They are different and the 'samurai' brakes won't fit. You may be better off sourcing Samurai axles and swapping those in. Bigger parts and a little wider stance. The spring pad location is the only issue.

In looking for brake drums and shoes for my 83. Are they different over the years or will all of the samurai years fit?
I'm also looking for an aftermarket steering damper

I need to replace the steering damper on my 83 sj410 and am wondering if I need to order a OEM one or if anyone has a part number or size for a aftermarket one.

Thanks

Suzuki Samurai (All SJ Platform) 1981-1998 / 83 sj410 wiring diagram

Hello,
My headlights stopped working the other day so I started looking into it and found an absolute mess of a wiring job from the previous owner. Does anyone have a wiring schematic for a 1983 sj410?
I don't see a headlight relay so I'm thinking it's either the switch itself on the steering column or I've got a open wire somewhere
Any help would be greatly appreciated.

On a fuel injected engine, high idle is caused by excessive air flow - the trick is to find where the air is getting in.  It can be the throttle plate open more than it should be, or air leaking into the intake, which is your so called "vacuum leak" - PCV valve & hose, brake booster, literally anything connecting on the manifold side of the throttle plate.  There's also I believe a throttle opener on those motors that holds the throttle plate open for the first 5 seconds or so after startup.

My 91 8 valve has a very high idle (around 2500 rpms) and I can't find any leaks or cracked hoses anywhere. Is there some other component that I should be looking at for a cure ?

Technical Discussion - Performance / Modify / Re: ignition timing after removing vacume line?

Thanks for the reply Eric.
This has tested what I thought I understood about timing.
If timing is too late (retarded) result is easy starting but poor performance and bad milage.
If too early (advanced) poor starting (learned that from kick starting large displacement motorcycles) pinging under load and over heating.
If that's true, how to get the best of bolth worlds?
What might work well on the highway might not be good rock crawling.

Also the PCV valve has now been capped off, might make some differance to the fuel/air mixture.
It is a little more fun to drive now so that's a win.

« Last post by fordem on June 17, 2025, 03:30:56 PM »

The 2004 doesn't have a separate TCM, the TCM function is integrated into the ECM, and the kickdown function is done via a cable.
