Tach Reduction box

Post by mgtc0604 » Fri Apr 27, 2018 12:00 pm

I am in the midst of cleaning and refurbishing my tac reduction box.  Some idiot (me) loaded it with chassis grease and it (thankfully) managed to work itself off the generator; else I suspect the would be nice shiny nubs where the gear teeth once meshed.

 

My stupidity aside, does anyone have a recommendation for the “gear oil” the Book notes?  And any other thoughts?

 

Many Thanks,

 

_Peter

I use #90 or #140 EP gear oil, same STEERING BIX, GARBOX AND DIFFERENTIAL.

Don’t forget a few drops of engine oil in the generator rear lubricator .

As there is no gasket on that thing , I think oil will cover the engine bay Joe Curto 718-762-7878 www.joecurto.com -----Original Message----- From: mgtc@comcast.net [mg-tabc]

Joe,

 

The Penright stuff is a viscous oil that seems light enough for the reduction gears, yet thick enough not to leak. I have been using it in my steering box with no problems .and no leaks!

 

I understand you attended a shop day at Abingdon Spares last week. My ace mechanic, Jim Vibert, was there and said hello to you. He appreciated the session on SU dampers.

I am in the midst of cleaning and refurbishing my tac reduction box.  Some idiot (me) loaded it with chassis grease and it (thankfully) managed to work itself off the generator; else I suspect the would be nice shiny nubs where the gear teeth once meshed.

 

My stupidity aside, does anyone have a recommendation for the gear oil the Book notes?  And any other thoughts?

 

Many Thanks,

Joe, I didn't use oil because I thought it would leak. I ended up using lithium grease because of it's water and high heat resistance.

Pessimist…or simply being realistic?  I’ll let you know.

I put a NOS unit into my TC several years ago and decided to try 600W gear oil as used in Model T rear ends. It's really more like a 250W, maybe 320W by modern standards. It hasn't leaked and the unit is still in perfect running order. So far so good. - Steve Simmons, TC8975 -----Original Message----- From: mgtc@comcast.net [mg-tabc] mg-tabc-noreply@yahoogroups.com> To: mg-tabc mg-tabc@yahoogroups.com> Sent: Fri, Apr 27, 2018 3:00 pm Subject: [mg-tabc] Tach Reduction box I am in the midst of cleaning and refurbishing my tac reduction box.
