Hey everyone,
I'd like to install an Andrews 37G gear drive cam, adj pushrods and lifters. Is this a difficult job? I do most of the maintenance on my 05 EGS. I have never
attempted tearing down a motor but the deepest I've gone was change my inner primary. I don't have an Indy and my dealership sucks. I have the tools I think and have access to a press. I also read the service manual but it's a little confusing. A friend of mine said "If you screw up there's nothing that can't be fixed"....but then again he has the dealership change his oil.

Should I go for it?

 

bazam9s, it's not as hard as you think. I put gear driven cams in my '01 ultra last winter and it kicked 92 hp and 97lb torque, Crane 310-2, all with 39,000 miles on the clock. I found a website www.harleyhog.co.uk that has great graphics and walks you through it step by step. That along with the service manual, patience and attention to detail you should be able to do this.

I had an Indy set up the cam plate for me with the inner gears and pressing in the bearings and cams. I would think your local dealer would do that for you for a price that I think was worth the expense. There are other obstacles, removing and installing inner cam bearings, aligning the oil pump, push-rod adjustment (get new lifters) and others but not so scary. Step by step and a good torque wrench. I found Harley Tech Talk on AOL and for 80 some bucks I bought a inner cam bearing puller/installer and in five minutes had that done.

Just to let you know I THINK the dealers charge 4 or 5 hours to do the swap so, again, that's something to consider. I just bought a '08 ultra and the dealer would give me nothing for the cams so I took them out on a Saturday morning and installed the chain drives before trading it in. I had the advantage of a cam plate I bought off of ebay with the stock cams and inner chain intact so I just had to buy a couple of new shoes for it. But if you got into the compensator nut and clutch setup with the inner primary work I don't think this is beyond your capability.

Plus the advantage of living in Massachusetts, long winter, take your time and ask for help if or when you need it.

 

You can do it Bazam, get the manual, do your homework, get a few tools, and take your time. But the service manual is a must.

Good luck

 

Have you looked into the Andrews conversion kit? It's really all H-D parts except the cams. It's a good alternative if your runout is a bit excessive. I've been running the conversion with the 26N cams for 12k miles and am very pleased. It boosted the oil pressure and eliminated the bad tensioners. Be sure to check the runout before you buy the gear drive. It's not too difficult, plenty of help available online if needed. Good luck.

 

The JIMS tools are great for this. The inner cam bearing tools are almost a must. The fixture to hold the cams in line when pressing them into the cam plate is also something I wouldn't want to do without. A good press is also a must. Before you install the cams check your pinion shaft run out with a dial indicator. Should be .002 or less. If it exceeds that, go with the Andrews kit to go to the newer style hydraulic tensioners. Andrews gear drive cams come with detailed instructions. Alignment of the oil pump is covered in the instructions. No special tools needed, but some guys use Evo lifter block alignment tools in 2 offset bolt holes to align.

 

The bike only has 5500 miles on it...is it safe to say that the runout is tight, of should I still check t be sure?

 

If you have access to a dial indicator i would check it.It will Give you piece of mind knowing what your run out is

 

Thanks guys, yes it sounds like a winter project. Here in MA The good weather is short, so I think I'll attempt this then. Thanks again...

 

Nope they can be over spec brand new. Check it. It's the only way to know if your motor is a candidate for geardrives. You don't want the gears running tight at one point and loose 180 degrees later.

 

What do you plan on using for a fuel management?
