MG TD TF 1500 - Dip Stick Tube Length - TDs

"Bud Krueger , Massachusetts, USA, budkrueger@comcast.net
It's a puzzler. As far as I can find out there is only one dipstick. Here's what I found, Engine #28839:

TD Dipstick Oil Level vs. Indication
Note: Dipstick is Part # 24407
Refer to W.M. Fig. P.1 on Page P.1

Quarts Height (in.) Dipstick Indication
1 5/8” None Above sump bottom
2 1.25” None -do-
3 1.75” None -do-
4 2.5” None -do-
5 3.25” Empty mark
6 4” ~2/3 Between H & A
6.5 ~3/4 At ‘L’
7 Full After engine run
7 Full + At U after sitting

Peter's thought is one that I share. Perhaps we can start a thread asking for the height (length?) of the dipstick tube as a function of engine number. Bud"

XPAG/TD2/25404 (TD25009)
Tube - Block to top: 4-13/16 +/- 1/16" Hard to hold the rule, the flashlight and read the ticks.

Dip Stick - underside of cap to tip: 11-7/8"

If the cap to tip varied the readings would vary even if the tubes are all the same length.

There are two (2) different length dipsticks used on the XPAG

The longer one (24407) goes into the tube on the side of the engine block with the larger sump, the shorter one (and I don't have the number close to hand) fits the earlier block/smaller sump and there is no tube to go into.

Hello Gene, My TD (engine #11249) has the small non-finned sump, with the longer dipstick and tube. I always thought all TD's had the tube and longer stick? Will have to research. George
George Butz

George,

Maybe I'm wrong...but I know one engine has a tube and one doesn't, one has a small sump and one has a large one.

Here is my info:

My block is 21906 (last digit could be an 8) and has a finned sump. Its supposed to be 19988 but that's another story told elsewhere.

My dipstick is #24407. See picture below.

The total measurable distance is about 12 1/8", which seems to be about 1/4" longer than Jud's for the same disptick. Typical manufacture difference I would say.

I can only put 5+ quarts of oil in my car.

My dipstick tube is about 4 1/2" long but as Jud says, its hard to get an exact measurement. Also to note that I can get at least 3/16" of further setting of the dipstick if I rotate it where the logo is upside down.

Hi Jud,

These are my dimensions on the dip stick in my 53 TD Engine No 26335 Body No 25928
I did note there is a rubber/cork seal in the cup. Which may account for the slight push in change noted by Chris.

And BTW, I live just North of Lewiston about 10 miles :) As you had asked.

Ah, if only we could merge two threads. I've contacted a friend, and occasional poster, Paul Hinchcliffe, to ask about this. Paul has a late TC and early TD. Bud
Bud Krueger

My bad. I thought a new thread was desired.

Here's what I received from Paul Hinchcliffe from his TC and early TD:


TC 5130 engine #5811 matching
NO tube
Dipstick part # 24164

TD 5357 EXLU engine #6708 matching
YES Tube, approx 9.5 cm high
Dipstick part # 24407

attached image # 1975 shows overall length of sticks vary in many ways
TD at top, TC below

attached image # 1982 - Measuring ends against ruler

Images of the dipsticks:

Only odd thing is the measurement of the early tube at 9.5cm (about 3.75") Bud

Car # TD3042 Engine 3304 Dipstick # 24407 Early unfinned sump:

Length of dipstick tube to entry in block: 4-1/4"
Mark 1 (from bottom of dipstick) 1/8" marked EMPTY
Mark 2 at 7/8" marked HALF
Mark 3 at 1-5/8" marked FULL
From tip to inside of stop: 12-1/4"

Overall length: 16-7/16"

I have been following this thread with interest as I am using an XPAW block with the long XPAG sump and have had to drill through the XPAW block to fit the dip stick and was wondering how far I should be inserting the tube into the block.

From reading the comments above there is no consensus (4 13/16" (say 4 3/4), 4 1/2" and 4 1/4") as to the length of the tube out of the block.

Can we have later MD owners/members with long sump measure the length of their car's dip stick tube out of head.

Also any suggestions on how to fix the tube in block where the hole is slightly bigger than the outside dia. of the tube.

Stuart,

My car is TD24953. Original engine #25330. My block is out of the car and stripped down. So it was easy to get a measurement. I get 4 3/8" from the block to the top of the dipstick tube. The measurements will vary if they are not taken from the same side of the tube. I measured the side 180 degrees away from the block.

Having just used a similar process to refurbish TF door hinges, this may rectify the oversize dipstick hole drilling in your block.

Establish the diameter differences between the hole in the block and the dip stick tube, source a suitable steel, brass or copper tube with an ID that will go over the dip stick tube and an OD greater than the hole diameter. Silver solder the tube sleeve onto the dip stick tube, you will only need to solder approx 10mm at each end of the tube. Providing you use and apply the correct flux on both components, silver solder will flow and penetrate down the ends by this amount.

Machine the sleeved dip stick OD to obtain an "interference fit" in the block hole.

I achieved a similar result by using brass shim rolled and silver soldered into over sized holes in my door hinges, degree of difficulty was reduced to your job because the bearing surface lengths were only short. Fabricating stainless steel hinge pins has assisted in providing a quality outcome.

I took some measurements and did a little estimating (sump wall thkns, angle of the stick etc) and came up eith the attached. I came up with approx capacity same as Bud Krueger above. At full cap is approx 5.5 qts US. At empty 3.25 qts approx.
Sketch attached.

Peter Dahlquist

Peter: Vary nice diagram. What you depicted aligns with my findings on my later TD2.

So I am still struggling to find out where those who are needing to put in 7+ US quarts of oil are placing it and what geometry (the pan?) is causing this.

We may need to turn this into a oil pan height question assuming that the width and length are standard. Could there be more than one finned sump?
Christopher Couper

In my measurements it took 5 quarts to reach the empty mark on the dipstick. At that point the height of the oil on the wooden rod measured 3.25". I don't see a correlation between Peter's diagram and my data. In a short while I'm going down to the garage to measure the length of the dipstick tube on Lazarus' engine. Bud
