ferny Posted October 2, 2006 Share Posted October 2, 2006 How easy is it to shove a 1500 j-type into a Herald 13/60? I know it can be done, just not sure if everything goes together properly or if bits needs to be changed. I've noticed the clutch is bigger etc. Link to comment Share on other sites More sharing options...
Deleted User Posted October 2, 2006 Share Posted October 2, 2006 I've just done this with mine ..If you keep the 13/60 clutch cover and use with a dolly 1300 friction plate ..this will keep the same size clutch and have the correct no of splines to match the input shaft on the boxyou will need to modify the tunnel a bit so that you can get to the prop boltsFit an overdrive gearbox mounting...i had to make a plate up to bolt this to as the existing one didn't line up ,but that was just a piece of plate with holes drilled in to match up with the chassis and gearbox mountThen you need a prop 45.5'' long [either have one shortened to length or find one that's allready to size] you will need a large flange on the gearbox end and a small flange on the diff end and that's about it apart from wiring the overdrive in Link to comment Share on other sites More sharing options...
Jason Posted October 2, 2006 Share Posted October 2, 2006 I did it too on my Herald - it's well worth the effort and transforms the car, of all the mods I'd done to that car it was probably the most noiceable and satisfying Link to comment Share on other sites More sharing options...
ferny Posted October 2, 2006 Author Share Posted October 2, 2006 I'm looking forward to synch on first as much as anything. ;DThanks for the info. :)I think I read a while ago that a Vitesse propshaft works? Link to comment Share on other sites More sharing options...
heraldcoupe Posted October 2, 2006 Share Posted October 2, 2006 The Vitesse propshaft is 47" long, it works with the shorter D-type overdrive gearbox. To fit the single rail J-type box you're going to need a custom 45.5" propshaft, unless there's a non-Triumph been made with one of the right length.I prefer the 3-rail gearbox to the single rail of the 1500, and I can't get as excited as some people about the J-type overdrive over the D-type of the earlier cars. Best all-rounder for my tastes is the Spitfire MkIV overdrive gearbox - 3-rail box, D-type overdrive and the Vitesse propshaft will fit (though you may need to shift the engine forward a smidgen). That's the setup I'm putting into my next Herald, replicating what was in one of my previous favourite cars.Another personal preference, overdrive switch on the steering column, rather than on the gearstick. Longer lasting and (for me) easier to use.Cheers,Bill. Link to comment Share on other sites More sharing options...
Nick Jones Posted October 2, 2006 Share Posted October 2, 2006 I have fitted this box in a Herald and it works fine. It is a slightly trickier conversion than a 1300 3 rail plus D-type due to the extra length needing special propshaft. Clutch wise you just need the fine spline friction plate from a late single rail-equipped 1300 Dolly or Toledo. Change quality of the 1 rail is better in my opinion, but few agree.........I have a complete surplus gearbox in stock.......

Deleted User Posted October 3, 2006 Share Posted October 3, 2006 The only potential downside of a single rail in a Herald is prop fouling. That extra couple of inches in length of the gearbox means that the prop sits slightly higher in the tunnel. In some cars it can foul the angled strengthening plate welded in the tunnel under the handbrake. Move the whole thing slightly over to the left on the mounting plate to avoid.

Clive Posted October 3, 2006 Share Posted October 3, 2006 I did a typical bodge when fitting 1500 od to my herald. Used the vitesse propshaft, swapped one flange and made a spcer 1" thich to move the engine forward. OK not ideal in terms of balance, but worked fine and handling not affected. Also avoided the costly business of propshaft shortening (was well over £100 locally).Made my own monting plate from a git of 4mm thick 40mm wide steel bar, just drilled holes to suit. Easier than using a proper plate as many seem to be "wrong" anyway and need redrilling.This method keeps prop flange in the right place too!CheersClive Link to comment Share on other sites More sharing options...
ferny Posted October 3, 2006 Author Share Posted October 3, 2006 Thanks for all the info. :)The way I understand it, the d-type is easier to fit but the j-type as synch on all four gears and is slightly stronger. Right now I get frustrated not being able to put it into first when I want sometimes so that's my main reason for wanting the j-type.I agree on the column switch. Things can always be adapted. ;D Link to comment Share on other sites More sharing options...
heraldcoupe Posted October 3, 2006 Share Posted October 3, 2006 The MkIV Spitfire gearbox has synchromesh on first, which I neglected to mention in my earlier post. It's the best all-rounder for my tastes,Cheers,Bill. Link to comment Share on other sites More sharing options...
