snowy the grey 0 #1 Posted December 29, 2014 Hi all. Probably a basic query really but I am having issues with a not so old Toro transmission filler plug. The machine is a 16/38 which has clearly had a short but very hard life and is now very slow which to me suggests either insufficient transmission fluid or air in the system. Looks like the fluid levels have not been checked for some time. The plug is a hex socket but it appears to be alloy hence when any pressure is put on the key to turn it the metal socket starts to deform. Have tried release fluid but no luck. Thought about heating the plug but as the transmission housing and plug are both alloy I am worried that I may fracture or distort the casing. Any thoughts appreciated.

snowy the grey 0 #3 Posted December 29, 2014 Thanks for the thought. Tried this but approx 2/3 of the plug is in a recess hence cannot get a good grip. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,498 #4 Posted December 30, 2014 What is the model number of this tractor? Suspect the model name is 16-38HXL using a Hydro-gear transmission Was looking to see what type of plug it is but don't know where to look. Wonder if it is a metric key or an SAE key? There might be enough difference to get a tighter fit. Clean out the hex hole, tap the key in to make sure it is bottomed and hit the key with a block of wood to snap it loose.

snowy the grey 0 #5 Posted January 1, 2015 Downloaded the hydraulics manual from Toro which indicates SAE #6 which I do not have as mine are all metric, however may be able to borrow one in a few days time so lets hope it works. Thanks for the thought. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,498 #6 Posted January 2, 2015 SAE #6 sounds like a fitting thread size. Our SAE hex keys are sized by their width in inches like 1/4" etc. the same way the metric hex keys are measured. Garry Share this post Link to post Share on other sites
snowy the grey 0 #7 Posted January 2, 2015 Sorry, as you say this is the thread size should have indicated imperial key required. All mine are metric! Share this post Link to post Share on other sites

snowy the grey 0 #10 Posted January 9, 2015 Combination of hammer, heat and a lot of determination. However has not resolved why it is loosing power at the transmission end! Thanks for your help. Share this post Link to post Share on other sites
