End of Warranty and Terms of Sale



Special Turbocharger Warranty and Terms of Sale

All new Rothenbacher Turbochargers carry a TWO YEAR warranty from Rothenbacher Engineering. If the turbine wheel has been clipped, the turbo warranty falls to who ever clipped it. Our turbos are built and warranted by us.  Whether or not a failed turbo is repaired or replaced under warranty is up to our company’s discretion. All failed turbos we have ever seen have obvious damage from lack of lubrication, contamination in the oil or the turbo ingesting something. Many failures are blamed on "hot shut down". Unfortunately, with the way turbos are designed, there are lots of things manufacturers and rebuilders can point to, to deny any responsibility. 

Please note: If one item pertaining to the turbo is not functioning properly, the entire unit must be sent back, unless we give direct written instructions to do otherwise.

Customers are responsible for ensuring that parts installed in their vehicle are used properly and are designed for the operating system installed. Customers are also responsible for maintaining their vehicles. Under no circumstances does RE ever pay installation expenses. If a part that RE sells is claimed to be defective or incompatible, RE does not cover installation or removal expenses of that part. If a part that RE sells is claimed to have caused damages to other parts in a customer's car, RE is not responsible for those damages.

RE is not responsible for damages under any circumstance or condition, even if the part or parts were installed by a professional or certified mechanic. We strongly recommend all consumers have a professional installer to install the parts. Vehicle protection is your responsibility. The Buyer shall not be entitled to recover from RE any consequential damages, damages to property, damages for loss of use, loss of time, loss of profit or income, or any other incidental damages. The Buyer shall not be entitled to recover consequential damages caused by a failure of a RE part. If the turbo is repairable under warranty, we will do our best to ensure that a replacement will be sent out as soon as possible.

Warranty Rebuttal:                                                          

Your turbo will NOT be covered under warranty by Rothenbacher Engineering if:                            

1) Shipping damage. Inspect your turbo the day you get it. That is the time to report any damage from shipping so that we can file a claim with the carrier. Turbos often sit around for weeks or months before they get installed. During this time, anything can happen to them that is not under our or your control. Everyone that touches your turbo when you are showing it off has a chance to damage it. You must report any fin or actuator damage immediately

2) Any damage to either the compressor wheel or the turbine wheel. Bent fins will be caused by either the turbo ingesting something or serious compressor surge. 

3) There are heat marks on the shaft. Lack of oil will turn the shaft blue and make score marks in it. If there is a blue shaft we will not cover it.

4) Damage from "hot shut down". This will appear as a lack of lubrication. If you are under full boost, the turbo will be spinning close to 100,000 rpm. If the motor is shut down or stalls under full throttle and high boost, the turbo is still spinning at extremely high speed with no oil pressure. Also shutting down a glowing hot turbo with out allowing time for it to cool down will cause coking (excess carbon deposits) that will block oil supply. 

5) A new oil supply line is not used. You must use a new oil supply line. If you do have a problem, send a copy of your oil supply line receipt back with the turbo.

 


Common New Turbo Install Problems:

Smoke:
You were doing some grinding or porting near the motor with the turbo removed. You blocked off the turbo oil drain pipe with a piece of tape. You forget to take the piece of tape off and install the turbo. Start it up and smokes instantly. The oil flow into the turbo has no where to go and gets pumped out the bearing seals. If your turbo does this, check the oil drain for blockage, remove it and start it up again. The turbo will be fine; it will take a few minutes of driving to burn out all the oil from the exhaust system. Also a plugged up crank case vent will cause excessive pressure to build up in the crankcase. This prevents the oil from draining out of the turbo and blows the excess oil out through the turbo seals. 

Problems with the Shaft:
Our turbos use a sleeve type bearing. The shaft spins inside a bronze sleeve. The sleeve also spins inside an outer housing. This way; if the turbo is spinning at 80,000 RPM, there is a 40,000 RPM speed differential between the shaft and sleeve, and a 40,000 RPM speed differential between the sleeve and the outer housing. This is what allows the insanely high RPMs common in a turbo. There is a gap between the shaft and sleeve and a gap between the sleeve and housing. These two gaps combined allow the compressor wheel tip to move side to side in what may look like an alarming amount. This is normal. As long as the wheel is not touching the housing, you are fine. There should be no play axially (in and out) with the compressor wheel and shaft. 

Waste Gate Actuator Damage:
The wastegate actuator can become damaged. We do our best to carefully package the turbo assemblies but sometimes one of our shipping carriers can decide to be careless with your package. The actuator can get slightly bent or crushed. Check that the bottom surfaces are not crushed in at all. If it does get, it can be easily bent back before installing the turbo. Just pry it back until all surfaces are at a 90 degree angle. There should be a slight pull on the wastegate arm when the actuator is connected to the arm. Be sure the small cotter pin is in place. 

New Head?:
If you keep going through turbos after a recent valve job or other head work, your problem is probably related to lots of left over junk in the oil supply galleys in the head. If your machine shop uses abrasives when cleaning the head, they had better take out the oil galley plugs and clean the head for days. Certain cars get their oil supply from these oil galleys and when the junk flows into the turbo, it kills the bearings instantly.

Plugged-up Internal Oil Passages
Over use of thread sealer or silicone thread sealants can get inside the turbo cartridge and block small oil passages. This kills the turbo bearings from lack of oil. 

Compressor Wheel Damage
When re-installing the turbo be sure that you take out any rags or anything else you used to block off any inlets or intercooler hoses.

Old turbo has gone bad:
Think about what could have caused your old turbo to die. If it was death by old age (100K miles +) or you were over boosting then no worries. But if you killed a fairly new turbo for no apparent reason, think about what could have been the cause of the turbo's failure. If you simply bolt on a new turbo with out fixing the problem, do not expect your new turbo to live long either.
