Mercruiser 460 Pressure Cap Fitting Replacement

[emmurphy50]

Simple question - anyone replace the actual brass insert (filler hole base) into the coolant reservoir elbow? Bought a new boat and the brass flange the cap twists on to was cracked, now failed, and leaks coolant. I was pleasantly surprised the brass insert (filler hole base) into the cast iron elbow can be replaced (Mercruiser Part #22-13234A-1). Looks simple enough. Anyone tackle this and any tricks to pull the insert (filler hole base) and press the new one in?

Also the sheet in the part kit states to coat with Locktite #35, which appears to be obsolete. What should I use?

Thanks,
Ed Murphy

It is now Red Loctite. If it was put in with Loktite at the factory you have to heat it to remove it. Here is the Loktite tech bulletin: http://www.loctiteproducts.com/tds/T_LKR_RED_tds.pdf. Should be able to put a torch on it and pull and twist it out with a pair of pliers. Let us know how it works out.

Though not the case in here, Mercruiser High Performance did have a model they called 460 which made about 482 HP for the TRS and mercruiser speedmaster series drives back around 1983 - 86.
