Adler 5-37 Only Bottom Feed? (Ser.nr. 30265)

But it is the same type of hand wheel on both your class 4 and 5? The 5 wheel has been modified in all the grooves. If this is the case, I only have to look for someone with a big lathe that will do the job.

Thanks

The groove is 10mm wide. The depth is 7mm. The wheel still looks strong enough. I only now realize that the grooves on that Adler 4 ftatbed are for round belts and all the grooves on the Adler 5 are all for v-belts.

All of my upholstery machines have those very big pulley's. I buy them at ATD. They are fixed with the taperlock system. Works very easy. No need for drilling or whatever. costs about 50 euro's. Without the matching v-belt.

I only bought that Frobana because I like that machines mechanism and it was pretty cheap wil new thread. I payed 50 euro's. The thread alone is 22 euro's overhere without shipping costs. You could use those machines for dress belts and pouches and stuff. Just as a lot of people use the the junkers and pederson's for. Only these needles are cheaper and easier to come by overhere.

An Adler 20 with 40mm lift sounds great. Don't realy need it but I would sure like to play with one sometime!

Maybe the band hired Toledo Bob to replace the rusty zipper!!

Yes it is exaclty the same handwheel. You Could easily modify your's I guess.

I use these pulley's. You can buy those in any size.

The little round thing in the middle (taperlock system) is matched to fit the axis and the pulley. If I would want to fix the pulley on a different machine I only have to buy a matching taperlock. It's a loose component of the pulley.

Hi Sandy!

This is great, exactly what I am looking for! What`s the diameter on those wheels? If I call the company do you think they would ship me one of those wheels for my class 5?

Thanks

Next week I go there myself. Need some stuff for my pfaff 335. I will ask for you. I need the type of v-belt you are using. What are the exact sizes, width and depth/height. Is your axis 15mm? What size of pulley are you looking for?

Thanks a lot Sandy, I could not take the wheel of; I need a take-off tool. I will do that later. However, I was able to take a measurement on the tip of the shaft; 14, 7 mm diameter. But it is maybe 15 mm, it was difficult to measure. The original wheel depth is 62 mm; the shaft length is 63 mm. An ideal wheel would be; 250 mm width and have depth of 37 mm from the center of the groove. A total depth of 62 mm (but that is not necessary, it do not have to cover all of the shaft length. Only have the belt groove on the right place). If it is possible, the belt groove should be the same size as the reducer one or approx the same. It is 9, 5 mm on the top of the V and 4 in the bottom, 10 mm deep. But those pulleys come with standard belt sizes, and my reducer is a “Chinese standard” I do not want you to have any trouble for me, but if you just, can ask for a price. And if they ship it to Norway, I will be very grateful. If I have the approx price, I will compare it to the price of modifying the original one. In advance Thanks

Hi Trox,

The pulley's for the type of v-belt we are using only come in max. 20cm. But the taperlock for that size starts at 18mm. So that's not good.

A pulley for our v-belt with a fitting taperlock is max 18 cm. That's pretty big for a upholstery machine like I used them for but not realy big for an Adler harness machine. The taperlock for this pulley is 14 or 16 mm!! You would have to make your axis bigger with copper foil. Just wrap it around your axis. I did this on all my machines. The taperlock squeezes around the axis, it works great for me. Never slipped or what so ever.

I paid 63 euro's for this exact set including v-belt for my Pfaff 335 yesterday. They do ship to Norway. But that costs about 35 euro's though.

There is an other option. They sell bigger pulleys. Let's say 25 cm like you requested without a hole for the axis. The guy in the shop would get back to me about the price.

They can make a hole for you exactly fitting your axis. That's about 20 euro's.

So it's not as straight to bussiness as I hoped it would be for you.

Another thing. You told me (us) about your v-belt twisting on your pulley. I don't have this problem anymore. I am using a slightly different v-belt as you are using. Mine is 10mm wide and 6 mm deep. Yours is 9,5 mm wide and10 mm deep. Could that make the difference? Maybe your v-belt is hitting the bottom of the groove?

You also have to remind this when you decide modifying your original wheel. My grooves are 7 mm deep. You have to go deeper with your current type of v-belt!!

I never realized before there where that much differences in v-belts.

I guess the smartest thing to do is looking for a different type of v-belt like mine. This will also fit your reducer I guess? 0,5 mm is not that much. Maybe than you can use your wheel as it is?

Hi Sandy, Thank a lot, I better try to get it modified here. I do not want to ask you for more help now.

To modify it like your cl. 5 is the easiest and best thing to do. You have already helped me a great deal, to make the right decision. You are right about the size of the wheel, is not big enough for a harness machine. And when the company does not ship, I better get it done here. I will try to ask in the local school for machinist, they will maybe do it cheaper for a training purpose.

About the belt I am using; my cl. 5 has a very small two-sided V groove (with no flat bottom, see pic.) for a round belt. It is 7 mm at its widest and 5 mm deep.

I found only one V belt that fit that groove, and the core measures 7 x 5 mm. That is the smallest belt I could find with the right length. This belt hits the bottom in the speed reducer groove (9,5 mm width). It is climbing on the hand wheel groove and hits the bottom in the other groove. The two grooves is too different, I have to alter one of them. I will alter the hand wheel one, no square V belt will ever work on this groove.

You have a Pfaff 335, is it with a binder? I had a couple good offers a 335 machine before but I did not buy any. I was looking for a 345 machine that is a bit heavier rated. Maybe Pfaff do not produce the 345 anymore. The new 335 maybe comes with different types and sizes hook. I regret not buying one of the 335`s, despite the small hook, I think it is a great sewing machine. I newer seen a machine (without the 29K and the Juki 441) that is copied that much, It is maybe the most copied arm machine ever. It must be good. You can use size Nm 20 thread in it?, but not 15? With a bigger pulley and a stop motor, it must be good.

Thanks for the help Sandy, I will post the modification of my hand wheel here later.
