Final Drive Gear Oil Volume Discrepancy 2007-2008

Post by Desantnik-VDV » Fri Dec 06, 2019 6:45 pm

I remember 1999 and 2002 models final drive had 3.5 oz or 105 mL volume, while 2WD Gear Up and Patrol later years had 4.5 oz or 135 mL.
Now for first time I am changing gear oil on a 2WD Ural (2007 Gear up). Measured with postal scale exactly 4.5 oz and filled the final drive and it shows about 1/2 inch above the full line on the dipstick (screwed in). I doubt bit there might be some of old oil leftover (undrained).

There is a mistake/discrepancy in 2007 and 2008 manuals. 3.5 oz = 105mL and 4.5 oz must be 135 ml.

I don't know how much it will throw you off but since oil is a lower specific gravity than water, the oil volume will be greater than the fluid ounces for water.
I use a basting syringe to get the proper fluid ounces, not weight.
I may not be good, but I'm slow.

I noticed that little discrepancy in my manual too :lol: I usually overfill mine a bit and let the excess blow out the vent until it finds it's happy level (the lower line on the dipstick when screwed in)

I didn't check any other years but cross-referenced my 2007 to 2008. Other years may be affected as well. I don't want it to puke on a new wheel :D I will let out a little and level it with the top mark of the dipstick.
I had to flush all oils on this new to me NOS 07 Gear Up, with 32 kilometers which sat in the storage for 12 long years. The worst was the gear oil. It was black and very thic. I had to flush it a few times. I may drive some 50-100 miles and then change all oils/filter again.

I’ve always put in 135ml. We’ve got the same FD, I believe without the breather. Press on and enjoy the ride.

It's the old style. There are three holes inside the filler bolt (dipstick top) and it has a plastic cap pictured.

There are other threads on this topic, one of which I taught me that running a bit less than stated in the manual, might be a good idea. My one wheel drive, is much happier, and cleaner, with 90 ml in the final drive, rather than the recommended 105 ml.

You can get a plastic syringe in a 100 ml or so size, at many places....TSC, Walmart, etc.

My Owners Manual disintegrated long ago. It also had the dreaded completely wrong torque spec for the head bolts as well so good riddance.
Many an owner and even inexperienced dealers unfortunately found out the hard way.

Before it was completely gone I "P-Touched" all the mundane information onto the inside of the truck lid (also my phone).
Comes in handy when you are working on regular maintenance stuff rather than flipping pages of a book.

Fancy and/or fantastical brands of fluids of course are an owners preference:

If you look on page 61 of the owners manual it has a list of recommended lubricants and that has the correct 3.5 oz./105ml and 4.5oz./135ml amounts.

I too find a bit less than 135ml works well in my 2010 Gear Up.

Best,

Finally finished refurbishing this 2007 Gear Up. Cleaned the gas tank (did not paint the tank insides per your recommendation Jeff), new fuel lines, filters, carbs cleaning. Installed new manual petcock, quick disconnect with shut off for tank crossover, installed raceaway heat shields between head and intake manifold compliance fittings, new crankcase to airbox curved hose instead of that old thick piece of straight hose. Installed my trusted new Yuasa 310 cold cranking amp battery YTX20HL-BS (YUAM620BH). Changed engine, gearbox and FD fluids. Napa autoparts 20w50 SAE oil (will flash it at 100 km and put Castrol 4T 20w50) and Castrol 80/90 Gear oil...
Valves clearances were too tight (could not even get 0.002 gauge in... set them at 0.003, checked timing, air/fuel mixture 2 turns out, good running at idle and got revs ok (not lean, not coughing).

2007 NOS Gear Up has now resurrected :clap:
She is a VIRGIN. Old but still virgin :D
"Twinmax'ed" it and did some 6 km up and down my street block. It now shows 38 kilometers on odo :boogie:

It took me 6 days of working and waiting for various parts deliveries. Now waiting for tachometer delivery and installation. Need fine RPM tuning and my first test drive next Saturday or Sunday, after which I will change all fluids again.

I posted this for visually, for other to be careful.
I am using the PDF version of the manual.

Many years ago up to 2007 when I had Urals I was using kitchen measurement cup and going exactly for the book said 105 ml. After poring all into the FD there was still some 10-15 ml left on the walls of the measurement cup. So, yes about 90-95 ml is good for a single WD FD.

I'LL QUESTION. POSTAL SCALE ? :?:
The 3 times I've changed my final drive "lubricant" has been measured in fluid ounces. 3.5 the first and third change. No problem. The one time I put 4.5 ounces in, some blew out the upper fill breather cap.

:cheers:
Is 1 fluid ounce = 1 ounce, volume = weight. Some liquids are more dense and heavy... An inch more, an inch less...what's the difference? :D
1quart is 946 ml, which is about 2 pounds. I am used to metric system like Urals in kilometers. See what you see on odo, then do the math. :lol:

135 ml gear oil, use marks on dip stick. If too much oil it will 'puke out', not a problem.
