DaveN Posted December 23, 2020 Report Share Posted December 23, 2020 Bit surprised at that Marco. After all if a g/box fails it’s no big deal. I could understand something like a different design of axle or other component that directly affects the steering and handling. Quote Link to post Share on other sites

Z320 Posted December 24, 2020 Author Report Share Posted December 24, 2020 (edited) Hi Dave, the car it is registered as a historic vehicle and this gives me some benefits at Germany, mainly less tax and I'm allowed to drive in restricted areas (air pollution). Therefore the car has to be mainly "original" and in well condition. I'm not allowed to use my MX-5 Mk 2 seats (tolerated), my IRS adjustable brackets (long discussions last year), in the strictly sense no modern starter (perhaps they don't realize it) and no alternator (I don't use). And I'm shure: no MX-5 gearbox at all..... Ciao, Marco Edited December 24, 2020 by Z320 my bad english Quote Link to post Share on other sites

Ciao, Marco I went through similar many years ago when I sold one of my MK2 Jaguars to a German friend, TUV didnt like that it was on wires so I had to provide catalogue proof of them being an option and send him some "Continental" spinners.

Z320 Posted December 25, 2020 Author Report Share Posted December 25, 2020 (edited) Next is to look for the rear gearbox mounting, today I did just some preparation for that / to get the gearbox on the spare engine again, "all" bolts have been already glued in the adapter. This a a dummy spigot "bearing" made of POM to check the center again. This is the way I want to use the original gearbox mounting, "ears " cut off and new drilled. Maybe it makes sense to be able to move the mounting more foreward, about 40 mm is possible with a small modification. Doing this will give me later another lovely benefit, some of you perhaps already know or ask yourself how I handle a upcoming problem. To decide more the gearbox has to go on the engine and its trolley, half a year ago I marked there position of the crossmember.

Z320 Posted December 30, 2020 Author Report Share Posted December 30, 2020 (edited) This is 16 mm to contact... Ready for contact... Contact! Position II Contact! The MX-5 gearbox has landed on planet TR! Next is to bother the crossmember This will be the next puzzle How ever it will be, I cannot pull the gearbox back enought to fit it with the crossmember in. I will see.... Ciao, Marco Edited December 30, 2020 by Z320 Quote Link to post Share on other sites
Z320 Posted December 31, 2020 Author Report Share Posted December 31, 2020 ups, last day of the year and a 28 mm hole in the gearbox! Sadly this project has to be finished next year. I've been told at the UK the "lucky pig" is not know as a symbol, so let me tell you at Germany its a symbol for "Good Luck!" And that's what my lucky workshop pig (a she) and I wish you for 2021! You see her twinkling on the window board, she's always sitting there, watching me, the hole scene and the stuff I'm doing. See you next year, stay safe and healthy.

Z320 Posted January 4, 2021 Author Report Share Posted January 4, 2021 Hi, in 2021 just idea finding how to fix the rear end, the steel sheet is in the position of the crossmenber. Sadly the gap up to the gearbox is only 20 mm Not enough to use the original (modified) mounting - and I want to let the rear end some millimeters down.... I guess this could be the way a DIY crossmember could fit, lowered about 30 mm. Quote Link to post Share on other sites
Z320 Posted January 6, 2021 Author Report Share Posted January 6, 2021 Yesterday I only picked up the dimensions of the prop shaft on my TR for the new one. And had some ideas how to fix the rear end of the gearbox. Next the crossmember has to be out of the TR and fixed on my trolley. I hate working in the cold garage....

Z320 Posted January 8, 2021 Author Report Share Posted January 8, 2021 (edited) Hi, the crossmember is out of my TR4A but I can't get it in the position I marked it in May 2020 on my trolley because the gearbox touches it as long as I can cut something off the gearbox there is no problem this way it works..... to fing out how long the new prop shaft has to be, made from the rear ent of a TR and the front end from a MX-5 prop shaft The new one will have no slide in the middle like our TRs have, it sildes in the gearbox itself and is lubricated with oil! This is one option to fix the rear end (the wood will be metal, of course), but I'm not shure about. On the right side you see why I can't move more forward Another idea is to use another silent block in front of the speedo drive to bear the weight there. I found one from the AH Sprite, perhaps somebody has one in his workshop to measure? Ciao, Marco Edited January 8, 2021 by Z320 Quote Link to post Share on other sites
stuart Posted January 9, 2021 Report Share Posted January 9, 2021 I think it might also be difficult to fit a propshaft like that to an IRS chassis when fitting the box to the engine in the car. Stuart. Quote Link to post Share on other sites
Z320 Posted January 9, 2021 Author Report Share Posted January 9, 2021 Hi Stuart, you are ABSOLUTELY RIGHT, I expect the diff has to go out. And because the MX-5 gearbox about 90 mm longer perhaps the tunnel has to be cut out for some centimeters. To get the gearbox in the TR will be a own chapter, I hope my gearbox crane helps me.

Z320 Posted January 9, 2021 Author Report Share Posted January 9, 2021 (edited) Hi, if someone wants to look in his workshop for the AH item, please stop it, I go a different way. This looks like much effort but it is not and it solves the problem of the gearbox angled in the frame automatically. Sometimes it's the best to let all tools stored and give the thoughts a free run.

Z320 Posted January 19, 2021 Author Report Share Posted January 19, 2021 Hi, at the moment I'm at this point - and OK, it was some effort but with this "bridge" I can fix the gearbox nearly at the same position in the TR's frame as the original TR gearbox. To determine the position for a bar 90° to the bridge I have to go out in my cold and dark garage and wait for the ordered cogs and parts for the speedo angle drive.... Ciao, Marco Quote Link to post Share on other sites
Z320 Posted January 23, 2021 Author Report Share Posted January 23, 2021 (edited) Today I did some bending for the new gearbox crossmember, on top a test bend from 0.6 mm steel sheet to pick up the dimensions, next the one I bended from 4 mm steel, sadly it could be wider on the top (wrong calculation) for the speedo angle drive. This way I saved the situation, this gives me more space, now I only have to cut "the wings" smaller. Sorry Malcom, no progress on the EPS, this challenge was more interesting... Ciao, Marco Edited January 24, 2021 by Z320 Quote Link to post Share on other sites
Z320 Posted January 28, 2021 Author Report Share Posted January 28, 2021 Lovely, I had to cut nothing smaller. Here it is drilled, the surface needs some sand blasting and finally will get a black oxide finish. From another project I still have this PU bushes and 1" pipe pieces. Through "the bridge" is a M10 x 100 mm bar with two steel bushes, that's some kind like on our cars falcrum pins. Like this, the four holes on the rear are for the new exhaust bracket, the original TR part of cause will not work with this construction. I think I will make some more modification to get the crossmember more stiff. Currently I wait for the cogs (from China) to make the angle drive, this will be with a ratio gear to speed the cable up, the MX-5 output spins too slow for the TR speedo. What I did not check until now is the spin of the output (same way / reverse), this is next after the TR crossmember is back in the TR under the TR gearbox.

No way I could ever attempt it, but I am getting vicarious pleasure from it. Kind of the opposite of schadenfreude John Quote Link to post Share on other sites
