... this might have something to do with it..

That's a lucky one to extract off the main shaft!
Are you going to change the bearings while you're in there?
All looks good work goin on.. Well done man!

Oh Snap!! That was lucky it held together until you got to it. That could have taken a lot more with it under load if it had disintegrated.

Wow, what a mess...

I wish I had the courage to strip my box down, the bearings on the shaft (1st and 2nd gear) have been rasping a bit all through the 13 years of my ownership, it’s not got any worse in that time and all the gears work OK, so I’ve learned to live with it.

Brave man going in there Mike

What’s the box like for a rebuild? I have pretty poor synchros in 1 and 2 and I can fell 3 getting a bit rough too. I’m tossing up whether to buy a second hand box or do a rebuild, but I feel like either way will be time and money.

Hi Opie. There is an "early" stiff synchro box or a later one which has improved design. If you have the early one changing the synchros will make no difference. Been there and done it.

 

[Towpack]

The synchros in the later 80 box may have been improved but aren’t problem free. The 100 series box is supposed to be improved further.

I have a 100 series box and it's fault free I have to say. I just need to find time to put it back in the truck sometime. I did one trip with it and it was a sheer delight. But the current one isn't so bad that it makes me want to do the work

thanks mate.
this is a pals gearbox. he just wants it back to good health as cheaply as possible. its not a project box.
its always been quite and they feel fine so will be staying.

its not too bad. make sure you correctly identify which gear is which and you know where you are on the diagram before you start ordering parts.
take your time.
be very methodical.

Thanks for the tips on box types guys. I have been trying to decide what is better between a 2nd hand unit and a rebuild. Is the 100 box still an H151? Is it a straight swap on the 1HZ? Thanks again for your info.

Some gearbox goodness.

 

[Chris]

Yum!

Just to conclude.
This has been up and running for a while now.
Works a treat!

 

[clivehorridge]
