Paul H Posted December 21, 2022 Report Share Posted December 21, 2022 This post is intended to bridge the knowledge gap from the newbies ( me included ) and the experts who keep this forum going I bought this gearbox for spares or repair from a known source . It did come with its alloy housing which I’ve removed . Note the 3 small springs are still there and the copper washer on the bottom stud . This prevent oil leaking The box didn’t include the gearbox selector though made sure the securing studs were included Is the input shaft reusable ? IMG_4920.MOV The input shaft splines ok ? The input shaft has some vertical movement IMG_4918.MOV Some general pics The next stage is to remove the cover top assembly and see what’s there .

johny Posted December 21, 2022 Report Share Posted December 21, 2022 Should be interesting as this looks to be a WE serial number box for which to my knowledge the source vehicle model has never been identified.... Link to comment Share on other sites More sharing options...
Paul H Posted December 21, 2022 Author Report Share Posted December 21, 2022 WE30 151 Though the W could well be a M upside down so ME30 151 Paul Link to comment Share on other sites More sharing options...
johny Posted December 21, 2022 Report Share Posted December 21, 2022 No its definitely WE as Ive got one but cant find that serial number anywhere and we've talked about it before. Dolomite 1850 are apparently WH or WM... Link to comment Share on other sites More sharing options...
Josef Posted December 21, 2022 Report Share Posted December 21, 2022 So I’m ready to be corrected on this, but from what I know the input shaft tip and splines don’t wear significantly enough to be a problem. (And from your pictures yours look pretty normal) The input shaft having some play is normal, a lot of play can indicate a worn mainshaft tip (expensive) or tip bearing (cheap). Asking the supplier if they know the source of the box would be interesting. Presumably they have identified a WE prefix as normally having the same intervals as a 2L Vitesse. @johny do you know the ratios of your WE box?

Pete Lewis Posted December 21, 2022 Report Share Posted December 21, 2022 pauls box has been through some previous life the black paint on the input shaft and the serial number face is from some reconditioner somewhere and the WE could be some clue rather that it being a Triumph seriial number .( it doesnt look overstamped but who knows ) input shafts/stem gears will have some rock /lift /wobble as its not yet supported by the crankshafts spigot bearing thats holds its location and wobble free Pete Link to comment Share on other sites More sharing options...

Dolomite 1850 are apparently WH or WM... The BL WSM for the 1850 Dolomite gives WE as being a 3-rail 1850 box, with WH as the single rail. I don't know where the WM fits in. 1 Link to comment Share on other sites More sharing options...
johny Posted December 21, 2022 Report Share Posted December 21, 2022 I believe all boxes for Vit 2L, GT6, and 1850 have the same forward ratios (although gear profiles are different) and otherwise the only internal differences are tip and synchro ring sizes... Interesting about the WE box, so it should be same as mk3 GT6 with small tip and large rings. Link to comment Share on other sites More sharing options...
PeteH Posted December 22, 2022 Report Share Posted December 22, 2022 To me it looks as if the Letter M has been used upside down to emulate the W?, and its not as well defined as the other stamping. Link to comment Share on other sites More sharing options...
johny Posted December 22, 2022 Report Share Posted December 22, 2022 Could be as some of the stamping Ive seen has been all over the place😂 However there was definitely never any small chassis gearbox with ME serial number.. Link to comment Share on other sites More sharing options...

WE box is 1850 3-rail, and they seemed to be short of a W stamp as I have a couple with upside down M used in its place. Gear set is identical to Mk3 GT6. 1 Link to comment Share on other sites More sharing options...
johny Posted December 23, 2022 Report Share Posted December 23, 2022 Makes sense as the GT6 box was KE so the WM mentioned in a few places probably never existed👍 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted December 26, 2022 Report Share Posted December 26, 2022 WM was Dolomite 1850; Canleys have it listed on their site. I'm sure I have a photo somewhere of the one I used on my GT6 back in the early 2000s. Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 26, 2022 Report Share Posted December 26, 2022 not checked but would a dolly 1850 have a rolled spline input shaft ???not the 10 machined spline the paint job shows its a recon,anything could be used to make up a box Pete Link to comment Share on other sites More sharing options...
NonMember Posted December 26, 2022 Report Share Posted December 26, 2022 1 hour ago, Pete Lewis said: not checked but would a dolly 1850 have a rolled spline input shaft If it's a WH prefix, then it's a single rail with fine spline input shaft. Very early Dolomite 1850 used the same 3-rail gearbox as the GT6 Mk3, with coarse splines, with a WE prefix. That's what the BL WSM says. It makes no mention of WM prefix.

Paul H Posted December 26, 2022 Author Report Share Posted December 26, 2022 Removed the top cover . The selector forks look ok to me . Initial look at the main shaft gears looked ok, though lots of play on the synchro rings IMG_4935.MOV Check all the gears for chips and the only one was this one . Not sure which one it is . Properly mangled with tooth chips all the way round . Is this the 4th Gear ring ? Paul Link to comment Share on other sites More sharing options...
johny Posted December 26, 2022 Report Share Posted December 26, 2022 Looks like the input gear and yes the synchro is for selecting 4th. Not so easy to find a good replacement as you need to look not only at the gear (good condition and correct profile) but also the internal area where the tip bearing runs....

johny Posted December 26, 2022 Report Share Posted December 26, 2022 I think the mistake might have been made early on and then repeated elsewhere. Has anyone in the great org ever seen a fabled WM gearbox? Link to comment Share on other sites More sharing options...

Paul H Posted December 27, 2022 Author Report Share Posted December 27, 2022 Thanks Johny . I’ll use this box for spares when required . My current set up for my Mk 2 Vitesse is D type OD which Uncle Pete sorted for me a while back . On reassembly Pete noticed the 1/2nd synchro outer ring might be incorrect or out of spec as it had a lot of vertical / horizontal movement. Part no 156911 . At the time I couldn’t justify a new replacement £100 plus so the box went back as is . Currently 1500 miles plus and the GB is behaving and 2nd synchro ( changing down ) is sorted and no excessive noise. I bought this box for part 156911 should it be required also to learn how the GB works Thanks for all your input I’m a little wiser now . Hopefully others have gained some more knowledge .
