TimBancroft Posted January 1, 2023 Share Posted January 1, 2023 Just changing the front hubs on my TR6 to Classic Driveline's bigger units. Having not worked on the vertical link and stub axles before, I can honestly say that I loathe the trunnion bushes, inserting them into the cast wishbones is a pain, much rather the small chassis arrangement of having the bushes in the trunnion. I have previously played around with the coil springs for the car and changing those is a royal pita as well..... The whole front suspension units on those cars seems very clumsy...think Triumph's later small chassis arrangement was superior. A re-design based upon a strengthened version of that design would have been a good idea. Link to comment Share on other sites More sharing options...
Nick Jones Posted January 1, 2023 Share Posted January 1, 2023 Never worked on the TR front end, though have spectated on a battle with a Scimitar front corner which is the same IIRC. The thing that always struck me was that the TRs have the same wheel bearing size as the Herald and Spitfire (just a bit more separation), in spite of the 6 pot lump and 15” wheels. No wonder they suffer from brake pad push-back. Triumph obviously were aware as the small chassis 6pots got bigger bearings! Good luck in your battle. May the force be with you?

As a Scimitar owner I recognise the job. Although the later Scimitars like mine had the bigger hub bearings from new. Big heavy car though and still got disc pushback until I fitted the solid bearing spacers. Link to comment Share on other sites More sharing options...

egret Posted January 1, 2023 Share Posted January 1, 2023 I took the spitfire out for a run today to a local meet at Barrington. There was a very eclectic mix of classics with a very nice red mk3 spitfire as a stand out for me (photo below is of my scruffy mk4). It reminded me that there's a leak in the top hose where the fan capillary runs, and that I need to clean the carb needles if I haven't run it for a while!

RedRooster Posted January 1, 2023 Share Posted January 1, 2023 3.63 LSD in, standard 3.89 out. No preload on the old one that I can measure, must be less than 1lb/ft. Also did the spring spacers at the same time. RR Link to comment Share on other sites More sharing options...

Also did the spring spacers at the same time. Busy morning, although if the long rear bolt doesn't act up and the front mounting plate is straight (!) it isn't too bad a job. Can't remember, what LSD did you get? Interested to hear how you got on with the spring spacers. I found them to be too thick and took them back out as they made the car sit far too high.

RedRooster Posted January 1, 2023 Share Posted January 1, 2023 Not all on one day, a festive garage break. They were too thick, I filed the inner ones to around a 1/16, the outers to an 1/8. It's a blackline 5:1 Quaife copy. Link to comment Share on other sites More sharing options...

RedRooster Posted January 1, 2023 Share Posted January 1, 2023 Supposed to be semi gloss black, just a warm day here 18degs when I sprayed it outside. Funny thing is when I touched up the chassis with the same paint it came up matt? Guess the car is colder in the garage. Link to comment Share on other sites More sharing options...

PeteStupps Posted January 1, 2023 Share Posted January 1, 2023 The brown Spitfire-6 has had some attention, stripping the rusty brake calipers. Pleased to discover it has the GT6 uprights and type 16 brakes. Pistons were very seized, took some persuasion to come out but eventually complied. I made a video of the whole process (GoPro xmas present!) but will probably take 3 weeks to edit it into something vaguely watchable... Link to comment Share on other sites More sharing options...

PeteStupps Posted January 2, 2023 Share Posted January 2, 2023 Hmm... ok I consider myself warned! Cleaning the rust out of the locating lip on the calipers is going to be awkward... maybe i'll dip them in something. Link to comment Share on other sites More sharing options...

Little watch-makers screwdriver with a small kink in the end (or even left straight) works pretty well. 18 hours ago, Escadrille Ecosse said: Bloody awful those things. It’s quite cunning, just (very) fiddly. Calipers used on a lot of VAG stuff are similar, but less fiddly somehow. 1 Link to comment Share on other sites More sharing options...
