1974 Triumph Trident restoration Part 10, The rocker boxes 

Great video and incredible detailed. Owning a 1972 Trident I learned a lot. Thanks guys for posting. All the best from Holland 🇳🇱

Great video, thanks for sharing. After doing this exercise a few hundred times myself, might have some useful tips: 1) Take the opportunity to clean all threads in the head and on the bolts, inspect and roll the pushrods on a flat surface to check straightness. 2) I usually use WellSeal on the gaskets, just as a matter of course 3) I placed the paper gaskets under the metal cups which hold the crush rings to get the recommended crush depth 4) I mark the middle push rods with a bit of Typex on the head to identify them when looking through the hole. Sometimes they tends to "cross" during assembly with the other push rod. 5) I use some light grease on both ends of the pushrods, just to prevent them from jumping out of their cups during assembly. 6) I use "lash caps" on top of the valve stems to increase the area where the valve adjusters "hit". Of course this means shortening the adjusters a bit, otherwise they hit the covers. 7) Don't forget that there are small sealing washers under the 6 small Allen bolts. They usually tend to "stick inside". Forgetting them may cause a leak 8) Beware that with the T160 Trident the arrangement differs, hence different pushrods are used.. Keep up the good work 🙂 Greetings, Leo

Sure glad I did the tubes and rocker boxes on bare engine setting in the frame!

I'm in the middle of replacing pushrod seals and top end gaskets on an 78 OIF Bonneville. This is the first time I've taken a top end apart. As I dissembled it I realized the previous owner didn't put push rod seals in there. The front PRT didn't leak much at all but the rear one is the reason I took it apart. As I put it back together I realized why the previous owner left out the seals... using the thinnest seal I have in my kit, the gap between the head and the cylinder is way too much. And when I put it together with no seals in place, I can't lift up the pushrod tubes at all to measure for a seal. There's no gap. After doing some problem solving....I've ordered one of the thicker copper head gaskets to try to make room for the thinnest pushrod seal in my kit. I'm hoping that works, I refuse to put this thing back together with no pushrod seals like the last guy. I also have a plan B...I ordered a couple of the trident pushrod gaskets, which didn't come on the 650 or 750 twins for some reason. I thought maybe if I have a very thin gap at the bottom of the pushrod tube (too thin for the white squishy seals) I could use the thicker version of the trident gaskets, which are around .030. I may be able to create a seal with one of those. We'll see. I'm enjoying the process....and the problem solving part of it all. Although if I can't solve the problem it'll probably stop being fun. : )

Hi Jesse, Great video. Where did you find the rocker box breather cap kits? That is a great addition. Greetings from Colorado.

Hi Jesse , what are the size and place to buy the X rings, I’d really like to use them but I’m having trouble finding the right size..? Also could you tell me again the size and where to buy the linear bearing in the clutch? Your videos are very helpful and I’ve watched all of them, some twice. Almost forgot, is the X ring between the Cush drive shaft and the clutch a different size than the pushrod tubes, please advise, thank you so much
