Gday all,
Just wanting to report the days workings on Sherman the German. (See photos attached of today’s inclusions).
As I have come to understand that for now at least, my valve blocks appear to be doing their job correctly and are also not leaking at present, I decided to go ahead and install my newly acquired rubber boots firstly for the rear valve block. I completed this small job with the block still attached as access was great around the area and using the hoist. When it comes time to fit the new boot for the front valve, I imagine I am going to have to remove the valve as access is not as great in the engine bay recess area!.
Took about 20-30 minutes with some gentle persuasion of the boot into the final resting position of the block housing.
The real test was installing the ring that secures the boot over the block housing. That was interesting for sure!.
From there, I finished up in this area by installing a slightly modified w220 chassis vehicle height adjustment rod to the 6.9 (see photos attached), to achieve an equal fit, the w220 rod had to be slightly bent to enable for it to install in the same orientation as the original broken rod. I do not intend for this to be permanent, but rather for $20 off eBay it serves to provide the same function until I can restore the original height rod.
Next, I decided also to vacuum/siphon out the old HPF fluid from the reservoir and perform a few cycles of the suspension (control disc) to purge new hydraulic fluid through the system. All was going well and I had performed 3x siphon, purge and run cycles to have new fluid circulating back and forth through the system.
It is with this action that unfortunately I have come to grief. All was going well for the first 3 purges and I had the fluid returning nice and clean. It would appear as though now, moving the height control disc on the switch unit does not result in any corresponding movement of the ride height….
Previously all was working perfectly (vehicle holding pressure for weeks and the pump was showing strong signs of health as the car would raise in 5 seconds or less every time), the only small leak that I have is from the rear passenger side strut (weeping around the strut), however no noticeable drop in height over extended periods of sitting dormant.
The final step (had all been going well) was to finish the flushing procedure by replacing the small filter (really small sintered filter) and the larger paper filter to complete the job. I have fallen short of this now as this issue has appeared.
Any and all advice would be appreciated in this newly acquired issue.
