Again, thanks! | | | | Joined: May 2010 Posts: 144 Wrench Fetcher | | Wrench Fetcher Joined: May 2010 Posts: 144 | I have had the transmission and clutch out of my ’53 3600 and have a question regarding reinstalling the clutch. The 48 – 51 Truck Shop Manual with ’52 supplement, says in order to install the clutch, to first “ Hand crank the engine until the “X” mark on the flywheel is at the bottom”. I have looked on all sides of the flywheel and only find marks on the engine side that appear to be timing marks. They are C U then a small o that has a yellow line through it (I take this as TDC) then 5 and then a triangular mark. There is one mark on the transmission side of the flywheel that appears to be an “L” at an angle and fairly close to one of the 9 bolt holes. There is simply no “X” on the flywheel. The manual then says to line up the “X” mark on the clutch housing flange with the “X” on the flywheel. There is a straight mark on the clutch housing flange but no “X”. Does it really matter which way the clutch mounts to the flywheel as long as all 9 bolts are used and secure? (I have a clutch pilot tool) John

You are correct to assume any position is fine as long as the holes line up. They say money can't buy happiness. It can buy old Chevy trucks though.

I just had my 216 engine balanced and all they wanted from the rotating mass was the crank flywheel and damper. Of course the rods, bearings, pistons, pins and rings were statically balanced also. The clutch was rebuilt by a large truck clutch/brake rebuilder in Chicago and I asked about balancing it. They check out the pressure plate and gave it a passing grade, nothing needed to be done to it. I was told that if the PP was not disturbed by disassembly or machining that it would still be in balance. The new disc lining was symmetrical and that disc was balance. In my youth as a parts man I sold many clutches to hot rodders who wound them up way tighter than our Stovebolts will ever go and don’t ever remember any of them being balanced before being installed.

I was suprised that an aftermarket high end pp was out of balance. I know that the 300. Clams spent on balancing was the best $$ spent on that project. Smooth is smooth..... | | |
