1/2 inch head dowels

Anyone fitting half inch head studs to an RB (should be all rb25 and 30 blocks)  They suit OEM replacement also.

Need these!

We have recently discovered that many people don’t use dowels when converting to 1/2 inch head studs, they are absolutely crucial to stop the head from walking around and hurting your gasket seal!

The reason you can’t run an RB26 type M12 / 12 mm Stud in an RB20, 25, or 30 is because they are originally 11mm thread, And if you drill it out and tap half-inch UNC you need around .7 mm per side of the material to tap through to form a reliable thread.

End result with 12mm thread is that you end up with roughly .4mm at best, threads do pull being grey cast, then you have to pull your whole engine down again and fix the problem but once you have gone and pulled the stud thread through, you have to go to 9/16 which is too big or helicoil/ threadsert.

We see it happen all the time so please don’t risk it and just go a 1/2 inch stud, use these dowels problem solved.

Bought for my one year old niece. She loves the bright pictures and being able to push the button to make the animal sounds. Great buy.

Fun animal book with Eric Carle illustrations!
Format: Board book
Some of the noises the animals make feel a little strange, but my toddler loves to push the buttons! I do like that it says the name of the animal before making the sound the animal makes - gives some vocabulary practice when my daughter is reading independently.

All the grandkids enjoy these, of various ages.
Format: Board book
The grandkids always enjoy Eric Carle sound books. The older one reads the stories and the younger one likes to just push the buttons and listen and then say what the animal is. The sound is always nice and clear and the photos on the buttons are easily recognizable. As an added bonus these were offered at a great holiday price.
