Re: Front Forks Mk 1 Square Four

2 way damping is a major suspension improvement. Ariel forks are only rebound damped, and the design is such that the rebound damping does not work on the initial part of the rebound stroke. The standard damping relies on oil being sucked through the small hole(s) in the stanchion above the bottom b...

Re: The new Project

Paul good work. Out of interest did you keep a tally of the hours involved in making the alternator. From memory Bennett suggested about 150 hours. It took me a bit more than that although I did at one point alter the design in my head, made a component only to realise after completion it was wrong ...

Paul
I am certain that a lot more than just me would love to see a lot more photos, so a photo a day would be great. It was after all worse than a basket case at the start and now the phoenix has risen from the ashes (literally).
A fine creation such as that one deserves to be admired by all.

Re: WTB timing cover

Wade There is a small foundry near me that until recently was operating full time. He operated from his home on a small rural property but closed full time operations recently.

Re: New Member

Actually the snail cam adjuster was used up until 1950. The revised stirrups 4980-50 and 4982-50 and the adjuster bolt 4989-50 were first introduced in 1950. The parts books show the prior stirrrups 4980-39 and 4982-39 were used up until that time. The engine is fitted with a VH timing cover so to m...

Re: WTB timing cover

I need a HS timing cover but that one is in very poor condition. I can get one cast, polish it and have it engraved for a lot less than that one would cost post included.

Re: SQ4 how to advance valve timing

Adrian If the cam has been reclaimed it is very likely that the grinder did not grind the lobes to cylinders 2, 3 and 4 to precisely 90 180 270 degrees from cylinder 1, especially if he got no 1 out of sync with the keyway. Before going any further I would check the lobes for the other cylinders. It...
