Hi, new here... just recently we purchased used Murray lawnmower which had Husqvarna badges on the side panels :S (originaly bought in Germany I think)

model No# is 31621x66B
date of manufacture: 3143 (so it should be 1993 right?)

long story short, mandrel housing (055962) was a toast, so it needs replacement... mandrel (091922MA) looks like it's altered something else and pulley (091951) rotten out...

So I wanted to order new parts, but have trouble finding manual for it...

on Murray web page I found closest manual for 31621x70G which lawnmower looks same on pictures as ours but it's 1996 and our mower should be 1993 by DoM... but I guessed because it's the identical on the pictures it should be it...

So i ordered parts by catalog No# in that manual... now it came by mail... housing is probably the same (not much left of the old one), but new ordered bearings are smaller in inner diameter, mandrel is thinner and 30mm shorter owerall... but I don't know are those I got with mower original 1993 or it broke down and someone made and fitted alternative...

So, how to be 100% shore that bought parts for 1996 year fit in 1993? Because if they don't fit I need to send them back for refund...

Thank you for understanding and quick answers

Not sure about the Marrays sold outside of the US.
Take some pics and put up here, as well as measurements of your old stuff, and go to an aftermarket catalog like this one to find the parts you need.

Considering that the mower is so old you might be better asking your question on the Murray Owners World group.
This is a good group of Murray fanatics
Murray made mowers for Husqvarna before Husqvarna bought AYP where their mowers are now made.
Murray also made mowers for Stihl & John Deere.

Last time I was there , they had parts books back to the 80's

on these pics you can see old mandrel looks nothing like new one but there is difference in length so I'm guessing that is something improvised by first owner... I don't have pics of full assembled mower, but it looks identical to one in the schematic picture... Parts I have with me now are new mandrel and mandrel housing with bearings... all other including mower are 120km away at my parents house.

New mandrel is 161mm long and 15,8mm thick where it goes in bearings... mandrel housing is 70mm tall...

Thank you for help, will look in to it

Measure the length of the shaft, and take the rest of the remains off of it, it likely looks very similar to this.
But there were several different lengths of this style shaft.

Here is what it likely looked like before all of the damage, we just need the length. You will need that spacer too.

Any remains of the old pulley?

it was 190mm in total I guess +/-... endcap can't be pulled, looks like it was welded, spacer might be pulled if soaked in diesel or some release agent... but I don't believe it was that one... because this one has more coarser threading, splinter is actually material welded on it then filed, IDK about threading in the middle?!?!?!

pulley was cut in half because rotten at connection with shaft, it was 190,5 x 14.3mm (9/16" x 7 1/2")... I don't have it near to take pics :s

I would say that the coarse spiral was from rotational metal/metal contact. The top piece is just the center of the pulley, It is a snug fit + a woodruff key. If you have the outer part of the pulley, we will need to measure the 0.d. of that as well.

Here is the pulley.

Top pulleys regularly have to be removed with a press which requires removing the entire housing .
Usually the housing breaks when you undo the mounting bolts so you are up for a whole new unit.
Shaft comes out to the blade end so if you can't get the pulley off you cant get the shaft out.

circled red endcap (pulley center) is just snug fit? should be heated a little and light tap to release?
circled greenis spaces that is also rusted snug fit i guess :S
circled blue is coarse threading I had in mind... that can't be from metal to metal contact, it hast to be machined so I'm guessing they lathe fitted some rod to spindle, even made lug nut thread different than original...
circled pink is woodroff key that is actually made by welding material to the shaft, it's not removable and it's not notched in spindle, so I don't know what to expect under that end cap remains of pulley center...
by the looking of blade it has "5 leaf clover" hole like Husquarna has, so I'm guessing that spindle assembly is some sort of Frankenstein, because lack of Murray parts in this part of EU :S

you can't remove this one with press because it's blind cap on top of spindle :S that's why we cut already rusted-welded-rusted-welded pulley to try remove it (BTW. I tougth I will have more trouble finding spare housing than pulley... boy I was wrong...), and housing was already broken when we got her, but my father finished it off with using mower with almost no brakes and went over the large stone, so housing was needed either way...

this shaft came out on pulley side, but if that endcap remains of pulley was removable, I think it can go either way... it's 17mm straight with no wider parts like original bought...

so, verdict... we are dressing up old spindle (returning new bought) and keeping bearing housing but changing bearings to the right inner hole dimension... and then have to find some pulley that is same outer diameter and fit it with lathe on old spindle :S looks a lot of work but wit access to machining and welding tools might be cheaper than ordering again because this wrong purchase costed me $70 already... :S and whole lawnmower was $230... If I go for new spindle, I need to buy all new whole vertical assembly from bottom bolt nut to the top bolt nut, with all accessories :O and that might total with shipping more that whole lawnmower was paid...
