Probably just as easy to buy another 2nd hand one in good working order, some of em go for under $100.
Presuming the electronics are in working order, there is a bearing you can replace and apart from dusting out thats about it as far as "reconditioning" is concerned. L8r E
What im wanting to do is recondition a spare cas that i have. By recondition i meen replace all electrical components and bearings with brand new items
The only parts in the CAS you can replace are the bearings. The electronics and opto sensors are sealed units. Check out the 360 tiny slots at the edge of the disk.
The optical CAS units are replaceable. A lot of mysterious missfirng a rough running issues can be traced back to dust and dirt caught in the optical "eye" slits. The slots around the outside of the disc are the 2 Deg. synch timer slots and the ECU uses these slots as a timing reference against both the position of the 6 trigger slots and the duration of the trigger slots to decide which cylinder is firing when quickly. Other systems that use, say a 60-2 wheel and a single reluctor or hall Effect trigger or perhaps an optical system like a Pulsar Turbo which has the single large trigger slot and the synch timer slots, will sometimes have to crank a larger number of periods before the CAS "sees" its home position and then knows how to sequence the firing/triggering order in a fully sequential system. The ECU is instructed to ignore a minimum of 3 trigger cycles in the case of a 4 cyl or 5 trigger cycles in a 6 cylinder before the ecu will trigger. I digress........ Sometimes oil mist,due to a rooted PCV system which causes the crankcase to pressurise and blow past the shaft bearing seals, can make its way into the cas and get into the slots as well as CAS's "eyes", confusing the ECU and result in some very strange running problems from minor popping thru to major faults. The optical pickup eye slits are very fine and I doubt they can be cleaned without disassembling the eyes from the rest of the CAS assembly which requires their wires to be desoldered off the circuit board.

They look like they can be replaced but with what? As far as I know they are not available. Although places like RS Components sell some optical sensors http://australia.rs-online.com/web/
Hers a couple of Tridon numbers. TCAS10 Interchanges with RSB-04 TCAS17 Interchanges with J917 I would say the 2 numbers are early Mitsubishi up to 09/93 and latter Hitachi units, although i though the plugs were different but they look the same in the pictures, any way you know to look out for the difference. The module inside the CAS is supposed to be marked, one module has a higher optical sensor housing then the other and slightly different mount points. N*Power has the TCAS10 Tridon part for $150, I think its the wrong one for most of us, but they should be able to get the TCAS17 on request. http://www.nahux.com/NPOWER/product.php?part_no=TCAS10 TCAS10 TCAS17 Picture courtesy of MickW http://www.aus300zx.com/forum/showthread.php?t=311414 I have not tried these and do not know if they are any good, if you were to try this and replace bearings etc, you would want to have a good look at the housing seals as TSK said dust in here will not be a good thing, you want near clean room cleanliness when assembling.
