Introduction on Honda Tools w/photos
Posted: Sun Mar 13, 2011 10:54 pm
This project began for me due to all the tool kits being sold on eBay and my search for a correct one for my cb77 project. After emails with 48 lesco on the 305 forum it turns out he was also working on the same project and was kind enough to supply the information he had already collected. I have expanded my research beyond the cb77 kit and I would like to receive criticism and feedback on the information provided. I have just ordered everything that is still available from Honda and when it arrives I will show a post and any differences. I have also emailed Kowa to try to attain some information on tool casting die marks such as the A and RK in a circle on what I believe to be early tools and the RK only tools. I believe the switch to RK only Marked tools was in 1973 and the black handled screwdriver was introduced in 1974.

Double Head Spanners
Every tool kit has two open-end wrenches for common hex nuts and bolts. These were referred to in the British sense as "double head spanners" in most descriptions. During 305 production in the mid-sixties, Honda abandoned the old Japanese Industrial Standard (J.I.S.) in favor of the Modified J.I.S. (I.S.O.) standard. This caused a reduction in the width between flats for all hex nuts and bolts except for 6mm. It would seem that this should have affected the wrench sizes in the tool kits, but there is no reference to anything but the original 10x14 and 17x19 wrenches. It is possible that the new smaller hex size nuts and bolts were never used by the factory (the new finer thread 3, 4, and 5mm screws certainly were). Interestingly, in my CB77 owner's manual, the wrench sizes are listed in terms of the thread diameter, not the width between flats, as 6x8 and 10x12. At any rate, the two "double-head spanners" are meant for all 6, 8, 10, and 12mm nuts and bolts.

Axle Wrench
Every tool kit has a double-ended box wrench for the axle nuts, a.k.a. "axle spanner," or "ring wrench." The CB77 axle wrench is 23x26mm to match the front and rear axle nuts. The CA77 wrench is 23x32mm. The 23mm end is for both the front and rear axle nuts, and the 32mm end is for the rear axle sleeve nut. The 23mm end of these wrenches is also the ideal tool for removing the tappet covers.
Early CL77's had the same arrangement as the Dreams on the rear wheel with a large sleeve nut holding the sprocket assembly in place. The rear wheel could be removed without loosening this sleeve nut, only the 21mm axle nut had to be removed. The early CL77's used the same 21mm axle nut on the front wheel. The wrench listed in the CL77 parts fiche is 21x23mm. The big end of this wrench could also be used for the tappet covers as per the post by LM on the 305 forum. Starting with CL77 1014496, the front axle nut went to an arrangement that was captured by the front fork clamp, and didn't require an axle nut to be removed for a tire change. The rear axle went to an arrangement similar to the CB77 with a 26mm nut. These models were probably equipped with the CB77 23x26mm wrench and the small end was now used for the tappet covers as per other posters on the 305 forum. See photos
Axel wrenches from left to right first 2 are CB77 and the rest are cl72/ CL77 Notice the Logo switches direction. The second CB77 wrench fits the rear axle on my 1967 CL77 with chrome fenders.
From left to right Ca95, Unknown marked Sanki same as ca95 wrench, Ca77, Ca77.
The Ca95 wrench measures 29x23mm. The second wrench marked Sanki and is the same size as a ca95.
Possible Ca95 or ca160 wrench Notice the manufacturer is not Kowa. It is marked Sanki
There is also one more known variant, I have not seen one yet and I do not know if both ends are 29mm, this is from the Honda tools Special Catalog printed in 1969.
Pliers 150mm
every tool kit has the same set of 15cm long pliers. All pliers I have seen are marked with the HM logo, I have 5 pairs and the grips are different on couple of pairs, I do not know if this has year of manufacture significance. Part Number: 99002-15000 PLIERS (150MM not available from Honda
Tappet Adjusting Wrench
Stamped steel. Two-headed for the Super hawk and late Scramblers with dual leading-shoe brakes, and single-headed for the Dream and early Scramblers. The single-headed wrench is offset to make it easier to use a 10mm wrench on the nut. The CB parts fiche lists a "no longer available" -010 version. The wrench in the CA95, CA160, CA175, and others looks identical to the CA77 version but is 3mm and will not work. Clarification needed here

Spark Plug Wrench"
What complicates the search for a correct spark plug wrench is the switch from a 10 to a 12mm spark plug thread (and corresponding switch from 16 to 18mm hex) that occurred after the 1961 model year. There are also numerous part numbers with incomplete super-session history for what I think are very similar wrenches. Basically a stamped steel socket wrench aka "box" wrench. The latest version is still available from Honda but probably looks different than the original.”
I only have one spark plug wrench and it is 18mm hex or 12mm plug. I have a box of spark plug wrenches so I would love to see yours.

Fuses and Cotter Pins

Tool Bag
The tool bag for the CB and CL models share the same part number. The CA has a different one. I have an original tool bag from a 1964 CB77 that is a green canvas. Others I've seen are black or blue or black and blue vinyl. The part number of the CA160 and CA95 is the same as the CA77/72.
