Replacable Bearings/bushes In 280 Distributor?

[aircobra]

i think i worked why a set of standard points would not fit in my distributor - it is because of the play in the shaft

has anyone replaced the bushes /bearings in one of these? i can't find anything on the net

[600Z]

I have but I turned them up in my lathe out of bronze and worked no problem.

[aircobra]

so they're just plain bushes originally, not bearings? does the shaft itself wear out? how did you press them out?

[600Z]

Just a plain bush, like a spigot bush in the end of your crankshaft.

 

You would be able to tap it out from the other end using a long pin punch or a steel rod I'd think but I turned mine out as at that time I didn't realise it was replaceable. The shaft was shiny but no real wear.

 

Do you specifically want to stay with points?

[600Z]

Actually i remember now the one I did the bush for was what looked like a steel bush, sorry was a while ago.

[aircobra]

not fussed on the mech. points, that's what there at the moment. are you saying that if i convert to el.points, shaft wear won;t cause problems?

[aircobra]

is there option for me to buy this and replace electronic bits with my existing points

the guy doesn't say where go the replacements from ;-(

[600Z]

Shaft wear will always cause problems.

That's a pretty good write up on rebuilding one but yes a shame he didn't say where he got the parts from.

 

I have seen in other posts where guys but complete new aftermarket 280zx units which might be the way to go in the long run.

 

Flick through some of the old posts and I'm sure you will come across them as you wouldn't be the only one that's been in this situation.

$60 and problem solved?

If any replacement ignition system relies on the distributor shaft for it's operation then that shaft must be true and operate within wear limits.

ok, here's the deal

1. a couple of local rebuilders,such as performance ignition want around $330 to 350 to rebuild the distri. that means machining the shaft and pressing in new bushes

2. can get a reco'd 280z electronic off ebay( i know there are a couple of threads on this ). about $180 shipped

4. same, but $130 non-electronic

what's the deal with dual points?

5. can get one from someone on the forum or the wreckers ( although all of these will be 30 years old also)

6. this one from what looks like a L26

but i'm not sure that the curve eg the mech.advance and the vacuum spring is setup the same as Z, given that it comes off a fat, lazy sedan. same cost as above, but brand new (although chinese made)

 

any suggestions?

Perhaps this topic is still relevant. Just had my 280zx distributor reconditioned by Performance ignition https://performanceignition.com.au/ Cost $380 with a new cap. The main problem with the Dizzy was the vacuum and the mechanical advances (it is 41 years old). Performance ignition were great. Quick turnaround and the Dizzy now looks and operates brilliantly. A very noticeable performance improvement. Well worth the investment.
