G'Day Gents,

I noticed the other night, that the main clutch lever pivot pin has a lot of slop where it goes through the bell housing. Is this normal? Should I add new pin and bushes to my list of rebuild tasks? :crazy:

Also..... Now this really shows my greenness to Cat's..... :baby:
Is the main clutch activated (allowing engine to turn independent of the drive train) when pushed forward, or pulled backwards? This is of course subjective to you sitting on the seat. 😊
I am sure my operators manual says that it activated by pushing forwards, but that's not what it looked like as I looked in the inspection hatch.


Cheers,

Phill.

Hi Phill, the main clutch is engaged when you pull it back towards the seat, it should be adjusted so it has distinct snap feeling as it engages, the little clutch lever on the pilot motor is engaged by pushing forwards towards the radiator.

A lot of wear in the main clutch lever pivot point is not unusual, if the main clutch engages and works as it should it is up to you whether to re-bush it.

Have you got the head off that diesel motor yet?
Regards
Mike

That shaft is commonly worn out. It's one of the ones I refer to a butter brinnell hardness. Cheap low carbon steel shaft that should be upgraded.

It sounds like an easy replacement, if it's mainly the pin that's warn. I will put a 4140 pin in it. 😊 That'll stop the ware nicely. 😊 I just hope the hole's not badly worn. I hate setting up my little borer. It's a real pain in the backside.

I haven't touched the head yet. I have been a bit preoccupied with my divorce just lately. I have the paperwork to get her witnessed signature on, and then it goes to the courts for stamping. I will take it over shortly.

I did attack the pony motor this afternoon with the high pressure cleaner. It's up on the fitting bench, ready to be pulled apart for overhaul. Once it finishes drying. 😊
There is one part that I know has to be replaced, and that is the little alloy thing at the base. It's either corroded away or broken. Either way, I won't know till I have it out. 😞

I suppose that begs the question as to what is the best product to clean the carby in. And that's available in Oz..... I will try to pull it of tomorrow night, just incase some water got into the fuel bowl, during the cleaning process.


Cheers,

Phill.

Phill,
my D2 has a bushing in the top so I replaced that as well as the shaft, and for good measure drilled a grease gallery in the shaft: straight down the length of the shaft from the top, and then a small hole out sideways where the shaft passes through the bushing - should do the trick I think.

Good Idea Neil,

I will check my book to see if it already has a bush that I can replace, and I will definitely fit grease equipment. 😊

Hi Neil I have a 5u 4149 and I cant seem to find a bushing in my parts book do you know if this would of had one? I have mine pulled apart right now and would like to fix that slop as well. I cant figure out how to remove the shaft though...
Thanks God Bless
