Does a new LHB08100085 motor housing screw into the base of an old SM-303-BTW unit currently installed in my system or are the bases different?

My old unit dated back to 1997 and the new pump easily screwed into the new base--but be sure to use the new gasket (o-ring) that comes with the new pump unit to be sure you have no leaks in the future.

It's threaded exactly the same. The housing is shorter, however, by about an inch (from memory. Rough guess.)

Not sure if this will adequately answer your question, but I pulled my old one out and put this one straight in. Didn't use any other parts or pull anything off of the old one. It worked just fine for me.

I don't remember which model my old ones were, but the 9120B used the same wiring as my old ones. The 9120B did not use the same base or mounting bracket as my old ones, but those are easy enough to replace.

Sorry, the replacement has been discontinued... a sub may be possible but modifications may be necessary since I do not have the specs from the old motor, we would need that information to get close.DanCSH

Depends on the housing. I don't think you'll know for sure until you unpack it and match it against the current guts. I had an older model and it didn't match up. Even though the housing was exactly the same size and fit in the old opening, the fan didn't lock into place the same way. The design was improved. That said, the 9093 I had was pretty old. It came with the house we bought in 2008, and it looked like it had been in there for a while.

No they will not interchange. You need # 32774 hydroflame replacement motor.

I have the exact model and it has 2 switches one for each motor. I would not buy this one!

The screw patterns are different on the bases for the PR10 and PR20 (which I learned by attempting to attach a bushing-compatible base for the PR10 to my PR20), not sure why this is since the only difference I've noticed between the two is the speed control, which has nothing to do with the base.I know the fixed bases for the PR20 can be bought separately (which will work with this plate), but you'd have to ask Bosch if that base will fit the PR10 motor housings as I have no idea personally.

The motor, fan, and housing are a unit. Mine had a label on the face of the motor that gave the manufacturer and part number. Used that info. to do a search and found that there were several sellers to choose from.

often these are generic images... the motor will be correct if you have matched you part number to listed cross ref numbers... it is a 4 speed unit which will have appropriate wiring...DanCSH989-723-8985

The one I ordered did not work because of what I would call a proprietary add on ('wing') to the motor that connects the whole motor assembly. I purchased a complete assembly - eg. http://www.centralvacuumstores.com/nutone/nutone-fan-motor/600-Series.php -- example only, I don't recall if this is where I got the assembly. My opinion is purchase the complete motor assembly, not the motor only as the 'wing' as I recall is attached to the motor by Nu Tone and is not an original part of the motor, and nothing you can likely adapt to the old one.

I early can't remember the model number of the old unit, but this new one did just twist on over the old screws. Hope this helps.

Uf you are changing model for model it will. However, I would recommend changing the set together, just as a preventative maintenance kind of touch. You don't want to take the chance that there is any corrosion in the contacts that could cause another issue with the new module. Also it should only be 2 screws holding the baseplate to the wall and 3 wires, which you swap from point to point. I guess it also depends on how handy you are whether you want to tackle it or not. Remember to shut the power off before you change the base plate though, again just as a precaution. Don't want to short out that new module. Good luck. Uf you are changing model for model it will.

Depends on what your old model was. You can call up the manufacturer of the old module and they can answer your question

i threw out my old motor but that sounds like the same number. It was an exact replacement except that the shaft only had one flat side and mine had 2 but that dont matter this was the best price i found

No. I bought it to replace a 671H, but cannot use it. The threaded screws extend out in the direction opposite the shaft, meaning you cannot mount it to the housing plate with the shaft pointed in the correct direction. I tried flipping the rotor, but was not able, because the bearing block on the side opposite the shaft does not have an opening for the shaft to pass through (btw, the old motor has the through-hole on both bearing blocks). I am returning this fan.

All I can answer for is I took old one off complete and put New one in its place complete. Contained motor, fan and fan housing. Hope that helped.
