Paul H Posted March 14, 2017 Report Share Posted March 14, 2017 The smiths heater motor sounds like its on its last legs - I think I read somewhere the Nissan Micra blower motor fitted though the connectors needed to be reversed to make it blow http://1320.photobucket.com/user/bivvyman/media/heater-motor_zpstcnlrplq.mp4.html Any input welcomed Best regards Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 14, 2017 Report Share Posted March 14, 2017 Some grease on the bearings may improve it some have used VW fans but I guess many eurobox motor can be adapted pete Link to comment Share on other sites More sharing options...
Darren Groves Posted March 14, 2017 Report Share Posted March 14, 2017 The Micra fans spin the correct way, it's the VW fan that some have used which spins the wrong way but there's no point reversing it as the fins are angled for one direction only. Both fans need modification of the heater box. I have used a VW fan in the past and now use a Micra one, you can read about it here: http://triumphherald1360.blogspot.co.uk/2016/01/heater-fanblower.html Darren 2 Link to comment Share on other sites More sharing options...
Guest Posted March 14, 2017 Report Share Posted March 14, 2017 Darren. That's a very good write-up and seems straight forward. Definitely worth considering. Many thanks for sharing it. Regards. Richard. Link to comment Share on other sites More sharing options...
Colin Lindsay Posted March 15, 2017 Report Share Posted March 15, 2017 Am I correct that the motor you require comes from 1993 - 2003 models? The later model (plus the even later one from 2013 on) is a circular body rather than the triangular version in the photos - I must get hold of one and see how it compares. As classiclife says definitely worth considering given the age and condition of some of the originals. I must do some research.... thanks Darren.

Paul H Posted March 15, 2017 Author Report Share Posted March 15, 2017 Following on from Darren's link pretty sure this is the same one , its the K11 heater not £7.50 any more though worth the monies if the correct one Regards Paul Link to comment Share on other sites More sharing options...
Darren Groves Posted March 15, 2017 Report Share Posted March 15, 2017 Not exactly as there are a few minor differences, but looks close enough to be worth a punt. Mine was from a '94 Micra so fits within the date range of the one you've linked to. Cheers Darren Link to comment Share on other sites More sharing options...
Guest Posted March 15, 2017 Report Share Posted March 15, 2017 Paul. This may be better and with an offer + free p&p it has to be worth a £10 - £12 shot !! http://www.ebay.co.uk/itm/331950109763?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Regards.

Richard. Hi Richard - thanks for the link - purchased it for £10.00 !!! I will advise on the fitting progress Paul 1 Link to comment Share on other sites More sharing options...
Paul H Posted March 18, 2017 Author Report Share Posted March 18, 2017 The £10 delivered Nisan Micra blower motor has arrived and the pic shows them side by side , My thoughts are that the Micra blower will fit but it will be a very tight squeeze - its obvious from the pic the increased surface area of the fan so the output will be significantly improved and the air might even hit the windscreen . It wont be a case of simply opening the aperture equally to fit the Micra blower as there isnt enough room on the left hand side inner skin, so much more fettling on the right hand side to take the new heater motor . As usual this is a bigger job than I thought so will be checking both motors are working and going in the right direction , lubricating the Smiths as Pete suggested and putting this one back with the Micra going in later in the year Regards Paul 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 18, 2017 Report Share Posted March 18, 2017 the micra stand off is Quite shallower i can see some metal work involved ....project for when ???? Pete Link to comment Share on other sites More sharing options...
Paul H Posted March 18, 2017 Author Report Share Posted March 18, 2017 Just checked both motors and wow !! the output of the Micra is at least twice the Smiths - a word of warning make the sure both motors are secured using a vice when testing - just got the tea shirt testing the micra blower !! Newbie question , how to I check the amps drawn when the Micra is operating ? and could this be an issue for the existing wiring . I have a test meter of sorts Paul 1 Link to comment Share on other sites More sharing options...
Guest Posted March 18, 2017 Report Share Posted March 18, 2017 Paul. If the Micra has a label on it it may show the watts. If so, watts divided by volts will give you the amp requirement. Regards. Richard. Link to comment Share on other sites More sharing options...

NevSpit Posted March 21, 2017 Report Share Posted March 21, 2017 Now that looks like it could make a substantial improvement in clearing the screen on those steamy days... Does anyone know if the same motor can be used in a Spitfire MKIV - the part numbers seem to differ but not sure what the physical differences are. I recognise the Spit is a two speed fan and we are looking at a single here but one decent speed is good enough. Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 22, 2017 Report Share Posted March 22, 2017 apart from all smiths motors of this generation have the same basic casing i have no idea. Pete Link to comment Share on other sites More sharing options...
Guest Posted March 22, 2017 Report Share Posted March 22, 2017 Hello. There is, what appears to be a decent casing up for auction on Ebay http://www.ebay.co.uk/itm/TRIUMPH-HERALD-VITESSE-HEATER-BOX-/222445735026?hash=item33cacc8c72:g:b2sAAOSwnNBXUHi9 Perhaps worth a purchase if considering such a conversion, without stripping your own unit out first, whilst constructing for bench test purposes. Just a thought. Richard. Link to comment Share on other sites More sharing options...
Casper Posted March 22, 2017 Report Share Posted March 22, 2017 There is, what appears to be a decent casing up for auction on Ebay http://www.ebay.co.u...2sAAOSwnNBXUHi9 That's a Delaney Galley casing. Never fitted to Vitesse (I guess because the valve gets in the way of the larger engine. C. 1 Link to comment Share on other sites More sharing options...
