Hayter Harrier 48 BBC part

[feldhaus]

Hi,

 

My 1998 Hayter Harrier 48 BBC autodrive (CODE485R) seems to have a slipped and/or broken friction disc on its Blade Brake Clutch.

 

A very helpful thread here indicates that the lower half of the BBC can be replaced with John Deere p/n SA35980.

 

Would I be right in thinking that this is the same as their GY20711? A few European sites seem to list the part with both numbers but the UK vendor I'm planning on using only refers to it as GY20711.

 

Thanks for any help.

Just a follow-up for anyone finding this thread:

 

SA35980 does seem to be compatible with the 1998 Hayter Harrier 48 BBC. I installed it today and all is well.

 

As noted elsewhere, removing the retaining bolt can be rather a pain. I used a few carefully placed drops of Plusgas, an appropriately sized Allen key and a hammer to whack the latter to get the bolt moving without turning the entire drive shaft.

 

Plan B was to (buy and) use a piston stop tool (or length of recoil rope) to stop the engine turning with the bolt.

 

Plan C was to buy an impact driver which would clearly have done the job pretty much instantly. I've heard great things about impact drivers so will probably invest in one for next time.
