Hi again - sorry second thread in a short period but this is an entirely different issue.

The rear fender on my '27 J is in pretty good shape overall. The hinged portion to the rear however had...

Hi all,

I am trying to lace an original '27 front hub to a 19 inch drop centre rim. This is the rim that came with the bike but the spokes when removed were an mixture of different types and were...

I am slowly restoring a ’27 J. A couple of days ago I hit a milestone when I finally buttoned up the gear case cover. I have an engine! Couple of photos attached
Whilst I have worked on the...

Steve,
If I can get the right hub I will certainly will go that route. I just was concerned that I would ever find a complete one in serviceable condition.
If Mark can help out on that then I will...

Thanks Mark.
I’ll get in touch

Thanks all. Since my original post I found reference to the change to rollers coming in 23 so it appears my rear hub has been changed for an earlier version at some point.
Unless I can find a...

Thanks Steve.
My hub feels like it’s an original and I’m pretty sure it was made for ball bearings much like the front hub just larger.
It may have been swapped out for an earlier model at some...

I am working my way through a '27 J rebuild.

When I dismantled the rear hub the bearing races were in very good shape but the bearings were just held against the outer race by the tension between...

Thanks all.


I have an OEM front hub with 0.160 spoke holes and a an OEM rear hub with 0.185 spoke holes. I don't want to mess with an original front hub by drilling out the spoke holes

I...

I am working on a '27 J

The front wheel hub outer bearing race is badly pitted on one side and not usable as is.

I picked up a used replacement hub shell which is identical in every way except...

I have just come back to this thread and have picked up on the comments generated. I cant really add much to my original observations about the fitment of the kit parts.

The proof of the pudding ,...

I am restoring a 27 J. When I dismantled the engine one of things I found was that the rollers that run on the cam lobes were badly worn. In fact the whole roller arm mechanism was worn which was...

Thanks all for your input and comments.

I had planned to use Permatex to seal the thread, as much as anything as I have some on the shelf left over from another job. I will take a look at Fluid...

Thanks for the input.

Since I started the post I have pulled off the oil pump and found that I had fitted a repro gasket. Not sure which make but much thicker than the original paper version that...

Thanks for this input. since the thread started I dropped the oil pump off. I found when I last fitted it that I had used a repro (not sure which make) fibre or rubber gasket.

In any event it was...

Hi all,

I am just getting the parts together to rebuild the top end of my 27 J. I plan on using new valves, guides and valve springs for intake and exhaust - among a long list of other new parts....

Thanks all.
Steve, T&O did not fit the pinion bushing for me. I kept the cases here in the UK to work on while they built the fly wheel assembly. I found an expert machinist who was able to sort out...

That’s good further information thank you. Who is the author of ‘motorcycles and side cars’ ?
I imagine it’s long out of print but worth looking out for a copy
Thanks
Martin

Steve,
That’s great thanks. As and when you get a chance I’d sure appreciate the further information stored in you files. At least I know now that it needs something in there.

Martin

After discovering a cracked fly wheel (T&O did a great job rebuilding the flywheel set up) and then a badly repaired sprocket shaft outer race, see my earlier post on April 28th, the bottom end of my...

Thanks Steve,

That would be very helpful

Thanks Larry, that’s useful.
Clearly not the same guy I met at the AMCA rally in May.
Appreciate your comments and help

Martin

Thanks Larry.
It’s a while since I had the pump apart but as I recall I refitted it with a repro standard paper gasket.
The pistons are fitted with two compression and one oil ring each and I...

Larry,
I believe so. It is the style of pump with the two check valves and the pump rotor has the little plunger that’s sits under the vanes.
I should have added that the pressure regulating...
