Hello Everyone, help please! I am in the process of putting the clutch back together and refurbing the primary chain case so that it will hold some oil! There was none in it when I dismantled it, not surprising though since there was no gasket, no breather pipe and no drain plug! But what oil do I put in there? The handbook says SAE 10, is there a modern equivalent? The other suggestion that the handbook has is to dilute engine oil with paraffin to stop the clutch plates slipping!! I am also slightly concerned about modern oils reacting with the cork plates which are in surprisingly good condition. I did find something called Castrol TQF on the net, is that any good? Andy

Hello, anyone going to be there with Triumph 3HW or similar? Andy

Hi Einbeck Well, the part number won't be what I expected as after counting all the teeth on each gear they clearly aren't wide ratio gears but the standard gears instead. What is needed is the mainshaft fourth gear and the second gear which locks fourth onto the mainshaft! Will have to check the parts book

Having plucked up the courage to dismantle the gearbox and try and found out why it keeps jumping out of top gear, it turned out not to be a worn selector cam as the common cause. The first sign of what trouble may be inside was that the main shaft nut was only finger tight and the clutch housing had been moving about. I think the whole shaft had been allowed to move which has led to excessive wear on the teeth between 2nd and top. See the photo. It also turns out that although the gearbox casing is stamped WR for Wide Ratio the gears in it are most definitely standard ratio!! anyhow now need to replace the gear......damn! are they easy to find? Or can the gears be rescued??

Well just to end this story, got a friend of mine to make up a suitable spacer but here is a picture I found on the net clearly showing the spacer. It's item 29 thanks for all your help once again chaps

Amazing what still turns up, you can't help wondering what else is still out there waiting to be discovered!! andy

Thank you to everyone for the advice. Andy

Thanks once again Ron.

Thanks Ron and Guy, i thought it was a bit strange that there was nothing between the two plates especially with the two big nuts on either side. It's no wonder my plates are buckled. Time to talk to a friendly engineer with a lathe!! :cool2: Thanks once again Andy

Hello All, i guess this this subject has been mentioned before for a number of different vehicles but I would like to know what the modern equivalents are to HD50 and HD10 which is what the 3HW handbook says should be used in the Engine and Gearbox (HD50) and primary chain case (HD10) i have seen modern equivalents to Straight 40 oils etc but are they ok to use or is ok to just use modern synthetics etc any thoughts? many thanks Andy

Hello Everyone, whilst working on the clutch I had to remove the left side footrest which is mounted on a common stud that goes right through to the opposite footrest. The stud goes through the two mounting brackets on the back of the engine and here is the question. Should there be some sort of spacer between the two mounting brackets? There isn't one on mine and it looks to me like the nuts on each end of the stud had been over tightened at some point causing the mounting brackets to buckle, hence the question!! Andy

Thanks Ron, can you tell me what the pipe does on the other side of the inner casing? Ie is it just cut off flush or does it go up/down etc

Hi Ron, couldnt help noticing that there is some sort of pipe in the primary timing case shown in your photo. Is it a simple breather pipe? I've been working on my 3HW clutch and it clearly doesn't have this pipe and there is just a hole in the inner part of the primary chain case. Do you have a closer shot of it? abdy

Hi Ron, many thanks for for the rapid response, as ever! Andy

Hello Everyone, I'm afraid I need some help again! I am in the process of fitting a "newer" gearbox into the bike so that I can refurb the "original" one. I notice that there appears to be a blanking plug or plate missing from the drive side of the box as I can see the end of one of the shafts. I presume that if I fit it like this I will end up with oil all over the floor! So, has anyone come across this before and can you get these plugs or is it just as easy to make one up and tap/seal it in place? Waddaya Fink? Andy

Hello Folks, can an anyone tell me where on the sleeve the Don R badge is supposed to be stitched on the battle dress tunic? I think it's supposed to be the right sleeve but where? cheers Andy

Hello Everyone, in the process of swotting up on the technical stuff for the work I need to do on the 3HW I have found several references to "Knurled Washers" being fitted to the girder forks. These are said to be "free to rotate" Well, they are so free on mine that they are completely missing! Anyone have dimensions so I can get some made up or can you still get them from somewhere? I'm not entirely sure but I think there are supposed to be 6 fitted, is that right?

This is a brilliant piece of footage, thanks very much for posting it! Would be great to see more like it. Andy

Hello Folks, thanks for for all the help with the Webley age! Next silly question is, how long should the cleaning rod for a Webley be? Got one which seems a tad long. Either I've got the wrong rod or the wrong holster! :-( Andy

Hi Sean, I,ve got the same problem!! I removed the plunger from under the bottom of the box and found it has a worn top and the spring is damaged. This plunger goes into the cam plate for the gears, so if the plunger isn't doing its job I'm hoping that's what's causing the gears to jump out. If that ain't it as you say its strip the box!! anyone else had this problem? Andy

Ahaaa! mystery solved! After a bit more digging it seems that uncle was in the RA HAA number 8 regiment before he came out in 1947 and number 8 was the Belfast Regiment. Hence the hand. Thanks is for the steer guys. andy

Well, I must admit I thought the "hand" was something to do with Ulster but as far as I know my Uncle never had anything to do with Ireland or any Irish Regiments. He spent most of his Army career in the Royal Artillery and Combined Ops out in North Africa and the far East!!! The insignia above the one in the photo I believe is Anti Aircraft. Bit of a puzzle! Andy

Hi Folks, Have been ploughing through various sites on t'internet trying to identify the insignia on my late uncles battle dress tunic, Found most of them but can anyone please identify the one in the photo? Many Thanks Andy

Many thanks to you all for the info. Andy

Many thanks once again Ron. Will check it out. andy
