Do the same for all three rivets and average the results. Set up your dial gauge so it is sitting on one of the three rivets on the clutch as shown below.Īctivate the clutch with the 12V battery and measure the amount of movement on the SECOND activation (well NOT the first, the clutch has to seat properly first). Reinstall the clutch and the washers and tighten the centre bolt (not too tight, just nip it up). Now we set the clearances for the clutch. Stick the circlip back on to retain the pulley. Ok, once the new bearing is in firmly to the bottom. Īlso, be sure to put the small ring back in the right way up too. Be sure to hit it in evenly all around the edges only so it doesn't skew and jam up (only hit the edges so as not to shock load the balls and dent the races in the bearing). Now grab the new bearing and use the old one as a drift to tap the new one in. Give the pulley a good clean with degreaser etc and a soft brush. I used a socket that fit into the bearing when placed upside down (bolt side of the socket facing up). Give it a few good whacks and it'll drop out. Just put the pulley over the hole on the anvil or brake drum etc and put a socket on the bearing from the top. Once the pulley is removed, you need to pull the bearing out.ĭon't stuff around with pullers etc. This electromagnet is also the same as the late SC12 and Previa SC14 superchargers. Remove the circlip, then the magnet and give it all a good clean and reinstall. When you remove the pulley, you will see the electromagnet. Remove the circlip with a pair of circlip pliers and pull the pulley off. (pending speed ratings on the compressor.) Theoretically, you could use an old pulley from the above superchargers to further increase the speed of the compressor for a higher cooling capacity. Interestingly, these pulleys will directly fit the late SC12 and SC14 (as fitted to the Previa) superchargers, although they are larger in diameter. We don't want to reduce the cooling capacity at all, so we will reuse the Sera pulley. This is to spin the compressor faster on the Sera unit to provide greater cooling due to the large thermal load on the cabin from all the glass. You will notice the pulley on the Starlet compressor is much larger than the Sera pulley. There will be one or two there, Keep all the ones from the compressors you pull down for parts as we'll need them to set the correct clearances on reassembly. When you take the clutch off, be careful not to loose the washers on the shaft. This is no good, so I replaced it with the clutch from the Starlet compressor. The one from this Sera had years of oil leak on it so it ended up slipping and heating the clutch to the point that the metal turned blue from heat hardening. Once the pulley has been removed, clean it with degreaser to remove any grease or oil. The clutch has a larger hole with an M8 thread in it, so when you screw it in, it bottoms out on the shaft (the bolt you just removed is smaller) and lifts the clutch out. Grab your M8 bolt and screw it into the hole. Do the same with your compressor.įirst thing is to remove the clutch from the pulley.Īpply 12V to the electromagnet to engage it, this will allow you to grab the pulley to hold it still while you undo the 10mm nut in the center of the pulley. Be sure to put some tape or something over the piping in your car to stop dirt and moisture getting in. I'll assume you have the compressor out of the car ready to go. 30BGS10DST2 (30mm x 52mm x 22mm) (this part supercedes the original bearing part number) AUD$42.90 as of, just be sure to check your bearing part number though. Replacement compressor from a Starlet or Sera (if required)
Something with a hole in to use as an anvil (an old drum from a rear brake makes an excellent all purpose anvil) The AC guy commented that it's the first he's seen of that type that was stuffed in years.īasically, if it makes no noises from the compressor itself and your AC is getting cold, the compressor is fine. Ours was buzzing, which was apparently a slightly stuffed valve inside, but it still worked. The good thing about these compressors is they rarely die. You can't actually rebuild the compressor itself as it's a 'sealed' unit, and it's WAY cheaper just to get a good one from the wrecker and use it if yours is stuffed. It's a really easy job and is able to be completed with basic hand tools.
#Car ac compressor rebuild near me update#
I'll update this with the Corolla bearing part number when I do my Corollas compressor (it'll probably be the same). The actual parts will be slightly different for other compressors, but the procedure is pretty much the same. I've just successfully rebuilt an air con compressor for my brothers Sera, so I thought I would share how it's done.
