Topic tags/keywords: question jointer refurbishing jointer

I am trying to find a suitable drive belt for subject jointer. It’s part number is 49-138. All web sites I’ve checked show no replacement is available.

I’m hopeful that someone out there has a very similar Rockwell or Delta jointer (same brand / same 4”), the belt for which is a useful / workable substitute. The belt on my jointer is 13 3/8” (+/- 1/16”) in diameter (long?) by 7/16” wide. It has inside parallel ridges.

Also will need new knives….think I found some that would be suitable but if you have a source / part no. that fit, would also appreciate knowing what you’re using.

Thanks, Chris

A place to find belts is a auto parts store. The pep boys near me let’s me browse the belt isle until I find what I’m looking for.
Be sure to put the exact same knives in that Delta recommends. You’ll find them if you search long enough.

Good Luck

Hey Aj,
Many thanks for your reply and suggestions. Hmmm… we have Pep Boys in Sacramento- none close..but I’ll bet that some of the auto parts stores around here may be willing to let me look through their belt stock.. May have to wait until the quarantines are lifted. Sheriff promises to get tough on stores (other than grocery) that are open when they’ve been told to close and stay closed until…..
Will look for the knives online. If anyone else reading this has purchased knives for the 4” 37-000 (or equivalent), please let me know.
Thanks, Chris

What is the model number of your jointer (37-000 is not a valid #). I could not find a cross reference for the belt number you gave, but Renovo appears to have them in stock. And like AJ said, you can get them from any place that sells belts… there is nothing magical about them. 13” is extremely small… are you sure that is the correct OD length? Is there any markings on your existing belt that can give a clue? The popular 4” 37-290 jointer takes a 44” belt (p/n 49-034).

Knives are the same deal – you can find them all over as there should not be anything special about them. But you need to know the proper size, so a model number will help with that as well.

Cheers,
Brad

My favorite source for unknown belts in Napa Auto stores!

Find a Napa Automotive branch (like the one on Placerville Drive). Give the counter clerk the belt, and 95% of time you walk out with right belt. Occasionally, they send to me another store due lack of inventory, or ask me to return next day after they order one. They have a tool for measuring belts and can also tell you what size (width/length) you need.

Have had mixed luck making the same request to other auto stores like; AutoZone or O’Reilly stores.
Some are great, many stink.

Other local sources for drive belts:
Tractor Supply
Farm and Fleet Stores
True Value/Ace Hardware (stock mostly 3L/4L belts for lawn mowers)
Ferguson (they have many types of branches)
The Ferguson on 2850 Cold Springs Rd in Placerville does both plumbing and HVAC. There are a lot of drive belts used on commercial HVAC and Swamp cooler systems.
Electric motor sales/repair shops (like H&M in Sacramento)
Motion industries (Ramona Dr Sacramento)

Last but not least, Here is random online reference to help you understand common sizes of drive belts:
https://www.vbelts4less.com/how-to-measure-v-belts

Belts are easy to find. The challenge is can you find the right size?
Once you find an expert to determine the right size, WWW always has source some where! :-)

Best Luck.

Gates have charts to give you their part#. How you get the Gates part #. It will be the top width of the belt, then the inside diameter of the belt (the inside diameter will be 2 inches less then the outside diameter). I have part # charts for the Gates belts. But I won’t be back to my shop till Saturday. This is normally the universal standard for belt parts #’s for all the belt manufactures.

Hi Mr. Unix, Captain Klutz, WoodenDreams, and Aj,
Thanks to all for your helpful posts:

Here is the Operating Instructions catalog for my “Jointer” .

I found this manual after my very first post was posted (which was in the “review” process and not put on this forum for a few days.) The manual is in PDF format and can be downloaded. (thanks to Vintage Machinery.org)

http://www.vintagemachinery.org/pubs/detail.aspx?id=21586

The belt is part # 49-138 ; (it’s in the parts list)

Even though the marking is not so good on my belt, here it is: 14 IN ROCKWELL CAT. NO. 49 138; Bingo!

All that said, I was not able to find any belt with that PN anywhere. I have a hunch, however, that the 4” Jointer models following this one might use the same belt under a different PN… wishful thinking, so far.

We do have a NAPA store real close – staff is very friendly. (Captain Klutz…are you a neighbor of mine?) If they’re not closed, I’ll go looking there for a suitable belt (all non-essential businesses have been ordered by our governor to close until the all clear is given).

I believe the pics in the above referenced manual will help

Really thank you all…. will look for any further comments or advice.

Stay safe!!!

-- Chris

No, LOL. Although I have driven through area a dozen or more times?

Try typing this into google maps:
‘Drive belt near Placerville, CA’ or
‘motor repair near Placerville,CA’

Anything is easy to find when you know HOW to search.
wink, wink..

IMHO – OEM belt part numbers are almost useless. A drive belt is drive belt. Don’t be scared to use automotive fan belt or snowmobile belt on your jointer.

Cheers!

Son of a salamander… never seen one of those and they are not in any of the Delta/Rockwell catalogs that I can find! Anyway, I don’t believe that is a standard V-belt… it’s more of a small serpentine type from the looks of it. It is a small little thing, and I doubt you will find it at any auto parts store – but Renovo says they still have them and they are only about $8.

So everyone knows what the machine looks like, including a good shot of the underside showing the motor and belt, here is a good photo entry of one over at the vintage machinery site: 37-000 Compactool

And here is a shot of the belt from Renovo:

At least that explains why I couldn’t cross reference it – my list is only for Delta/Rockwell V-belts and pulleys :(

For your knives – manual states it takes the #37-026 set, which is pretty common across most of their 4” jointers. Those are 4-1/8” long by 5/8” wide, 3/32” thick – but they don’t have to be exact. A 4”x5/8” knife will work just fine, such as the Freud C310 set.

Cheers,
Brad

Also ordered some knives.
Will get back with a full report. Won’t be until after the 9th … not quite Amazon shipping time but close.

Hey Brad…or anyone that knows an answer to the following dilemma />I ended up ordering the knives from a seller on eBay, Oella Saw and Tool; the knives are the same size as the Freud C310 set. They came today. However, the seller wrote this note on the bottom of his invoice: “Before you open the package, measure your knives. Are they 1/8” or 3/32”?”
So tonight, I removed my stock knives.. found out that the screws holding the knives had to be slightly adjusted for each 1/8” (or so) of knife movement as I levered the knives out of their slot. I found out why the slight screw adjustment was needed. The head of each screw is “oversize” and fits into a slot (two slots) in the knife itself. The knives I got from Oella, and the Freud C310 set, do not have these slots…so not sure (yet) if the new knives (no slots) can or will be held down by the original screws… maybe the fact that because all the replacement 4” knives for these Rockwell/Delta jointers are 1/8” thick and the original “hold down” screw heads work because there’s 1/32” of extra room to allow the oversize screw heads….?? Or ??? Am I screwed or not?

Wow, I just took a look at the manual and you are correct – the knives for that jointer do have little slots in them for the screw head to hold them in place! Weird design, and doesn’t really look all that safe, but I guess it works. Unfortunately, I don’t believe you will be able to use the new knives as-is because of that. However… the original knives you have can be sharpened, and since they are the correct ones for your jointer, you have a reference as to where the slots need to be. Find a local sharpening shop around you, they usually can also do modifications, and could put those slots in for you. Get the original knives sharpened, and have them modify the new ones so you have a backup set.

Cheers,
Brad

PS: I really feel bad that I steered you wrong on those knives – I should have researched it a little better.
