1955 Model 640 timing cover removal - help please

[MGBBob80]

Hello all, I'm trying to remove the timing gear cover and am wondering if I need to remove the pulley hub or not. I removed the pulley itself, but the tech manual leads me to believe that I also need to remove the hub and I cannot figure out how to do it. I have not yet broken any of the timing cover bolts free yet in the hopes someone will set me straight. Any ideas highly appreciated. Bob

here's what that cover looks like BEHIND the hub

I really appreciate the look, but don't understand yet though... Look like hub has to come off, but don't see how to do it. Bob

which service manual do you have? and do you have the parts manual? if not, hit the dealers website and go to the parts section for an exploded diagram.

That's a great pic - thanks! Looks like I'll need to use a puller of some sort. Here's a pic of the manual I'm using. Until now I have found it to be pretty thorough. Bob

looks like the old I&T manual.

Yes. Got it with the tractor and have used it ever since. Looking at the drawing you sent - it does not show the nut shown on my pics that I posted earlier. Not sure if that's a big deal or not. I'm learning, but sure wish I knew more about these things right now...:confused3:

Problem solved: 1955 Model 640 timing cover removal - help please

Solution lies in an impact wrench and a 1 & 5/16" socket to turn the nut. The hub then pulls right out. Would not break free with standard ratchet or wrench. Really simple once it was explained, but you know how those things go... Many thanks to Skip's Repair of Whitmore Lake, MI for showing me the way!

it will come out with a standard ratched or wrench.. you just have to blockthe crank... hydro locking a cyl with oil will do it.
