Hi All,

The Rickman Ranger (MKII 1300 MkII Escort based jeep style kitcar)
has been unused for a few months and as typical the engine starts
first time but the Kenlowe fan doesn't.

I think this would have been the second one in there, the first
failing under similar circumstances (unused for a while).

I've spoken to Kenlowe c/s and a very nice man tells me he can still
supply a replacement fan motor but it will be 80 notes delivered ;-(

Soooo, before I splash the cash, has anyone opened one of these
'sealed' motors and can tell me what goes wrong with them and
therefore could I salvage it do you think please (I have more time
than money atm and am a reasonably good 'old school' engineer).

All the best ..

Same as any motor, they seize up the bearings and the armature gets coated
in crud and the brushes stick, so rip it to pieces and have a look, you have
nothing to lose. If it is turning freely then power it up and give a good
whack and a manual spin, it may start up, rather than spend good money, just
go to a scrappie and buy a suitable looking one from something modern,
almost everything has them now, about ten to twenty quid should do it. I
have a big heap of electric fans, just in case, off various things if you
are in Essex.

Ok, well if it's worth a go then I will thanks (I have to drop the rad
out and wasn't going to bother till the new one arrived if it wasn't
worth a go)

> If it is turning freely

It wasn't (seized solid) but with a bit of gentle assistance / working
back and forth it at least goes round and actually 'tries' to run
under it's own steam (I shorted the contacts from the thermal switch).

>rather than spend good money, just

I did consider that but it's all a bit tight in there I'm not really
in the mood / position to do anything major on it at the moment (If I
fit anything thicker than the Kenlowe I'll have to move the rad back
towards the engine and start playing with hoses etc etc).

Well thanks very much for the offer and I may well take you up on it
(I'm in Herts) but I'll do as you suggest and try the strip / clean
out first. (I did that recently on our AEG washing machine motor (it
was tripping the CU) and saved myself �100+! ) ;-)

All the best ..

For �80 you can buy a brand new fan and have change.

What make please Conor, got any links etc?

I've stripped this KLM1708 motor down now and it is absolutely full of
rust (both the rotor and commentator areas). ;-(

I don't know how it could get like this because it is (or should be)
pretty well sealed and the cable entry was facing down as the label
suggests.

Having said that I had marked it and it looks like it was either the
one we fitted when we first built the car or I swapped it out in 1991
(so 18 years can't be bad either way I suppose)! ;-)

Sooo, I can either buy something 'else' (for under 80 quid new you
suggest Conor?) and possibly have issues re fitting (there really is
no room in there as it all stands) or buy the same again (just the
motor, the fan is ok) and just wack it back in again, knowing it will
all just 'work'?

All the best ..
