fast88pu 3,313 #1 Posted May 24, 2015 This may be a good or stupid question. But how do you fill it with oil ? The plug on the back left side is down too low for enough oil to get up to the wheel bearings. Any help would be great Share this post Link to post Share on other sites
Terry M-(Moderator) 2,126 #2 Posted May 24, 2015 (edited) Good Question....That plug on the rear lower left side is the fill and level plug from what I know. I believe what happens is when the trans is working/turning , oil is being "distributed" around internally by the gears spinning through the gear lube.

fast88pu 3,313 #3 Posted May 24, 2015 ok tank you. Think ill play it safe and over fill it Share this post Link to post Share on other sites
rmaynard 14,916 #4 Posted May 24, 2015 Fill it through the shifter hole. Your transmission requires 2 quarts of fluid and filling it by way of the plug on the side will leave you about 10 oz. shy. Share this post Link to post Share on other sites
Racinbob 10,299 #5 Posted May 24, 2015 I don't think it would be a good idea to over fill it. The upper gears, etc. depend on lube being 'splashed' on them' I discussed this with Stevasaurus a while back and he's actually seen the amount that gets tossed around. Overfilling could possibly limit the splashing effect. Filling as recommended will be just fine. 2 Share this post Link to post Share on other sites
pfrederi 17,157 #6 Posted May 25, 2015 Unless it is really hot 90w gear oil and splashing are not words used together very often. It is heavy sticky stuff picked up by the gears and spread around.... Share this post Link to post Share on other sites
Racinbob 10,299 #7 Posted May 25, 2015 I thought the very same thing Paul until I was proven wrong. I'm sure a lot is carried up but with the speed of some of the gears it creates an oil hurricane. Share this post Link to post Share on other sites
stevasaurus 22,234 #8 Posted May 25, 2015 If anyone does not believe that those gears throw oil...put the trans on a work bench with either an electric motor (I use a 1/3 hsp with a rheostat so the speed is close to correct)) or with a figure eighted fan belt off the drive pulley of another horse and look down the shifter hole with a flash light. It is like it is raining in there and that is the only way the shift rail shafts and detente parts get oil. 2 Share this post Link to post Share on other sites
fast88pu 3,313 #9 Posted May 25, 2015 Makes sense then . Does anyone know the oe part # for the drive belt to a 68 lawn ranger or the size ? thanks Share this post Link to post Share on other sites
stevasaurus 22,234 #10 Posted May 25, 2015 If this is your horse...model 1-1631? Belt # 1576 from TORO. Click on this link for the manual...http://www.wheelhorseforum.com/files/file/808-tractor-1968-lawn-ranger-da-om-ipl-wiringpdf/ Share this post Link to post Share on other sites

rmaynard 14,916 #12 Posted May 25, 2015 Two quarts is not overfilling it. Two quarts is the amount recommended by the people that manufactured the transmission. I tend to agree with Paul on this one. When the temperature of the outside air, as well as the 90-140 gear lube inside the transmission is at zero degrees or lower, I don't think there is a lot of slinging going on. Two quarts of oil insures that all critical parts are covered with adequate lube to keep it running.Many transmissions that are not serviced regularly and are let out in the weather not only have two quarts of oil, but another pint or so of water. I have drained as much as 2-1/2 quarts of muck from a uni-drive only to have it perform flawlessly after flushing and refilling with the prescribed type and amount of oil.As I said, I would pull the shifter, put in two quarts, install a new shifter boot and be done with it.

stevasaurus 22,234 #13 Posted May 25, 2015 Bob Maynard, I think you need to start to re-read what was said in these posts. I was not going to fight with you over the 2 quart thing and the fill plug. You are entitled to your opinion and I am tired of hearing it. I was referring to fast88pu saying that he would just over fill it then and think he was safe... and Bob telling him not to do that, and why. Completely different from what you were saying. You seem to be looking for a conflict, not going to get one from me. BTW, the transmissions that I were testing were done in the winter...the gears do throw oil. Unless you think I am lying about that...check it out If you want to know something...I have no proof that filling up a Uni-Drive all the way would be harmful...that is just my observation. 1 Share this post Link to post Share on other sites

If you are tired of hearing my opinion, then by all means exercise your option to place me on your "ignore list". 1 Share this post Link to post Share on other sites
