WayneW Posted October 4, 2019 Share Posted October 4, 2019 Hi, I would like to assemble my OSGIKEN LSD in my n/a open diff, I'm quite curious to see if I'll get the job correctly done or not, I've always heard this is a quite tricky job ? Do anyone have any good link (thread, YouTube, …) about this ? Cheers ! Quote Link to comment Share on other sites More sharing options...
Scooter Posted October 4, 2019 Share Posted October 4, 2019 I think there are a few tricky bits (patience/experience ideally required?) Teeth meshing/setup is one (main one?) I think. Quote Link to comment Share on other sites More sharing options...
WayneW Posted October 4, 2019 Author Share Posted October 4, 2019 Thanks, yes definately require to be patient ^^ this will be the case. I already read the Supra manual several times, I think I've understood a lot, but some parts are still not so easy for me to understand...

rider Posted October 4, 2019 Share Posted October 4, 2019 I just exchanged an open diff with a new LSD unit in my ancient Ford Mustang and did look seriously at whether to build a new diff myself or buy one in ready built that would just bolt in place. I elected in the end to go for the fully assembled diff assembled by a back street racing outfit in Kentucky that was ready to fit for many reasons, namely; I had never built a diff before, I didn't have the equipment to set the preload torque and backlash that would cost £60 for cheap Chinese tools that I would likely only use once. Diff experts were quoting me £200 to build (+ parts) and £250 to build and fit. It was one of the easiest decision I ever made to have a ready to fit unit sitting by the car ready to fit that is now in the car and works well.

WayneW Posted October 4, 2019 Author Share Posted October 4, 2019 Yeah, thing is I want to learn working on my Supra, engine has been done, gearbox a bit too, the last things untouched is the diff ^^ Quote Link to comment Share on other sites More sharing options...
P_Bazz Posted October 4, 2019 Share Posted October 4, 2019 I've done pretty much everything on the drivetrain/suspension side of the Supra myself but brought the diff to a specialist to install the TRD unit. You need some very specific pieces of equipment to do it correctly. The main thing is measuring the "drag" of the pinion when you're tightening the nut and crushing the washer. As well as the equipment needed to measure backlash and the ability to "read" the paint markings on the gears correctly. I'm not saying it's impossible but it's going to require a lot of money on tools, patience and trial and error to get it truly correct.

Style Posted October 4, 2019 Share Posted October 4, 2019 When I was getting the suspension and underside of my car overhauled, the diff was sent away to a specialist to be built as it's an area, like said above, that requires a lot of knowledge, expertise and tools to do properly.

WayneW Posted October 7, 2019 Author Share Posted October 7, 2019 I don't think specifical knowledge is really necessary, general precision mechanical knowledge and patience, the Toyota Book is well done… I think all the steps have to be well studied before doing anything. Pics to come in the next days =) Quote Link to comment Share on other sites More sharing options...
