540ixp help

[Ledburyjosh]

Hi.

 

Does anyone know how to remove the sprocket on the 540ixp.

 

I need to stop the aprocket spinning to undo the torx screw. I can't figure a way to clamp it well enough to loosen it.

 

I need to refit the chainbrake spring and get to the oil pump.

 

Thanks

Not something I've had to think about yet, but I own one and and at some point this will be useful info if someone has done it

This isn't something I've had to do so there is no doubt a correct procedure probably requiring a special tool. But, if you're stuck and need it sorting quick you could get an old chain, preferably a blunt one and wrap it around the sprocket. Hopefully you can get it to jam up and undue the torx, a decent pair of leather gloves to protect your hands from the chain would be handy.

 

I've done this in the past on other brands of machine.

As much as I hate to say it, but you clamp the sprocket with a pair of grips to slacken the t27 screw, there was some talk of a tool to hold it but that seems to have not materialised, however behind here is only the pump drive gear, to access the pump you need to split the machine and remove the motor, the pump is housed here, the delivery pipe does take a sharp bend and can collapse stopping oil delivery.

I resorted to grips in the end only to find out what you have said above. The pump is accessed from the other side. it looked like more of a faff than I was up for last night so will set to it another night. 

 

I shall check for bends in the pipe before getting a new pump.

 

Thanks

There will be nothing wrong with the pump, it is similar to the 346/357 pump, so if the drive gear behind the sprocket is ok, then I would be pretty sure the pipe has kinked, it really does take a tight bend to the bar pad, the securing screws for the motor are behind the sprocket so it will have to com off.

OK thanks for the info.

 

I did get down to the motor bolts. The worm gear is all fine, and the pump spline rotated freely. I'll be sure to check the pipe routing
