A Real Emergency Push Rod Tube

[Ron LaDow]

Now in limited stock and just tested on the dyno at The Stable.
These install from the head side, and require no tools to fit. If you use your car, this could save you a towing charge.

I just received a sample tube from Ron. He had sent me pictures earlier, but seeing it in the flesh is really impressive. I certainly can recommend it to everybody.
Thanks, Ron!

Ron,
How exactly do you install one of these?

Dan,
Here's the Install Instructions (we'll see if the 'X-pixel' limit allows the image)

Sorry, Dan. "The extension pdf is not allowed", and since I'm more interested in old cars than proving I'm a geek, it'll have to wait.
If you email me, I'll send it as an attachment.

Sorry Ron. Posts can include image files in various standard image file formats but not PDF files which is apparently what you attempted to post? A PDF is not an image file. If you want to email it to me I think I can convert it to a JPG image file and post it for you.

Best regards,

[Ron LaDow]

OK, another try.
Let's see. I can try printing the pdf, and then scanning it and then see if the image is worth a crap:

Almost as much fun as banging your head against the wall, but with somewhat better results.
You can also check with Alan or Tim B.. Dunno if Vic has actually fitted one yet, but he's not sending the sample back.

[Barry Brisco]

Ron, that image looks pretty clear to me! Good job.

Best regards,

[Sterling Vaden]

Are the circlip slots the same distance from each end? If not it would help to indicate which is longer.

On the first illustration the arrow seems to point to the head end, on the second illustration, the arrow seems to point to the case end. It is not clear whether the arrow is indicating the orientation of the tube or the motion of the tube. I suppose it is the motion. Either way, for clarity, the tube orientation should be the same in both illustrations.

Why not pre-assemble the parts to the tube (except the circlips) before inserting the tube in the head?

Sterling,
That's the problem with the print/scan/post image. it's not clear enough to answer your questions. But the 'real thing' is.
The lengths are not equal, since I wanted to retain the 'windage extension' on the case side.
If you fit the parts to the tube, you can't slide it through the head push-rod-tube hole; they must be fitted after the case end goes through that hole.

[Sterling Vaden]

Oh, now I get it, the case end of the tube has to be inserted through the hole in the head from the outside (rocker box side). It can't be inserted up through the middle, under the cylinders.

Sterling,
The problem with tubes that install in that manner is that you pretty much have to remove the exhaust and air channel to get them in.
This installs with the removal of the cover, the rocker and the pushrod; that's all.

Ron,
Is the tube intended purely as a temporary repair, or can it be left installed permanently?

Jay,
The first ones delivered went a a rebuild set; intended to be there through the next rebuild.There's no seams to split, no joints to leak:
