Except the wallet that bad boy is 311 bones! PULLER LINK


I have been following the threads and this project starter as a simple job IE torqueing some exhaust bolts and has grown exponentially!

Others have successfully used a regular Damper puller, the specialty tool is great if you have one however, with a little bit of skill and a quality puller is does not look like an insurmountible problem.
When I perform my cam change I'll pull my Damper without the Spent Moore tool! If I get stuck I will just pull the engine because the 300 bones will get thrown into the Kitty and I'll freshen up the lower end.
Now to put things in perspective I do buy quality tools and have 2 roll aways and a bunch of smaller boxes.

I still say, you pay for what you get, especially, when you talk about tools. When you work flat rate, you can't make money with just ordinary hand tools. Is time worth anything to you? I tried to pull the hub off my LT1 without the Spent-Moore (I like that ) tool, took an afternoon and still no results. Once I got the Spent-Moore, it took 5 minutes. Get to know a mechanic at the Chevy dealer and get him to borrow theirs.

1000% AGREED. Without the Kent Moore tool I will not touch it the hub. Yrs a go we used a puller it a nightmare. Busting knuckle.

Last yrs I borrowed Kent moore tool from a friend to pull the hub. Work awsome. Not a scratch on my hand the hub came out.

I've heard of too many times where someone has broken/damaged things (including the crankshaft) trying to use other pullers.
Sometimes, it is best to buy the right tool because it may be more expensive (after parts are broken) to do it another way.

I know some have successfully used other pullers, but it isn't worth taking the chance.

Well...that's my $.02

I wrench as a hobby and the difference time from my current harmonic damper puller set and the purchase of a 300 bones LT1 specific puller would have to be about 5 to 6 hours before I even thought about it.
(Spent Moore was too easy) Although, if it was made by Snap-On, I may have thought about buying it because I am a Snap-On ***** !

Congratulations!!!

But, this is the reason it isn't worth the hassle to me.

Each person has to decide for himself, but the aggrevation isn't worth it to me. For me, the time involved and the gas could almost pay for the puller.
There have been people that ruined the threads in the snout of the crankshaft trying to pull the hub and found they could not bolt the hub back on after pulling it.

The first time I pulled it, I borrowed the correct puller from a GM dealership, and I liked it so well I bought one. I like the idea that it can be assembled "in place" in that confined area to be used without removing additional parts for room. It is designed to not damage the internal crankshaft threads and it is also a quality hub installer -- it isn't just a puller.

I also bought the LT1/LT4 water pump "seal protector."
That's another one that can be done without the proper tool -- but, it is very difficult to know if you did it correctly or not. Many have unknowingly "flipped" the inner lip of the seal over and had to tear it back apart after finding it leaked.
I actually did do it correctly, but after the aggrevation, I bought one for the next time.


However, they are not cheap.
HINT, HINT, HINT.
I think a good idea would be to have a "loaner tools" section for active paying members of the Corvette Forum.
For the membership, you could put a deposit on the tools and have them sent to you and get your money back when they are returned undamaged.

I ended up tapping the snout on my SCAT crank after a bunch of R&R sessions with the hub and a normal puller.

In the end, I should of just bought the tool.

Great idea Tom I have thought of doing something like this locally.Just some enthusiasts pooling their resources as what happens here on the forum from time to time.

Glad you got it off...

I've been through the process now for the 4th time ( and last time) this month...

I pulled the front end down when I was upgrading my supercharger... sinceI had a few miles on the engine decided to do the water pump, optic and timing set....

Goofed and had the Cam off a tooth,

Put it back together.... cracked a piston... so I pulling it down again LOL

New forged engine on the way....

I have a 8 rib ATI balancer on mine and have to pull the 3 bolts out of the steering box to get enough clearance to pull the balancer off and the hub.... I can't say how much good pullers / installers save time..

I'm getting WAY too fast at this....

What is a waterpump seal protector? Not come across this one, the hub puller yes and the specific puller is a must. I seems like without the seal protector problems could arise, like having to do the thing again. Not a happy thought. Thank you.
