K1 Spring Kit - PeachParts Mercedes-Benz Forum

JamesDean · #1 11-16-2005, 11:24 AM

I will be attempting to install this K1 spring kid in my 722.303 (82-300sd) I found a how- on MBZ.org but lost the link and there arent any pictures. Does anyone have any proceedure / pictures on how to do this properly? Can it be done with jack-stands? or do i need a lift? I will probably be doing this on Saturday.

Thanks Guys..

Kris

PM me your email and I will send you the pictorial directions on the K1. You'll be disappointed how easy it is to do. No need for a lift, jack stands are just fine. And as far as how the springs go back in.. just pay attention to how the old ones come out, and put it back together the same way. I'll send my phone with the email so you can call with any questions.. Since you have to drain the fluid and take the pan off anyway, I'd recommend changing the filter while you're there.. I noticed a good improvement when I did my K1..

You don't even need jackstands other than for more room. I did it without lifting the car at all, just reach under.

what is a k1 spring kit?

a few springs and plunger that replace similar parts in valve body. Increases pressure to K1 piston that frequently improves 2-3 shift flare when caused by worn teflon seals or clutch pack seals.

I just changed the filter not more than 2,000miles ago...

so my flare is caused by worn teflon seals and/or clutch pack seals? The K1 spring itself isnt a cause?

That's what I think. The replacement spring kit is not ABOVE spec. It sounds like it could be just a spring that's lost its resillience.

Is the spring kit K1 also for a 91 300D 2.5 Turbo? I have a slight 2-3 flare under some conditions, particularly when the transmission is cold. Is this something that applies for the transmission in this car as well?

My understanding was that the K1 spring upgrade was intentionally put out by MB to solve the 2-3 fare they commonly saw in the 722.xxx transmissions. Having replaced a couple of them, I can tell you that there is a very noticeable difference. Whether they changed the spec, or the materials, who knows, but the new K1 spring kit is much much stiffer...

If it's an upgrade, that's different. Maybe a worn and weak spring?

Astroman · #12 11-16-2005, 08:06 PM

I can't say for sure, but I believe it is a part they upgraded. It was a known issue...

Is there any point in doing this on a car that you noticed this problem on?

I have a 300TD that I haven't driven with the bowden cable connected. I bought it with a broken cable. I have a replacement cable and a new transmission filter. While I have the transmission apart to replace the filter and cable should I install the updated kit?

Search for transmission adjustments.. There are bowden cable, vacuum regulator, and transmission modulator adjustments you can make that will affect the behaviour of the transmission..
