Bits and Pieces

4 Jan

You may have noticed, particularly if you are a ‘hard’ copy subscriber, that I try to start TTT2 articles on a new page, or on a new half page and finish them at the bottom of a full page or half page. This normally works out OK, but depending on what articles I have for publication it sometimes works out that I have one or two pages left over which I can’t make fit. So now you have discovered the reason for the ‘Bits and Pieces’ page from your enthusiastic amateur!

Mention was made on page 6 of silicone hoses and I thought that you might like some further information about them. The best way to learn more is to go to the website of Silicone Classic Hoses.

However, mindful of those who subscribe to ‘hard’ copies and therefore do not necessarily have Internet access, I have included some photographs of the hoses.

The three finishes available (shiniest one is “standard black”)

TB/TC/TD silicone hose set in “classic black”

TF silicone hose set in “classic black”

The prices quoted on page 6 have been updated for the VAT increase. The TF hose set now costs £37.80 and the TB/TC/TD price has been held at £40. The price I quoted for a TB/TC/TF top hose (£20) is the price to me, which includes some discount. I am re-selling at the discounted price I paid (£20). The finish is “old style wrap”.

POLYURETHANE BUSHES

A couple of weeks before Christmas I supplied the measurements and specification for a mould to be made for the TC suspension bushes (those that go through the tube in the chassis, which takes the shackle pin and plates down to the rear of the front spring eye) and those that fit the rear eye of the front spring on the TC and the rear eye of the rear spring on the TC and the TD/TF. (The bushes would be cut to size)

The mould is not ready yet (these things take time!) but hopefully I should have some news by the next issue.

On the assumption that these bushes turn out OK, I will get a mould made for the large bush which fits in the housings of the rear shackle plates on the TC.

XPAG ROCKER COVER GASKET

Following a mention in Jonathan Goddard’s book on the TD, there has been a resurgence of interest in the Fiat 127 (or is it Fiat 124?) rocker cover gasket, which does the job on the XPAG after slight modification. Never mind which Fiat model, the part number is XF0004130541 Sealing Gasket and the price is £4.02 plus VAT. The gaskets have to come from Italy but your friendly Fiat dealer does not charge any extra for this. The details and price have been validated at Fiat dealers in Bristol, Milton Keynes and Poole, Dorset, so a ‘belt and braces’ job has been done on this!

SIDE TAPPET INSPECTION GASKET

Following receipt of the following query I posted it on a well known Bulletin Board:

“I wonder if anyone has any tips on how to make this gasket oil tight, despite pinching up it still tends to weep. I have thought about soaking a new gasket in oil before fitting or alternatively using a permanent gasket glue like Hermetite gold only along the lower section, any thoughts appreciated.”

By the way Loctite thread lock really cures leaking threads on the external oil unions”.

Unfortunately although I remember saving the replies, I can’t remember where I saved them!

From memory suggested ‘fixes’ were:

• First make sure that the tappet chest cover is not distorted
• Use a nitrile gasket
• Use a proprietary gasket sealant (can’t remember which one!)

Anybody else got any bright ideas?

    The mention of Fiat rocker cover gaskets brought back a recollection of using one years ago.The tip came up in the Octagon Club Bulletin in the mid 70’s.
    I have found the receipt dated 15/7/1977. Part no 4130541. Fiat 124 I recall.
    Cost 72p +6p vat (at 8%!) total 78p. It worked very well for many years.
    I glue the gasket to the head with silicone sealant, to minimise oil loss when removing the cover, and lightly oil or grease the cover so it will come off leaving the gasket unharmed.
    Be very careful not to let any silicone get squeezed out inside the cover when tightening, so use sparingly.
    I use the same technique on the tappet cover. Be careful not to overtighten this as it can distort the cover and/or strip the brass sleeve bolts.

    If you use silicon hoses make sure you use standard antifreeze. Antifreeze with organic acid anti-corrosives can damage any silicone in your engine including hoses.
    Cribbed from the internet.

    Regarding a sealant for gaskets and fittings, I’m using a product called EZ-Turn. It is a combination lubricant, sealant and anti-seize. Mattituck Aircraft Engine Service uses it when rebuilding small aircraft engines. They are, probably, the premier small aircraft engine rebuilder in the USA.

    Rebuilding an aircraft engine is probably closer to rebuilding a F1 engine then any roadcar engine.

    I apply a really thin coast to both sides of any gasket material. I also use it on all fuel and hydraulic fittings.

    It is easy to check it out in detail by doing a google search for EZ-Turn. I buy it from an aircraft supply company in the USA called Aircraft Spruce. They do have their own website. I’m sure it must be available from aircraft supply companies in the UK.

    EZ-Turn is also known as “plug valve grease”.
