Rob has pointed out the nub of it, reliability aside, the mechanical fan is brilliant when it’s needed least and close to useless when it’s really needed. Nowadays we’re faced with a lot more traffic and stop start than when these purely mechanical fans were the preferred solution. Niall

Electric for me, I would go with either Kenlowe or Spal, both are quality, around a long time and used extensively in motorsport. Having a manual override switch is a very good policy and simple to do, costs little. In terms of difference to balance if you had the rotating parts balanced I would say yes eliminating the fan extension would likely make a difference if it was balanced with the extension on. But was it? If you are thinking about as supplied by Triumph then it wouldn't have been balanced as a full rotating assembly anyway.

Hi Richard, here are the Mayday part numbers. AE012/ES PTFE Endless Split Back Up to Suit BS012 (I didn't actually use these, just got them as experiment, I liked the Spiral ones more when I had them in my hand, where they might be useful is if you do have corrosion and wanted to move the quad ring on the shaft away from the corrosion if you see what I mean). AE112 PTFE Spiral Back UP to Suit BS112 Q-112 Q-112 Nitrile Quad Ring Niall

Thanks Andreas, appreciate the info. I think I have found a supplier for low volumes of suitable CuSn12, obviously its much harder to get than the SAE660 or PB1 but as its been proven in use so to speak I'll just stick with it if I can. I have two engines to do so no harm having a bit of spare material. I'm undecided on whether to go concentric or eccentric at the moment, one of my blocks has the recess at the top of the bore so it will have to be decked anyway and that combined with the eccentric small end might just leave me with too much to skim off the piston top for comfort in order to k

Thanks Andy, I have dismantled now and find that both cams seem to be fine so I will use them along with new followers. I'll have a look at what the kent ones are like and come back to you. I presume they'll be just fine for standard CP cams. I probably need to look at the thing holistically as I am going to go with the roller rockers so I would imagine I'll have to get the rockers and push rods from same source, need to find out if that extends to the followers as well. Niall

Thanks Roy,I'm OK on used ones. Niall

Hi Alan, no just on the outside, the side you will be placing the clamping plate against in other words. Niall

Hi Steven, I have both a pit and a scissor lift, I put the pit in years ago when I was building the garage and lifts weren't even an option outside a professional garage, by the time my family and work got to a point where I could be fooling around with cars again the lift situation had changed and at reasonable cost I was able to put in a full height scissor lift. The scissor lift is just a game changer, I considered changing it for a two post a couple of years ago just because its sometimes a clearer work area underneath using a two post rather than scissor, for chassis work etc. I didn't do

Thanks guys, always nice to bounce it!

Hi all, I'm overhauling an early 6 cylinder engine this winter, from disuse the engine was locked up when I got it. I took the head off before removing the engine from the car and broke a cam follower in the process. My own fault, they were gunged up and just a bit tricky to get out, I had a great idea and made a simple tool out of the rawl bolt, super job, it got them out really handily, the only problem being some idiot just went too far with one of them and instead of leaving it a little bit longer of a soak time decided to tighten up the rawl a little more. As homer would say, "doh, too fa

Hi Peter, the quad rings and ptfe backers definitely work, I've had them in two years and about 4,000 miles now and still not a drip. Niall

Lot of making in that! Same length primaries though. Nice.

Thanks Peter, that's what I thought, just wanted to make sure they weren't **** as so much of the Chinese origin stuff is. I ordered 12 of them this afternoon and even got a bit of a deal. I've never come across it before but I googled MaXpeedingrods discount codes on the net and a site popped up that lists discount codes. Tried a few that didn't work (as Hamish's didn't) but after a few goes one worked, 9% off. I'll be trying that again!

Thanks Bob. Niall

Hi guys, its 3 years later now, whats your current thinking on these rods? Any failures?
