Using the push-rod comb

[Catz]

I do try the search function before posting honestly but sometimes don't find a definite answer.
Regarding the picture below, is that the correct way to use the push-rod comb? Just having a trial run before fitting the new gaskets.

Here's what worked for me :O)

Nice one. Thanks.

Hi catz

I have always used a bent piece of wire to get the pushrods in place. Found it easier than the Combe.

Hi Ellis,
yes the comb looks like it could cause a problem pulling it out from between the cylinder head inner cooling fins. If i struggle i'll think about using a piece of bent to shape wire.
Thanks for the tip.

The comb comes free fine. For me, the biggest downside is messing up the gasket sealer. To minimize this, I put the sealer on the bottom side of the bottom gasket and the underside of the rocker box mating surface and try to hold the box off as long as possible.

Another good tip, thank you.

I followed a similar route to a10gf's when doing this job.
A slight mod to the comb so that I could clamp it flush to the top fin of the head. (Pic a bit blurry, sorry.)
It ensured first-shot assembly each time - and to Richard's point, with less of the sticky mess created by multiple attempts or slippage of the tool.

There are a few ways to do this, but I followed Colsbeeza's method of bending the end of the comb down and securing with a G clamp to the fins.  Because I hadn't got a suitable small clamp, I used the biggest one I could find and clamped it onto the bottom fin of the barrel.  If you've got time, have a search.

Thanks for all the tips and advice, i've done it.
I clamped the comb down with a tiny clamp, a socket piece and one of the cooling fins, opened up the adjuster arms and shone a light into the area to make sure the little cups engaged with the rods. Job done at the 4th attempt.

G'day Catz.
I use the rubber band method as GB. 9 times out of 10 the ex pushrods go on. With the box 1/4" from home a piece of bent wire gets the inlets in there cups. The r/bands keep them there till the box is lowered and gaps set.
Cheers

Your reply got in first. That job is one of the A7/10 owners favorites.

I have better luck with dental picks , the hooked ones .

One thing I have found that makes the job some what easier is to make sure all of the rocker box studs will screw in by hand. Remove all of them before sliding the box in position over the cylinder. Once the rocker box and pushrods are in place install the studs and complete assembly.

Quite like that one!
