Ian Foster Posted October 2, 2023 Report Share Posted October 2, 2023 (edited) I managed to download a Vitesse parts book and found reference to it here. I assume it is the single bolt, dowel part No. 132872. Searching with this part number on Canley's website, gives a substitution of Pt No. HB912 which a 3/8" x 1 1/2" bolt. As standard, a 1 1/2" bolt will only have about 1/2" that is unthreaded and the engine back plate plus the bellhousing is more like 0.75", so a cut down 1 3/4" bolt might be more precise.

Phil C Posted October 2, 2023 Author Report Share Posted October 2, 2023 3 hours ago, Josef said: if it’s important then Triumph would’ve written it down somewhere! You’d think so eh? From the comments it would appear that quite a few of us are unaware of this. Looking closely at my back plate, the hole in question looks like it may once have been threaded. I was thinking may be the 3/8 dowel bolt fixed into the plate and remained there when removing the gearbox. This could explain it not being mentioned in the WSM? 1 Link to comment Share on other sites More sharing options...
Iain T Posted October 2, 2023 Report Share Posted October 2, 2023 (edited) No it's just a Triumphism! Why make it easy..... The hole was never threaded that would have cost money. Plus golden rule is mating thread depth must be at least 1/2 diameter of bolt/screw preferably full diameter.

Phil C Posted October 11, 2023 Author Report Share Posted October 11, 2023 (edited) Thought I would follow up having now successfully completed the RBRR. The Vitesse didn't miss a beat covering 2148 miles of (almost) continuous running over 48 hours......and still no sound of a budgie 😊. So just to repeat my thanks to all who helped get the car back together in time. I know it's a rival club but for anyone considering entering the next RBRR I would certainly encourage you to do so. Its a challenge but great fun. Of course we had to contend with that horrendous Scottish weather of the Friday/Saturday which certainly added a little jeopardy to the occasion and took its toll with a number of retirees. By contrast the sun was out at Lands End and most of Sunday was top down motoring. 😎 We also raised over £1200 for the Huntington's Disease Association and I think around £70,000 as group..... not bad for a bunch of old codgers in equally old cars! The start is a glorious place. Wall to wall Triumph's of all models. After 13 hours driving through Friday night/ Saturday morning we enjoyed a full Scottish at JOG. .....and another at Lands End some 24 hours later.

Ian Foster Posted October 11, 2023 Report Share Posted October 11, 2023 Well done Phil and John Considering that the car was in bits 7 days before the start and the challenging conditions, that is a great achievement. Glad the budgie was left in Lyme Regis. Very pleased to have been of some help. Ian 1 Link to comment Share on other sites More sharing options...
Iain T Posted October 12, 2023 Report Share Posted October 12, 2023 You and the car made it, a great result! London-Peking next? As to the next rbrr it's on my must do list but I'll need a co-driver as none bar one of my friends are old car nuts and the one that is likes his 8 hours kip. Applications on a postcard please...

Steve P Posted October 12, 2023 Report Share Posted October 12, 2023 (edited) I did the RBRR in my Vitesse in 2012 but had to retire in Cornwall due to a snapped driveshaft and a 3 wheels on my wagon moment as the rear wheel detached with the brake drum still attached. Tried again in 2014 in my Herald 13/60 and completed it with only 1 issue which turned out to be a fuel hose sucking in air. Changed at 3am in the rain in Aberdeen. I wont be applying Iain as i think, done that, move on to something else.. Congrats to Phil and John for getting round. First time i tried sleeping in a moving Vitesse convertible, and probably the last. Steve Edited October 12, 2023 by Steve P Link to comment Share on other sites More sharing options...

Steve P Posted October 12, 2023 Report Share Posted October 12, 2023 I heard tales from other teams of them having a curry and a few pints the night before set off. Definitely roof down for that, whatever the weather. S 1 Link to comment Share on other sites More sharing options...

Difficult agreed! I have fitted heated MX5 seats which can recline about 45 degrees, a couple of soft pillows, ear plugs and an eye mask (for daylight sleeping).....but definitely no beans! On the motorway sections it was just possible to sleep 😴 but elsewhere dozing/resting eyes was more likely. Link to comment Share on other sites More sharing options...
Ian Foster Posted November 29, 2023 Report Share Posted November 29, 2023 (edited) As an addendum to Phil's original thread, I can confirm the apparently 'secret' or little known information that the Vitesse/GT6 rear engine plate and bellhousing should have a 3/8" dowel bolt at the 5 o'clock position. Two engine plates and a bellhousing inspected at Chez Jones....and yes they have it. My engine a gearbox separated today....and yes they have it as well. Mine had a 5/16" bolt at that location so I'll be replacing it with a 3/8" dowel bolt when I reassemble. I'll also be replacing the pilot bearing as I could have worn unevenly if the bellhousing was slightly off. Every day is a school day!

Did you have any transmission vibration? If not you are lucky. As said previously my car was undriveable over 45/50mph until I fitted the magic 3/8 dowel bolt!

Thanks for the useful info. Is that a sleeve/short tube in the bell housing, that accommodates the shank of the 3/8" dowel bolt?.

No its just a close tolerance hole in both the bellhousing and engine back plate. By comparison the holes for the starter motor are standard clearance, so slightly bigger.
