and then it'll fit through the headlamp hole once removed from the mounting bracket.

    Ahh - thanks for that - think I have it now. Just need to prepare for the scrapped knuckles now...

    All out without too much swearing! Just before I start getting it all together to put in, any particular PAG oil as it seems you can get a few grades? Thanks again for any help - hopefully this thread will be useful to others who have the same job to do in the future.

    135ml of PAG46 I think from memory, but best to check with A/C guy that's doing the regas, he should be able to find the correct information.

    Just to update for others doing this - the dryer filer unit is the same as an Alfa V6/GTA one (as is the compressor itself) but is much cheaper than the Maserati branded one.

    Thanks again Trev for the help!
