Re: Sq4 Timing sprockets

Roger; I have the snubber, not yet in place. The dynamo is a new Longman alternator.
Paul; I am using a socket and breaker bar on the front crank, turning anticlockwise.
I will fit the snubber and try turning the engine using the rear crank.

Sq4 Timing sprockets

1951 Mk1 Simplex. Turning the engine by hand so that the timing chain travels clockwise, the chain regularly becomes slack between the camshaft and halftime sprockets. Continuing, it snatches up tight again. I have an old chain, it does the same. Looks like I am up for a new chain, but do I need to ...

Re: Club Rods are tight

You guys are good. The shells in use have a number on them: W1426-002. I looked in the box of spares that came with the project and there was little box with 8 used shells in it. Also a note on a torn envelope which I can't quite make out the last bit i think it says "standard on original shaft...

Re: Club Rods are tight

John that was a similar but different discussion. Someone else was recently offered a discounted set via the Club Spares Organiser which the big end eyes were not honed to spec. http://forum.arielownersmcc.co.uk/viewtopic.php?f=4&t=10344 My rods came from Draganfly at full price. I have had them...

Re: Club Rods are tight

Draganfly replied to my email: It may be possible that the old shells are from a car (as was often used) and your old rods were honed to suit. You could try with a new set of shells and see how you get on. The club rods are pretty good and we don't know of any issues. It didn't occur to me that the ...

Re: Club Rods are tight

I naively expected the rods to be correct out of the box. I did lots of measuring, and test fitting, glad I kept the old rods. I then honed the new big ends. This was a lengthy process, trial fit, remove, take shells out, hone, clean, shells in, trial fit, repeat. Times four. Took me hours, did not ...

Re: Club Rods are tight

Temptation is to use the old rods, or the new ones with reduced torque. Both sound like bad ideas. I thought this would be an easy part of the job. I will also email Drags,

Club Rods are tight

1951 4G Mk1. I bought new rods through Draganfly. My engine was in good condition. Journals are standard size. Engine was reconditioned 2500 miles ago by a known club man (18 years ago). I followed the new rod instructions explicitly. I decided to re-use the shells. I filed off the tang to 12 thou a...
