| Subject: | Crankshaft Rear Plug for C/S Prop |
I acquired a crankshaft for an O-360 from eBay, it was advertised as
'suitable (convertable) for constant speed prop'. It is a hollow front,
with the front plug in place for fixed pitch service. I'm gearing up to
assembly my engine for my homebuilt project. I was hoping the rear plug
with the socket for the pipe plug was in place. I just removed the
front plug and in fact the aft plug is not there.
I've ordered the plug. SI 1435 just says 'must be installed'. Can
anyone offer my some hints or tips to get it done? Seems pretty
straightforward. The front plug had a tacky sealant around the
perimeter. Would this be required for the rear plug as well? What
product would it be?
The overhaul manual calls for Drift Tool 64770 to install the plug. ACS
lists this tool at $4527. I'm thinking I'll use some thick wall steel
tubing with a groove cut to clear the oil return tube. Can anyone poke
a hole in that plan?
Thanks for any help

That Drift Tool 64770 is designed to install the rear freeze plug and expan
d it to fit very tight in the crankshaft... If the freeze plug comes loose
in flight=2C the prop will go flat because you will loose pressure from the
prop governor and the rpm's will over speed the prop... Very dangerous...
Be careful and don't bend the cross tube on installation...
Try to borrow the proper tool from a local engine builder...

Make sure you have the crankshaft journals acid checked to find out if the
crankshaft has been chromed , if the crankshaft has been chromed do not use
it, it will eventually kill you

Hello Horst
The yellow tag that came with the crankshaft is from EC Services in San
Antonio. The rod and main journals have indeed been ground to undersize
dimensions and been re-nitrided. It appears to have been reworked in
accordance with all approved processes. Would you expect that I'd need
to check for non-spec chrome plating as well?

If the journals have been ground and re chromed because a rod seized up on
one or more journals stay away from the crank , if it was ground to
accommodate a larger shell you are ok !
Have they tested the journals with acid to make sure that it was not
chromed previously ?
I have a friend who had a Glastar on floats , he did purchase a used engine
had the engine overhauled unfortunately they forgot to check the crankshaft
journals with the acid test, at 7000 feet over the mountains in BC the
chrankshaft broke , he crashed upside down into the trees but thanks to the
Glastar steel cage he is still with us

Thanks for the notes Horst, I'll check it out. You are quite right, the
chroming process on chrome-moly alloys does lead to hydrogen
embrittlement. I design oil/gas drilling tools for a living, any parts
that need chrome get a baking process afterward to leach the hydrogen
from the steel. This tag does call out the flange being tin plated and
baked, I presume that's for corrosion protection, and the baking for
hydrogen removal, assuming as well the tin plating has the same issue as
chrome.
I'll check into the process for checking about prior chrome repairs.
