1520 Tachometer

[skills4lou]

It turns out the hour meter portion of my tachometer isn't working. I've put probably 15 hrs on it and the hr meter hasn't budged. While doing a little interweb searching, it seems some of the tractors in this series require a little grease on the tachometer drive. Can anyone confirm this, and have pictures? I got an owners manual with it (Jens sales), but it turned out to be for the 1720 and there are definite differences. I have a DC hour meter I'll install to keep track of hours, as $550 for a replacement just for the hour meter isn't really worth it for me. The actual tach works, so I'm guessing the internals have a gear with busted teeth. When I do a partial tear down for reworking the lights (Need to add a couple switches for work lights) I'll take it apart and see what's up. Until then, the little DC meter will keep track for me.

I'm trying to find an actual service manual, but haven't found one yet. Plenty of reproductions, but I've found that those tend to miss things the factory includes and/or have horribly useless pictures.

Thanks!

I own a T1520.
I don't recall reading anything the manual about greasing the hour meter - the meter on my tractor works fine.
I don't know what the differences are between a T1520 and a 1520 are, but there must be some. Last week I purchased an oil filter and was given the filter for the 1520, which was the wrong filter.
When I get a chance to get home I'll look again in the manual to see if there is any mention of greasing the hour meter.

I finally found my roundtoit for this project today. The drive gear for the clock (well, one of them anyway) is stripped out. It may be possible to machine a new one, but I think you'd wind up doing more damage to the rest of the tach getting that one gear out. So, the hour meter will remain electronic.

I took some pics, will upload when I get a chance later.
