Steve try DASH engineering, they are heavy industrial but may have some leads for you, otherwise try the yellow pages........do they have them here in WA? or your ol mate google

sorry mate,, east coast

Any one know of a good machinist to undercut gears in Perth

[Stevexs]

cheers will go with the machinist look like the way to go

[pgnz]

depending on how hard it's ridden, there's about three choices,

 1. spend big dosh on unobtanium new cogs (good luck on that one..)

2. spend nil dosh and grind and hack and undercut at the gears freehand with a fiddly bloody dremel/die grinder and hope for the best... may "work" for a bit but no way is a freehand dremel "fix" going to match-up perfectly flush all those slots (probably ok for nana-style riding though hehe)

3. spend a bit of dosh and throw the cogs at a gear specialist/machinist for under-cutting, they've got the precise real-deal machinery/setup for dead-accurate grinding






these one's undercut by  machine, few years back cost about a hundy to grind all 4 cogs  (1st-4th & 5th-2nd)

first gear has the holes that accept the dogs off 4th, what you,ll find has happened is the end of the dogs will have rounded off and will have also taken the edge off the holes,

mostly comes from race changes where the load is on the dogs right up to the point they separate, and you get a massive weight on a very tiny amount of area,

if your going in, you might as well do the gears that form 2nd also.
you,ll more than likely find they,re on the way out too

Hi Steptoe does 1st gear have dogs or does it just accept 4th gear dogs

[steptoe]

to save you some dollars, pull them out and maybe a visit to a local machine shop to put a cut  back bevel on both faces and refit

[Stevexs]

Thanks hoping that wasn't going to be the reply lol i will have to replace it as it is a sidecar outfit and first gear does a bit of work

[steptoe]

Steve, the dogs locking the gears together have rounded off,, there is no fix other than replacement, or strip and back cut the gear at the least,

don,t feed it the berries so hard and choose 2nd gear earlier and you,ll be fine

Hi Guys i have just removed my tail shaft chasing the cause of a clunk and slip in the top end of first gear then it dosent come back again in the other gears middle and final drives look good . the tail shaft housing is full of grease don't think this should be otherwise why would there be a seal in there any one had similar problems
