flyingfleasteve Posted March 2, 2019 Author Share Posted March 2, 2019 As the bike stands now........ Quote Link to comment Share on other sites More sharing options...
Ron Posted March 2, 2019 Share Posted March 2, 2019 They had the long grips like an Ariel W/NG. That is a 6" grip on the throttle and a 7" grip on the clutch side. So far I have the 7" clutch side grips on my 3SW (rubber) and 3HW (canvas) but haven't found the 7" twist grips yet, except for the one on my W/NG. Ariel and Triumph had a lot of similarities.

flyingfleasteve Posted March 3, 2019 Author Share Posted March 3, 2019 (edited) Thanks Ron, I seam to remember the throttle barrel being a longer type, funnily enough the one I have soured for this bike is very long hence my asking, I didn’t know if it would need cutting down. After inspecting the clutch components further it appears that I a missing parts 79, as shown on the age below.

Ron Posted March 3, 2019 Share Posted March 3, 2019 Lucky find with the twist grip. For memory the whole thing should be over 7" long. You can buy the grips from Jeff the rubber man. Mention my name jeffalanhunter@aol.com #79 is the race that should be pressed into your chainwheel. The rollers don't sit in a groove, they sit up against the rim of the top hat part 81 and place them all round with the use of grease, before carfefully putting 81 inside 79 so that none tip. The rollers are cheap as chips but it's important to fit the correct ones. They are 'NOT' as often advertised 1/4 x 1/4 but are in fact about 12 thou shorter on the length........Length is not everything!! https://www.ebay.co.uk/itm/TRIUMPH-SET-OF-20-CLUTCH-CENTRE-ROLLERS-PRE-UNIT-AND-UNIT-TWINS-57-0394-BSA-A10/352583133774?epid=6004493140&hash=item521797aa4e:g:zZAAAOSw9EJZto8l:rk:1:pf:1&frcectupt=true Ron Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted March 3, 2019 Author Share Posted March 3, 2019 Thanks Ron, that’s really helpful. I have just bought some of the roller bearings, that for the link! I have noticed that only 3 plan clutch plates were fitted instead of 4 🤔 am I correct in thinking that today’s part number is 57-1363?

Ron Posted March 3, 2019 Share Posted March 3, 2019 The modern friction plates (superseding cork) are Surflex plates # 57-1362 I think. Only three required. I fitted an extra steel plate under the clutch cover on my 5SW as I was trying to ellimimate clutch slip whilst kicking through compression. In the end it was too much oil in the chaincase. The books says 3/4 pint, which I think might be errononious. Other Triumph guys I speak to only put enough for the chain to touch, more like 1/3rd pint. I've used ATF on recomendation.

flyingfleasteve Posted March 3, 2019 Author Share Posted March 3, 2019 Good advice 👍 out of interest Ron what’s the part code for the steel clutch plates....? Quote Link to comment Share on other sites More sharing options...
Ron Posted March 3, 2019 Share Posted March 3, 2019 The same clutch parts were used right into the 60's I beleive. https://www.draganfly.co.uk/index.php/triumph-shop/1937-1962-pre-unit-twins/category/1280-clutchpu Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted March 3, 2019 Author Share Posted March 3, 2019 Perfect! I noticed there are two plain steel clutch plate codes, do you happen to know which one is correct one? Quote Link to comment Share on other sites More sharing options...
Ron Posted March 3, 2019 Share Posted March 3, 2019 The original number for the steel plates was T415 now superseded by 57-0415. The other plates are for different models. Ron Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted March 5, 2019 Author Share Posted March 5, 2019 Hi Ron, thanks so much for Jeff the rubber mans contact details, unfortunately my email has bounced back, have you by chance got any alternative contact details? Quote Link to comment Share on other sites More sharing options...
Ron Posted March 5, 2019 Share Posted March 5, 2019 (edited) Well I don't think Jeff would change his email address as it's his only usual form of contact. But I've sent him a test mail which hasn't bounced yet. Did you copy it correctly?

flyingfleasteve Posted March 7, 2019 Author Share Posted March 7, 2019 On a separate not I checked the throttle/twist grip complete length and it’s indeed approximately 7” long. wheels have today gone off for blasting ready for painting this weekend fingers crossed.....let hope the rain holds off. All missing clutch items have now been ordered so I am hoping a good weekends work will really start to bring it all together, well that’s what I am telling myself!

flyingfleasteve Posted March 9, 2019 Author Share Posted March 9, 2019 Collecting the wheels today’s so hoping to get some paint on them and installed in the next few days. Currently I am waiting for Royal Mail to deliver my newly purchased items so I can crack in this weekend...... Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted March 9, 2019 Author Share Posted March 9, 2019 On a separate note does anyone have a set of instructions on how to test the Lucas MCR1 voltage regulator? I have a sheet somewhere but cannot seem to find it......the simpler the better, electrics are not my strongest suit 👍 Quote Link to comment Share on other sites More sharing options...
Ron Posted March 9, 2019 Share Posted March 9, 2019 (edited) I've never known how you can test a regulator as a seperate item. I always start by making sure that the dynamo 'motors' on the bench. Then if I don't get an obvious reading at the ameter when the engine is running. Or the headlamp doesn't get brighter when I rev the engine (in case the ammeter is fualty) I test the dynamo is working ok, by the light bulb method. If the dynamo is working but not charging the battery, it can only be the regulator. At this point I junk the innards and fit a solid state DVR2.

flyingfleasteve Posted March 11, 2019 Author Share Posted March 11, 2019 This weekend has enabled me to plod on with some of the smaller fabrications of parts, whilst waiting for some of my other items to be delivered. Due to the limitation of time and the weather means the wheels are currently on the back burner. Quote Link to comment Share on other sites More sharing options...
