johny Posted September 4, 2022 Report Share Posted September 4, 2022 Looks like theres different bell housings for scroll and lip type seals to fit single rail Spit boxes - certainly two different part numbers... Link to comment Share on other sites More sharing options...

johny Posted September 5, 2022 Report Share Posted September 5, 2022 Surely if the adaptors are different as shown by the measurements you have taken, the holes in the bell housings they fit in will have to be different?

Heres this from Rimmers single rail page: You can just change the adaptors. So dont know why they list as different part no. But the spare one thats bigger is the wrong one for a Spitfire. Bought a few of these scroll and oil seal type adaptors and always fit the bellhousing and are the same size. 1 Link to comment Share on other sites More sharing options...
johny Posted September 5, 2022 Report Share Posted September 5, 2022 certainly seem sensible to have a common bell housing but then Triumph werent always sensible😄 Link to comment Share on other sites More sharing options...
NonMember Posted September 5, 2022 Report Share Posted September 5, 2022 I suspect the "spare" (bigger) seal housing is for the Dolomite 1850 version of the box, and may also match the GT6. Link to comment Share on other sites More sharing options...
johny Posted September 5, 2022 Report Share Posted September 5, 2022 yes all vitesse, GT6 and 1850 (single and 3 rail) used the same seal housing which is a different part number to the Spitfire version... Link to comment Share on other sites More sharing options...
Peter Truman Posted September 5, 2022 Report Share Posted September 5, 2022 I used the Spit 1500 single rail internals into a GT6 3 Rail Gearbox case with an early Herald 3 Rail Alloy Bell-housing and Replaced the std scroll seal arrangement with a rubber mechanical seal that fitted into the Single Rail Front Cover that fits into the Bell Housing and houses the seal and that the thrust bearing carrier slides on. so it all does convert and fit! 1 Link to comment Share on other sites More sharing options...
wimpus Posted September 12, 2022 Author Report Share Posted September 12, 2022 It was a busy week last week... Front bearing fell apart on the gearbox in Fox. So the rebuild one needed to put in fast.. Thursday, friday evening and saturday morning we changed out gearboxes etc. Then it was off to meet up with the 10CR guys at the finish.

wimpus Posted September 12, 2022 Author Report Share Posted September 12, 2022 But still nothing was off 1 and 2 can crunch. Suspect the new release bearing to not be the same size. So.. did 350kms and 6.9L/100km to and from the Netherlands. Abd no oil used.. still amazed by that 😅 Not bad ! Some pics at Rolduc It was a great evening, seeing lots of people that I knew. Also helped somebody out. Link to comment Share on other sites More sharing options...

wimpus Posted September 13, 2022 Author Report Share Posted September 13, 2022 Some play in the noisy gearbox.. 3th and 4th syncro hub lost all his balls and springs due to input moving so much. 20220908_183601.mp4 Link to comment Share on other sites More sharing options...
JumpingFrog Posted September 14, 2022 Report Share Posted September 14, 2022 That input bearing is toast, and looks like the casing is too. Probably will also have not been kind to the mainshaft tip. Was the bearing anything decent or typical unbranded junk that everyone is selling? Also noticed that seemingly all your gearbox failures have been on the input end, worth checking your engine back plate is absolutely flat. I'm guessing you've already checked, just surprised how many gearboxes you're going through! Link to comment Share on other sites More sharing options...

I had 2 front bearings fail. 1 time laygear 1 time laygear shaft and laygear Etc Rear engine plate is flat, new pilot bush , straight better flywheel now etc Link to comment Share on other sites More sharing options...
wimpus Posted September 15, 2022 Author Report Share Posted September 15, 2022 Ffs.. Found some rot on the bottom connection of outrigger to chassis on the right side. Left side i've done in februari, right side looked and felt solid... Bended the previous repair away a bit.. hole in chassis itself.. Time to weld it is then.. 🙃 1 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 15, 2022 Report Share Posted September 15, 2022 the input shaft should be locked in place by the front cover/hsg there is far too big gap between baulk ring and dog teeth so looks like a thrust/spacer is missing on the mainshaft which is more likely to shift under the helical loads than the input shaft there are shim rings to set the input and rear main bearing snap rings so any movement is very restricted Pete Link to comment Share on other sites More sharing options...

Will get the box apart in a few weeks to see whats up, when i get more time.. Link to comment Share on other sites More sharing options...
wimpus Posted September 16, 2022 Author Report Share Posted September 16, 2022 Yesterday some cutting and getting out some rust. Seems they just covered over a rust hole in the chassis itself. But not to bad really To fix. 🙃 Next some stone chip once the epoxy primer is dry. Already sprayed some wax in it to. Link to comment Share on other sites More sharing options...
Peter Truman Posted September 16, 2022 Report Share Posted September 16, 2022 I was lucky with my Vitesse the main chassis box was still solid underneath and cutting the outrigger bottom out like yours was sufficient then weld in a new piece, I sprayed fish oil into the joint btwn main and outrigger to protect it. Interestingly I had previously brought RH & LH original Stanpart front outriggers to replace them but a patch was adequate, maybe next time????

Left one had a bit part welded in before my time. In the future need to look at the front anto roll bar mounting plate. The plate itself looks home made if you see the other side. Weld was again cracking, but seems the metal of the chassis is getting thin there. Will have a look on what to do in the future.

wimpus Posted September 18, 2022 Author Report Share Posted September 18, 2022 Im pretty sure the endfloat on this one is to much 😅 20220918_150436.mp4 For the rest didnt find a whole lot bad. Laygear etc all fine, mainshaft all fine. Only need all the mainshaft bearings and 3 springs & balls for the syncro hub. 1 1 Link to comment Share on other sites More sharing options...
wimpus Posted September 20, 2022 Author Report Share Posted September 20, 2022 As friday is D-day (her yearly technical inspection)... Needed to do a few things. Noticed the left top ball joint had grease on it.. another gaiter bad. Got the ball joint loose to discover.. it was rusty inside and felt notchy. Time for another one. But I do think its best to have a look at the front suspension.. Maybe change all the bushes etc, it was all replaced 6 years ago but had done 90.000miles 😅😅 Link to comment Share on other sites More sharing options...
wimpus Posted September 20, 2022 Author Report Share Posted September 20, 2022 Today after work had a warm up drive, then it was time for emissions check and front light aim check. Emissions.. started at 6,5% Adjusted 2 flats more lean, 2,89/3,10% ! So thats meets the legal limit of 4,5% But runs a bit lean, after inspection will give her a full tune up. Fronts lights needes some adjustment. But fun to drive now in the dark 😅 For the rest I just need to degrease engine and gearbox, then shes ready.

wimpus Posted September 23, 2022 Author Report Share Posted September 23, 2022 This morning D-day for Fox once again. Technical inspection time. She passed without advisory's again. And the tester told me the underside looked really nice for a 44 year old car. Told him it had +345.000kms.. he was a bit shocked 😄 In the last year she has done 17.468kms/10.850miles. 8 Link to comment Share on other sites More sharing options...
