jackri Posted March 29, 2012 Share Posted March 29, 2012 Good afternoon, morning or goodnight - wherever you are.I'm in the fortunate position of having a rather lively '69 Spit MkIII which has a 2.8ltr lump at the front. As you may expect, this translates to a lot of horses spinning up the rear end handsomely. Downside is that the clock, I am sure, is ticking with regard to the standard 3.63 diff.So......I need to stick a stronger unit in & the Quaife ATB looks like the sensible choice ahead of a plate type. But, after consultation with Matt at Quaife, it seems that there are no 'methods of application' & it is down to the individual to get it right, or all to easily, wrong. I don't want to do the latter, so I look to my fellow compadres with such units at the back to see if there are any instructions out there in Triumph Internetland.Your assistance & instruction is truly appreciated.If you need any more info - please don't hesitate.ThanksJack Link to comment Share on other sites More sharing options...
James Posted March 29, 2012 Share Posted March 29, 2012 Be aware you'll probably snap shafts with a standard Mk3 rear end. Link to comment Share on other sites More sharing options...
TimW Posted March 29, 2012 Share Posted March 29, 2012 buy the Quaife and send it complete with the diff to Mike Papworth (pm me for tel no) and he will sort it. Link to comment Share on other sites More sharing options...
CHRIS211083 Posted March 29, 2012 Share Posted March 29, 2012 Tim, I'm sure someone told me Mike was not well and therefore not building gearbox or diff's until his health is better.Chris. Link to comment Share on other sites More sharing options...
That Man Posted March 29, 2012 Share Posted March 29, 2012 I thought it was the crownwheel and pinion that was the weak link :-/ so would adding a lsd change anything?Gordon Link to comment Share on other sites More sharing options...

I haven't heard any different but will do some digging. He also had a LSD on his bench to fit in a 3.63 spitfire diff. Link to comment Share on other sites More sharing options...
Steve P Posted March 29, 2012 Share Posted March 29, 2012 Quoted from another thread by Bodders.Hi allMy gearbox is knackered - reverse gear has lost some teeth.Just tried Mike Papworth only to find that he is taking some time off for health reasons. Canley's cannot supply (because they get their boxes from Mike).Can anyone recommend a good/trusted supplier for a Spit 1500-OD gearbox? Link to comment Share on other sites More sharing options...
Gt6s Posted March 29, 2012 Share Posted March 29, 2012 I have a quaife on 3.63 also with a lot of grunt, build up is the same a building a stock diff, you will as routine need to fit new side bearings set the preload without the crownwheel fitted after that shim the mesh. Dead straight foward. Link to comment Share on other sites More sharing options...
thebrookster Posted March 29, 2012 Share Posted March 29, 2012 Like Chris, I seem to recall hearing that Mike was taking a bit of time off just now, and it was only recently that I heard it, certainly within the last couple of weeks.Hope whatever it is he does well, he is one of the good guys!

Not sure I want canley's units.I am concerned about Gordon's comment on the crownwheel being the weak link...!Any other experiences out there? as there are some beefier cars than mine out there.CheersJack Link to comment Share on other sites More sharing options...

Engines, not had issue with, but gearboxes is a dark art in my mind - so never even opened a diffThanksjack Link to comment Share on other sites More sharing options...

GT6 M Posted April 2, 2012 Share Posted April 2, 2012 just slip the bearings and shims in at an angle (Trust me this works) great Tinkerers think, an work alike . ;)But ill add to that, use of either a copper hammer,or a hard nylon one to nok bearing cups back.
