Triumph Twin Superblend Conversion (Norton Commando main bearings)

In this video I demonstrate how here at Gordy's Goodworks I can convert ANY unit OR pre-unit Triumph twin cylinder engine to use Norton Commando "Superblend" type main bearings. These heavy duty bronze-caged cylindrical roller bearings deal with torsional and radial loads immensely better than the stock ball/roller setup. As a result you will notice the engine turns over much more easily, revs much more freely, accelerates noticeably better, and produces more power. If you need this conversion done please don't hesitate to contact me.

WOW!! Great work! Wish my Bonnie had this bearing setup.

top job - always needing some love these engines with your modification will keep triumph twins running fine for ever !

Nice work mate, I like the approach you have taken of ‘if it looks and feels right, then it probably is’. There is a lot to be said for experience and knowing how things work, not everybody has had the opportunity to gain the depth of knowledge that you obviously have, but your no bull**** manner is what has built engineering throughout the ages, Well done! I run a full CNC workshop, mills and lathes, but I wouldn’t even contemplate trying to do this on my T140 myself, mainly because I really don’t have the time to give to it and I don’t want to start something and not be able to finish it in a timely manner, nor do I want to rush it. You may well see my Trumpet bottom end come in your door one day. Fabian

Brilliant video. Background music was a bit off putting. When I try to learn something important I do not want any distractions. When I am doing something technical to my old Brit bike I will not even have a radio going. I shut myself into my work shop so there will be no distractions until I work through the problems I am having. I feel that I am the luckiest man on earth as I live on my own with a beautifully equipped workshop where I can work in peace. Everything except breathing is secondary to the enjoyment of working through a tough problem in my workshop. Perhaps when you make another video the radio can be turned down all the way to off and I can concentrate on what you are saying 100%. Still it is a great video and I fully agree on what you are saying about the different types of bearings.

Excellent video, great to see a real engineer in action.
It also looks like you have an understanding wife!

Thanks for posting this! I learned a few more things about crankshaft bearing conversion :-)

I wonder what type bearings were used in my Rotax ? Guess we will find out soon. Ron Wood did say to use Roller Bearings instead of stock after any big bore kit is installed. And also said to use a two bearing set up as to handle the extra wear that the much stronger motor puts out.

Do a Timkin bearing conversion. They have the proper size and no machining needed. They are also the superior bearing.

Hi; a T140 does not need a shim actually.
Are those Nourish s crankshafts? (I cannot understand exactly many of what you say; not clearly the audio) I assumed that it do not have sludge trap so what is that hole that looks like that?
Thanks

FFS write a script and read it! You have a lot of knowledge that needs better delivery.

Hey buddy are you still doing this conversion if so could I have your contact details

You may have a good understanding of main bearings but you put me to sleep.
