Track Bar/Broken Shock Bolt

The standard replacement bolt (as recommended by the factory) is a:
M16 x 1.5 X 290mm
....although you could go for an imperial equivalent, if you couldn't get the metric size.

Peter, Hi manual #907.1.70.357.4 On Page 34 states vers. 11 #12 M16*1,5 DIN 985-8 IS this the same? Thanks. What does DIN 985-8 stand for?

To clarify I have never been able to under stand how to translate DIN.

Ahh, Erik you pointed out my mistake, sorry about that....I gave you the bolt length for a 712! .... I forgot all about 710's

710's require a:
M16 X 1.5 X 395mm

As regards the number you quoted..... INTERESTING!
It shows you that a 710 "bolt" is actually, a stud and nut (the assembly of which is Fig 22, Fig 12 is just the nut), as opposed to a 712 "bolt" which is actually a manufactured bolt.
You live and learn all the time!

BTW: Don't worry about the DIN 985-8 that's just the component compliance standard!
(DIN = Deutsches Institut für Normung)
I daresay that if you looked in the spare parts manual for a piece of specialist USA built machinery that they would say the bolts comply with American Standards/ANSI xxxx requirement.

Hi Guys,

We have updated some of the pics on our site with some of the testing that we did. We spent quite a bit of time with Doetsch engineering to determine if their is any issue in regards to the HV1's. The non-rebuildables are a non-issue as their lengths are fine.

Doetsch DID change the manufacture of the HV1 in early 2008 by changing out the end cap to one that would accept a remote reservoir, and adding an additional external bumpstop. This had the effect of lengthening the shock body by .5", and decreasing the fully collapsed length by the .5" + the bumpstop compressed length.

We have spent two days working on different configurations of the Pinz drivetrain and are pretty confident that the minimum required compression that we need for a 712 is 13.75" (You can see the lengths we went to compress the suspension of both 710's and 712's on our site.)

The HV1 with the Bumpstop removed measures just shy of 13.75" As the Pinzgauer already has a robust rubber bumpstop in it's suspension, the added stop that Doetsch has on the HV1 is not needed. (As per Doetsch)

After discussing in depth with Doetsch engineering and our own suspension measurements, we recommend the following:

Doetsch Non-Rebuildable - Applicable to both the 710 and 712 with No Modifications required.

Doetsch HV1 Rebuildable

710 with Light to Moderate off-roading - No Modifications Required.

710 with Heavy fully loaded articulation - Remove the rubber bumpstop.

712 with Light off-roading - No Modifications Required.

712 with Moderate to Heavy off-roading - Remove the rubber bumpstop.

712 with Extreme off-roading with loads - Remove the rubber bumpstop, replace the remote reservoir endcap, with the non-reservoir endcap. (This is something you would coordinate with EI, or Doetsch if you purchased direct.)

Hope this helps.

Cheers,

Scott Ingham

Erik,
The bolt is 12 inches long and 5/8ths diameter. There is an inch of thread showing so, you could go with an 11 or 11 1/2 inch one. I got it from McMaster-Carr. - Buzz
