There is quite a bit of resistance pressing the gears on the cams and then pressing the cams into the bearings (after pressing the bearings into the plate).

Each job for sure is differently.  Was able to use a hand operated press for mine.  Did not press in or out that hard. 

Happy you are done and Bob is happy.

More than .003" and you can mash the gears and take the whole motor out! Check the runout before considering gear drive! HD spec was bumped to .012"!!!

Hoist!

Yea, that's on the gear drive. The chain takes up a lot of runout without any noticeable affects of too much runout, another reason the factory chooses to use chain drive. Also you can have more noise, and can screw up your oil pump if the run out isn't within tolerance with the gear drive. It would kinda be like having an egg shaped gear, could get really tight and then really loose in other spots.

Did not bother checking the pressure, did it by feel.

Years ago I would have just used a hammer and a couple of sockets

Not sure what you mean by standard. I was using a typical hydraulic press. Looked similar to the one pictured below, but ours is a bit older and much better. Like I said I forgot to bring the camera to the shop  I don't particularly care for the press below, the upper beam tends to move around a bit.
Our press has a hydraulic ram bolted to the the upper beam and is fixed. The nose of the ram has a star shaped wheel to make ram length adjustments up to about 6 inches. The press below can get "sloppy" if you are not careful.

There is quite a bit of resistance pressing the gears on the cams and then pressing the cams into the bearings (after pressing the bearings into the plate).

When you do it, take note that there most likely will be shavings from the pressing the need to be cleaned out.

I guess I was asking if there is something unique required of the press - but what you are showing is about what I was figuring on getting.  Gotta shop around for one eventually, have needed one on more the one occasion.  When I used to live on one location for longer then two years I had access to friends - they may even have one in the engine shop on base (now that I think about it, I bet they do).

standard press works?  I don't own one, but have been needing to get a small press for all the other crap I end up wanting it for. 

I use an Arbor Press.....older than my Grandfather and better than anything made today

Bought it for $50 in a garage sale

with an Arbor Press you dont have to pump the cylinder down....in one motion with the handle, the press is accomplished

Nice and smooth in one stroke.

The cam pressing tool on the first post is more important than the type of press, you need to drive both cams in at the same time. Or freeze the cams and warm the bearings/cam plate in the oven, I heard they drop right in most time with this method. Don't personally know anyone that's done it.

That is how we used to replace the ring gears on flywheels.

Yep, I never had to do one, the only car I needed to replace a ring gear on was an automatic, just went to the junk yard got a replacement flex plate.

Hello Boatman,
Nice to see that someone was watching out for my interests. mallets n' all going on during the tear down... Damn it's not easy being a guinea pig for his future surgeries!.... 
For what my opinion is worth, this job, although a little pricey for my pocket book right now, WAS well worth it, just the look on Daune's face  when he rode the final product of his labor was enough. 
Duane was so meticulous and did a really great job, but now he has to wait to tear his down, (freindship is priceless!)....
And I am so impressed with the change in low end performance, and the gears give off such a nice turbo whir.. it is also nice to see my oil pressure up to 45-50 most of the time and even after it's real hot, goes no lower then 15 or so, at least for the 35-40 miles I have put on before going back to salt mine..If I have a concern it would be how rough and "chitty" the hot start is after this work, turns over like rocks are stuck in gears(so to speak), stay calm Duane, it is a price I know I must pay for the outcome) just embarrassing sometimes..
And speaking for Duane AND Myself the parts as recommended by HD-DUDE (Jim) were right on the money,along with his advise and counsel. (Thanks, Metal Dragon inc.)
I also wish to thank all those who threw in their 2 cents, as it made getting er done much easier.. I am riding again and it feels great, Safe Journey to All and maybe I'll see you at Maggie Valley, trying to coordinate work to make the trip w/ Daune,
LTBAWB, Bob

I was looking for link back when we were posting here, came across it today, has a really good write up and pictures of gear drive cam and big bore kit installation and teardown.

Pretty good site but this is a common problem

This account has exceeded it's bandwidth quota and has been temporarily disabled.

That and copyright stuff too.

Does anyone know the reality of the time to replace a cam? I am considering disputing the charge I got of 4+ hours fpr cam, pushrod and Latus spring install while they were doing the head recall. Which by the way I was told is an 8 hour job with the MOCO allowing 5.1 in warranty claim??? I'm thinking I picked up some of that and don't really know.
