RV8 back axle reconditioning service
This note is reproduced from the RV8 Spares Update as a
sequel to RV8 Workshop Note 155 from Lowell Smith describing how he
got a noisy back axle repaired. It describes the back axle reconditioning
service provided by Clive Wheatley, who adds a footnote. (Oct
Wheatley launched an RV8 back axle reconditioning service earlier
in 2002 at a time when several RV8s have been experiencing noisy back
axles and showing signs of wear. The service is based on complete
reconditioning of members' own back axles, including both the crown
wheel and pinion and limited slip differential. An exchange service
is not available.
back axle was a one-off unit for the RV8 whereas the LSD was not
so. The availability of crown wheel and pinion parts have been a concern
whereas the LSD components less so. Recently Clive found the original
supplier for both the crown wheel and pinion and the LSD for the RV8.
A new batch of crown wheel and pinions has bee produced and has been
available from the end of July 2002. So Clive has solved a potential
difficulty which might have become an increasing concern for RV8 enthusiasts
with back axles needing repair. Clive says "there are twelve
gears in the RV8 LSD so it has always been a little noisy rather than
the other type of LSD with a clutch. Recently I have had two RV8s
needing treatment on the back axles - the most recent was a 70,000
mile RV8 with a noisy back axle so I thought it was time to do something
as many cars are approaching or beyond that mileage".
In terms of cost,
Clive indicates "it will depend on the amount of reconditioning
work and parts that are found to be necessary, but as a guide
reconditioning is likely to be in the range £500 to £1,000
including labour and materials plus VAT for the reconditioned back
axle". On top of this you will need to add the costs of removing
the back axle, freight both ways and reinstallation. As a guide, the
price for a new RV8 back axle from MG Rover's spare parts supplier
is reported to be around £2,000 including VAT so a complete
reconditioning service is a worthwhile option for an RV8 enthusiast!
Footnote: Clive Wheatley indicates the new crown wheel and pinions
are available from stock at £275.00 plus VAT and carriage. Since
announcing his back axle refurbishment service earlier this year,
Clive reports he has done three RV8s, including that of Lowell Smith
described in the recent workshop note, one of which had 95,000 miles
on the clock. That unit in that high mileage RV8 was not too bad but
Clive urges members to check the oil levels in their RV8 back axle.
Clive generally recommends replacing the CWP if the back axle is being
refurbished although there may not appear to be much wear on the CWP.
The new batch CWPs is well up to the job of handling the RV8's 190bhp
power output as the CWP is also used in another sports car generating
400bhp and in a van. Clive has noticed that one item which is not
mentioned on the MG Rover parts fiche is the back plate and this is
an item which may need re-sourcing in the future.
