1997 Husqvarna 232R Brushcutter/Clearing Saw - Bevel gear lube

Got myself this brushcutter from friend who no longer needed it, in good condition, starts and runs beautifully ( so far ).

Asked him about last service and he said never- doh.

I put about 10 mls. of grease into the bevel gear housing and it promptly spray-painted the side of the shed when I started it up.

Downloaded a manual from Husky website and the only info on the bevel housing is to 3/4 fill it with Husky special grease which I will get, but wondering if there's a seal needing replacing, or was the 10 mls. too much and it flung out the excess. From what I can see peering into the fill hole it looked quite dry after a short run.

I know the local dealer will just say " bring it in " but I'm a DIYer. I've been fiddling around with Ducati motorcycles for 40 years and am quite familiar with setting up bevel gears :-)

There's a little freeplay and can't feel any sign of roughness when turning the gears by hand each way with a bit of resistance.

After my recent experience with the Masport mower I'd like to keep this machine in good fettle.

The bearings are the seal so the bearing seal must have failed lower bearing part number 503252301. Best to disassemble and inspect it

Thank you for that info, and as cheese says "God bless".

Will tear apart the bevel housing next weekend, and report back.

Have the bevel drive housing stripped to the stage where the bearing SHOULD be dropping out but seems the inner bearing race is stuck to the splined output shaft.Got the circlip out and the thin three pronged shim is out. Have use some gentle heat too.

Can get the outer bearing race moving up and down inside the housing about 1 mm

Have several washers sitting on the large splined dished washer so I can hold the shaft from turning and use the 19 mm Left hand nylock nut to exert a decent pull to draw out the shaft and bearing together however seems any further winding on the nut might do some damage.

Maybe next step is to pop out the bearing seal and try to use a very small bearing puller to slide the inner race off the splined shaft but have never seen such a puller.

Any suggestions please. Do I have to remove the input bevel shaft - cannot do that altho there's a little hole which allows me to spin the nylon bit around inside the housing.

Heat the housing with a heat gun.

Thanks AJ - not enough heat was the problem.
