Rover SD1 Vitesse LT77 Rear Oil Seal

I have a TVR 350i which is fitted with a Rover SD1 Vitesse engine and gearbox. The gearbox is an LT77 suffix E. I want to replace the rear oil seal but there seems to be some confusion as to what the part number is. Rimmers state UKC3949 as for suffix A to C and FRC6084A for suffix D, which as I understand is pretty much the same as suffix E. Other suppliers quote UKC3949 as applicable to any LT77. What should I be using? I have seen it stated that UKC 3949 is not compatible with the Suffix D gearbox. The TVR seal number is 035F 232A which I can get from a TVR specialist but it is £20 +P&P which seems quite expensive when it is only really a standard Rover part!!

Hi, I've just done a quick google round and found two things.

Mark Gray has the UKC3949 seal for £2.75.

There's a brief thread on V8forum with the details you asked. UKC3949 51mm O/D, 32 I/D, FRC6084 55mm O/D, 37 I/D.

For ref. LT77 rear output shaft lip seal - The V8 Owners Forum -

Thanks for that. Maybe best to pull the old one out first and measure it then!!

Just measured the shaft of the flange. It is 38mm so the FRC6084A would seem to be the right one.

Thanks again!
