Regarding the spark plug leads - can you tell me, are both the end caps the same, or is the cap on the magneto end different?  I didn't think to pull them off for replacement so I can't check easily.  I assume from the photos I took that they are the same, but I may be wrong.  I'll see if I can buy the parts and make them up myself on site so that I can run them through the protective tubes.

Pony motor fuel and oil

I would assume that the pony motor expects to run on leaded petrol/gas. Can anyone suggest what is best to feed it?
I am assuming something like 95 RON unleaded with a dose of additive for the valves.

Also, what grade of oil should I be putting in the pony motor? I assume dino or semi-synthetic but what grade? And single or multi-grade? (keeping in mind it's summer here and pretty warm)

Hi, LangdonStevenson.
It's binalong time since I had anything to do with 'em but I THINK the magneto end is a plug-in and the sparkly plug end izza slip-on, allsame car spark plugs - both ends with rubber covers. I do stand to be corrected. If I am right, you would be able to slide the completed leads through the tubes from the sparkly plug end. You could likely slide the magneto end rubber covers on after sliding the leads through the tubes.

Ordinary 30 grade engine oil, non-detergent - again, IF my memory serves me right.

Hope this helps.

Just my 0.02.

Thank you Deas. I have a feeling I should probably try to resurrect the existing leads.  Take some new spark plugs and spark plug ends up with me and see how I go.  That would hopefully be enough to get the pony motor running at least and I can then bring the old leads back and make up new ones.

Ok 30 grade oil unless anyone else says different.

Hi, LangdonStevenson.
Happy hunting.

Just my 0.02.

yes the mag ends push into a socket the plug end clips on like normal automotive leads.

we used delo gold 15w40 in our machine in the main and the pilot. a multi grade is better than a monograde. mineral rather than synthetics. if you use mono use sae 30 or 40.

and yes these older petrols seem to do better with 95 octane rather than normal unleaded and yes a dose of flashlube for the valves. just no ethanol blends in small engines. its okay in the car as you use it all the time.
penrite has a full reconmendation listing in thier mobile app.
 

Thank you Trainzkid88.

I'll just recondition the existing cables for testing then bring them back to make up propper replacements.

OK 15w40 mineral oil for preference. That's handy that both motors like the same oil.

Yeah I refuse to use ethanol blended fuel in anything. I'll have a look at the Penrite app. I wasn't aware of it.

most of the oil companies have thier own app. and it doesnt specify but the book for our machine list the same oil for both so it would work just fine. most diesel oil today are dual service. you would be surpised what a clean with a little shellite or metho will do. dip a cotton bud in some and wipe it on sparingly the residue can be flammable what ever you do dont use petrol around a magneto the residue can cuase them to explode.

I'm getting myself sorted out to go back and attempt starting this dozer in late February and have been working through the Operation and Maintenance Instructions manual (form: 12692-11 for D6 tractor 8U1 - up, 9U1 - up).

What I have discovered is that the manual contains no information about how to check and change the transmission oil. Which is very strange, since the quantity of oil required for the transmission is listed in the Capacities Table in the back of the manual.

From searching around I believe that there is a dipstick and filler for the transmission just in front of the seat? I can't confirm that from my photos unfortunately, so I thought I'd check in with the group and see if anyone can enlighten me.

Drain plug is underneath the machine accessible by crawling under the machine. Not a fun job. Good to loosen it and check for water in the transmission.
The filler is just in front of throttle tower.
Dip stick is just in front of the seat. It does both the transmission and the bevel gear.
I would check for water in the transmission and as long as there is oil in it I would wait until you get the machine going so you can park it so you can access the drain plug easier.
