Stuck Speedometer Repair Pictures

[3Phase]

My 1980 XS1100G Standard speedometer was sticky and the needle was broken so I had to fix it.



I found a broken 1978 XS1100E instrument cluster in the junkyard but I repaired the 85 mph speedometer first for practice and photographs






Disassembly:

Faceplate Removed




I managed to save the speedometer gasket




I broke the turn signal self-cancel reed switch




Mark the speedometer driven wheel and fixed housing before you remove the needle




Look for grease between wheels and the housing

Grease buildup between the wheels and the housing caused this speedometer to stick






Check the spring for grease or dirt




I have to thank TopCatGR58 for this special speedometer needle removal tool




Disassemble the faceplate to clean it




Lightly grease all odometer gears




Assembly:

Put the speedometer back in the housing




Put on the faceplate






Re-crimp the faceplate retainer ring












Install the odometer trip reset knob





Install the turn signal cancel reed switch





Replace the gasket and put thespeedometer in the bucket







Put the Speedometer back in the instrument cluster





The instrument cluster is back on the bike and I have a working speedometer!

Well done Scott. Could you possible expand a bit on the early stages of this - i.e your technique for getting the case "uncrimped" for the repair?

No problem, Ken.

I had to re-shoot everything with a regular digital camera so I lost some details.

For some peculiar reason the original shots I made with my mobile phone camera looked really good on the phone's display but...



I'll try to get the detail for the faceplate ring and trip reset knob removal tomorrow. The reset knob was actually more difficult to remove than the faceplate.

Speedometer Disassembly

My 1980 XS1100G Standard speedometer was sticky and the needle was broken so I had to fix it.



I found a broken 1978 XS1100E instrument cluster in the junkyard but I repaired the 85 mph speedometer first for practice and photographs




Disassembly:

Remove the speedometer from the bucket




Faceplate Removal

Use a small screwdriver or other suitable implement to uncrimp the corners of the faceplate



Pry the middle edges away from the speedometer housing



Gently lever the faceplate off of the speedometer housing



Faceplate Removed




Faceplate Gasket Removal

Remove the faceplate gasket and the turn signal self-cancel reed switch from the speedometer housing. Gently pull the gasket off and over the odometer reset knob. I managed to save the speedometer gasket




I broke the turn signal self-cancel reed switch





Gasket removed



Remove the odometer trip reset knob by turning it clockwise. If it will not unscrew, use needlenose pliers or a hemostat to gently hold the reset shaft but be careful not to bend the face






Needle Removal and Inspection

Mark the speedometer driven wheel and fixed housing before you remove the needle



I have to thank TopCatGR58 for this special speedometer needle removal tool




Look for grease between magnetic drive wheel and the driven wheel and the housing

Grease buildup between the wheels and the housing caused this speedometer to stick and the indicated spead to read slower than normal






Check the spring for grease or dirt
Do NOT bend the spring!




Disassemble the faceplate to clean it




Lightly grease all odometer gears

The edges are crimped evenly








Install the odometer trip reset knob by turning it counter-clockwise until it is fully seated

Put the speedometer back in the instrument cluster





The instrument cluster is back on the bike and I have a working speedometer!

Thread cleanup?

I can't delete the original post, but I've added some extra pictures. I had to split the new post in half because the forum software told me I had too many images linked.

Is there some way I can remove my original post?
