Diesel Heater Motor Replacement - I finally destroyed it !

[@easymac79]

I saw this on my homepage - not expecting another video so soon, and not specifically needing info on how to replace the motor, I skipped over it. Another update, fantastic!

[@loweredexpectations4927]

Haha.... yeah... I normally do Sunday and Wednesday... but I'm trying to get caught up... this video isn't an experiment so I wanted to get it out quickly so I decided to release my experiment video Saturday and quickly edited this motor video for today. I highly suspect that most of my regular viewers won't be interested in this, but many people replacing a motor will be.

[@PeterWinnett]

Just a small thing. When re-installing the centre of the motor shaft I have always found it better to tie back the brushes with thin thread or cotton. This reduces the possibility of damage to the brushes. Once the shaft is in place just pull the cotton out :) Great channel btw :)

[@loweredexpectations4927]

Thanks for the comment. I have worked on starter motors and winch motors mostly, and I have used this technique with zip ties ... Your idea would work well on these small motors 👍 Cheers !

[@HB-et5iv]

Great idea! Thank you for sharing it.

[@jorgruthschilling]

Definitely a great tutorial on how to replace the blower motor and also on how to replace the motor bearings. The motor bearings are often the first part that has to be replaced after a few thousands hours of operation. BTW, some Chinese diesel heater blower units have balanced fan wheels. They make small little cutouts in the factory to balance them. These balanced units run less noisily and the bearings last longer.

[@loweredexpectations4927]

I recorded a long rant about the armature being balanced and decided to not include it because it went on for way too long ... haha. Any decent motor will be balanced ... It would be nice if they also all balanced the fan(s) ... but sadly they don't.

[@HB-et5iv]

[@loweredexpectations4927]

@@HB-et5iv Yeah... a person could do some fine tuning in this for sure. I'd be happy if I could get mine to run for more than a few days on waste oil ...

[@MrMinnesota99]

You can pull the brush springs back so they rest on the top of the slot, making it easier to insert the commutator. Then release the springs back into the slot.

[@loweredexpectations4927]

yes, that is one way to go about it 👍

[@easymac79]

3:50 They are INCREDIBLY easy to disassemble. I noticed 3 rubber isolation pads on the forward (outlet) side of the heat exchanger. Presumably there should have been 4? Quality control error I guess. 9:05 I'd call it a "spacer ring", or possibly "stabilizer bar" because of the extensions. It's a "spacer-stabilizer bar-ring"; LOL. 14:35 YES! Super awesome that you point this out. The first time I had my unit apart that lip was driving me crazy. I was just trying to mash it together then I decided to use more than 2 brain cells and engage my eyeballs.

[@loweredexpectations4927]

Yes... it's almost like they put some thought into these needing to be serviced from time to time... that's an odd thing these days. I have only ever noticed two isolation pads but assume that there should be one on each corner, yes. Yeah... I'm sure they call it something like the "motocentric, case locating, stabilization, yoke assembly" LOL ... yes, I've seen videos of others struggling, so I decided to mention it.

[@yuri210fun2]

Usually there is a little slot or hole in the front of the brush holder...normally you can push the brushes all the way in to holder and put a paperclip or something in the hole or slot and lock them all the way back...now you can install the rotating part in the housing and than instal the backplate with the brushes and not risk the wires getting crushed because of the magnetic field...just before it is completely set you just pull out the paperclips and the brushes are set into place....hopefully this makes your life a little easier in the future when working on electric motors 😁

[@loweredexpectations4927]

Interesting. I have never noticed that before. Most of the motors that I work on are starter motors. That would make things easier. WIth bigger motors I use zip ties to hold the brushes and start the assembly with the rotor in the magnets and slide the end cap on after. Good stuff 👍

[@cheepshotz]

We think alike sometimes. Keep up your good work.

[@loweredexpectations4927]

I love channels without background music. Can always add my preferred noise myself, if needed. My 2cents referring to this topic. Man, what an incredible job, explaining just everything the same time you manage to go straightforward without any time wasting bs at all. That's either a lot of practice or you're a natural. You may as well try to make a career as an actor with your attitude and talent. Mechanic are underpaid anyhow. I'm really impressed. Makes me think to practice a bit for better videos.

[@loweredexpectations4927]

Thanks for that comment. I feel the same way. I sometimes add music and on my other channel I do it in almost every video... I don't understand it, but the majority of people want some soundtrack and leave positive comments about my editing when I do.... but I dislike it, haha. That's very kind of you to say... I don't know that it's a natural talent or practice, perhaps a bit of both and being somewhat confident about what I'm talking about... and the magic of editing, haha. Most of the little add in clips at the first of the video, end and me talking directly to the camera... they take several takes to get the words out.

[@peterlumper5376]

I find the easiest way to get the black fan off is by pressing a coin on the centre spindle with both of your thumbs whilst pulling on the edges of the fan with your fingers. It just pops off with ease.

[@loweredexpectations4927]

I'm not really sure what you mean. The shaft is flush with the fan. wouldn't the coin just push on the fan ?

