Topic: Head removal tools

[buffaloejon]

Alright guys, I apologize in advance for asking simple and stupid questions... That I'm sure if I dug through search results for hours I might find, but...

What tools should I need for taking the head off, anything special aside from valve spring compressor and sockets/wrenches?

I just want to make sure I have everything I'll need this weekend when I dig into the head. I've got a couple guys coming to help me that know a heck of a lot about engines, but not about these old gals specifically, so I want to make sure we don't get stuck and then I'm just wasting their time...

What I'm worried about in the shop manual is step 9 in section 3-3 (pg 34) of the CB750 shop manual, where it says "Remove the cylinder". I would assume it means the head, right? I'm not 100% about what to do here... I'm sure I'll end up fine with these guys helping, but I want to make sure there's nothing special to do.

I know I need a haynes or something, but I'm counting on getting HM's book for christmas... And anyway, I don't have time to get it before this weekend.

PS, I know to look for hidden bolts and such, seen enough posts about that!

What not tell us what your intent is? That would help us give you more precise answers.

You don't have to remove the cylinders to remove the head but you'll probably/may want to replace the cylinder base gasket as it's sealing ability may/will be compromised. If this is the case then yes, you will need to remove the cylinders. That takes no additional tools. You do need to remove the cam however because the of cam chain holding the cam which prevents the head from coming off. That'll be the seemingly trickier thing here. Loosen the cam chain adjuster and valve adjusters. Remove the rocker shafts and rocker arms. Remove the caps that hold the cam. Make sure you keep all these parts in the correct place/order as they are matched to position! Take the 2 bolts out of the sprocket before you do the other stuff while it's still held in place and slide the sprocket off it's mounting point on the cam then thread the cam out from the cam chain. A socket or 2 and a wrench is all you need. May need a rubber mallet or similar to bump the head if it's stuck to the cylinders or the cylinders are stuck to the case. Valve spring compressor is not necessary to just remove the head vs taking the head apart. Hope I remembered the correct order. Easy to do, be patient and refer to your manual ALONG WITH those "experienced" friends that haven't done a 750 before. First time may take half the day. Next time 15 - 30 minutes.

My intent is to repair a stripped thread in #3, and go ahead and helicoil 2 and 3 at the same time, to ensure it never happens again...

Thanks for your reply, I ordered a full gasket set from Athena, I've heard its missing a few things, any idea on what else to order?

A basic metric socket set, metric open end/ box wrench set, needlenose pliers set, screw driver set, and don't forget a philip drive impact screw driver. get a complete top end gasket set. Possibly a 6mm helicoil set (exhaust studs have a tendancy to pull out on these old bikes if the engine has been over heated). You should be good to go.

As far as helicoils  go.....I like a product called Timesert which is a solid threaded insert;it's sold in a kit.
