Topic: second gear missing teeth

[mattzuba]

I was sneaking in a day of riding last week on my '77 cb750k, not often you get to ride in wisconsin in January, and broke a few teeth off of my second gear. Ive got a few questions, will the gears out of an 1980 cb750k fit(there is a set on Ebay that closes in a few hours), how hard is it to change it out, and is there anything I should look for when I have it apart?

I do not think they would fit. Thees are two different engines the 80 is DOHC.I have a 70 and an 81 and I believe the DOHC is wider.Dannie

Nope. Different animals.

I've got some spare 550 gears, I don't know if one of those would work.

[mattzuba]

anyone know a good place to find a new gear?

Take the engine apart a see what other damage you have…….. you may find it cheaper to find another engine.

What exactly happened? Second gear may only be part of the problem!

i was driving it a little hard, shifted to second and it made a bit of a clunk, now when ever i shift to second you can feel it skipping where the tooth was. ill try to get some pics it i take it apart this weekend. what else could be messed up?

Its mating gear, its shift fork or dogs, and anything else the broken tooth may have hit on its way down to the pan. Best get that engine torn down and have a look- hate to see you buy one gear from DSS and find out you need a handful of other things. Used 750 engines can be found for not-too-much still, keep your eyes open.
Also, as much as some here may hate the place, good deals can be found by hitting up the guys over at http://www.hondachopper.com . They're dedicated solely to the SOHC CB750's, and some have collected their own shrines of spares for just such an occasion. One member just picked up a spare engine for $100, not a bad deal considering all the extra bits you get besides the gear(s) you need now.
