Gearbox Oil

[Rick Iverson]

Gents;

I have a fresh GearDaddies LD-200 assembly lubricant only.

I therefore need to provide a lubricant. What’s the deal with this pink “shock-proof” stuff?

I want to do it right on a new GB. May I trouble you for a recommendation, please?

[DaveW]

I've been using this for over 30 years, and my 1994 Staffs trans has never seen anything else. I'm still using my original CWP (ring & pinion). No other issues related to lubrication, either.

What's an LD-19 gearbox? Never heard of that.

I have used Red Line Heavy Shock Proof gear lube for the last 15 years with my V12 March. I am putting nearly 11/2 times the torque the Hewland was designed for through the unit and am using the same R&P, locker, gears and dogs . Years ago Peter Smith from the UK who was a major authority on gear boxes and Hewlands specifically told me this lube was the biggest improvement in lubes he had ever seen. For lesser powered cars probably the lighter version of this would be the choice and yes this lube , heavy or light is the "pink" stuff. It stays stuck on the gears and apparently cushions the loads and from my experience it has saved me thousands of dollars.

Did you ask Scott?

I think he recommends the redline shockproof.

It is a new Hewland GB that is 181 times smaller than a Hewland LD200. That’s my story, and I am sticking to it.

[DaveW]

it is a new hewland gb that is 1/10th the size of a hewland ld200. That’s my story, and i am sticking to it.

And what makes Shock Proof special (different from others), a substantial amount of Calcium! Calcium is considered a detergent when used at much lower amounts. Absolutely no other additives not found in other gear oils. Makes you wonder?

There is significant drag reduction available from lower viscosity oils and lower oil levels (quantities). This is all well researched and found in literature.

I fined it odd that these gearbox specialists are not providing customers with data (choices?) that highlight drag reduction vs wear. Something like this: at this power input, this weight oil provides these many services hours between rebuild/overhaul.

I used the Redline shockproof in a Hewland NST (Swift 008 FA) for a short while, but was destroying gear sets, an old racer came up on one of the occasions I had it all apart in my hands at the track and told me to switch to a regular 75W/90. I drove to the closet store and got Lucas oil and been using that with no issues since, just my experience.

[Jerry Kehoe]

All I can say is my gearbox was designed for 200lbs or torque and I'm pushing 375lbs of torque through it and the R&P, locker and all gears and dogs are perfect after 16 years my conclusion would have to be the lube is working just fine!

I have asked Scott, and Lightweight blue/green stuff was his report. No clue as to what that is, so I thought I would query the base.

Not that I've used it, but that sounds like the Redline Lightweight Shockproof gear oil. If it's that color, that's what he meant.

Redline Lightweight Shockproof gear oil.

This stuff works fine. Clings so well and doesn't stink like regular gear oil.

[Hardingfv32]

A Walmart gear oil product would be fine at the viscosity levels you guys are talking about. The true test of a lubricant is when it is near the limit of its film strength.

You guys could always send me your gearbox internals for Cryo and REM-ISF and then you could stop worrying about wear plus free up about 2% of your Hp loss due to friction.

My gearbox is so polished-in from 28 years of use I think that possible friction loss has mostly disappeared.

a couple of years ago when I was trying to figure out my clutch issues I was talking with Keith Averill (who probably won't chime in since he is a vendor) and he asked what gear lube I intended to use. I told him that in my RP-24 I had always used ATF. His reply was, "have you priced out a new ring and pinion lately?" When he told me how much I think I just said "DOH!"

I asked what he recommended and he suggested Red Line Shockproof, so I had him send me a couple of quarts and that it what is in the Lola now.

I tend to have a high degree of mechanical sympathy (comes from driving worn out junk over the years) but most drivers are a bit harder on equipment and can likely benefit from the additional protection Red Line offers.

YMMV

Dave, do you add zinc to your box?

No, just the Valvoline VV975 75W90 synthetic right out of the bottle.
