Rebuilding struts
Any of you old school dudes ever do this? There's a whole section in my RX-4 shop manual on rebuilding the front struts.
I'm wondering if you could make them damp more by pouring in thicker oil? Or maybe machine a new valve with a smaller hole? Where would one get this mysterious damper oil that they show in the manual? thanks |
What weight oil does it say to use?
|
It doesn't say what weight oil...It says "Fill with shock absorber fluid. Capacity of reservoir should be exactly 270cc."
|
270cc each? OK...
I've heard to use motorcycle shock oil, but i guess i'm gonna have to experiment with what weight to use! |
I used to build radio controlled cars (the expensive "hobby-quality" kind) and the more sophisticated ones had oil-filled shocks which you could tune by rebuilding them with different valving or thicker/lighter oil. So that's where I got the idea.
I wonder how similiar my RX-4 struts are to the 1st gen. RX-7 ones? |
Just buy gas shock inserts that will drop right in and you do not have to mess with the oil and you get better damping. Mrmasda

Those cost a lot of money and they're not tuneable and they're hard to find. heck it's hard enough to find performance struts for '79-80 RX-7s!
Anyway, on a Capri list I read that you can't go too thick because then the high-speed blowoff would actuate too early and the damping would actually get softer. That site said 20wt oil was at the very high end of what should be used - 5 to 15wt being the area you should experiment with. But, that's for a Capri, dunno how Mazda did things vs. Ford of Germany. At any rate, one other thing I learned is that if you experiment with non-shock oils, only use synthetic oil, because it's less apt to change viscosity with heat. |
