In the process of putting the head back on to my T110 (9 stud head).

I seem to have problems with the push rod tubes. These are castlelated on the top.

I seem to remember that the white seals go on the bottom and the thicker black seals on top.

I have put the black seals in the head before trying to push the head back down into the tubes.

My problem seems that the new black seals seem too tight. When I try to gently tighten down the head bolts, the castellation crush in (far too much).

The top seal previously was an orange seal with lots of silicone seal!

Help greatly appreciated,

Regards

Pat

ps Do I put the push rods in after assembling the head or before (doesn't seem to be space before).

Hi Pat..I've only had a few Triumphs in 40 or so years so I'm no expert...

However, there are multiple versions of both the pushrod tubes and seals for different engines at different times...I would advise finding a Triumph specialist who knows what they are selling and establish that you do have the right set of parts in hand.....

Try 'Monty's Classic Motorcycles'..01822 617010...He's a pal of mine who deals mainly in Triumph spares, works on the bikes and knows his stuff..

You'll also find him on the internet if you 'google' the name above and he has an e bay shop.....Ian

Thanks Ian.

Problem is that the T110 is a bit of a cafe racer bitza, so the manual is only kind of a help.

Looks to me that the push rod tube seal at the top just isn't the one for either the head or the tube or a combination of both. It is just too tight.

The whole procedure reminds me of crank case end float on an A10 (or the way I ham fistedly did it) in that you have to assembly things to check the tolerances and then take them apart again (possibly harming new bearings) to shim it!

At least it is only rubber seals here....so long as I don't warp a head.

The gasket sets come with two types of the white seals usually, one is for use with the t140 type ring that goes round the tappet block and the other was for the little cup that went on over the tappet block, they usually supply both types in the gasket set.
I always used to put the black o ring over the tube before fitting as you could see that it was going in ok as you put the head on, the head usually sat about 1mm off the barrel before you tighten everything up. You have to watch the seals as they go in as sometimes they pop out of the groove.

I think the head is not T110. Maybe they were 8 as opposed to 9 stud.

Put it back on, but the rocker cover gaskets are not the right ones, so have to leave it be for now.

Thanks for your help.

I think the black seals should be placed at the bottom before you fit the push rod tubes and the white ones go on top of the tube.
The black ones are much thicker and stronger than the white ones, right ?
Interesting...
But like Ian said it may be different on different models.

Let us know how you get on, oke ?

I feel for you mate!

The number of times I have had this problem with my old 9 stud pre-unit Triton and every time I forget to write down what I need for next time. As with Dave I put the O ring on first and then try and aim for a combination of washers that end up with around 1mm “crush”.

There were so many different combinations possible with different models the manuals and spare parts lists are not much use.

Good luck, and when you have the right combination..write it down

Cheers
Pete

Ian's exactly right - just call Monty. He's been building Triumphs over 40 years, and knows 'em all. Also been a great help to me.
Push rod tubes on Trumpets are NOT all the same. Bitsa or not, Monty can sort it out for you.
Additionally, you may obtain the Autumn 2013 issue of Vintage Bike Magazine(TIOC - Triumph International Owner's Club) publication and get the entire scoop on your own. John Healy's write up is spot on. You should be subscribing to that publication, anyway.

Hi Bruce...I've known Monty since before he left the Royal Marines and got a job in a British Motorcycle shop in Plymouth many years back...I was a good friend of the shops owner and worked in there part time myself...

When the shop closed Monty started up on his own and now lives about 5 miles away from me...I've used him for most of the Triumph parts I have bought for my 1970 T120R and his knowledge of the Triumph models makes the whole thing very easy (and his wife Anne always makes me a coffee when I visit the shop!)...

She is as keen as he is and does all the wheel rebuilding as well as helping with the orders, shipping and running the e bay shop...

For Triumph I would certainly recommend them...Ian
