HelloCustomer
Could you describe the reasons for the replacement of clutch boosters? What are the symptoms? What is the VIN of your truck and the part number of the last cluch booster you have installed?
Regards,
Stan
The problem we have is that the servo failing prematurely. We earlier thought that the quality of the replacement parts are inferior. But the local Benz delearship also confirms that the parts are genuine or good OE. The failure is on the part of the Hydraulic where the seal gives in within two months after fitment. We have broken open the last failed Chassis No:WDB9423110001 do not have the part number at the moment.
Sorry for the delay,
Could you recheck the VIN, because th number must be 17 character long.
There is one workshop information i suggest to try. Here it is:
Poor metering of clutch, clutch does not separate
Clutch booster does not operate correctly (piston has excessive resistance / is seized) or is leaking
Fit repair parts kit for repairing the clutch booster.
IMPORTANT: Select the repair kit depending on the hydraulic medium:
- either for DOT 4 (brake fluid), WITHOUT sales code IY2
- or for hydraulic fluid as per sheet 345.0 (Pentosin CH 11 S), sales code IY2, green cover
On vehicles with transmission capable of fording (code G39) the cover plate on the clutch booster must be sealed with silicone (e.g. A(NNN) NNN-NNNN10).
Please recheck the VIN, then i will be able to look more closely into this.
Best Regards,
Thank you for the response. But I believe my question remains unanswered as I do not replace kits but complete servo unit. The problem is that we have regular failures of the new servos even when we fit genuine quality. The failure is on the hydraulic seal that fits on the hydraulic piston. The seal just wears out than raptures.
Such a fault is not a known failure on these trucks. That is why i recommend to repair the servo according to factory info as a first step. It might be possible that the repair kit is of better quality.
Another possibility is that replacement procedures are not adhered to. I can provide you with these if neccesary.
As i wrote earlier, it would be great to recieve the full VIN of the truck, because i cannot see the transmission/clutch version without it.
