520h getting its balls back

[Wheelbearing 49]

When putting the cam gear back on, is it a shrink fit or press on how did you go about it?

I've read two ways to install that gear. One is by heating the gear up with a torch and slipping it on by hand. The other way I saw in a JD Onan manual is to put it in by using a steel tube and threading a screw down the crank shaft. Tightening the screw pushes on the tube and drives the gear back on.

I am interested in seeing which method you use. I am leaning toward the tube method just because of the fact the shrink method unless you are setup to be able to get it on straight before it cools could be challanging. The key word is straight. I have worked in job shops where I have used the heat shrink method and even something that seems idiot proof can go wrong. Not saying the tube method could have it's quirks too. Keep up the good work I'll be watching with interest.

I installed a cam gear last year using the heat method. Heated the

gear with a propane torch, grabbed it with an oven mitt, and it slid right on.

I was suprised how easy it was. Things don't usually happen that way for me.

hummod, if I knew it would work like that I would do that method in a heartbeat. But I have never had the shrink method work that good for me. Now I am not saying that the shrink method is flawed, just for me it has been a problem. There again Murrphy lives at my house and hangs out in my shop. I am sure other members here on RS know him also.

I've shrunk that gear on a couple of times now. Each time I heated it with a propane torch, until I could spit on it and the spit bounced off , and each time the gear slid right on.

I did have the flywheel bolt and a piece of tube right there though, in case the gear "grabbed" before it was all the way on.

The Onan thread on MTF has instructions on how to do it.

I didn't mean to hi-jack the thread, but you guys are very encouraging. Thanks hope wheelbearing here has good luck as you guys did.

If possible, I wouldn't use a torch. Best to use a hot plate. Heats evenly. I have done this many times with cylinder sleeves.

Hey guys got the motor back from the machinist. I'll comment on each picture.

Brand new 0.010 over pistons.

used the wood stove to heat up the gear.

Little valve spring work. 5 on the intake and 13 on the exhaust.

Nice fresh bore

Heres a video of the gear going on easyest thing to install.

Great job for sure! I like that using the wood stove trick! Better than a torch.

To the right side of your bench on the wall what is that thing with a few toggle switches on it? RC controller? Wendys

Polish up thechrome too :banghead:

Looks great! I like the wood stove trick too. I am looking forward to hearing her run for the first time. At this rate, that should be in an hour or so lol :banghead:

Did you work all night or did you wake up early??

[clintonnut 126]

Looks excellent! Especially with the block painted! Looks like brand new aluminum not 20 year old aluminum!

I think louvers in that belt cover would look cool and help with staying cool on that rear cylinder!

[stevebo-(Moderator) 8,034]

How does it run??

[Sparky-(Admin) 19,444]

WOW! All done in ten days? You made very good time as the weather guys in Connecticut are telling us we got a snow storm coming this week. Have you started it yet?

Did ya hit he switch yet?

[AMC RULES 36,941]

Will we get a video of it running too? :banghead:

[Wheelbearing 49]

Yup did the break in today. LIttle trouble with spark yesturday and today. Intermiten getting spark then loosing it. Coil is new from last year. Since I painted the motor I had to remove some paint to get a good ground. plenty of power to coil. So the condensor or trigger could be the problem.

Heres a video or start up.

listened to the video sound on the start up. It doesn't sound that tinny.
