Hello; how do you manage to use the socket arm (into) the socket due to the gearbox spindle touching? I saw that some people weld another socket to the big one to have the space but I do not see that in yours...thanks
Anytime. Thank you for posting the videos. I was always afraid to even touch the triumph but after seeing your videos and lunmads videos I started working on the bike. The problem I have now is oil soaking the chain when riding. I’m pretty sure its this shaft seal.
Ben is there a seal on the other side of the shaft? I’m getting a gear oil leak on the sprocket. I’m pretty sure I changed this seal in the past but still getting the leaking
@@fsyed13 Hey Fahad, the 1-11/16 is the size of the front sprocket nut for earlier Triumphs(actually a Whitworth size but 1-11/16 is close enough), and the size for the later ones is 1-7/8, I think they made the switch for the 5-speed gearbox around '72 or so and they were switching from Whitworth to SAE around the same time.
It's a bad start when the sprocket cover is getting the shit knocked out of it with a screwdriver, no wonder there aren't any decent engine cases left...
Thanks for posting Ben..

In that video I was able to get the socket arm part way in. I have since then cut flats on the end of the socket so a wrench will fit over it
I have to change this seal on my t140. It leaks oil. Maybe with this video I will be able to do it. Thanks for the video!
Jeez thanks James. Appreciate your feedback👍

Hey Ben. Bummed when video didn't record seal removal. I have a chain that always looks freshly oiled. Is that most likely this seal? 1970 t100.
@@pauliebotssame here. My leak is on the sprocket. But I changed this seal

Ben, do you still work on these bikes? If so where are you located?
Hi, very useful video. What size socket do you use for the main drive sprocket?
The output shaft rear chain sprocket nut is 1 7/8 or about 48 mm
@@benvdh9658 I read on the forums yesterday that its 1-11/16? is the 1-7/8 a little loose?

Have you tried the smell test? You should be able to smell if it's engine oil or transmission oil.
Ben's Britishbikes I will have to double check I have not rode the bike in a couple of years. I will pull the bike out soon though and investigate
How did you break the seals to get them off?
And what lubricant did you use on the seals when replacing them?
What did you apply on the seal before you installed it ?
I use rtv sometimes

With the advent of adhesives, these covers are almost impossible to get off anymore. If you have a better technique do share.
A claw hammer?!?
