[TR] Front Pullet Hub Removal

Mon Jul 19 13:31:18 MDT 2021

Some oil seals have the metal part covered with rubber, so you don’t see the metal.  Check the OD of the original seal and the replacement seal and I think you will see they are the same.  You had to remove the metal part to install the new seal.

Thanks Steve.  My oil seal is from TRF and does not have a metal housing.  The factory TR4A parts book references 56763 as “Support, timing cover. It’s listed near the oil seal and TRF thinks that is the part.  Will get the fiber washer too and a speedi sleeve since I do have wear marks from previous oil seal.  Thanks all for the tips.  I normally don’t do engine work, but I am feeling brave and this isn’t my daily driver.  How nice it is to walk away when frustrated and grab a beer and not worry about getting the car running to use next day.

The metal “housing” is part of the seal.  Moss 520-000.  Also order 324-680, the seal for the pedestal stud mentioned by someone else, plus the other components.

Cliff:
Thanks for the tips.

List:
The oil seal was inside a metal housing pressed into the timing cover.  I had a heck of a time getting it out and damaged it slightly.  See attached pictures.  Seal1.jpg shows it removed but resting on opening in orientation it was installed.  I don’t see this part listed on Moss or TRF.  I am assuming this is the oil seal housing that needs to be reused with new seal.  Thoughts??

Thanks in advance

Would that bushing be from the rear of the crankshaft, where the input shaft of the transmission rides? If so I also have one in my bin, and that’s a good tip.

From the other email, I take it you are already planning to remove the timing cover to replace the seal. I would replace the timing chain and tensioner, they are not expensive.

The hub pulley may need a speedisleeve if the old seal has worn any  kind of groove.

When you replace the timing cover, there is a stud in the middle that has to have a fiber washer and gasket sealer between the shoulder on the stud and the timing cover, otherwise oil will leak at this spot.

I did this job about two years ago, leak free since and that’s a good feeling.

Cliff, so true.  I’m refreshing the 72k orig mile 4A and I definitely run into the “while I’m there, let’s fix this too so I don’t have to go there again for another 20 years.

I took the extension and large crank bolt out.  I had a 2 inch long thick bronze bushing that fits perfectly on my pulley bolt and flush against the crank.  That provided the strength to pull the pulleys and hub free.

Thanks, Jim

The pulley hub is keyed to the front of the crank and probably adhered with years of crud. My guess is that’s what sticking. Some PB Blaster, and a few raps with a mallet (I use a deadblow) may persuade it. It’s difficult to use a puller since there’s nothing in the center to push against, unless you can find a short bolt to thread in where that large dog bolt was removed.

Since you are in there, if there’s evidence of oil leaking from the timing cover, it’s most likely from the seal between the cover and the pulley hub. But I can see how changing that seal would slide into even more work (hey there’s the timing chain, I should replace that…)  BTDT.

Here’s hoping the pulley hub cooperates.

Cliff,
Yes, I removed the crank bolt.  The pulley seems pretty tight.  Will see about getting it off today. Thanks, Jim

Jim,

I take it you have removed that enormous bolt through the extension. The stock pulley is a two part assembly. You remove the 6 bolts through the hub and pulley halves. Then it just pulls off the front of the crank.

List:
Converting my 67 4A over to the Bastuck narrow fan belt kit. This kit
retains the fan extension tube and fan.   I have the radiator out and fan
blade and fan extension removed.  I have the stock pulley at the top dead
center position (hole at the top).  Have not removed one of these before.
Any tips on removing would be greatly appreciated.  I still have the cross
tube and was hoping it could be removed while that is still installed.
Thanks in advance!
