You're lucky you have keyways, I'm building a 406j roots blower, and there's no timing alignmentarks etc, i made my own before dissassembly luckily on the shafts* Ibised a carpenders square to check alignment on the marks i made* The seals do go with the open end facing out, that deals with 2 issues-1 installation on the shaft is less likely to rip the seal* 2- the oil will stay in the case better woth the seals design.
Thanks for the explanatory video, I followed the entire procedure with the clearances and it releases air through the witnesses where the Teflon is, therefore it does not raise the appropriate pressure, could you help me with that?
Heat the inner race only and work fast tapping each position n,s,e,w of the inner race till bottomed out let cool to room temp then make sure it is seated again it could draw off the shoulder a 1/32
Buen comentario, es un tuthill y se puede observar el error en los sellos porque empieza a expulsar la grasa por donde no debería al momento de lubricar.
Never used one of these vacuum/blowers. How often do they need rebuilt? So far just been using the shop vac type with pump out as we don’t have to reclaim that often but planning to build my own with this type
Hey D, rebuild frequency depends heavily on three things: how much water or moisture is making it through the blower either in vapor or liquid form, how much fine grit small solids and debris make it to the lobes chamber, and how much non neutral PH (detergents and cleaners). All this causes them to rust out and lose internal clearance and eventually bind up and jam up to the point where they won't rotate at all. I've seen them go to hell after less than 6 months, and I have some that have gone upwards of 3 years and still spun freely even after that much time. Do not let your capture drum fill up and let the blower start sucking water and debris when the pumps get backed up, and don't put them up wet after a work day. run the blowers for a couple minutes sucking clean dry air to dry off the lobes then fire some WD-40 into the intake right before shut down to coat the internals in light oil prevents rusting and gumming up.
High vacuum grease on the seals and as far as the sand you killed that blower should always blow out brake clean body and plates brake clean again and feel with your hand or put wd40 on a rag and wipe all the places you can reach and the ones u can’t make something the particles will stick to that rag showing the cleanliness of the parts
On a bench in a shop, not in any working application, or moving any type of media. Until you run out of gas or the power shuts off. Our application is probably the worst and has the least run time between cleanings and rebuilds.
@benshrope5707 I installed them the same way, and they folded on me. The spring came out of the seal too. Trying to figure out how to install new seals the other way ( backwards)
@@ShowMeMO-Digs Normally the seals are fitted in the opposite direction to that shown in the video, so it is at least in Edwrads roots pumps, I am fitting one right now. EH500. There are two good reasons: 1 By mounting them upside down, their seal is better 2 When mounting the flanges there is no risk that the seal will break.
Sí tuvo problemas al colocar los sellos al revés, se puede observar que al final del vídeo la grasa no sale por el desfogue ubicado en la parte de abajo del blower 😅 y empieza a salir detrás de donde se está inyectando.
Rule of thumb lip goes towards whatever you want to keep out or keep in gear side lips face towards the gears or spring side keeping oil in there is consequences for reversed seals in anything you build and again heat the gears round 200-212 degrees flipping it while heating so heat evenly disperses
Our blowers made by Tuthill, use “HEC 100 Synthetic lubricant”. That’s an oil the the carpet cleaner machines use, not sure why. I’d refer to your users Ma yak for the correct oil for your blower and type of work. In a crunch, I’d chuck some synthetic gear oil, like 75w, and not worry about it…
@@PolyVshot Thank you for your help. In advance, I want to ask you about a problem with my machine, similar to the one you cleaned in the video. It is making noise, and I did not know what is the solution?
I cringed so hard through this entire video:( I hope no one is taking this as a "how to" video. If I were a customer watching my blower be put together like this, I'd be absolutely irate.
Ya, that’s because this video is for reclamation pressure washers to rebuild a blower themselves, so they can spend $300 instead of $1,500 to a professional industrial repair shop, that they don’t have, because they are getting crushed trying to compete with pressure washers underbidding work by doing it illegally. We do not provide this service to anyone, we do it ourselves FOR OURSELVES, to save money. Put up a link to you own video that’s better, if you have one! One that also shows people how to time one of these things. Which you don’t…
