    Default Bowl Bushing...

    I'm trying to replace the bowl bushings in a berk jg during the rebuild. One of the bushing falls right through the bowl (zero tension to hold it in place) What is the fix for this? Thanks

    If indeed its a new bushing and simply pushes in with zero resistance the bushing bore is either worn (prior spun bushing) , corroded and too large after clean up , or least likely cracked truthfully too loose as you probably have calculated is not good , you could try clean up everything (degrease) and try some bearing/sleeve locker (loctite etc) as a temporary repair but honestly the bowl probably needs line bore and sleeving or replacemnet call if you need help Tom

    Yeah they are everywhere but I JUST had this powder coated. I believe I can repair this one for the cost of another and recoating.

    The Locktite green sleeve retainer is pretty stout stuff. May be worth a try. Make sure surface is really clean. I've used it with success a couple times in other non marine related apps, but never tried it on a bowl bushing.

    Here's another product I've never used by might work if you have more than .007 clearance the sleeve retainer is limited to... looks like it goes to .020" http://www.permatex.com/products/Aut...rn_Parts_b.htm

    Not sure which end is loose but, if you can angle-in a 'punch' and give it a few wacks you may be able to displace some material and make the bushing a snugger fit (understand?) > that with the Green Loctite may be all you need.

    if the current forward bushing bore (which) seems loose to you is not eccentric or worn vs the bowl bore center line then you may be alright with locker and or peening/knurling etc however given the very close clearance tolerances between bushings and shaft at play here the repaired bushing has to be nuts on center, aligned with not only the rear bore but also square to the bowl flange & register if you repair it suggest you loosen your packings and roll it thru by hand checking for tight or "sticky spots" Tom

    Default Bushing

    Easy fix, have it line bored and put a dominator sleeve and bushing in it. That way you can do away with the oil as a lubricant and just use water as the coolant like dominator does. Don't run in dry though. You can tap the end and cap it so you can grease it as an option too.
