racey Posted July 2, 2019 Report Share Posted July 2, 2019 Hi Just wondering if anyone can help with a little problem, I acquired a spare cp engine and gearbox with a tr6 I bought and try as I may - I cannot find any identification stamps anywhere on the casing there are none and there is absolutely no evedence of ever being one or one being removed. There is a date mark on the right hand side that looks like it was scored into the casting sand reading 19/2/75 and that's all apart from the usual raised casting numbers....... Any ideas would be gratefully appreciated. Graham Quote Link to post Share on other sites
rcreweread Posted July 2, 2019 Report Share Posted July 2, 2019 Graham - I've seen that or something very similar on a Stag box previously but it still had numbering stamped onto the clutch cross shaft boss. Can you supply a photo of the whole box? Does it have an OD unit attached - if so what are the serial numbers of that? Cheers Rich Quote Link to post Share on other sites
Mike C Posted July 2, 2019 Report Share Posted July 2, 2019 The Moss and Rimmer's websites used to have details of where to find component serial numbers on a TR6. Quote Link to post Share on other sites
racey Posted July 3, 2019 Author Report Share Posted July 3, 2019 Thanks for replying Rich & Mike here's the side I would expect the I D. to be but nothing at all anywhere on the casings! It's a bit of a mystery to me. The internal are like new which had me wondering if it could have been a replacement box supplied by Triumph /Leyland??

Mike C Posted July 3, 2019 Report Share Posted July 3, 2019 You're right- mine has the S/N stamped on the housing behind clutch shaft . Your GB has never been stamped in this area. Quote Link to post Share on other sites
rcreweread Posted July 4, 2019 Report Share Posted July 4, 2019 Well it’s got a TR cross shaft and a reversing light switch so with its age, it would appear to be a TR6 A late TR 6 box of that vintage should have a higher first gear than earlier ones - I think that means it should have 32 teeth on it It could still be an ex stag box - most oh the ones I’ve seen are stamped on the off side boss not near side like most others - is there anything there? must go as off to Goodwood! cheers Rich Quote Link to post Share on other sites
racey Posted July 4, 2019 Author Report Share Posted July 4, 2019 Hi guys, No stampings on the other side either... Or anywhere else so I will count the gear teeth to see if this can shed some light! Hope thee weather holds good for Goodwood Rich Quote Link to post Share on other sites
rcreweread Posted July 5, 2019 Report Share Posted July 5, 2019 Hi - just one more thought - I take it the input shaft is 1.25” tr one and not the 1” saloon one - have you got a pic of it? Goodwood yesterday hot and busy! Today even more so!! cheers Rich Quote Link to post Share on other sites
racey Posted July 5, 2019 Author Report Share Posted July 5, 2019 Hi Rich Yes it's definitely 1.25" splined shaft with what looks like very little use as most of the marks you can see are storage marks really, so maybe it is a new/recon factory unit? I must get round to counting the gear teeth! Graham Quote Link to post Share on other sites

Any ideas would be gratefully appreciated. Graham My suspicions are that the casing was supplied as a spare only to replace a damaged one with the internals coming from else where! That would explain why there is no stamps on the casing which are only put on compete units. Bruce. Quote Link to post Share on other sites
Litespud Posted July 6, 2019 Report Share Posted July 6, 2019 (edited) My tranny has a similar casting date (“25/3/75”, IIRC) in the same location (the handwriting’s different, though ) Since it’s in the car, I can’t see if there are any other stamps. I assumed it was standard, and that the ‘75 tranny was further evidence of the Frankenstein nature of my car (a ‘72, and the tranny has an A-type O/D) Edited July 6, 2019 by Litespud Quote Link to post Share on other sites

racey Posted July 8, 2019 Author Report Share Posted July 8, 2019 Thanks Stuart, I've scanned every inch of the outer casings and absolutely nothing what so ever - totally unstamped Graham Quote Link to post Share on other sites
