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 maybe signs that a bearing is starting to wear. The important thing is to have them 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 services start at £195 for a snout rebuilt (to a loose snout).
Please note all quoted prices unless otherwise stated include UK vat at 20%.
TVS UPRATED COUPLER
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 and our replacement service from £96 + Carriage.
JAGUAR TVS R1320 & R1900 SNOUT REBUILD
If you suspect a snout bearing needs replacing we can service your TVS snout from just £195 plus return shipping. A cost-effective way to have your car back to good health. Our TVS snout rebuild service includes strip & rebuild with new front and rear snout bearings, plus a good clean and prep for immediate use!
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, so may wish to consider our TVS supercharger rebuild service.
JAGUAR/RANGE ROVER SUPERCHARGER REBUILD
Our TVS supercharger rebuild service includes OE components for peace of mind and life of your supercharger. We inspect the supercharger, check tolerances and advise if required, we then deep clean and replace all the main components needed to bring a new lease of life to your blower. This service starts from £567 plus return shipping.
ROTOR PACK BEARINGS & SEALS
Our TVS supercharger rebuild services 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 attempt to rebuild your Eaton TVS R1320 / R1900 Jaguar or Range Rover rotor pack we can supply you the parts, but caution that it is not always successful
