Good to see someone doing a video of the intricacies of setting up a triumph cylinder head, far from straight forward, don't know why nobody sells different thickness pushrod tube seals over here, then there's the torqueing down sequence. Good luck and well done.
The later pushrod tubes / tappet blocks with wedding rings are a much better bet.The mods to early heads are to machine deeper seal holes & bevel them to avoid tearing the seals.
I think there's a guy making adjustable pushrod tubes for Triumphs. I saw a set of them on a TH-cam channel called Dirty Shirt Richter. (He's machinist who does a lot of work for Baxter Cycle's in Iowa.) I'm not sure if they're for sale yet, seems like he's still in the "testing" phase to make sure they work well. I put a T140 head together recently to replace top end gaskets and PRT seals. It was my first time doing any top end assembly and I was worried about getting those seals correct. I was quite happy that she didn't leak when all was said and done.
Great work Ian. That's a very good looking engine.
Thanks, not bad considering it was just a box of bits!

Yes I thought that was odd about the tube seal availability

hi Ian one step closer and looking good, just thought which engine would you prefer to work work on. kind regards Adrian.
I think I prefer working on BSA's, much simpler design!
Although I prefer crank bearings to BSA bushes. Swings and roundabouts!
Makes one wonder why Triumph did not adopt VW beetle style push rod tubes?
