Maybe we can save some shipping if we get a couple of sets.</div><div><br></div><div>Note too that Bastuck has dog box gear sets including one using the J-type overdrive. When I contacted them last fall, they had none in stock and there was no production scheduled.<br></div><div><br></div><div>Failing that option, there's the "Dolomite Close Ratio Gearset". This consists of a different input shaft and main 3rd gear along with the corresponding layshaft gears. You need to work the case to get these to pit, but they work great. These are helical gears. I've used this setup for around 20 years, and it is really really good. Note: for the best total gear ratio option, get a later TR6 gearbox with the 16-tooth 1st laygear.<br></div><div><br></div><div>Now, the drawback to the helical gears is apparently excessive thrust forces and they effect the layshaft thrust washers as well as the layshaft needle bearings. If you make torque and you have any end float for the layshaft, you will spin the thrust washers and wreck the case. There are some workarounds to compensate for excessive end float.</div><div><br></div><div>Note too that because of torque multiplication, the layshaft needle bearings on the 1st gear end of the layshaft get beat really, really hard. One fix is to install a double bearing on the layshaft (or buy a new one from Moss or another source) that is set up for the double bearing. I've had Quantum Mechanics install the double bearings, they seem to work better than the stock setup. But even with that setup, the layshaft still gets pounded and you need to keep an eye on it.</div><div><br></div><div>As you may know, a lot of the racers are gravitating away from the stock and/or modified Triumph gearboxes mostly because the quality consistency of replacement parts is all over the place and you need to know what you're getting to spot the differences. That said, frequent oil changes and paying attention to the detritus in the oil, you can stay ahead of problems.</div><div><br></div><div>If you're going to build a good gearbox, it will cost you as much or more than some of the conversions out there, hence a lot of folks switch to Toyota/T5/Rocket, etc.</div><div><br></div><div>Hopefully you'll get other good advice on this list, but that's where I'm at right now (too). The Quaife gearset in the TR gearbox seems like the most "vintage" solution, but ALL of the options have pluses and minuses. In the spirit of full transparency, I'm also looking at Super T10 transmissions which are the same as the old Muncie "Rock Crusher" and there is a gearset available with a 2.43 1st, 1.63 2nd, 1.23 3rd and 1 4th which is pretty close to the Dolomite Sprint setup. And the gearbox is 70 pounds which is really close to the stock box. Also, if you want to dish out more $$$, Gear Vendors has an overdrive that bolts to the T-10, I haven't researched that enough to see if there are any particulars, but it is an option, albeit around $3k. But you get a BRAND NEW overdrive. Just sayin. A drawback to the Super T10 is that you will need to make or source a bell housing, but that is do-able with a combo of a trashed TR gearbox, a competent machinist and more $$$. ;-)<br></div><div><br></div><div>Regards,</div><div>Bob Lang</div><div>339-927-4489<br></div><div><br></div>
