early Honda wreckers

Post by flexyourhead » Mon Sep 09, 2013 6:05 pm

Hi again.
A new problem has emergef with my bike. I've been in the middle of hooking up a speedo cable to what I'm pretty sure is a'70-'72 Honda CB350 front wheel. Today I've found that the speedo worm drive gear is missing from the hub.
Can anyone recommend a wreckers or some outlet that may be able to help me get my hands on one of these?
Cheers.

You're right Pygmy, Andrew at Puds is the Honda guru and a very helpful bloke too. Also Grant, if ya have no luck with Puds try Eastern again over the next week or two 'cos Paul has a month or so off during winter and would be due back soon I think. Cheers Mark

Update.....
Had an email off Andrew at Puds. It does appear to be a CB 350 hub but unfortunately he can't help me with the part. l have also spoken with Paul at Eastern Motorcycle Wreckers who was of extreme help. He may have one, just got to give him my hub and a couple of days to search for one.
l also spoke with Peter Stevens. They can get me in yhe complete kit for about $109.00. I'll try Paul first but Peter Stevens is looking like a no drama option.

If you can source one in Adelaide, I'm sure someone like me, could post it to ya. Let us know. Speedo drive isn't very big.

Update #2
Boy have the last few weeks been interesting regarding this front wheel and speedo. It is off a 70-72 Honda CB350. I found speedo worm drive gear on Ebay for a CL350only to be told by another person that the CL350 and the CB350 had two different internal hub sizes and it wouldn't fit. A week later another one popped up also off a CL350 but advertised to suit CB350. I took the plunge, bought it and it fits perfectly.

This whole exercise has revealed another problem. On the CB350 the hub sits on the left hand side. When this bike was first built, the wheel was flipped over. As a result the hub is now on the right hand side. No major dramas but because it has been flipped, the speedo worm drive now spins in reverse.
I have spoken to three speedo drive type people and so far I have one of two options.

1/Put a right angle adapter on the back end of the speedo which reverses the drive. Great idea but I can't come out with a R/A adapter. It needs to be coming out straight.

2/ I can get a new face put in the speedo but instead of 1 - 140km left to right, it would be 1 - 140km right to left.The stop pin is repositioned to the right hand side. In other words the speedo kind of works backwards. It would just look weird I guess. Also this option means the odometer works backwards instead of forward.

I like option 1 but is there the same sort of concept available for it in a straight option instead of right angled?

Reading back I'm starting to sway towards option 2!!!

All opinions and thoughts welcomed.

Thanks

That would be my question also. Check to see if the wheel can be flipped back. Even getting a new lug welded on your lower fork legs would be simpler and cheaper than the other suggestions.

Cheaper still is a bicycle speedo. they are small, go up to 150k's, are now wireless and are cheap. More expensive ones are illuminated as well. Legal as far as I know.

If you want to keep stock looking speedo, mount the bicycle speedo inside a stock case with a cutout in the face.

I'd fit it backwards and wind a few thousand kays off the speedo, then fix it........... :shock:

I believe the wheel was flipped as the brake stay bar is attached at the front half of the hub. As a result some sort of bracket would have had to be attached forward of the centre axle and attach somewhere on the LHS rocker (springer forks). Cosmetically it would look atrocious. By flipping it over the brake stay attachment point is behind the centre axle and a small bracket has been made up and attached to the rear of the RHS rocker. It actually works a treat.
I have only come to this conclusion as it was the first thing I tried when I realised the wheel had been flipped. After about ten minutes at looking at what I was up against I realised why it was flipped in the first place.
Having said all that I have just returned from the garage and after actually holding the speedo in place etc, a right angle adapter would work fine depending on how tight of a radius a speedo cable can have before it's too tight for the cable to turn comfortably.
I'll be experimenting tomorrow night with the cordless drill.

Nice advise Prof.

The final update on this topic!
I went to Howards Instruments to try and source the reverse drive angle adaptor. They gave me a web site in the UK to try. I found what I was after but a bit unsure with dimensions etc. I dropped them a line with all dimensions I had etc etc. To date still no reply.
Funny thing is while I was checking out there website again last night there was a link to a page that determines whether you need a reverse drive adaptor or not. I checked it out. I was pleasantly surprised.
Both my speedo and my worm drive both turn in the same direction being clockwise. ie. no reverse drive required. Where I went wrong right from the start was to assume the worm drive was now turning in the wrong direction as the wheel had been flipped leaving the hub on the RHS. Turns out they the worm drive actually turned in an anti clockwise rotation with the wheel in the original position with the hub on the LHS.

So at the end of the day I've just lost about 5 weeks of chasing something I never needed in the first place but now it's full steam ahead again. I'm currently getting a new longer speedo cable made up. After I hook the speedo up it's out for it's maiden run.

Can't wait for that one.

Thanks all for your input.

Very true Prof. I actually hesitated when I wrote it as even though it did add extra time etc onto everything, l did learn a fair bit along the way.
Cheers again.
