Eaton’s TVS – Twin Vortices Series supercharger is the latest range of blowers from Eaton. They are more efficient, produce less heat while having smaller, lighter rotors than Eaton’s earlier roots blowers. Both Jaguar and Range Rover have employed the R1320 and R1900 series superchargers for their 3.0 & 5.0 ranges.
Despite their performance improvements, these superchargers are becoming known for premature wear. Drive couplers are failing, and case bearings are wearing sooner than expected but with a degree of maintenance you can keep your blower working at optimum. On the TVS supercharger rattling at idle is the first indication that your coupler is failing or broken. Continued noise may indicate that a bearing is starting to wear. The important thing is to have a supercharger repaired when you hear early signs of something being wrong – if they are left rattling too long damage can spread from bearing wear, which is curable, to wear of the rotors and/or main casing, which can become bad enough to scrap the supercharger.
Replacing the bearings and oil seals in your supercharger will give it a new lease of life and peace of mind. As long as issues are not ignored and repaired early your supercharger should be serviceable, our Eaton TVS supercharger rebuild kits start at £105 for the snout bearing set.
Please note all prices quoted unless otherwise stated include UK vat at 20%.
The Achilles heel on the Jaguar and Range Rover TVS is the sprung drive coupler, if you have a rattle at idle it could very well be this. The coupler spring wears against the shaft until it breaks and badly wears the shaft as pictured. Our uprated coupler removes the spring from question and works on worn shafts without issue. Simply renewing for a sprung coupler will only end in the same fate. Our uprated oil filled nylon couplers start at just £38.
If you are getting a rumbling or scoring sound from the front of your supercharger or suspect wear for any other reason this can be easily remedied with our TVS snout rebuild kit. At only £105 it is a cost-effective way to have your car back to good health. Our snout rebuild kit includes both inner and outer sealed snout bearings.
In addition, why not take advantage of the removal to invest in a cheap bit of maintenance. A fresh oil change on the TVS is regularly ignored as access is only available when the blower is off, at £24 our oil kit is a very cost effective piece of preventative maintenance.
BUT – if you have any doubt over the condition of the case bearings, it would be advisable to change them as well. The case bearings are prone to premature wear, and you may wish to avoid having to remove and refit the supercharger again in the near future. For the sake of two more bearings first time around consider opting for our Jaguar/Range Rover supercharger rebuild kit!
Our TVS R1320 & R1900 supercharger rebuild kit includes OE components for peace of mind and life of your supercharger. Our kit includes the main components required to refresh and quieten your supercharger back to new with Inner and outer snout bearings, case needle bearings, solid coupler and fresh oil from £270.
If you have had an isolator failure and are unlucky enough to have damage on the drive hub or pins, these can be bought separately from £35.
Our TVS supercharger rebuild kits do not include the pair of bearings and seals situated between the rotors and timing gears of the rotor pack. This is because Eaton rolls the casting onto the bearing outer race, permanently sealing them in, meaning the casing must be fractured to remove those bearings. That said, these are in an oil bath and rarely fail – when rebuilding superchargers, we do not change the rotor pack bearings. If they do fail, some service providers in the US do offer rebuild of the rotor pack, but the Eaton Corporation themselves consider this to be an unreliable and often unsuccessful route to repair – when the rotor pack is worn out or damaged the only dependable solution is a new rotor pack.
If you want to take on rebuild of your Eaton TVS R1320 / R1900 Jaguar or Range Rover rotor pack we can supply you the parts, but caution that it is not a straightforward task.
