Well that’s a bit of bad luck...turns out the screw I bought for the drive gear cog is too big at M6 x 14mm. I hadn’t realised the M5 x 10mm of the earlier models (the one I’m after) was discontinued! So if anyone wants a brand new one of the screws pictured below that fits the small bottom oil drive cog behind the clutch basket, do let me know! IN THE MEANTIME if anyone has or knows of a breaking early T595 with a decent one of these screws at M5 x 10mm, then please let me know...it’s all there is between me and the first start of my bike after a head gasket replacement.
If you know the measurements, google is your friend or a few calls to a manufacturer would mean you probably have a new one in a few days? Just make sure that the thread pitch is correct (as i'm sure you would) and viola!
Many thanks for posting. Unfortunately I don’t know the thread or material! It’s definitely a fine thread. I’m hammering everyone who’s selling T595 spares on eBay at the moment...I reckon someone will have one, fingers crossed!
But you posted it was M5 x 10mm. I think at that screw size normal pitch is 1mm, fine thread is 0.75mm. Count the screw threads over a 5mm length of screw, should get you near enough to know which it is. Or get a stock metric nut and see if it screws onto the slightly tired looking original screw. Check someone like Accuscrews, they should sort you out. A spot of threadlock on it, and Bob's your chiropodist Had a quick look. These, for example: https://www.accu.co.uk/en/68-securi...arch_category=68&orderby=ranking&orderway=asc
Just taken a look at your edit...you’ve got it...brilliant! Will be counting the threads and ordering from there! Any benefit to choosing stainless over steel?
Not really. Stainless might be less likely to rust in and cause disassembly problems but not something you'll be taking apart every 10,000 miles I don't suppose. Thread length on a 5mm screw is 0.8mm. You can click somewhere on that page for more info, gives thread length, head diameter etc. Yeah click on the pic of the screw and scroll down new page, full spec is at the bottom.
Either or either tbh as its not going to rust as it's inside the engine! Just get the correct torque number and all sweet. @Smilinjack beat me to it but totally correct of course.
I'd suggest that it doesn't need to be stainless and non-stainless usually has a higher tensile strength. What you clearly WILL need is a good threadlock on it!
Cheers, Adie, I’ve got Loctite 243 to use. I notice the new (wrong size) replacement was pre-threadlocked with a material that looked similar to the stuff on the new exhaust studs I fitted. 243 OK you reckon? I’m no engineer.
I'm no engineer either (couldn't be much further from it!) but I'd think 243 should be fine - as long as the threads are clean and dry prior to application. Proper threadlock and correct torque are key, I reckon.
Screw ordered from Accu...less than 30p! Had to go with the A4 stainless (which is harder than A2 I read) because this had the correct sized head diameter and countersinking depth
Sounds like job's a good un then. Woop woop Bearings, nuts and bolts,Oil seals will always be cheaper from stockists of those items than from Triumph, or any other motor manufacturer for that matter. They are usually very helpful too and can help with sizing etc.
Absolutely. Accu are really good, and I use Simply Bearings quite often for, well, bearings, but oil seals too. Always a fraction of the price main dealers will try and hit you with, and you can get better quality too. I once ordered some head bearings from Ebay for my ZZR1200, shockingly poor. Pretty much same price from Simply got me a set of Timkens. Lesson learned
One word...for a 30p screw...DELIGHTED! What a phenomenal service from ACCU https://www.accu.co.uk/en/
