Topic tags/keywords: planer

I have a 1989 Mastercraft Pro 12” planer that I bought from an auction website. It worked on arrival but now needs a new belt, and I am stumped.

I have removed the housing from the side where the belt goes. The two pulleys do not seem to be adjustable such that you could move one, slide on the belt, and then increase tension on the pulley until the belt was in the right spot (at least to my untrained eye). I do not have, and do not seem to be able to find on the internet, an owners manual for the machine.

If anyone knows how to do this, or has suggestions on how planer belts typically are installed, please let me know. Thanks.

Rob

If it takes a v-belt you can usually find a link belt that will work. Link
belts are touted for reducing vibration, but additionally they may be
easily installed in such awkward situations as you’ve encountered
with your planer.

Thanks Loren. It came with a 1/2 inch wide flat rubber or rubber like belt. When it broke, I bought some link belt at Woodcraft (@ $9 a foot – http://www.woodcraft.com/Family/2020051/Power-Twist-Link-Belt.aspx ), and matched it up as best I could around the pulleys. Turned on the machine, and all heck broke loose – smoke, noise – melted a good bit of the belt because it was too loose. Before I invest in more link belt, I have to figure out how to adjust the pulleys, or get a flexible flat belt and jam it on somehow.

If you have 2 pulleys that don’t move, is there an idler in the system somewhere that provides the tension on the belt?

Not sure I’d know it if I saw it. Can you tell me what I should be looking for?

That’s probably a high-speed planer. I should have thought of
that. You’ll be looking, probably, at a belt (possibly red colored)
that’s flat on one side and sort of segmented on the other.

I’m sure you won’t find a manual for your planer, but these
things all come out of a few factories and the designs are pretty
similar at heart. I changed a drive belt on a Dewalt 733 once
and I don’t remember it being a big hassle, but I did have to
take some stuff apart as changing the belt wasn’t really considered
a self-maintenance item.

A schematic from a similar planer from the same general date
of manufacture will probably give you some insight about how and
what to disassemble to get at the belt.

One thing you can try is determine the size belt you need, then
search through tool parts sites to find the same belt associated
with other planers. Chances are good your planer is similar to some
other ones with available manuals and schematics.

I know that the Mastercraft brand is sold at Canadian tire www.canadiantire.ca I don’t know if they sell the belt but they do sell the planer.

Thanks much. I have emailed customer service at Canadian Tire, which currently sells a shinier version of the same Mastercraft planer. Wish me luck.

Thanks all for your help. After several tries, got the right-size belt from the good people at beltsforanything.com, and it works fine once again.
