say guys i have recently seen a " cam swap tool" that eleminates the need to remove any of the top end of motor such as intake pushrods and so on. it a thin "sheetmetal cylinder that you grease and slide it in over the cam in the motor, slide the old cam out and slide the new cam in. remove metal sleeve.. has anyone heard of or used such a tool...

 

yeah it's about the same thing as a sky hook or a pipe strecher.

 

or you can use a really long bolt

 

he isn't talking about those camshaft handles.

and as for the topic, that would NEVER work.

the clearence is too tight between the cam and the cam bearings, and what if the lobes aren't the same height as the bearings.....

either way, it won't work. and with a flat tappet cam, you need to change your lifters anyway

 

I dont think the lobes can be taller than the bearings. You wouldnt be able to get the cam past the rear-most lobe.

But gerenally, from all the engines i have seen, SBC and otherwise, the amount of clearance between the cam and bearings is very slim for a sleeving tool.

 

lol, that was about the most retarded thing i've said in awhile, thanks for catching that. I was still waking up this morning when i posted

 

really, tht weird because a guy at scoggin dickey swears up an ddown that it will work.. he even shewed it to me ..its a really thin sleeve thay slides over the cam.. he showed me instructions and all...so is this just a gimmick tool or is there some merit

 

post a link or a pic. there's something like .005 oil clearance between the cam and bearing so that would require the "cam tool" to be around .0015 wall. ever see a .0015 feeler gage?

 

Agreed. .0015" feeler guage is... well... pretty damn thin.
