New DT cam tappets (followers)
« on: 13 Oct 2013 at 22:14 »
For sale, new Dirt Track cam tappets (part #8774-2).

Also fits: OC, 1925-28 TT, G/H28, F/G31-32, and 1934-35 OW/0W1.
Can be retrofitted to OB and RA with replacement of pushrods and tappet guides.

Including 7/32-33 thread adjuster screw (part #4360-1), and jam nut (part #h76).

The tappet is machined from 9310 nickle alloy, case hardened to 0.040" depth. The shank is center-less ground and the head is lapped on the face and sides.

The adjuster screw and jam nut are CNC machined from shock resistant S7 tool steel, vacuum heat treated and then air tempered to HRc57.

Fully interchangeable with the original, including the special 7/23-33 Douglas threads.

So if the ends of your tappets look like this:



Or the stems are worn and scored, or someone has tried to tap the adjuster thread to a new size and made it sloppy, then here is your chance to replace it.


Cost is $100US per tappet, adjuster screw and jam nut included. Packing, postage, and insurance at cost.

Jeff,

Yes the cam tappets with adjuster screws and jam nuts are still available. By the way, you can use the forum PM or email function, rather than having to place your email address in a public post. See the links below member's names on the left; you have to be logged in as a member to see them.

Jeff,

(4) tappets with adjuster screw and jam nut would be US$340.

Postage options to Sydney, Australia are:
Priority Mail International, Small Flat Rate Box (free), 6-10 days, online delivery confirmation, US$24.75
First Class Small Package, padded envelope (US$2), no delivery estimate given, no delivery confirmation, US$16.90

The online postage calculator is not displaying the insurance options, so I am not sure what to add for that, but it would be at cost like the postage. I have been shipping the tappets in padded parcel envelopes, and they seem to be arriving undamaged. I also place them in a zip-loc plastic bag to protect them from possible damp.
