ebinmaine 72,669 #2 Posted December 19, 2020 Best you can do is assume it's original to the tractor which is likely between 65 and 67. Do you have a tractor model number? Just out of curiosity why do you need to know? Share this post Link to post Share on other sites

ebinmaine 72,669 #4 Posted December 19, 2020 If you take the "7235" and pop it in the search at the top of the page it appears the tractor is a 68 or 69 Electro which would have been a 12 horse. The engine should have another smaller tag on it that shows the model or serial number. It's likely gone or you'd have seen it readily. Given that you have a starter/generator it's most likely that your engine is a 65 to 67 or a very early 68. You could put up an ad in our classifieds looking for a manual PTO for a late 60s Charger or Raider and see what happens. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,478 #5 Posted December 19, 2020 There were two crankshaft diameters used back in the day. Some early 10hp engines used a 1" diameter crankshaft and others used 1-1/8" diameter. Pto's that fit will be the same but the inner bearing race between the crankshaft and the pto bell must match the crankshaft diameter. Engine is not original to the tractor because you now have the starter/generator. Keep posting your questions. Garry 1 Share this post Link to post Share on other sites
mrsmart95 1 #6 Posted December 19, 2020 mine is 1-1/8 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,478 #7 Posted December 19, 2020 Most likely the only way to determine the engine size is to remove the head and measure the bore and stroke. Maybe others have a way. If you want to replace the pto clutch you now know all that is required other than the parts list. Garry 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,478 #8 Posted December 19, 2020 Have seen a model and spec number decal on the front of the blower housing top and serial number decal below it. They are not painted over? Share this post Link to post Share on other sites
ZXT 2,401 #9 Posted December 19, 2020 Are you trying to find out the specific information about it to find your PTO parts or just to know? If it's just to find parts, as long as you have a 1-1/8" crank, the HP doesn't matter. Block is the same casting with a different bore. 1 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,478 #13 Posted December 21, 2020 What is the line seen on the pto shaft? Is there a sleeve over the shaft you are measuring? Caliper looks like 1.158". There should be an inner bearing race on the shaft that has an ID of 1.125" and an OD 1.500" This is what the large needle bearing in the pto hub runs on. Is the clutch disc 6.0" OD? 1 Share this post Link to post Share on other sites
RandyLittrell 3,903 #14 Posted December 23, 2020 There does appear to be a sleeve on that shaft and I would also ask if the dial was zeroed on the caliper before you took that measurement? That doesn't look right to me. Randy Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,478 #17 Posted December 24, 2020 Have looked at this picture a 100 times. I could not figure out why the retainer plates were so narrow looking at the blue arrow. Now that the line on the shaft is the keyway looking at the orange arrow retainer one can see it extends past the hole in the plate. One has to look close but it is there. The blue arrow retainer does not appear to extend into the hole. This is the wrong part for an 1-1/8" crankshaft but is a good picture of the groove the retainers fit into.
