	Husqvarna 50 Magnum

	Husqvarna 50 Magnum with Partner 5000 plus piston cylinder
	New thread from the old husky thread to save info. Guy in my FB
	CR group has one.
	I questioned the use of the smaller white top 50 crankcases as
	seen in pic and SB. Putting a partner 5000 topend on one of
	those. See specs.
	I recall my white top 50 had the smaller cylinder base. =
	(Back in the 80's we were selling a Husqvarna 50 Magnum. This
	saw was created in Charlotte, NC by the Husqvarna Distributor
	owned by Jim Thompson, The guy that made Husqvarna as far as
	I'm concerned. They brought in Partner 5000 cylinders and
	pistons and put them on 50 Rancher (the old white top) saws.
	These saws were awesome. The first one I received we got out of
	the box on Thursday and blew the competition out of the water
	on Saturday at the Races. Back then we had Chainsaw
	competition's on monthly bases. Husqvarna Sweden made them stop
	building them in the states. We built some ourselves after they
	stopped. It was a simple bolt on with no modifying at all.
	Someday I'll tell you more about the old Husqvarna distributors
	that made Huqvarna what they are today.)
	I ask owner if they were marked in anyway. = Yes, it was Husky
	Power out of Charlotte, NC doing it. A letter "M" was added to
	the serial number plate to the modified saws. I'll see if I can
	find mine....
	Will share pic here of it when he post the saw.
	Info from SB.
	To go with what Corey was saying. Here is from the SB link
	posted here under files. = The differences between the model 50
	S and 50 R are among other things that the displacement
	is increased from 49 cm3 to 51 cm3 and that the SA-silencer is
	replaced.
	Due to the changes above, the 50 Special has gone through a for
	each country new specific
	testing procedure. This means that no 51 cm3 cylinders should be
	mounted on saws with
	lower serial number than 9190006.
	The 51 cm3 cylinder base does not fit the crankcases of older 50
	R models.
	�
	�
	�
	�
	The 51 cm3 cylinder base has the outer diameter of approx. 49,7
	mm (the outer diameter
	of the piston = 45 mm).
	The 49 cm3 cylinder base has the outer diameter of approx. 47,9
	mm (the outer diameter
	of the piston = 44 mm)
	The inner diameter of the new crankcase is approx. 50,5 mm (this
	crankcase is identified
	with the improvement code F)
	The inner diameter on the old crankcase is approx. 48,5 mm
	CC added = It was in the 1986 model when they went to the grey
	tops the cylinder changed but they used the same piston, then in
	89� the 50 specials used the 45mm 51 topends.There also was some
	late 1988�s i think that got the 45mm topends and labeled as
	300th anny saws , last 8 weeks of 88� production run if i
	remember right.

	Long time dealer in FB group CR , Jerr said that serial number
	break should be = that cyl/case change was somewhere between 81
	and 85

	Only marking that is on the husky 50 magnum.
	He said his dad bought new and was a white top.
