Title: Tappet Adjuster tool...any good?
Post by: Athame57 on December 13, 2018, 06:21:34 PM
I've ben thinking of adding one of these Tappet adjusters to my tool kit, has anyone got experience to share, ie are they worth buying? https://www.ebay.co.uk/itm/Honda-Tappet-Adjust-Tool-for-CB350F-CB400F-400-4-350-400-SOHC-Four-1970s-HWT026/251957752640?hash=item3aa9da3340:g:YowAAOxyOMdS-RBK:rk:35:pf:0

Very similar to genuine Honda workshop tool kit.

Personally I feel a good ring spanner and stubby screw driver is a good as those in the right hands.

I got my Honda tools from the same supplier and they are all fine.

That is bloody expensive! The OEM tool is PN 07708 0030400 and is about £4  ;)

Bought a "genuine" Honda tappet adjuster many years ago.
No spanner part to loosen/tighten the locknut,  just a square drive to suit the tappet with a  small plastic handwheel. Used with a cranked 8mm ring spanner this seems to work ok.
I always have to back off the adjustment a small amount ( from .002")  when tightening the locknut as the set gap closes slightly despite resisting the torque with the adjuster tool.
I guess the fancy version works like the old SPQR tappet tool to make life easier?

I bought the DS tool around five years ago and, quite honestly, rarely if ever use it. The tool itself is just too bulky to fit easily within the access hole. I still prefer to use a screwdriver and cranked ring spanner!

Hmm... I've never seen the adjusters... so one tool mentioned here is slotted, like the head of a screw?  And the other is a screwdriver?  They can't both work, can they?  And the tool in the DS photo shows neither?  I guess more research is needed...  :-\

How do members get so confused ! The 400 has the tappets and the tool that i listed is used  :o Some other SOHC's have a different tappet that all is required is a flat screwdriver  ;)

I've always used a key that I believe was for winding a clock, works a treat.

Whilst most locking nuts are 10mm there are at least 3 tipes of adjuster top
1  screwdriver slot
2  small square
3  reverse screwdriver slot