[@PUBHEAD1]

Awesome stuff my friend, it's very interesting to see how this all goes together. Cheers

[@loweredexpectations4927]

Thanks PUB !

[@NY411Info]

lol, the first thing I did when I got my Diesel heater, was to take the housing apart. I knew that the machine probably was not assembled very well. The pump was loose. the wires were not well routed. The wires had no grommets through the sheet metal. The screw in tank nipple was loose. So yeah. Definitely was not assembled to my specifications. Credit to opening my unit and checking goes to David McLuckie. Shout out.

[@oliver90owner]

The ‘damper’, as you call it, in the one motor end-cap is to allow axial expansion as the motor temperature changes, without affecting the commutator to brush position. There is always one bearing in an electric motor that can move axially, for this reason. Sometimes the bearing can move within the sleeve and sometimes the outer bearing support can be movable.

[@loweredexpectations4927]

That's an interesting take on it... I'm curious if you are guessing at this or if you know from engineering. I have never seen a commutator that is so short that the thermal expansion of the motor would affect the brushes at all... this would be a few thousandths of an inch. It makes sense that the motor should be able to move axially so that nothing binds. I don't know a lot about electric motors. From what I have seen, motors typically have some sort of thrust washers on each end of the rotor so that the movement is limited in this way.

[@patchvonbraun]

Those small PMDC motors aren't generally worth servicing, except as an item of curiosity. But, cool that you took it apart and showed us what was wrong with it. I'm currently playing with a 2kW BLDC motor. They don't have brushes, but they need a controller to work.

[@loweredexpectations4927]

I agree... it doesn't make sense to service them... I just like taking things apart ! haha.

[@HB-et5iv]

For people trying to replicate, it might be worth mentioning the gasket your heater probably "lost" somewhere along its journey but which some people may want to replace if it breaks during disassembly :)

[@loweredexpectations4927]

Yeah... I should have mentioned the gasket... I haven't used mine for so long it slipped my mind.

[@HB-et5iv]

Personally, I'd be more comfortable with that gasket in place. Scared of CO "blowby" into the room...

[@loweredexpectations4927]

@@HB-et5iv Yes, I would suggest using all of the gaskets. This heater is a test bed for all sorts of experiments and I literally take it apart 4-5 times a day, so I don't always use gaskets. I'm also not sleeping in my garage, so I'm not too concerned about CO. I'm also not convinced that any CO can / will escape, because the system is under positive pressure from the combustion fan... The gasket is pointless as there is a large opening where the air goes into the burn chamber. The pressure on that area is equal to the area at the gasket surface, but there is less resistance. That being said would still recommend doing it the way the manufacturer intended.

[@thesurvivalist.]

A week after I put the muffler on my heater started shutting off, and there was fluid in my exhaust pipe!

[@loweredexpectations4927]

Fluid as in water or fluid as in fuel ? My exhaust gets too hot to collect water, but last night I did have oil dripping out of my ventilation system, haha.

[@hawkkim1974]

you made it look incredibly simple to take out those two fans. In my case, it was a major pain in the neck to take out the inner blow fan when I had to replace noisy fans from a cheapest ever chinese diesel heater.

[@loweredexpectations4927]

Hmmm. I have had mine off a few times to clean it, so it probably came off easier than most, but it was never difficult to come off. I guess perhaps I just got lucky. I'd like to claim that it was my superior skill level from being a mechanic for 28 years... but this time I think I just got an easy one😂

[@bendavis993]

I have seen that their is a high pressure pipe system that they can connect to your dpf and clean out all the gunk, by running some sort of liquid through it , that could be the solution, drill a hole into the chamber and attached hard pipe , some how run some sort of solvent through it and suck it out through exhaust, every one snd again when turned of

[@bendavis993]

Tbf if the solvent could evaporate, could just pump it into the chamber and see if it delodges anything , pump and suck maybe and the rest would just disappear

[@loweredexpectations4927]

That would be really cool if it works. I really want to try steam / water when it is running but I need to work on getting it nice and hot first.

[@loweredexpectations4927]

🤣 Seems like an odd video for this comment, but no... My neighbours all love me. I'm a very helpful guy and they love me. My garage is very well insulated 2x6 walls with 3/4 plywood on the inner walls, 1/2 outer sheathing and stucco... not much noise gets out. Also, my neighbours across the alley thad a house fire a few years ago.... I found out by the screams of a little girl in the alleyway.... I jumped into action to find out that their grandmother was trapped inside. The family, all crying and screaming could only call 911. I started barking out orders to get buckets and garden hoses, but they were all frozen in panic.... I got a garden hose smashed in the front door and got to see this poor lady dead in her living room chair because 8 - 10 people who knew about the fire decided that it was someone else's job to put out their fire... I stopped their house from burning down and walked away when the fire truck arrived 5 minutes later..... I was so incredibly angry and disgusted. It took me a long time to get over it. I don't understand people like that as much as they don't understand me... When shit goes down I do what needs to be done. If my garage burns down it will be because I was away or asleep. ... and I don't leave the heater running at either of those times.
