This topic was the subject of an article in Totally t type Issue 61 August 2020. Part of the problem in currently available replacement parts was the inadequate depth of the groove for the circlip.

There's an article on coil polarity in Totally T Type 2 Issue 57 December 2019
https://ttypes.org/a-clarification-of-t ... on-system/ that provides some answers.

There's an article in Totally T Type 2 https://ttypes.org/xpag-oil-pump-circlip-replacement/ that covers the circlip issue. Original circlip groove depths in the drive shaft were much deeper.

The rope seals provided in some gasket kits are too large, measuring some 10mm X 10mm. The correct rope seal dimension is 8mm X 8mm, these can be found on ebay under graphited gland packing rope seals. You might need to buy a 1 m length and cut to size with a sharp scalpel leaving the ends slightly ...

There's an article in Totally T Type 2 issue 61 August 2020 which looks at the circlip problems. The groove for the circlip was found to be too shallow in the replacement drive shafts. However, over-stretching of the circlip when being installed was suggested as a contributory factor to circlip fail...

Agree with Steve, no real advantage in fitting it other than for concourse inspections. Far better to allow the odd viewing of what's behind the dashboard. Also the weight reduction would improve the acceleration :=))

Hi Steve, One possible explanation is that the internal shoulder that locates the outer ball races in the wheel hub is worn, so it is slightly shorter than the spindle's spacer. This would allow some end float of the hub along the spindle which could give the impression of play in the bearing. Is th...

Steve suggests the front wheel end play is 2-3 thou. which seems very difficult to measure, a more useful measurement might be the amount of movement at the wheel's rim. This would be an amplified version of the end play, consequently easier to measure. Roger Furneaux of "Mad Metrics" offers a set o...

Hi Mike, If one is fitting tapered bearings on a replacement stub axle spindle, the spindle journals can be polished with a strip of fine emery paper (400 or 600 grit, oiled) to allow the inner race of the bearings to be a hand push fit. This is especially true of the outer bearing which will need t...

Hi John, The king pins sets available from most retail outlets are about 0.5 thou. undersized. Doesn't seem much, but the slight rocking of the loose king pin results in the axle eyes becoming worn. This is a difficult and expensive issue to sort out. You cannot rely on the cotter pin countering any...

There's a bit more detail on the circlip problem in the web based Totally T-Type 2 Issue 54 June 2019. Try http://ttypes.org/ttt2/xpag-oil-pump-rebuild. From your description you have an end float of just 2 thou. in the shaft, but what is the gap between the pump's body and the skew gear on the driv...

I've noticed on some installations that the lip-seal only just engages with the flange of the crankshaft. It can be so marginal that two spacers are available of 1mm and 1.5mm thick to offset the lip-seal and increase engagement. The downside to such an approach is the need to skim the surface of th...

If you wish to protect bare metal panels whilst manhandling them, then consider a rust convertor called Fertan. Although your panels may not be rusty, Fertan will still apply a zinc phosphate layer that protects the panel for many months. When you come to prime the panel, the Fertan film can be easi...

Tom makes an important observation about caged needle rollers. Early TCs and possibly all TBs used caged layshaft and first motion shaft roller bearings known as Hyatt bearings. These eventually break up as the small nipples that locate the individual rollers in the cage wear away. This can be catas...

Next time you visit your dentist, scrounge some of the felt buffers that are sometimes placed between the teeth and gums. These are about an inch long by 3/8" dia. and provide an effective oil resevoir for the sintered bronze bush.

Hi Kam,
The initial surge starter current could be as high as 250 amps, which as previously stated would bring the carbon brushes up to "glow" temperatures. The brushes are only used sporadically, so no great wear takes place especially if your engine "fires up" quickly.
Eric.

Thanks also Steve for your photo which comfirms that Pat's push rod was too short, thus forcing the push-rod's adjustment thread to be screwed out so that the ball joint was far below its correct position, resulting in the inclined push-rod. Pat, you've picked up on and solved a particularly tricky ...

Hi Tim, As no one has come up with a suggestion, you could try maching a groove in some hard wood with a round nosed router bit, place the slat in the groove, place a round metal rod on the slat and press down on the rod to force the slat into the groove and take up the groove's curvature. Just a th...

I don't think there's any need to be concerned about providing adequate field current at start up as the field contacts in the regulator are initially closed, directly coupling the dynamo output to the field winding.

Afternoon Pat, There should be a return spring on the brake pedal ( in addition to the brake switch spring ), which ought to return the pedal so that it comes to rest on a stud, defining the position of the pedal at rest. The push-rod adjustment is then altered so that about 1/2" of play of the foot...
