Hi Everyone, desperately need some advice please. I stumped.

My d4 6u pony motor seems to be urinating oil somewhere i cannot see.

It losing the lot over 2-3 days, not registering on dip stick. Have checked bolts to make sure the pony is not sneaking off into the bush to pee, its got me buggered trying to work out where it is going.

Thought to ask more knowledgable people if they have had same problem before i get out the heavy weapons of mass deconstruction and try to locate the sneeky little bugger.
One lad suggested it might be the front crankshaft seal leaking into the starter pinion housing.
Any other suggestions or possiblilities?

I will be reading the Manual again in the next few days, when i get it back from a friend (eventually).

Any suggestions would be much appreciated.
Many Thanks and praying for everyone to have a good season.

Regards from Aussie land where trees are given more rights and civil protection than people are .

p.s. Looks like Nth Australia is back on track for old style wet seasons again this year (10 year cycle).Yippee. Cyclone parties.

Yes, the lad is correct:)
Have been known to pee out the front seal and down into the pony clutch compartment and if it doesn't overflow the housing has been known to overtax a worn pinion seal and wind up dribbling into the main clutch housing. Check the main clutch housing drain plug or signs of dribble if it has the cotter pin alteration.

OM, If the front seal were leaking shouldn't there be signs of oil at the base of the pony once it is removed? Mine also lost all it's oil and I have it off for overhaul but I can't see any signs of oil leaking.

Thank you for advice, looks like the weapons will have to be unleashed.

Might try the photo thing, so other forum readers can follow repairs by photo if they have the same issues.

Bloody hot over here at moment. Expecting a big storm hopefully. Need the rain after a bloody long drought.

Hi Sargosailer/aussiematt,
Need to clarify
Engine would have to be running to get oil out of either front or rear seal. With the one quart oil fill the level would not reach these items when sitting.

Sargosailer,
You wouldn't be able to tell. The idler gear section is sealed off by the base gasket and the gear train is splash lubed by the gears with oil supplied from the pony clutch compartment so there is oil flying around in there whenever its running. Key would be to look for sign of overflow or leakage pass the pinion shaft seal into the bellhousing.

If the oil is disappearing while pony is sitting idle the only candidates that would be below the oil level are the drain tube flange, the rear flange and a welch plug in the bottom of the block. The welch plug is surrounded by the flange gasket so if it was cemented on it would be pretty hard to leak out there. Any sign of oil in the main cooling system?

Can't think of any other place it could go without seeing the result.

Thank you Old Magnet,

The oil seems to be leaking out when sitting idle. No evidence anywhere of location of leak.
I think i need to get manual, and step by step track it down.

I might get a longer dip stick to check the true level of the oil.

I've never taken the pony off, and am a little worried about the time required and how many problems i might encounter.

"Stop leak" certainly has not worked, looks like i'll have to knuckle down and work on her.

Any other maintenance i should do while i've got the pony off?

Regards Matt

Most folks miss at least one fastner on the base flange the first time around. Scrape all around the base flange and make sure you get them all.

The only thing under there is the pinion. The pony motor has to be raised up to remove the pinion for repairs, so if you have any problems that adjustment won't take care of, this would be an opportunity to do them.

Generally the gasket is cemented to one surface and a coating of grease applied to the other side so it will release without damage if you have to lift the pony as described above.

aussiematt,
You mentioned dip stick. Could be you are reading wrong oil level.
On your next oil change, drain and fill with 1 quart and check mark on dip stick. Common to see them be off....even worse, on the low side.

Old Magnet,
Thanks for the good explanations. I'm pretty sure my pony oil leaked out while it sat for about 3 months last summer. I'm suspecting the washer seal on the drain tube plug. I appears to be made of lead and doesn't look to be in real good condition. However, I never did see any actual dripping there, just moist with oil.
