Speedo

[PatM]

Hi

are 550 clocks/rev counter the same as the 400/4's?

I took my clock apart (again) to try to repair the oddometer/trip and failed- as the gears stripped because the grease went solid on the driven idler gear.
The s/s ring is a bit of a mess now- so I need to re-speedo it, if you follow.

From memory the 550f clocks are larger and the tacho red line is differant.

Dried out lubrication is a killer for these smaller speedometers that have steel gears. I have spares for these speedometers so should be able to repair your existing one. Always have a few good bands and that can be refitted without any evidence it's been apart. I even have new glasses to replace those that are scratched. PM if I can help.

There's a bloke in the VJMC magazine that fixes 400/4 clocks...maybe he's the same person.


There was a nice CB400/4 down at the Gamecock pub in West Kingsdown at the beginning of the month. This is the meeting place of the VJMC & meets every first Thursday of the month. If the weather is dry it may well be that UK Pete & myself will be there this Thursday, as we are both pretty local to Brands.

I've seen 3 or 4 of these speedometers where the plastic gear has stripped, as PAT M pointed out it's due to the grease drying out and becoming hard. These speedometers have been ones where the bike has not been used for some time or where the speedo has been unused for a period. The plastic gear should spin freely on the frame but I've never found one that does until the old grease is removed using a small paintbrush and some turps. There's no doubt that the remaining working life of these instruments will be limited due to lack of lubrication. Even if you find a NOS one that will have been sitting on a shelf for years and the grease will have dried out.

I can provide details of the best method to dismantle/reassemble these instruments, how easy it is to do depends on the capabilities of the owner. However if a tiny clip is lost or something is damaged during the process you may find you need to get another instrument and that might not be so easy.

Yohi823 posting 'might be the same bloke', well it just might be! And a 400f at the Gamecock, well mine has been there on quite a few occasions and might just be there on Thursday!
