Oil pump sprocket removal

All,

 

Trying to remove the oil pump from my tii. Is there a trick to either:

a. Loosening the chain to get the pump off or

b. Removing the sprocket to get the chain off. I don’t want to force it.

 

Tried searching “oil pump sprocket removal” with no real luck. Haynes manual just says “remove the sprocket”

 

TIA

Never mind. Just got it off. Took a little more wiggling and it popped right off

There are two types. One has three bolts and the other has one nut in the center. Either way, remove the fasteners and then remove the sprocket. The center nut version is on a splined shaft. The 3 bolt version is just 3 bolts holding the sprocket to a pressed on flange.

 

Either way is pretty easy.

If you've got the late centre nut version make sure everything is COMPLETELY clean and oil free and locktite it back on when reassembling and then give it enough time to set before starting up. I also take this opportunity to prime the engine with oil by getting an electric screw driver on the pump before the sprocket goes back on - stick the pick up in a bowl of oil and give it a whizz until you've got oil coming out the cam squirter. Saves that horrible long wait for the oil pressure light to go out.

Great trick.  Do you have a similar trick if it's a 3-bolt flange type?

yeah, get a new oil pump with the later single bolt 🙂 I'm sure you could get creative and sort something though
