I Currently have X9 10 speed rear, but need to replace jockey wheels. are these interchangable with X10 or XX?

Replacing jockey wheels is one of the easier tasks on a bike. You will two standard, 11 tooth jockey wheels. Investing in metal ones with ball bearings is a good idea. Use an aallen key to remove and replace one at a time, taking particular attention to the way the CHAIN goes around each jockey wheel.

Blade engagement lever won't disengage

If this is a manual engagment system all the lever does is to pull a jockey wheel into the back of the belt to tention it thus starting the blades to turn, so either the cable is jammed that pulls the jockey wheel in, or the jockey wheel arm is seized and needs freeing off to allow the jockey to to move to the relaxed position.

Steering wheel not centred when driving in straight ahead.

2 ways to resolve. Take steering wheel off and recenter on spline ( done by dealer or auto electrician due to air bag) , or do a wheel alignment adjusting tie rod ends same distance as each other ie move both wheels left to right or vice versa.

Need to pull the ignition relay switch does it pull straight up without any hidden locking devices

Hello, Most of the modern Ignition switches are 2 piece with the lock core being removable. The Ignition switch has a spring loaded pin used to release the core. The plastic steering column covers have an access hole underneath the Ignition switch and you can use a large nail or drill bit to press and release the core.

Plan on disconnecting and reconnecting 1 battery cable so you can position the core in either the ACC or RUN position for removal. Some Ignition switches have adjustments to align the safety Interlock controls. You need to scribe a mark on the shift column frame before removing the old one so you can reposition the new switch in the same spot.

Some installations require jockeying around the tilt wheel to get clearance for the plastic cover to drop. I hope you find my solution very helpful.

My chain snapped and I fixed that. But exactly how is the chain threaded through the Shimano rear derailleur? What is the correct path over and under the 2 jockey wheels? I cannot find a diagram that shows...

It will entail taking the chain apart again (known as "breaking" the chain).
The chain feeds UNDER the lower cog on the derailleur, BETWEEN the 2 cogs, and OVER the top one... then BEHIND the gear cluster and back OVER it. Run the other end AROUND the front chainwheels, through the front derailleur and re-connect. You may find it helpful to lay the bike on its side (sprockets up) and have someone hold rear derailleur to keep tension off the chain.e86da85.jpg
Good luck to you.

Took the jockey wheels off and cleaned it all, but now after refitting the jockey wheels the lower arm has no tension causing the chain to hang low and slack. What have I missed when refitting the jockey...

Did you also remove the derailleur from the bike to do this? When you put it back on there's a tension screw that normally sits on a flat tab or portion of the right dropout to keep the entire assembly rotated toward the rear of the bike.

Or just go here. Pictures speak louder than words.
