Well-known Member
i know, some will say, another same old questions,, o-k, i changed the plugs finally, [autolite 386], new fuel, almost a gallon anti-freeze, i"m getting it ready for the stock-show parade in denver, colo. thursday,, so when i"m done and the next thing is the oil,,now is there a filter in the bottom when i take it a part, or what am i looking for to do...bob
 
Use 10W/30 oil it is better for cold conditions and an oil for a diesel is not suitable as it contains detergent additives which will loosen all the crud inside and it will be carried around through the Pump etc. and will cause some wear. Use low detergent Multi-grade 10W/30 as used in a gas engine..John(UK) [email protected]
 
There is a filter in the oil pan above the round plate. You may have trouble getting the plate to seal again if it has been damaged by hitting something. Always use a new seal on the plate. If you want more information about changing the filter, email e at the address below and tell me what you need and I will send it....John(UK)[email protected]
 
(quoted from post at 17:35:46 01/10/13) thanks john, should i just change oil and leave filter alone, is it just a wire or paper filter..


I would change the filter. It's just a paper cartridge style filter. If the filter housing comes out make sure you put it and the spring and stuff back in the right order or it will be pointless to have an oil filter, or the spring could be missing because sometimes people loose them and don't replace them. Make sure to check it out. Here is a pic of the assembly.

Change the filter every other oil change, if you don't know when the oil filter was last changed then change it and then you will know for sure.
The oil should be changed every 150 hours. Take a note how it all assembles, Jason has sent a picture for you to follow. Make sure that the "O" rings and felt seals are in good order, fit new ones if necessary, don't take any chances. It is a paper type filter with a wire mesh internally and the whole thing is in a perforated steel can. The filter should be an inside to outside filter or it will not clean the oil properly.
If you don't have an instruction Book for your tractor, just email me at the address below and I will send you a copy..John(UK)[email protected]
 
I would mark the round plate in order to place it back in its original position as most times both the pan and cover have incountered a rock.
 
Jason: thanks for posting that diagram - I have the Parts Book for the TO-20, but the print job in mine isn't nearly as good as yours. (Looks like your book must be an original.)

I'm waiting until snow blading season is over to change my oil and filter for the first time, and I'm curious to see what parts have been lost out of my assembly. (The tractor seems to have been fairly well maintained otherwise, so hopefully I won't find any big surprises.)

One question: where does the felt washer shown as Reference No. 53 go?

And, does the No. 48 Spring come out when changing the filter, or does the No 49 felt washer (assuming it's there) hold the spring in place?

Finally, as has been discussed in great detail elsewhere on this forum (including by me), I have three (3) different oil filters that are ALL allegedly the correct filter for the TO-20, and I'm still not certain that any of them is correct!

It appears that many sellers/manufacturers are ignoring the "inside-to-outside" flow requirement for the TO-20 filter, as mentioned above by John (UK), and as discussed in the TO-20 Owner's Manual and Shop Manual, and are selling the same filter for both the TO-20 and TO-30.
 
thanks everyone, parade went well, tractor never missed a beat, purred like a kitten,, that diagram will help, will take all advices on what to do, now i will get/find a filter and attemp to change when it gets little warmer, don't have garage to change in,,[too much junk, storage,lol] being don't use tractor except for shows, parades....
