Colt Case Ingersoll Garden Tractors

On some Onan oil pans I have noticed along with the oil drain location is another 1/2" NPT. pipe plug at the base of the dip stick tube which can be used to drain the oil leaving the original drain open for one of these .

That’s neat.

Are those built for submersion in oil, or coolant?
I sure wouldn't mind warmer oil to start off with in this weather. I suppose I could just change to winter oil, but my tractors don't see enough hours in a year to justify 1 change, let alone 2...

Well Dave you really had me going here. I thought oh man, this is perfect. I would really like to not have to cold start Ingy, not that it can't be done, but you know.
So I checked tonight and I don't have an extra drain on my P218 and the oil drain is only 3/8".

Well That sucks . This is a pic. from the net of a pan that looks just like the one I have .

Notice the drain hole in the top left thats 1/2" npt. . Now notice at the base of the dip stick tube , that cross hole goes through and has a 1/2"npt plug in it now but can be the new drain while the old drain is used for the heater. My P220 in Frankie doe not have it either but I need to pull the engine and reseal this summer , at that time I plan to change the pan to one of these .

Dave

I did a little looking last night and I did find that Katz has one with 3/8" thread but that one doesn't mention it's for oil. I also found a review from someone who used the 1/2" with fittings, bushing it down to 3/8" on a Briggs.

So now I'm back on board, what would be wrong with just taking it in and out when changing oil?

Add a stick-on heater on the oil tank and now we're cooking.

See if you can find another pan like the one you have on it cheap and see if you can open it up to 1/2 " Npt . and like you say the heater is then the plug . Heck then really only need it in place for the winter . And with the stick on heater .

I could drill out and re-tapp the hole, but if the heat probe fits, I can just put a 3/8" nipple and a 3/8" x 1/2" reducing coupling in and done.

@Timj right side / dip stick side of pan I have .
Depending how thing work out I may put the heater in the base of the dip stick and leave the drain as is if it works out .

I think I would do it that way too.
As long as it doesn't interfere with the dipstick.

You don't want anything to interfere with your dipstick! especially something very hot!

Synthetic oil has a more stable viscosity with temperature variations compared to conventional oil and will flow better at low temps allowing for easier winter starts. I'm not sure if you guys are already running synthetic oil. Just throwing this info out there.

I have 5w30 full synthetic in the Onan, but reg 15w40 rotella in the hydraulics. The synthetic definitely helps, started at 2°f a couple weeks ago, but it would make me feel better if I could plug it in for a little while.

I also run 5W30 full synthetic in my Vanguard. In my hydraulic system I am running 5W40 full synthetic year round. Got tired of changing it spring and fall. Seems to work just fine with my Hydravac in the summer despite discussions on the old forum saying it doesn't. I did top it off with a quart of 20W50 full synthetic last summer. My tractor starts just fine in the winter especially with the new 350CCA battery but it's also around 20°F in my attached garage.

Ingersoll 4016 cold start video. Sorry its not an Onan...

@MattA here's my Onan B43M in a 226 that I sold at -14C/7F after sitting for a week. That tractor always started on a dime.

90% percent of engine ware is during cold start up unless it runs low . If I can better protect it by warming it up a bit before using it , I feel better about it . I know I feel better being warmed up before working

That's my exact thought Dave, go plug in, couple cups of coffee while warming up.
I can already see the toll the cold starts are having on the hydraulic hoses. Most of the low pressure hydraulic lines on 4118 have started weeping and dripping this winter. Being 30years old has nothing to do with it.

Dredging this old thread up, tis the season and it's been on my list for a while but I'm so far behind on my list. @DavidBarkey did put one of these in? Just checking before I order one.

Not yet @Timj , I have not got back to the 446 Blower tractor build . I hope to be next week .
I will be uploading progress reports as when I do .
