Removing cam pulley without removing valve cover -1HDT

[albycamel]

This is my first crack at the 1HDT timing belt and water pump. I'll be working outside, so very much prefer to avoid removing the valve cover.

There are lots of great YouTube vids - several of which use an impact gun to remove cam pulley, with a screw driver wedged in to stop the pulley moving. Seems pretty fool proof for removal. But almost certainly movement when re-torque the cam pulley. From what I have seen, most just go a quarter turn anti-clockwise, and then clockwise to re-align timing mark if it moves.

Do most folks just take the shortcut and rattle gun, or follow the FSM and remove the valve cover? I did have a quick search on several forums, but sorry if this is covered elsewhere.

Thanks in advance!

why do you need to remove the cam pulley?

Hi chapel gate. The No 1 camshaft pulley, so that the camshaft oil seal retaining cover can be removed.

why do you need to remove the cam pulley?

you can rattle gun it off and it will barely move. make sure you realign the marks before you remove the belt though.
personally i would remove the rocker cover and brace the cam with a spanner as per FSM. off the top of my head the pulley bolt is 98nm.

you could probable wedge it with a screw driver, and probable rattle gun it back on. it would probable be ok, but im not keen on probable TBH..

Unless you have done loads of cambelt replacements and have acquired sufficient confidence it is best to hold the cam' with a spanner to keep your heartrate down and keep a clear head.
