Nigel Clark Posted July 8, 2020 Report Share Posted July 8, 2020 Odd that it's listed for 2000 and 2500 engines because as we all know, the stroke of these engine's cranks is different. Part number 308034 is a Mk2 2 litre crank. Nigel Link to comment Share on other sites More sharing options...
Colin Lindsay Posted July 8, 2020 Report Share Posted July 8, 2020 GT6 Mk2 also, according to the parts list. Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted July 8, 2020 Author Report Share Posted July 8, 2020 The advertiser's description appears rather vague except for the part number which would definitely make it a 2.0 litre crank rather than a 2.5. litre crank. The crate lid has the part number showing on the top line so long as the crate and crank belong together. Link to comment Share on other sites More sharing options...
dougbgt6 Posted July 8, 2020 Report Share Posted July 8, 2020 I think from the last picture the stencil says 17684. What that means, if anything, I don’t know. Doug Link to comment Share on other sites More sharing options...

NonMember Posted July 8, 2020 Report Share Posted July 8, 2020 I must say, to my eye the "light surface rust" looks like it will need more than a "light cleaning up"! 1 1 Link to comment Share on other sites More sharing options...
Gary Flinn Posted July 8, 2020 Report Share Posted July 8, 2020 Looks like it needs a regrind on the Mains for sure, the Big end Journals don't look too clever either? These used to be available from TD Fitchetts at Telford (I purchased one for the rebuild of my Mk2 Vitesse engine way back). Not sure if they still have any left though?

Pete Lewis Posted July 8, 2020 Report Share Posted July 8, 2020 canley have them £198 no rust NOS so £175 is not a great bargain https://www.canleyclassics.com/?archive=engine-number-identification-chart&ptno=308034 1 Link to comment Share on other sites More sharing options...

Agreed. My (limited) experience with NOS cranks is that they may be production rejects and really need a grind to get them to properly match the bearings even when not rusty. However if you happen to have a set of VP2 shells in standard size....... Nick Link to comment Share on other sites More sharing options...

The engine I rebuilt with it is still in my GT6 to this day and has required no further attention beyond regular servicing. Whether there are any of that quality still kicking around NOS is a different matter! 1 Link to comment Share on other sites More sharing options...
