KV6 Engine Bank Nomenclature

Matt_75 · 8th January 2024, 07:15

Morning,

Something that I discovered recently is that RAVE refers to the main timing belt end of the KV6 engine as the Front, but calls what is commonly referred to as the front bank the Left Hand (LH) bank, and the rear bank the Right Hand (RH).

Until now, I mistakingly thought the front bank was the RH one and vice versa. I thought that the banks were named when looking at the engine from the front, but it appears Rover named them looking from the gearbox end. Is this typically how it's done? If not, any ideas why Rover named them this way?

Thank you

I suppose one way of looking at it is to go back to the days of rear wheel drive? The front is still the same as the 75 (cambelt end), as is the rear (gearbox end. The left side of the car and engine are indeed left on a rwd. Come the time of the Mini and we went to fwd, front of the engine now to the rhs of the car, using the same engine as its predeccors (A35,A40 etc) so the lhs of the engine is the front of the car. Evolution takes us to the KV6 with the left of the engine being at the front of the car. That's my take anyway.

Yes Matt.
The convention dates back to longitudinally mounted engines when the front is where the crankshaft pulley is.

Ah, this makes sense. If the engine were mounted longitudinally, the "front" bank would be on the left hand side of the vehicle and the "rear" on the right hand side. Thank you both

Yes, viewed as it were from the drivers seat in the old days when crank pulley was up front . !

And the cylinders of the L/H (Front) are indicated by odd numbers (1,3,5) and the R/H bank by even numbers (2,4,6)
To make it even more interesting some diagnostic programs refer to these cylinders with letters, L/H bank A,C,E and the R/H bank as B,D,F

It's even more fun for me as a Canadian when you Brits use the terms Offside and Nearside as those are not used here and totally confuse me, and my ZT-T is LHD so I have to carefully consider when a Brit uses "Driver's Side" and "Passenger Side"!
