TD9-91 engine clutch weight

[td9bcf180]

25-30 pounds?

...with respect,you are not 'clutching at straws'......

..now I cannot say for sure..but I would suggest that is a little on the light side...

Perhaps double those numbers, Mike. Instead of adjusting the pressure plate on a clutch that I know nothing about its history- I am going to remove and inspect, possibly today, and report back. My question in regard to the weight was concerning the use of utilizing a set of chain blocks vs. my small "crane" vs. "lifting it out by hand and back". I don't think the crane will "fit" or "reach" the situation anyways. The dozer is about a half hour drive from here. I will rig up a lift of some kind attached to the sad ole canopy on said beast.

When I purchased this 1956 TD9-91 in May 2024 I knew that the clutch lever was lacking that good "snap" into place feeling and after a good work out opening old bush roads these past few weeks, well, it has no "snap" at all.  At best, when removed, a good cleanup will suffice but if there is substantial wear on the parts- replacements will be made and another 69 years can be attained for the next owner.

I'm late- out the door soon. Waiting to get knuckles busted up.

Cheers.

Stuff will wear and the throw and snap point is adjustable but you do use your equipment for work so maybe a better look at things in there is warranted

The Rockford clutch on my 150 had good wear on the pins and connecting links. No parts to be found. I made the links out of tool steel and used hardened dowel pins for the headed pins. I put a keeper groove in both ends to replace a head.

That coupling in there is a wear item that is reproduced, I changed mine. Good luck with your job!

..its not that easy to adjust that master clutch......with the pig iron adornment,  however  on the straight agriculture set up , it was not so bad,,,@just Dave would have had to utter a few bad words when battling with his track loader clutch.....The track loader models are bloody hard to do any ''back end ' type work ,on...

Be prepared to give blood Mike ....in your quest for perfection ...

The clutch is out- everything went pretty good- no blood, Mike, but a few bruises. 

I'm glad that I took it out as it was wet in the bottom from a leaking front transmission drive shaft seal so that will be replaced. The clutch and pressure plates seem OK but the splines are bad on the driven plate. See the pics and tell me what you all think. Thanks.

 

[int 504]

What do the splines on the shaft look like?

[td9bcf180]

Very good condition as far as I'm concerned.

[td9bcf180]

Having issues getting the front transmission driveshaft seal 279749 R91.  TD9-92 series parts book says that 310508R91 will work (same tranny I guess). My local NAPA crosses this to 21134 which is not available anywhere here in Canada.  Are there any other cross reference #'s with you folks in the US ?  Thanks.

21134 is the right seal#, I bought them from NAPA with both NAPA and SKF on the box, so check for an SKF cross number and you should find something. Hard to believe that NAPA doesn't have one.

21134 seal seems all over on google search under several brands .    The end of the stub looks good. The clutch teeth seem thin. How does the shaft fit?   I think I would have to surface that polish surface off my flywheel and pressure plate, if I was in that deep.  You could break the glaze on the flywheel with a hand grinder and a 36 grit soft pad, if you are carefully even.  

[hardtail]

Maybe try Motion or online for the seal? Motion and Amazon both show stock for just over $40

[hector gemme]

The drive shaft seal should be 310522r91 and 279749r91 and 310508r91 will work for seri 92 and serie 91 oil seal should be 273573r91

[td9bcf180]

Thanks for all the advice- appreciate it.

The splined shaft fits tight through the pressure plate (I have it on backwards in the photo but its the same wear either way) except for the last 2 or 3 inches where the teeth are worn the worst on the pp.  The linings are not down to the rivets so I have a place I can take this to on Monday to see if they can perhaps replace the center section (or the whole PP at the worst).

Still working on the seal. 

[td9bcf180]

I ordered the seal I discussed, above, last Friday but when I pulled the old one out this morning its stamped "DFR30024  with a Patent # 545369. Can't see a Mnftr. name on it.  When I get to my supplier tomorrow I will show him this one and cross ref. to see if it matches.  This is a weird # I can't find anywhere on the good ole web.

Also- another question- when I removed the seal holder with seal I exposed (naturally) the input shaft into the transmission and it has approx. 1/4 inch end play on it. Is that normal? Thanks.

[td9bcf180]

Update- I am in this far with engine clutch and flywheel that the motor is going to be yanked out (or a few feet ahead), the rear engine seal changed and the flywheel removed and refaced properly. (I have had nightmares about taking a grinder to a 70 year old cast housing).

So- it shall be done properly.  Might take me a while yet as I'm getting slower- but I will report back in due time.

[td9bcf180]

Anyone have a part # for rear crankshaft seal kit for TD9-91 series with D350 engine? I don't think the older TD9's with D335 motors are the same.

[hardtail]

I thought that style engine was all felt? I thought KOO made his own?

You're right-KOO made his own and they were felt. He has the earlier TD9 cats. I have been in contact with him since my last post on Wednesday). This is a 91 series (early 91 series- early 1956) so it has either a grooved seal on the crankshaft for felts or smooth neoprene type seal. I wont know what I have until I pull the motor looks like early next week now. Stay tuned.

[td9bcf180]

OK, so the motor is finally out and my rear crankshaft seal is a neoprene lip type seal NOT felt used in the older TD9's. I have a few inquiries out there for this seal which comes in 2 pieces or "half moons" so to speak and is part # 271703R91 according to the parts book. Is anyone familiar with a seal/gasket kit with everything included in one package for the rear crankshaft?  Also please look at the one picture of the seal pulled part way out of the housing- there is another part (brownish) in the cast housing but this needs to come out too, right? It's part of the seal I think.

 

[td9bcf180]

Update: 

Here it is almost a month later and I should have the rear main seal kit delivered to me on Monday. BUT that ain't gonna happen! The seal originated in the US and was shipped to my supplier in Canada. My supplier is about 1200 miles away from me. They put it in the regular mail for shipping (no issue with me) and then right out of the blue the Postal Union here in Kanada goes on strike. So my seal is sitting in limbo land. (The reason for the strike is that the Guberment announced they would stop all home delivery of mail and start closing post offices. No comment here as its a political matter but you can read my thoughts on this one).

Anyhow- ole TD9-91 is well bundled up with tarps sitting in the bush. Could have snow in 5 or 6 weeks so I hope I get my seals before then.

[Rawleigh99]

Wow, what a bummer! 😕 I hope you get it before the weather shuts you down.

[td9bcf180]

The postal strike is still on here so I found another supplier from California that has sent me the seal kit. Should arrive Wednesday. Now I will have 2 of them but that's OK. Just got home yesterday from a 4 day hospital stay with major surgery involved so could be another week until I'm up to the task anyhow.

Crazy world we live in, EH ???
