Stuff you have fixed today

[Brad93]

That was my thinking too.

I think the standard bearings have tighter clearances when cold which should suit this application.

I doubt anything but standard bearings were used in the pumps construction. Bearing clearances have only become the topic of serious debate with the advent of monitoring equipment and techniques that were not possible 30-40 years ago.

I think alot of the problems with bearings nowadays in how, where and to what standard they are made. How come so many old brooks, gec, metropolitan vickers motors etc are running on original bearings with less than ideal maintenance intervals. Old Hoffman, R&M etc bearings were completely ground/lapped, every surface. Nowadays, its quite common to see only the ID/OD and raceway ground. The seal area and grease area are rough machined, the faces are just blanchard ground pretty rough.

Finished off this box today:

It arrived a week ago looking a bit more tatty:

and contained this level:

The main brick laying sensitivity level has been removed (undamaged!) as well as the yellow one at the end, I've cleaned it up and scraped the bottom flat as it was far too far out for the 0.02mm/m vial I'll be fitting to it. The pic was taken during scraping, it's a bit better than that now:

Small wins today.
Managed to convert this, complete with seized pins, and one sheared retaining bolt -

Into this -

Through the use of the TIG to provide a bit heat -

Also found out why one of the wheel bearings was feeling a touch rough...

Might get the driveshafts UJs changed tomorrow, and get the hub carriers back on, ready for the next batch of parts arriving, or if I feel motivated enough (I've finally succumb to the cold/flu that's been doing the rounds :/ ), I might get the rest of the front axle dropped off, and change the main pivot pin and bushes to try and reduce the slight 3/4" play between the axle and buffer plates.

Finally got some space in the workshop and the RR outside without any air leaks seemingly...

Brake Caliper season for me recently, people think you can treat a Motorcycle like a car and get away with it.

First one, pistons seized into calipers. Took them to bits to find someone had pulled the dust seals out at some point (typical bodge it and scarper hack..). Pad pins seized into calipers.

The last one was a 900cc Triumph, bald front tyre and front brake "has a sandy feeling". Pads worn down to metal backing ffs and pistons seized into caliper body.

Chain was hanging off as well so he's having to wait for new chain and sprockets to arrive..
Amazing what people will ride around on without checking even simple safety stuff like brakes and tires!.

Some people begrudge paying for an annual service but both these would have been nipped in the bud long before they got this bad.

Piaggio MP3 500 Steering tower service.

Came out of the factory with wrong bearing pre-load and seems no-one else will repair them so a fair few end up on my bench..

If you catch them early enough it's a couple of hours, if the bearings are too far gone (brinelling), it's a days labour to strip it all down and replace them.

They should have all be done on PDI..

Customer snapped off 2 exhaust studs when "taking his exhaust off to clean it".

They were stuck solid (tried heating the head with no joy), engineer wanted the head removed to mill them out (can't blame him really).

I managed to drill them both our to 6.3mm and run an M7x1.0 thread down (basically making a tread insert in situ). Early Honda Fireblades use an M8/M7 hybrid stud so two of these worked a treat.

Probably took me an hour a stud but worth it to avoid taking the head off! (plus the cost involved with that).

Personal I'd have cut the nuts off the studs to start with but damage already done.

Cutting rotten exhaust nuts off a Truimph to save the studs.

Not the nicest of jobs but best way round it imho.

Saved all the studs and fitted stainless dome headed nuts when exhaust was refitted.

Looks like a Renault M9R engine?

 

[qwakers]

yup.

old engine was in the process of going bang, big time.

I saw pictures the other day of someone who did 2 x 30 mins on track in the USA with a heavy, powerful rear drive car - started with front pads around 70%.

Finished with the pad material totally gone, and on one caliper, there was a hole melted through the backing plate and the piston was starting to be melted/worn down!

I have no idea how the brake fluid remained liquid enough to continue to operate that caliper well enough to do that! Or to not be noticeable as horrendous brake fade and not slowing down, heading to the scene of the accident!

That looks a lovely clean workshop. Freshly painted walls and floors by the looks!

You want to get a tig welder for them snapped studs. Would of had them out in no time.

I have a real soft spot for a proper bike engine……but not the near death experience when I rode one!

Fit some brass nuts.

Over two days, yes two goddam days of sheer mechanical hell, I finally finished my Pug 406 clutch change.

I'm really not a car mechanic, oh no, made some fine mistakes, but my guardian angel, the retired ex owner of the village Peugeot garage, helped me, or I would have dragged thé car out works garage, and torched it.

Thumbed it to work this morning, not done that in a while.

Managed to break this plastic fitting on the thermostat housing, cleaned up, epoxy resin, I ordered a new one this evening, as it may last but I doubt it.

Only issue I'm having, one of the gear sélection linkages keeps popping off, but I'll find a solution, métal clip I suspect.
